Uso y complicaciones del cateterismo urinario en salas de cuidados moderados de un hospital universitario

Introducción: El cateterismo urinario es un procedimiento frecuente y en ocasiones es utilizado por fuera de las indicaciones aceptadas para el mismo. Esto aumenta el riesgo de complicaciones vinculadas a su uso, por lo que pueden ser prevenibles. El objetivo del estudio es conocer las características del uso de cateterismo urinario en pacientes ingresados en salas de cuidados moderados de un hospital universitario del tercer nivel de atención, determinar la frecuencia, duración e indicaciones más frecuentes, así como evaluar la presencia de complicaciones asociadas al mismo Metodología: Estudio de corte transversal, realizado en salas de cuidados moderados de un hospital terciario y universitario de Montevideo, Uruguay, el 21 de diciembre de 2022. Se incluyeron pacientes hospitalizados que presentaban o presentaron catéter vesical en la presente internación y se completó la recolección de variables mediante la revisión de la historia clínica. Resultados: De 155 pacientes ingresados en salas de cuidados moderados, a 26 (16,7%) les fue colocado un catéter urinario. La mediana de edad fue 61 años, 80% eran de sexo masculino. La mediana de internación fue de 22 días. En todos los pacientes se utilizó sonda vesical y el 54% fue colocado en el Departamento de Emergencia. En el 46% de los pacientes no se encontró indicación escrita de colocación en la historia clínica. En 50% de los casos no está especificado el motivo de indicación de sonda vesical, mientras que las indicaciones identificadas más frecuentes fueron el control de diuresis (27%) y la desobstrucción de vía urinaria baja (23%). La duración de cateterismo fue de una mediana de 13,5 días, mientras que el 27% de los pacientes la usaron más de 30 días. 35% de los pacientes presentaron complicaciones vinculadas a la sonda vesical, en su mayoría no infecciosas (27%) y 15% presentaron infección urinaria. Estos pacientes tuvieron una duración de cateterismo mayor a los que no presentaron complicaciones (23 vs 10 días, p=0,411). Conclusiones: El catéter vesical fue utilizado en un porcentaje no despreciable de pacientes ingresados en salas de cuidados moderados, de forma prolongada y frecuentemente sin indicación precisa, lo cual expone a un riesgo aumentado de complicaciones vinculadas.

Introduction: Urinary catheterization is a frequent procedure and is sometimes used outside of its accepted indications. This increases the risk of complications related to its use, so they may be preventable. The objective of this study is to know the characteristics of the use of urinary catheterization in patients admitted to moderate care wards of a tertiary care university hospital, to determine the frequency, duration and most frequent indications, as well as to evaluate the presence of associated complications. Methodology: Cross-sectional study, carried out in moderate care wards of a tertiary care and university hospital in Montevideo, Uruguay, on December 21, 2022. Hospitalized patients who present or presented a bladder catheter during the present hospitalization were included, and the collection of variables was completed by reviewing the medical history. Results: Of 155 patients admitted to moderate care wards, 26 (16.7%) had a urinary catheter placed. The median age was 61 years, 80% were male. The median hospitalization was 22 days. In all patients a bladder catheter was used and 54% were placed in the Emergency Department. In 46% of the patients, no written indication for placement was found in the clinical history. In 50% of cases, the reason for indicating the bladder catheter is not specified, while the most frequent indications identified were diuresis control (27%) and lower urinary tract obstruction (23%). The duration of catheterization was a median of 13.5 days, while 27% of the patients used it for more than 30 days. 35% of the patients presented complications related to the bladder catheter, mostly non-infectious (27%) and 15% presented urinary tract infection. These patients had a longer duration of catheterization than those without complications (23 vs 10 days, p=0,411). Conclusions: The bladder catheter was used in a non-negligible percentage of patients admitted to moderate care wards, for a long time and often without a precise indication, which exposes them to an increased risk of related complications.

Introdução: O cateterismo urinário é um procedimento frequente e às vezes é usado fora de suas indicações aceitas.

Resultados: Dos 155 pacientes admitidos em enfermarias de cuidados moderados, 26 (16,7%) tiveram um cateter urinário colocado. A idade média foi de 61 anos, 80% eram do sexo masculino. A mediana de internação foi de 22 dias. Em todos os doentes foi utilizada sonda vesical e 54% foram internados no Serviço de Urgência. Em 46% dos pacientes, nenhuma indicação escrita para colocação foi encontrada na história clínica. Em 50% dos casos não é especificado o motivo da indicação da sonda vesical, enquanto as indicações mais frequentes identificadas foram controle da diurese (27%) e desobstrução do trato urinário inferior (23%). A duração do cateterismo foi em média de 13,5 dias, enquanto 27% dos pacientes o utilizaram por mais de 30 dias. 35% dos pacientes apresentaram complicações relacionadas ao cateter vesical, em sua maioria não infecciosas (27%) e 15% apresentaram infecção urinária. Esses pacientes tiveram uma duração mais longa de cateterismo do que aqueles sem complicações (23 vs 10 dias, p=0,411). Conclusões: A sonda vesical foi utilizada em percentual não desprezível de pacientes internados em quartos de cuidados moderados, por tempo prolongado e muitas vezes sem indicação precisa, o que os expõe a um risco aumentado de complicações associadas.

Antibiotics prophylaxis at the time of catheter removal after radical prostatectomy: a systematic review of the literature and meta-analysis

Purpose: To conduct a systematic literature review with meta-analysis to identify whether antibiotic prophylaxis after removal of the indwelling urinary catheter reduces posterior infections. Methods: A systematic literature review was conducted in the databases PubMed, Embase, Cochrane, Google Scholar, and Latin American and Caribbean Health Sciences Literature, using the keywords "antibiotics" AND "prostatectomy" AND "urinary catheter." Results: Three articles were identified having the scope of our review, with 1,040 patients, which were subjected to our meta-analysis revealing a marginally significant decrease in the risk of urinary infection after indwelling urinary catheter removal (odds ratio-OR = 0.51; 95% confidence interval-95%CI 0.27-0.98; p = 0.04; I2 = 0%). No difference was found regarding the presence of bacteriuria (OR = 0.39; 95%CI 0.12-1.24; p = 0.11; I2 = 73%). Conclusions: In our meta-analysis, there was a significant decrease in urinary tract infection with antibiotic prophylaxis after indwelling urinary catheter removal following radical prostatectomy.

Riñón pélvico fusionado con uréter único, hidrometrocolpos y ano imperforado: conjunción de malformaciones infrecuentes en una adolescente / Pancake kidney with a single ureter, hydrometrocolpos, and imperforate anus: a set of uncommon malformations in a female adolescent

Una niña de 11 años de edad con antecedentes de ano imperforado, infección urinaria y episodios de constipación intermitentes se presentó a la consulta con cólicos abdominales y náuseas de una semana de evolución. Estudios radiológicos revelaron hidrometrocolpos y fusión renal pélvica con uréter único hidronefrótico. El examen vaginal evidenció un tabique transverso no permeable. Se evacuó temporalmente la colección con resolución de los síntomas. La paciente fue programada para cirugía vaginal reconstructiva definitiva. Se destaca en este caso no solo la asociación de malformaciones infrecuentes, sino una sintomatología muy común en la práctica pediátrica a causa de una patología rara vez considerada en el diagnóstico diferencial, y la importancia de una evaluación precoz y completa de este tipo de malformaciones para un tratamiento oportuno.

An 11-year-old girl with a history of imperforate anus, urinary tract infection, and intermittent episodes of constipation presented with abdominal pain and nausea for 1 week. The x-rays revealed hydrometrocolpos and fused pelvic kidney with a single hydronephrotic ureter. The vaginal examination revealed a non-permeable transverse vaginal septum. The collection was temporarily drained and symptoms resolved. The patient was scheduled for definitive vaginal reconstructive surgery. In this case, it is worth noting the association of infrequent malformations and also the signs and symptoms very common in pediatric practice due to a pathology rarely considered in the differential diagnosis, and the importance of an early and complete assessment of this type of malformations for a timely treatment.

Prevalence of antibiotic resistant UTI in immunocompromised patients

Background: Urinary tract infections (UTIs) are amongst the most common bacterial infections, affecting about 150 million individuals per year.Urinary tract infection (UTI) is one of the most common diseases in human societies which occur in women more than men. Women of all ages are more likely to experience such an infection than men, while half of them may be affected by a uropathogen once in their lives, and 25-30% may develop recurrent UTIs not associated with any functional or anatomical abnormality. The aim of this study was to explore the prevalence of antibiotic resistance of urinary tract infections in immunocompromised patients. Material & Methods: This was a retrospective observational study and was conducted in the Department of Medicine of Dhaka Central International Medical College and Hospital, and National Institute of Kidney Diseases & Urology, Dhaka, Bangladesh during the period from June, 2021 to June, 2022. We included 70 immunocompromised patients with UTI. Results: In our study we found 44% patients were aged between 18-30 years old and 83% of our patients were female. Among all respondents, 58 patients were culture positive. We found 38% & 62% and 33% & 67% had history of upper & lower UTI in female and male patients respectively, 29% & 36% and 17% & 25% had urethritis & cystitis in female and male patients respectively. We found culture positive patients with E. coli (41%), Klebsiella spp.(19%), Enterobacter spp.(16%) and 12% with Pseudomonas spp in our study. We found amoxicillin showed resistance to E. coli (58.3%), Staphylococcus (75%), & Klebsiella (36.4%) and amikacin showed resistance mostly to E. coli(50%), Klebsiella (54.5%) & Pseudomonas (42.9%). Conclusion: In our study, we found the most common MDR pathogen among patients with UTI in our institution was E. coli & Staphylococcus. We discovered that being above 40 years old, having DM, CKD and previously received antibiotic medication inappropriately were risk factors for the development of MDR infection. Given the high prevalence of multidrug resistant uropathogens among immunocompromised patients, the growth in Penicillin resistance is alarming. We discovered the significant incidence of MDR bacterial strains, adherence to currently suggested empiric therapy is extremely challenging and is linked with high failure rates.

Resultados. Cuando el incremento del índice de masa corporal fue de 5 kg/m2, el promedio de infección de las vías urinarias correspondió a 1,62 y, si el incremento del índice de masa corporal fue 10 kg/m2, el promedio de infección de las vías urinarias fue 2,3. Conclusión. En nuestro estudio, a mayor incremento del índice de masa corporal durante el embarazo de la primigesta, mayor fue su probabilidad de presentar infección de las vías urinarias.

Introduction: The nutritional status of women before and during pregnancy is one of the determinants of the risk of maternal morbidity and mortality. Objective: To determine the relationship between the increase in body mass index and the presence of urinary tract infection in primigravidae. Methods: Case-control study in primigravidae records. We studied sociodemographic variables (age, schooling, life as a couple and occupation), obstetric conditions (obstetric risk, weeks of beginning of prenatal control, weeks of pregnancy resolution and number of prenatal visits), anthropometry at the beginning and end of pregnancy (weight, height, body mass index and nutritional condition -underweight, normal weight, overweight and obesity-, weight gain and body mass index gain), and modification of nutritional condition at the beginning and end of pregnancy. Statistical analysis was performed with percentages, averages, confidence intervals for averages, Chi2 test, odds ratio, confidence intervals for odds ratio, simple linear regression, and projection of event occurrence. Results: When the increase in body mass index was 5 kg/m2, the mean urinary tract infection corresponded to 1.62 and, if the increase in body mass index was 10 kg/m2, the mean urinary tract infection was 2.3. Conclusion: In our study, the greater the increase in body mass index during pregnancy of the primigravida, the greater her probability of presenting urinary tract infection.

Antimicrobial Resistance, Phenotypic Characteristics, and Biofilm Production in Citrobacter freundii Isolates Obtained from Urinary Tract Infections

Objective To evaluate the link between phenotypic traits, antimicrobial resistance, and biofilm-producing capacity of urinary isolates of Citrobacter freundii (C. Freundii). Methods Both pan-antibiotic-susceptible and -resistant C. freundii isolates (n = 120) obtained from laboratory-confirmed urinary tract infections were analyzed for their link between antimicrobial resistance, phenotypic characteristics, and biofilm production. Results Of the total C. freundii isolates (n = 120), 30% (37/120) of them formed large colonies. Among the total large colonies produced (n = 37), they were present in 21.62%, 10.81%, 13.5%, 16.2%, 21.62%, and 16.21% in the control group, CIP-group, FOS-group, COT-group, Gent-group, and ESBL groups, respectively. Compared to the pan-susceptible isolates, the occurrence of large-sized-colony-forming strains was relatively reduced in most of the drug-resistant groups. The overall distribution of mucoid colonies produced (n = 54) includes 9.25%, 18.51%, 16.66%, 18.51%, 20.3%, and 16.66% in the control group, CIP-group, FOS-group, COT-group, Gent-group, and ESBL groups, respectively. Of the total isolates that produced biofilm (n = 51), 11.76% of isolates showed biofilm formation in the control group. Alternatively, the rate was found to be 15.68%, 11.76%, 25.49%, 19.6%, and 15.68% in the CIP-group, FOS-group, SXT-group, Gen-group, and ESBL-groups, respectively. Conclusion This study correlates the association between phenotypic characteristics, antimicrobial resistance, and biofilm production, the three main characteristics of C. Freundii.

Appraising epidemiology data and antimicrobial resistance of urinary tract infections in critically ill adult patients: a 7-year retrospective study in a referral Brazilian hospital

ABSTRACT BACKGROUND: Urinary tract infections (UTI) are highly preventable and have significant clinical and financial impact on the patient and the health care system. OBJECTIVE: To investigate UTIs in critically ill adult patients and the relationship of antimicrobial consumption and multidrug-resistant isolate. DESIGN AND SETTING: A cohort study performed in a Brazilian tertiary-care university hospital in the city of Uberlandia (MG), located at the Federal University of Uberlandia, southeast region of the country. METHODS: We analyzed a cohort of 363 patients with first episode of UTIs from the adult intensive care unit (ICU), from January 2012 to December 2018. The daily doses of antimicrobial administered were calculated. RESULTS: The incidence rate of UTI was 7.2/1000 patient days, with 3.5/1000 patient-days of bacteriuria, and 2.1/1000 patient-days of candiduria. Of 373 microorganisms identified, 69 (18.4%) were Gram-positive cocci, 190 (50.9%) Gram-negative bacilli, and 114 yeasts (30.7%). Escherichia coli and Candida spp. were the most common. Patients with candiduria had higher comorbidity score (Charlson Comorbidity Index ≥ 3), longer length of stay (P = 0.0066), higher mortality (P = < 0.0001) severe sepsis, septic shock, and were immunocompromised when compared with patients with bacteriuria. We observed correlation between antibiotics consumption and multidrug-resistant (MDR) microorganisms. CONCLUSION: The UTIs incidence was high and was mainly caused by Gram-negative bacteria that were resistant to common antibiotics. We observed increase in the consumption of broad-spectrum antibiotics in ICU correlating with MDR microorganisms. In general, ICU-acquired candiduria may be associated with critical illness and poor prognosis.

Analysis of the influencing factors of urinary tract infection in pregnant women with diabetes and the distribution characteristics of pathogens in the middle urinary tract / 中国医师杂志

Objective:To investigate the influencing factors of urinary tract infection in pregnant women with diabetes and the distribution characteristics of pathogens in the middle urinary tract.Methods:A total of 220 patients with gestational diabetes who visited the Second People′s Hospital of Lianyungang City from December 2018 to December 2021 were selected as the study subjects, and the incidence of urinary tract infection was counted. According to the diagnosis results of urinary tract infection, they were divided into infected group and uninfected group. The infected group took the middle urine for pathogen culture, and the resistance rate of main gram-negative bacteria to antibiotics was analyzed; Logistic regression model was used to analyze the influencing factors of urinary tract infection in pregnant women with diabetes.Results:There were 32 cases of urinary tract infection in 220 patients with gestational diabetes, and the infection rate was 14.55%(32/220). 43 strains of pathogenic bacteria were identified, mainly gram-negative bacilli [72.09%(31/43)], followed by gram-positive cocci [20.93%(9/43)] and fungi [6.98%(3/43)]. Amongthe main gram-negative bacteria, escherichia coli had a high resistance rate to ampicillin and levofloxacin, while Klebsiella pneumoniae had a high resistance rate to ampicillin and cefazolin; There were significant differences between the infected group and the non infected group in age, hospital stay, personal urinary tract infection history, pregnancy sexual life history, use of antibiotics, fasting blood sugar, serum albumin, and glycated hemoglobin (all P<0.05); Multivariate logistic regression results showed that personal history of urinary tract infection, sexual life during pregnancy, non-standard use of antibiotics, serum albumin<30 g/L, glycated hemoglobin ≥7%, and fasting blood sugar ≥8.5 mmol/L were independent risk factors for urinary tract infection in pregnant diabetes patients (all P<0.05). Conclusions:There is a high incidence of urinary tract infection in patients with gestational diabetes, and the risk factors are complex. Gram negative bacilli are the main pathogenic bacteria. Antibacterial drugs can be reasonably selected for intervention according to drug sensitivity test in clinical practice.

Expression of urine interleukin-6, signal transducer and activator of transcription 3 and heparin-binding protein in urinary tract infection and their relationship to infection prognosis / 中国医师进修杂志

Objective:To analyze the expression levels of urinary interleukin-6 (IL-6), signal transducer and activator of transcription 3 (STAT3) and heparin-binding protein (HBP) in urinary tract infection and its correlation with infection prognosis.Methods:The clinical data of 100 patients with urinary tract infection (urinary tract infection group) from January 2021 to December 2022 in the Affiliated Hospital of Jining Medical College were retrospectively analyzed. Among them, simple urinary tract infection was in 62 cases, and complex urinary tract infection was in 38 cases; after treatment, 25 cases were not cured, and 75 cases were cured. Another 50 healthy examinees were selected as the health control group. The level of urine IL-6 was detected by luminescence assay method, the level of urine STAT3 was detected by enzyme-linked immunosorbent assay method, and the level of urine HBP was detected by fluorescence immunochromatography method. The blood routine was detected by fully automated blood cell analyzer, and the blood cell count was recorded. The levels of serum C-reactive protein (CRP) and procalcitonin (PCT) were detected by radioimmunoassay. The correlation between urine IL-6, STAT3, HBP and blood routine inflammatory response markers was analyzed by Pearson method. The receiver operating characteristic (ROC) curve was used to evaluate the predictive effectiveness of urine IL-6, STAT3, HBP and blood routine inflammatory response markers in infection prognosis.Results:The urine IL-6, STAT3, HBP, and blood CRP, PCT, white blood cell count in urinary tract infection group were significantly higher than those in healthy control group: (33.19 ± 11.02) μg/L vs. (16.84 ± 3.57) μg/L, (66.77 ± 19.58) μg/L vs. (38.69 ± 11.04) μg/L, (151.98 ± 42.00) μg/L vs. (28.55 ± 9.16) μg/L, (12.57 ± 4.19) mg/L vs. (5.23 ± 1.80) mg/L, (0.58 ± 0.19) μg/L vs. (0.22 ± 0.07) μg/L and (9.86 ± 3.20) × 10 9/L vs. (6.44 ± 2.13) ×10 9/L, and there were statistical differences ( P<0.01). The urine IL-6, STAT3, HBP, and blood CRP, PCT, white blood cell count in patients with complex urinary tract infection were significantly higher than those in patients with simple urinary tract infection: (40.25 ± 10.34) μg/L vs. (28.87 ± 8.55) μg/L, (79.50 ± 17.92) μg/L vs. (58.96 ± 13.43) μg/L, (186.51 ± 35.92) μg/L vs. (130.82 ± 39.74) μg/L, (14.09 ± 4.18) mg/L vs. (11.64 ± 3.55) mg/L, (0.64 ± 0.20) μg/L vs. (0.55 ± 0.13) μg/L and (11.27 ± 3.08) × 10 9/L vs. (8.99 ± 2.36) × 10 9/L, and there were statistical differences ( P<0.01). The urine IL-6, STAT3, HBP, and blood CRP, PCT, white blood cell count in patients with untreated urinary tract infection were significantly higher than those in patients with cured urinary tract infection: (42.97 ± 11.51) μg/L vs. (29.93 ± 8.66) μg/L, (86.81 ± 20.35) μg/L vs. (60.09 ± 17.43) μg/L, (264.27 ± 28.76) μg/L vs. (114.55 ± 21.38) μg/L, (19.11 ± 3.28) mg/L vs. (10.39 ± 2.40) mg/L, (0.85 ± 0.14) μg/L vs. (0.49 ± 0.11) μg/L and (12.26 ± 2.77) × 10 9/L vs. (9.06 ± 2.34) ×10 9/L, and there were statistical differences ( P<0.01). Pearson correlation analysis result showed that urine IL-6, STAT3, HBP were positively correlated with blood CRP, PCT, white blood cell count ( P<0.01). The ROC curve analysis result showed that the area under curve (AUC) of urine IL-6, STAT3 and HBP in predicting the infection prognosis in patients with urinary tract infection was greater than that of blood CRP, PCT and white blood cell count; moreover, the AUC and sensitivity of the combined of urine IL-6, STAT3 and HBP in predicting the infection prognosis in patients with urinary tract infection were significantly higher than the combined of blood CRP, PCT and white blood cell count (0.937 vs. 0.898 and 96.00% vs. 76.00%), but with lower specificity (81.33% vs. 98.67%). Conclusions:Urinary tract infections can cause elevated urine IL-6, STAT3 and HBP, and the degree of elevation is related to the types of simple or complicated infection and the infection prognosis. The combined detection of the urine IL-6, STAT3 and HBP is expected to be a method to predict the infection prognosis, and it provides reference information for clinical diagnosis and treatment.

Clinical characteristics and risk factors of acute focal bacterial nephritis in children / 中华肾脏病杂志

Objective:To summarize and analyze the clinical features and risk factors of acute focal bacterial nephritis (AFBN) in children.Methods:It was a retrospective cohort study. The clinical data of patients diagnosed with upper urinary tract infection in Children's Hospital Affiliated to Capital Institute of Pediatrics from July 1, 2016 to July 31, 2021 were collected, and the patients all received abdominal enhanced CT examination. According to the imaging examination results, the patients were divided into AFBN group and acute pyelonephritis (APN) group, and the clinical manifestations, laboratory and imaging examination between the two groups were compared. Logistic regression model and receiver operating characteristic curve were used to analyze the risk factors of AFBN.Results:A total of 135 patients with upper urinary tract infection were enrolled in this study, with age of 2.5 (0.5, 3.7) years old, and 68 males (50.4%). There were 67 patients (49.6%) in AFBN group and 68 patients (50.4%) in APN group. There were statistically significant differences in the highest fever temperature, duration of fever after treatment, proportion of lower urinary tract irritation symptoms, proportion of urinary tract malformation or abnormality, white blood cell count, neutrophil count, procalcitonin, C-reactive protein, proportion of pyuria, urinary β2 microglobulin and proportion of using carbapenem antibiotics between the two groups (all P<0.05). Multivariate logistic regression analysis result showed that urinary tract malformation/abnormality ( OR=3.34, 95% CI 1.23-9.10) and leukocytosis ( OR=1.25, 95% CI 1.03-1.51) were the independent risk factors of AFBN. Conclusions:The children with urinary tract infection who have high peak fever, long duration, obvious increase of inflammatory indexes and urinary β2 microglobulin may suggest AFBN. Urinary tract malformation/abnormality and high white blood cells are risk factors of AFBN.

Objective:To evaluate the clinical value of nanopore targeted sequencing (NTS) in pathogens detection in urinary tract by comparing the results of different tests performed on the same urine sample.Methods:The results of NTS and urine culture test collected from 326 patients in the Department of Urology of People's Hospital of Wuhan University from July 2020 to June 2021 were retrospectively analyzed. There were 224 males and 102 females. The average age was (56.88 ± 14.58)years old. χ 2 test and Student’s test and Wilcoxon's sign rank test were used to analyze the differences of the pathogen detection rate, pathogen types results and detection time consuming between NTS and urine culture. The clinical value of the NTS in rapid detection of urinary pathogens was evaluated. Results:Among 326 hospitalized patients, the urinary tract microbes’ detecting rate of NTS was significantly higher than that of urine culture[67.80%(221/326)vs. 23.93%(78/326), χ2=130.25, P<0.01]. The uropathogens detecting rate of NTS was significantly higher than that of urine culture[54.29%(177/326)vs. 23.31%(76/326), χ2=38.95, P<0.01]. The number of urinary tract microbes detected by NTS was significantly higher than that of urine culture ( Z=11.49, P<0.01), the number of uropathogens was significantly higher than that of urine culture ( Z=9.67, P<0.01). The detection time of NTS and urine culture positive samples was (24.29±2.65) h and (49.28±11.30) h, the difference was statistically significant ( t =39.48, P<0.01). The results obtained by using NTS and urine culture were consistent in 135 (41.41%) samples. In 150 (46.01%) samples, NTS could detect the urinary tract microbes while urine culture cannot find, of which 112 cases (34.36%) were uropathogenic. In 27 cases (8.28%), more pathogens were detected by NTS except those from urine culture. In 6 cases (1.84%) re-detecting NTS after antibiotic therapy, the number of reads of primary uropathogen decreased gradually with the growth of colonizing bacteria or opportunistic pathogens appeared in the end. Re-examinations of urine culture could verify the results of NTS detection on admission in 5 cases (1.53%). NTS in 2 cases (0.61%) could cover the uropathogens of subsequent several urine cultures. Conclusions:NTS has the advantages of rapid, sensitive and comprehensive detection of urinary tract infection pathogens. When urine culture is not yet reported or even negative, NTS already has a certain clinical reference value and can be used as an effective supplement to urine culture, which is conducive to the comprehensive judgment of the patient's condition.

Procedimiento clínico-quirúrgico en una paciente embarazada con una derivación urológica compleja. Reporte de un caso / Clinical-surgical approach in a pregnant patient with complex urological diversion. A case report

Resumen ANTECEDENTES: El mielomeningocele es el defecto del tubo neural más frecuente; se registra un caso por cada 1000 nacidos vivos. Es más frecuente en mujeres, que resultan con secuelas discapacitantes, entre ellas las urológicas. Pueden subsanarse con diferentes técnicas quirúrgicas y derivaciones urológicas complejas que las predispone a infecciones de vías urinarias de repetición y, cuando hay embarazo, complicaciones materno-fetales y dificultad para el acceso quirúrgico, en caso de cesárea. CASO CLÍNICO: Paciente con 14 semanas de embarazo, 27 años de edad, con diagnóstico de mielomeningocele y vesicoplastia, con múltiples infecciones urinarias y ruptura de membranas pretérmino. Finalización del embarazo por cesárea a las 33 semanas, por indicación de las condiciones fetales. La técnica de la cesárea se modificó para no dañar la cistoplastia y evitar complicaciones con las adherencias en la pelvis. CONCLUSIONES: El mejor pronóstico materno-fetal en pacientes con derivación urológica compleja se consigue con la búsqueda intencionada de infecciones urinarias y tratamiento oportuno y adecuado, además de una planificación multidisciplinaria al momento de la finalización del embarazo.

Abstract BACKGROUND: Myelomeningocele is the most common neural tube defect; one case per 1000 live births is reported. It is more frequent in females, resulting in disabling sequelae, including urological sequelae. They can be corrected with different surgical techniques and complex urological derivations that predispose them to repeated urinary tract infections and, when there is pregnancy, maternal-fetal complications and difficulty for surgical access, in case of cesarean section. CLINICAL CASE: Patient 14 weeks pregnant, 27 years old, diagnosed with myelomeningocele and vesicoplasty, with multiple urinary tract infections and preterm rupture of membranes. Termination of pregnancy by cesarean section at 33 weeks, due to fetal conditions. The cesarean section technique was modified so as not to damage the cystoplasty and to avoid complications with adhesions in the pelvis. CONCLUSIONS: The best maternal-fetal prognosis in patients with complex urologic diversion is achieved with the intentional search for urinary tract infections and timely and adequate treatment, in addition to multidisciplinary planning at the time of termination of pregnancy.

Profile of uropathogens in pregnancy over 5 years from a large tertiary center in South India

Objectives: Urinary tract infections (UTIs) are a common medical problem in both antenatal and postnatal women. Data from India on the demography of these women, microbiology and antimicrobial susceptibility of the causative bacteria, need elucidation. Material and Methods: We performed an observation study that collected data on UTI in antenatal and postnatal women between 2013 and 2017 at our tertiary care center in South India. Antenatally, urine dipstick-positive patients, high-risk, and symptomatic patients submitted urine cultures. Postnatally, all symptomatic patients had urine cultures. This was 20% of all antenatal and postnatal women resulting in 20,203 cultures. Results: Of 20,203 cultures, significant bacteriuria was seen in 9.48% of antenatal and 13.28% of postnatal women. A higher mean age was seen among those with UTI, antenatal 27 (SD 3.5) and postnatal 26.4 (SD 4.7) years versus 23.9 (SD 3.6) with no growth in culture. The mean BMI among antenatal was 28.2 (SD 3.5) and postnatal was 28 (SD 7.4). Most (60%) were primigravida. At delivery, 37% required cesarean sections while 21.2% required instrumental delivery. Recurrent UTI was seen in 25% antenatally and 10% in the postnatal period. Escherichia coli accounted for 66 and 60% of infections among antenatal and postnatal women, respectively. Enterococcus species accounted for 13% in both while Klebsiella species was 4.9 and 7.3%, respectively. Among E. coli, 68.3 and 59.2% of isolates in antenatal and postnatal period were cefpodoxime susceptible. Nearly 75% of ante- and postnatal isolates were susceptible to amoxicillin-clavulanate while 90.2% and 92.5% were susceptible to nitrofurantoin. Enterococci spp. up to 84.4 and 97.1% in ante- and postnatal isolates were susceptible to ampicillin, 64.4 and 77.4% susceptible to high-level gentamicin, and 84 and 95.5% susceptible to nitrofurantoin. Asymptomatic bacteriuria in pregnancy was documented in 2.1% of antenatal outpatients and E. coli was isolated in 74% of these cultures. Conclusion: Importance of microbiological evidence prior to administration of antimicrobials is evidenced by 79% negative cultures in this 5-year cohort. Escherichia coli accounted for 60-66% of significant bacteriuria followed by Enterococcus and Klebsiella species with 30-40% E.coli probable ESBL producers. Nitrofurantoin followed by amoxicillin-clavulanate were found to be the best oral antimicrobial options.

STUDY OF BACTERIURIA AMONG PREGNANT WOMEN ATTENDING A TERTIARY CARE HOSPITAL IN PANIPAT DISTRICT, INDIA

Most common population at risk for both symptomatic urinary tract infection (UTI) and asymptomatic bacteriuria, however, is sexually active women. Although asymptomatic infection in this group does not clearly produce serious medical problems, it may be a predictor of future symptomatic infection. Women are more susceptible to infection than men because of the shorter length of the female urethra. Perineal bacterial microbiota that originate in the gastrointestinal tract are the usual pathogens, especially if the bacteria possess factors that facilitate their binding to the uroepithelium. Sexual intercourse facilitates entry of the bacteria into the female urethra. Pregnant women are extra at risk of expand UTIs due to physiological adjustments withinside the urinary tract. UTI constitute severe threats to human health worldwide and hundreds of thousands of the humans affected every year. The aim of this study was to know the prevalence and antimicrobial susceptibility pattern of isolates in pregnant female patients. A total two hundred pregnant and non-pregnant females patients had been included on this study after obtaining the consent. Under strict aseptic precautions midstream urine samples had been taken from all sufferers. All the samples had been processed with the aid of using the usage of standard bacteriological methods i.e. wet mount, inoculation on blood agar and MacConkey's agar after which diagnosed with the aid of using standard biochemical tests, antibiotic sensitivity trying out changed into completed with the aid of using Kirby Bauer's disc diffusion method. In this study 80 out of 200 females patient i.e. 40% were showed UTI of which a most of 20 to 30 years age group had a considerably better occurrence of UTI i.e. 56.25%, while the age group of 60 years and above suggests the lowest contamination rate i.e 2.5% as compared to others. Females belonging to lower socioeconomic status had been extra liable to UTI then others. Pregnant females were more prone to UTI then non-pregnant females i.e. 52.73% and 35.17% respectively. Amongst pregnant females, primigravida and those in the first and second trimesters had been at higher risk. All isolates had been sensitivity to ampicillin+sulbactam, sparfloxacin, and gatifloxacin. Our study mentioned that the prevalence of UTIs was 40%; the pregnant female patients were more prone to UTI than non-pregnant females. The most isolated microorganism had been Escherichia coli which was maximum accountable for UTIs. The sexually active age group 26-30 years was highly at risk of UTI. Females belonging to lower socioeconomic status had been extra liable to contamination. Pregnancy was one in each of the predisposing elements for UTI. All isolates had been confirmed sensitivity to ampicillin+sulbactam, sparfloxacin, and gatifloxacin.

The aetiology and prevalence of urinary tract infections in Sub-Saharan Africa: a Systematic Review / Etiologia e prevalência de infecções do trato urinário na África Subsaariana: uma revisão sistemática

Objective: This review determined and reports the prevalence of urinary tract infections and aetiological agents common in most sub-Saharan African countries. Methods: A literature search involved Springer, Hindawi, PubMed, Medcrave, Google Scholar, BioMed, and Elsevier databases to identify the urinary tract infection articles published between 2000 and 2021. Results: Of 111 articles obtained from databases, 22 met the qualities to be included in the study. Overall, the prevalence of UTI was 32.12% with Escherichia coli being the most commonly isolated bacteria accounting for 86.4%. Escherichia coli is found in the GIT thus, the proximity between the anus and urinary system makes the contamination easier. Conclusion: The findings of this study provide useful information for the effective intervention of urinary tract infections. Further, it is advised women wipe from front to back whenever they attend the call of nature and or during bathing.

Objetivo: Relatamos a prevalência de infecções do trato urinário e agentes etiológicos comuns na maioria dos países da África Subsaariana. Metodos: Uma pesquisa bibliográfica envolveu as bases de dados Springer, Hindawi, PubMed, Medcrave, Google Scholar, BioMed e Elsevier para identificar os artigos que abordavam infecção do trato urinário nos países da África Subsaariana, publicados entre 2000 e 2021. Resultados: Dos 111 artigos obtidos nas bases de dados, 22 atenderam aos criterios de inclusao e foram incluídos no estudo . No geral, a prevalência de UTI foi de 32,12%, sendo a Escherichia coli a bactéria mais comumente isolada, representando 86,4%. A Escherichia coli é encontrada no TGI, portanto, a proximidade entre o ânus e o sistema urinário facilita a contaminação. Conclusao: Os achados deste estudo fornecem informações úteis para a intervenção efetiva das infecções do trato urinário. Além disso, é aconselhável que as mulheres busquem fazer sua higiene intima sempre da parte da frente para trás.

Infección de vías urinarias a trichosporon asahii. A propósito de 2 casos / Urinary tract infection to trichosporon asahii. About 2 cases

Introducción: Las infecciones de las vías urinarias constituyen una de las patologías infecciosas más frecuentes tanto en la comunidad como en el ámbito hospitalario En el medio hospitalario se ha observado una alta frecuencia de infecciones asociadas a hongos oportunistas, en su mayoría corresponden a especies de Candida spp. Sin embargo, se aíslan otras especies como Trichosporon, donde predomina la especie asahii, en casos de pacientes inmunodeprimidos o con tratamiento previo de antibioticoterapia. Presentación de Casos Clínicos: Se presentan 2 casos donde se aisló en urocultivos Trichosporon asahii. En ambos casos los pacientes presentaron factores de riesgo y síntomas inespecíficos. Conclusión: La presencia de hongos de forma persistente en el tracto urinario es considerada clínicamente significativa. El tratamiento de la funguria debe basarse en el análisis del paciente, de su estado general y de sus factores de riesgo. Para el tratamiento, se observó que el efecto de los triazoles, fueron los más efectivos en el tratamiento de la infección por T. asahii.

Introduction: Urinary tract infections are one of the most frequent infectious pathologies both in the community and in the hospital setting. In the hospital environment, a high frequency of infections associated with opportunistic fungi has been observed, most of which correspond to species of Candida spp. However, other species such as Trichosporon are isolated, where the asahii species predominates (6,7). Presentation of Clinical Cases: Two cases are presented where Trichosporon asahii was isolated in urine cultures. In both cases, the patients presented risk factors and nonspecific symptoms. Conclusion: The persistent presence of fungi in the urinary tract is considered clinically significant (9,10). The treatment of funguria should be based on the analysis of the patient, his general condition and his risk factors (10). For treatment, it was observed that the effect of triazoles was the most effective in the treatment of T. asahii infection (8)

Guía para el diagnóstico, estudio y tratamiento de la infección urinaria: actualización 2022 / Clinical practice guideline for the diagnosis and management of urinary tract infections: 2022 update

En 2015 se publicaron en Archivos Argentinos de Pediatría las "Nuevas recomendaciones frente a las actuales controversias en infección urinaria". Dado que en estos años surgieron evidencias con respecto al diagnóstico, la forma de estudio y el tratamiento de la infección urinaria, el Comité de Nefrología Pediátrica de la Sociedad Argentina de Pediatría decidió actualizar dichas recomendaciones. El objetivo principal es brindar al pediatra las herramientas para realizar un correcto diagnóstico, definir el tratamiento más adecuado, seleccionar a los pacientes que se beneficiarán con la profilaxis antibiótica y decidir cuáles serán los estudios de imágenes necesarios, para evitar intervenciones costosas e invasivas. En estas guías se incluyen, además, los lineamientos para el manejo de niños con infecciones urinarias asociadas a situaciones especiales como la disfunción vesicointestinal, el recién nacido, los portadores de vejiga neurogénica, los receptores de trasplante renal y las infecciones urinarias micóticas.

In 2015, the "New recommendations regarding the current controversies in urinary infection" were published in the Archivos Argentinos de Pediatría. Given the fact that in these past years, new evidence has emerged regarding the diagnosis and treatment of urinary infection, the Pediatric Nephrology Committee of Sociedad Argentina de Pediatría has decided to update these recommendations. The main goal is to provide the pediatrician with the necessary tools to make a correct diagnosis, define the most appropriate treatment, select the patients who will benefit from antibiotic prophylaxis, and decide which imaging studies will be necessary, avoiding costly and invasive interventions. These guidelines also include the management of children with urinary tract infections associated with special situations such as: bladder bowel dysfunction, the newborn, children with neurogenic bladder, kidney transplant patients and fungal urinary tract infections.

Emphysematous pyelonephritis caused by C. glabrata / Pielonefrite enfisematosa por C. glabrata

Abstract Emphysematous pyelonephritis (EPN) is a rare acute necrotizing infection of the kidney and surrounding tissues, with gas in the renal parenchyma, collecting system or perirenal tissue. The bacterial etiology predominates; mainly Gram-negative bacilli; Candida spp. and C. albicans are rarely described. We describe a case of EPN caused by C. glabrata, sensitive to fluconazole in a young, hypertensive woman with undiagnosed diabetes mellitus (DM), with renal dysfunction upon admission; her abdominal CT scan found a volumetric increase in the left kidney, signs of gas collections and perirenal blurring. Despite the antimicrobial therapy instituted, due to clinical refractoriness, a double J catheter and subsequent total nephrectomy were indicated, with good postoperative evolution. Her uroculture showed C. glabrata sensitive to fluconazole, and the pathology study showed tubular atrophy and intense interstitial inflammatory infiltrate. Despite the serious, potentially fatal condition, we could control the infection and the patient recovered fully. Poor DM management is an important triggering factor, and it is of great relevance to identify the EPN through imaging exams due to the peculiarities of its clinical and potentially surgical management

Resumo A pielonefrite enfisematosa (PNE) é uma infecção aguda rara necrotizante do rim e dos tecidos adjacentes, com presença de gás no parênquima renal, sistema coletor ou tecido perirrenal. Predomina a etiologia bacteriana, principalmente bacilos Gram-negativos; Candida spp. e na maioria das vezes C. albicans são raramente descritas. Descreve-se um caso de PNE causada por C. glabrata sensível a fluconazol em mulher jovem, hipertensa e com diabetes mellitus (DM) não diagnosticada, com disfunção renal à admissão; tomografia computadorizada de abdome constatou aumento volumétrico do rim esquerdo, sinais de coleções gasosas e borramento perirrenal. Apesar da terapia antimicrobiana instituída, devido à refratariedade clínica, foi indicado cateter duplo J e posterior nefrectomia total, com boa evolução pós-operatória. A urocultura evidenciou C. glabrata sensível a fluconazol, e o anatomopatológico demonstrou atrofia tubular e intenso infiltrado inflamatório intersticial. Apesar da condição grave, potencialmente fatal, houve controle do foco infeccioso e plena recuperação da paciente. O mau manejo do DM é um importante fator desencadeante, e é de grande relevância identificar a PNE por meio de exames de imagem devido às peculiaridades de seu manejo clínico e potencialmente cirúrgico.
