Gene of the month: the uroplakins.

Uroplakins are a family of membrane-spanning proteins highly specific to the urothelium. There are four uroplakin proteins in humans. These are encoded by the following UPK genes: UPK1A, UPK1B, UPK2 and UPK3 Uroplakin proteins span the apical membrane of umbrella cells of the urothelium, where they associate into urothelial plaques. This provides a barrier function to prevent passage of urine across the urothelium in the renal pelvis, ureters, and bladder. Uroplakins are also involved in developmental processes such as nephrogenesis. The specific localisation of uroplakins within the urothelium means that they are often expressed in primary and metastatic urothelial cell carcinoma and may be used as an immunohistochemical marker of urothelial malignancy.

Macroscopy of specimens from the genitourinary system.

Macroscopic specimen examination is often critical for accurate histopathology reporting but has generally received insufficient attention and may be delegated to inexperienced staff with limited guidance and supervision. This review discusses issues around macroscopic examination of some common urological specimens; highlighting findings that are critical for patient management and others that are clinically irrelevant. Macroscopic findings are of limited value in completely submitted radical prostatectomy specimens but may be critical in orchidectomy specimens where identification of focal non-seminomatous components can significantly impact patient management. The maximum tumour dimension is often an important prognostic indicator, but specimen dimensions are generally of little clinical utility. Specimens should be carefully examined and judiciously sampled to identify clinically important focal abnormalities such as sarcomatoid change in a renal cell carcinoma and a minor non-seminomatous component in a predominant testicular seminoma. Meticulous macroscopic examination is key as less than 0.2% of the specimen (or macroscopically abnormal area) would be histologically examined even if the entire specimen/abnormal area is submitted for microscopic examination. Retroperitoneal pelvic lymph node dissection specimens for testicular cancer must be handled very differently from other lymph nodal block dissections. Current sampling protocols for transurethral resection of prostate specimens that are based on pre-MRI era data need to be reconsidered because they were specifically designed to detect occult prostate cancer, which would amount to histological cancer screening. Prostatic sampling of cystoprostatectomy specimens should be directed at accurately staging the known bladder cancer rather than detection of incidental prostate cancer.

Differences in clinical features between focal and extensive types of cystitis glandularis in patients without a previous history of urinary tract malignancy.

PURPOSE: To understand the clinical differences of cystitis glandularis (CG), a proliferative disorder of urinary bladder epithelium, based on the extent of cystoscopic findings in patients without a history of urinary tract malignancy. MATERIALS AND METHODS: We conducted a review of patients diagnosed with CG in two tertiary hospitals from 2005 to 2021. Patients with previous or concurrent history of urinary tract malignancy were excluded. Medical records, including demographics, endoscopic and all available imaging studies, and managements, were reviewed. Patients were divided into two types according to extent of the lesion, and their clinical features were compared. RESULTS: In total, 110 patients were enrolled in the final analysis, with 36 (32.7%) classified as extensive type and 74 (67.3%) as focal type. Patients with extensive type were predominantly males and relatively younger than those with focal type (p=0.025). Voiding problems were more strongly associated and hydronephrosis caused by CG was significantly more common in the extensive type (p=0.005 and p=0.003, respectively). Multiple transurethral resection procedures were more frequently performed in the extensive type (p=0.017). Subsequent urinary tract malignancy was observed in four patients, all of whom had focal-type CG. CONCLUSIONS: There were significant differences in clinical features between the extensive- and focal-types CG. The extensive type was more often associated with urologic complications. Meanwhile, in the focal type, subsequent urinary tract malignancy might develop during the follow-up period. Thus, thorough initial work-up and careful follow-up is necessary despite the benign nature of CG. Annual surveillance cystoscopy may be appropriate.

Physiotherapeutic assessment and management of overactive bladder syndrome: a case report.

INTRODUCTION: Overactive Bladder Syndrome (OAB) has multiple treatment methods including pharmacotherapy, pelvic floor muscle training, electrostimulation, or surgery. One of the nonpharmacological treatment options is physiotherapy including pelvic floor muscle training. CASE DESCRIPTION: The patient was a 25 year-old woman who attended the urogynecological physiotherapy consulting room due to frequent sensations of bladder pressure. Manual inspection and ultrasound imaging was used by the physiotherapist in order to assess the function of pelvic and abominal structures. The patient reported pain symptoms during examination of several pelvic floor and abdominal muscles. The patient was judged eligible for urogynecological physiotherapeutic treatment. Manual therapy of the lumbopelvic hip complex, manual therapy per vaginum, manual therapy of the musculus piriformis, and therapy of the superficial back line myofascial meridian and the lateral line myofascial meridian were used. During the final session, the patient reported an improvement in relation to the symptoms presented, most notably no frequent feeling of bladder pressure. CONCLUSIONS: Treatment of OAB is often a multistage process involving application of different therapies by a multidisciplinary team. For this patient, physiotherapy assessment and intervention were an integral part of the conservative management of OAB.

Urological, vascular, and infectious implications of kidney transplant: a single-center experience / Complicaciones urológicas, vasculares e infecciosas del trasplante renal: experiencia en un solo centro

Introduction: Kidney transplant has improved in the last decades due to new technologies and surgical techniques. However, there are still multiple complications associated with this procedure, which can affect the function and viability of the kidney graft. Our aim was to describe the incidence of urological, vascular, and infectious complications in the 1st month after the procedure. Methods: A cross-sectional and retrospective study was carried out. Records of all patients who underwent kidney transplant from 2007 to 2017 were reviewed and data of demographic and surgical variables as well as information of vascular, urological, and infectious complications during the 1st post-operative month were registered and analyzed. Results: A total of 243 patients that required kidney transplant were assessed. The most common chronic kidney disease etiologies were: idiopathic (25.5%), glomerulopathies (24.7%), and hypertension (23.5%). Seventy patients (28.8%) presented a complication, of which 31 were urological, 27 were infectious, and 12 were vascular. In each category, the most frequent complications were the perirenal hematoma, the urinary tract infection, and renal artery stenosis, respectively. Conclusions: The prevalence of complications found in our center is similar to that reported in the literature and it is significant. It is important for medical personnel to be aware of this data to have a high level of suspicion and make an active search, as an early diagnosis and treatment of these pathologies are crucial to avoid graft loss

Nuestro objetivo fue describir la incidencia de complicaciones urológicas, vasculares e infecciosas en el primer mes tras el procedimiento. Métodos: Se realizó un estudio retrospectivo de corte transversal. Se revisaron los expedientes de todos los pacientes que se sometieron a trasplante renal desde 2007 hasta 2017 y se registraron y analizaron datos de variables demográficas y quirúrgicas, así como información de complicaciones vasculares, urológicas e infecciosas durante el primer mes postoperatorio. Resultados: Se evaluaron un total de 243 pacientes que requirieron trasplante renal. Las etiologías de enfermedad renal crónica (ERC) más frecuentes fueron: idiopática (25,5%), glomerulopatías (24,7%) e hipertensión arterial (23,5%). 70 pacientes (28,8%) presentaron alguna complicación, de los cuales 31 fueron urológicos, 27 infecciosos y 12 vasculares. En cada categoría las complicaciones más frecuentes fueron el hematoma perirrenal, la infección del tracto urinario y la estenosis de la arteria renal respectivamente. Conclusiones: La prevalencia de complicaciones encontrada en nuestro centro es similar a la reportada en la literatura y es significativa. Es importante que el personal médico conozca estos datos para tener un alto nivel de sospecha y realizar una búsqueda activa, ya que el diagnóstico y tratamiento precoz de estas patologías es fundamental para evitar la pérdida del injerto.

Analysis of stone composition and clinical characteristics of urinary calculi in infants in Xinjiang / 国际外科学杂志

Objective:To analyze the composition and clinical characteristics of urinary calculi in infants in Xinjiang.Methods:The clinical data of 75 infants with urinary calculi admitted to the People′s Hospital of Xinjiang Uygur Autonomous Region from January 2016 to December 2021 were retrospectively analyzed, including the general situation of the children, stone-related parameters, random urine pH value, urine culture and biochemical examination results. The serum uric acid, serum calcium, urine pH value, positive rate of urine culture, and stone length between infants with and without ammonium urate stones were compared. Measurement data conforming to normal distribution were expressed as mean ± standard deviation ( ± s), and independent sample t-test was used for inter-group comparison. Measurement data that did not conform to the normal distribution were expressed as the median (interquartile distance) [ M ( Q1, Q3)], and Mann-Whitney U test was used for comparison between groups. The Chi-square test, continuity-corrected Chi-square test or Fisher exact probability method were used for the comparison of count data. Results:The median age of infants with urinary calculi was 23.04 months, and the ratio of male to female was 3.2∶1. More than half of the infants (81.3%, 61/75) came from rural areas, 57.3% (43/75) were malnourished, 33.3% (25/75) were complicated with urinary tract infection, and 8.0% (6/75) were combined with urinary system congenital malformation. The calculi were found in 53 cases (70.67%) of kidney, 27 cases (36.0%) of ureter, 17 cases (22.67%) of urethra and 16 cases (21.33%) of bladder. The analysis of calculi composition showed that there were 44 cases (58.67%) of ammonium urate, 39 cases (52.0%) of calcium oxalate, 14 cases (18.67%) of apatite carbonate and 7 cases (9.33%) of uric acid. Kidney calculi was more common in female infants ( P=0.011). Compared with the infant group ( n=19), calcium oxalate stones were more common in the preschooler group ( n=56) ( P=0.039), but there were not statistical difference in the incidence of ammonium urate, apatite carbonate and uric acid stones. There were not statistical difference in gender, age, place of residence, nutritional status, serum uric acid, serum calcium, urine pH value, positive rate of urine culture, stone maximum diameter and incidence of bladder stones between ammonium urate group and non-ammonium urate group. Conclusions:The incidence of urinary calculi in infants is higher in boys, and the most common site of calculi is the upper urinary tract, especially in female kidney calculi. Ammonium urate is the main component of urinary calculi in infants. Calcium oxalate stones are more common in preschooler group. Infants with urinary calculi are mostly rural residents, and malnutrition and urinary tract infection are more common.

Systematic review and meta-analysis of ketamine-associated uropathy.

INTRODUCTION: This systematic review and meta-analysis focused on the literature regarding ketamine-associated uropathy to summarise its clinical manifestations, the results of urological assessments, and current management. METHODS: A literature search was conducted using keywords and MeSH terms related to ketamine abuse, urinary tracts, and urological examinations. Databases including Embase, MEDLINE, and the Cochrane Central Register of Controlled Trials were searched up to 26 June 2020. RESULTS: In total, 1365 articles were retrieved; 45 articles (4921 patients) were included in the analysis of patient demographics, clinical manifestations, examination results, and treatments. Frequency was the most common manifestation (pooled prevalence 77.1%, 95% confidence interval [CI]=56.9%-92.2%), followed by urgency (69.9%, 95% CI=48.8%-87.3%) and suprapubic pain (60.4%, 95% CI=35.3%-82.9%). Upper urinary tract involvement was less common; the pooled prevalence of hydronephrosis was 30.2% (95% CI=22.0%-39.2%). Further workup revealed a pooled functional bladder capacity of 95.23 mL (95% CI=63.57-126.88 mL), pooled voided volume of 113.31 mL (95% CI=59.44- 167.19 mL), and pooled maximum urine flow rate of 8.69 mL/s (95% CI=5.54-11.83 mL/s). Cystoscopic examinations and bladder biopsy revealed frequent urothelial denudation, inflammatory changes, and inflammatory cell infiltration. Treatments included oral medications for symptomatic relief, intravesical therapy, and surgery (eg, hydrodistension and bladder reconstruction), but ketamine abstinence was necessary for improvement. CONCLUSION: Ketamine-associated uropathy frequently involves frequency, urgency, and suprapubic pain; upper urinary tract involvement is less common. Affected patients showed reductions in bladder capacity and urine flow rate. Endoscopic and histological analyses often revealed cystitis. Despite variations in treatment, ketamine abstinence is important for all patients with ketamine-associated uropathy.

Oxidative Stress Biomarkers in Age-Related Lower Urinary Tract Disorders: A Systematic Review.

PURPOSE: To conduct a systematic review of preclinical and clinical peer-reviewed evidence linking alterations in oxidative stress biomarkers or outcome measures that were also prevalent in specific age-related lower urinary tract (LUT) disorders. METHODS: PubMed, Scopus, CINAHL, and Embase were searched for peer-reviewed studies published between January 2000 and March 2021. Animal and human studies that reported on the impact of oxidative stress in age-related LUT disorders through structural or functional changes in the LUT and changes in biomarkers were included. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol was followed. RESULTS: Of 882 articles identified, 21 studies (13 animal; 8 human) met inclusion criteria. Across LUT disorders, common structural changes were increased bladder and prostate weights, ischemic damage, nerve damage and detrusor muscle hypertrophy; common functional changes included decreased bladder contraction, increased bladder sensation and excitability, decreased perfusion, and increased inflammation. The disorders were associated with increased levels of biomarkers of oxidative stress that provided evidence of either molecular damage, protective mechanisms against oxidative stress, neural changes, or inflammation. In all cases, the effect on biomarkers and enzymes was greater in aged groups compared to younger groups. CONCLUSION: Increased oxidative stress, often associated with mitochondrial dysfunction, plays a significant role in the pathogenesis of age-related LUT disorders and may explain their increasing prevalence. This systematic review identifies potential markers of disease progression and treatment opportunities; further research is warranted to evaluate these markers and the mechanisms by which these changes may lead to age-related LUT disorders.

A 25-Year-Old Chronic Ketamine User with Urinary Symptoms; a Case Report.

Ketamine is mainly used for short-acting general anesthesia, chronic pain, sedation, depression, and bipolar disorder. Long-term ketamine use may cause lower urinary tract symptoms and voiding dysfunction. Small capacity and fibrotic bladder can be associated with chronic ketamine use. Here, we present a 25-year-old male with a history of chronic ketamine use complicated with contracted heart-shape bladder.

Inflammatory Cells in Nephrectomy Tissue from Patients without and with a History of Urinary Stone Disease.

BACKGROUND AND OBJECTIVES: Urinary stone disease has been associated with inflammation, but the specific cell interactions that mediate events remain poorly defined. This study compared calcification and inflammatory cell patterns in kidney tissue from radical nephrectomy specimens of patients without and with a history of urinary stone disease. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Nontumor parenchyma of biobanked radical nephrectomy specimens from age- and sex-matched stone formers (n=44) and nonstone formers (n=82) were compared. Calcification was detected by Yasue staining and inflammatory cell populations by immunohistochemistry for CD68 (proinflammatory M1 macrophages), CD163 and CD206 (anti-inflammatory M2 macrophages), CD3 (T lymphocytes), and tryptase (mast cells). Calcifications and inflammatory cells were quantified in cortex and medulla using Image-Pro analysis software. RESULTS: Calcification in the medulla of stone formers was higher than in nonstone formers (P<0.001). M1 macrophages in the cortex and medulla of stone formers were greater than in nonstone formers (P<0.001), and greater in stone former medulla than stone former cortex (P=0.02). There were no differences in age, sex, body mass index, tumor characteristics (size, stage, or thrombus), vascular disease status, or eGFR between the groups. M2 macrophages, T lymphocytes, and mast cells did not differ by stone former status. There was a correlation between M1 macrophages and calcification in the medulla of stone formers (rho=0.48; P=0.001) and between M2 macrophages and calcification in the medulla of nonstone formers (rho=0.35; P=0.001). T lymphocytes were correlated with calcification in the cortex of both nonstone formers (rho=0.27; P=0.01) and stone formers (rho=0.42; P=0.004), whereas mast cells and calcification were correlated only in the cortex of stone formers (rho=0.35; P=0.02). CONCLUSIONS: Higher medullary calcification stimulated accumulation of proinflammatory rather than anti-inflammatory macrophages in stone formers.

Comparison between 1973 and 2004/2016 WHO grading systems in patients with Ta urothelial carcinoma of urinary bladder.

AIMS: To compare the 1973 WHO and the 2004/2016 WHO grading systems in patients with urothelial carcinoma of urinary bladder (UCUB), since no consensus has been made which classification should supersede the other and since both are recommended in clinical practice. METHODS: Newly diagnosed patients with Ta UCUB treated with transurethral resection of bladder tumour were abstracted from the Surveillance, Epidemiology and End Results database (2010-2016). Kaplan-Meier plots and multivariable Cox regression models (CRMs) tested cancer-specific mortality (CSM), according to 1973 WHO (G1 vs G2 vs G3) and to 2004/2016 WHO (low-grade vs high-grade) grading systems. RESULTS: Of 35 986 patients, according to 1973 WHO grading system, 8165 (22.7%) were G1, 17 136 (47.6%) were G2 and 10 685 (29.7%) were G3. According to 2004/2016 WHO grading system, 24 961 (69.4%) were low-grade versus 11 025 (30.6%) high-grade. In multivariable CRMs, G3 (HR: 2.05, p<0.001), relative to G1, and high-grade(HR: 2.13, p<0.001), relative to low-grade, predicted higher CSM. Conversely, G2 (p=0.8) was not an independent predictor. The multivariable models without consideration of either grading system were 74% accurate in predicting 5-year CSM. After addition of 1973 WHO or 2004/2016 WHO grade, the accuracy increased to 76% and 77%, respectively. CONCLUSIONS: From a statistical standpoint, it appears that the 2004/2016 WHO grading system holds a small, although measurable advantage over the 1973 WHO grading system. Other considerations, such as intraobserver and interobserver variability may represent an additional matric to consider in deciding which grading system is better.

Creation of a Pilot Surgical Program for the Comprehensive Management of Patients with Congenital Urological Malformations / Creación de un programa quirúrgico piloto para el manejo integral de pacientes con malformaciones urológicas congénitas

Objectives Congenital malformations constitute the first cause of morbidity and mortality in childhood in Latin America. That is why, since 2001, a surveillance system for congenital malformations has been implemented in Bogota - Colombia. However, despite the increase in detection, an impact on treatment has not been achieved. The present study describes our experience with a novel social program focused on congenital urologic disorders. Methods The present manuscript is a retrospective observational study. We reviewed two national databases containing patients with congenital malformations. Patients were actively contacted to verify the status of the malformations. Children in whom the malformation was confirmed were offered a free consultation with a multidisciplinary group. After screening for surgical indications, patients were scheduled for surgery. Results Between November 2018 and December 2019, 60 patients were identified. In total 44, attended the consultation; the remaining did not attend due to financial or travel limitations. The most common condition assessed was hypospadias. In total, 29 patients underwent surgery. The total cost of care was of US$ 5,800. Conclusions Active search improves attention times and reduces the burden of disease. The limitations to be resolved include optimizing the transportation of patients and their families, which is a frequent limitation to access health care.

Objetivos Las malformaciones congénitas corresponden a la principal causa de morbimortalidad en la infancia en América Latina, motivo por el cual desde el 2001 se viene implementando un sistema de vigilancia epidemiológica de malformaciones congénitas en Bogotá, Colombia. Sin embargo, a pesar del aumento en la cobertura del reporte obligatorio, no se ha logrado un impacto sobre su tratamiento. Este estudio busca mostrar nuestra experiencia con un programa integral de pacientes con malformaciones urológicas congénitas. Métodos El presente es un estudio observacional retrospectivo. Los menores con malformaciones congénitas fueron identificados en dos bases de datos nacionales que incluyen pacientes con malformaciones congénitas. Los pacientes reportados fueron contactados telefónicamente para verificar el estado actual de la malformación. A aquellos niños en quienes se les confirmó la malformación, se les ofreció de manera gratuita una consulta con un grupo multidisciplinario. Una vez confirmadas las indicaciones quirúrgicas, fueron llevados a cirugía. Resultados Se identificaron 60 pacientes entre noviembre del 2018 y diciembre de 2019. De los pacientes identificados, 44 acudieron a consulta. Los demás no asistieron por limitaciones económicas. La principal condición valorada fue hipospadias. En total, 29 pacientes fueron llevados a cirugía. El costo total de la atención de estos pacientes fue de 22 millones de pesos colombianos. Conclusiones La búsqueda activa mejora los tiempos de atención y reduce la carga de la enfermedad. Una de las limitaciones aun por resolver es optimizar el transporte de los pacientes y sus familias, que resulta una limitación frecuente para el acceso a la salud.

Publication Trends in Pediatric Stone Disease: A Bibliometric Analysis / Tendencias de publicación en la litiasis pediátrica: Un análisis bibliométrico

Introduction In the pediatric population, the prevalence of stone disease has increased in recent years. We aim to analyze the bibliometric characteristic of available literature on the management of stones in this population. Methods We performed a search for articles published until December 2019 on the Scopus, Google Scholar, PubMed, Embase, and Web of Science databases using the keywords children, lithiasis, and stones. We excluded articles involving patients older than 18 years of age and those with non-urological lithiasis. Then, we performed a bibliometric analysis using the original language, year of publication, impact factor (yearly number of citations), and absolute citation count as variables to calculate the impact index (number of sources adjusted for the time since publication). Results We included 291 articles published between 1940 and December 2019 for analysis. The average number of citations per manuscript was of 15.3 (± 21.9), and the average impact index was of 502 (± 976.4). A total of 4 articles were published before 1970. The evaluation of historical landmarks that could affect citation counts, such as the launch of a journal specialized in pediatric urology (Journal of Pediatric Urology), showed a mean citation count of 23.29 before the first edition, and of 14.96 after (p = 0.0006). The variation on the impact index with the same criteria was of 539.6 before the first edition of the Journal of Pediatric Urology, and of 316.32 after (p = 0.001). The average number of citations before internet access was of 17.9, and, after the internet, of 15.1 (p = 0.17). We also observed a difference in counts regarding languages of publication. Conclusions The proportional academic productivity on pediatric stone disease demonstrates that citation counts do not reflect the true academic impact of subspecialized topics.

Introducción La prevalencia de la urolitiasis en la población pediátrica ha venido aumentando en los últimos años. Este manuscrito busca analizar las características bibliométricas de la literatura disponible sobre el manejo de la urolitiasis pediátrica. Métodos Realizamos una búsqueda por artículos publicados hasta diciembre de 2019 en las bases de datos Scopus, Google Scholar, PubMed, Embase y Web of Science con las palabras children, lithiasis, y stones. Excluimos artículos con pacientes mayores de 18 años y litiasis no urológica. Posteriormente, realizamos un análisis bibliométrico utilizando el idioma original, el año de publicación, el factor de impacto (número de citas anuales), y el recuento absoluto de citas para calcular el índice de impacto (número de fuentes ajustadas por el tiempo desde la publicación). Resultados Analizamos 291 artículos publicados desde 1940 hasta diciembre de 2019. El promedio de citas por artículo fue de 15,3 (± 21,9), y el índice de impacto fue de 502 (± 976,4). Un total de 4 artículos fueron publicados antes de 1970. La evaluación de hitos históricos que pudieran afectar el recuento de citas, como el lanzamiento de una revista de urología pediátrica (Journal of Pediatric Urology), mostró un recuento medio de citas de 23,29 antes de la primera edición, y de 14,96 después (p = 0,0006). La variación del índice de impacto con los mismos criterios fue de 539,6 antes de la primera edición de esta revista, y de 316,32 después (p = 0,001). El promedio de citas antes del acceso a la internet fue de 17,9, y después, de 15,1 (p = 0,17). Observamos también una diferencia en los recuentos respecto a los idiomas de publicación. Conclusiones La productividad académica sobre la litiasis pediátrica demuestra que los recuentos de citas no reflejan el verdadero impacto académico de los temas subespecializados.

Association between Genitourinary and Congenital Heart Defects: A 52-year Case-Control Study of the Latin American Collaborative Study of Congenital Malformations (ECLAMC) / Asociación entre cardiopatías congénitas y malformaciones congénitas urinarias: Un estudio de casos y controles de 52 años del Estudio Colaborativo Latino Americano de Malformaciones Congénit

Background Congenital urological anomalies are present in 4.3/10 thousand newborns, and their association with other anomalies may increase the overall mortality and disability. The present study establishes the risk of having congenital urological anomalies presenting associated cardiopathies. Methods We conducted a retrospective case-control study using the Latin American Collaborative Study of Congenital Malformations (Estudio Colaborativo Latino Americano de Malformaciones Congénitas, ECLAMC, in Spanish). The analysis included all registered cases of congenital urological malformation from 1967 to 2019. Patients with or without associated heart defects were included for the statistical analysis. Odds ratios (ORs) were calculated using a 95% confidence interval (95% CI). We compared the variables with the Chi-squared test and analysis of variance (ANOVA). The statistical analysis was performed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, United States) software, version 27.0. Values of p < 0.05 were considered statistically significant. Results A total of 7,767,161 newborns were evaluated, and 17,834 genital and upper urinary tract malformations were identified. Of these, 64.2% were genital anomalies, and 35.8% were abnormalities of the upper urinary tract. Genitourinary malformations and concomitant congenital heart defects (GU + C) were observed in 3.5% of the cases. Subjects with GU + C had a higher number of malformations (4.59 ± 2.3) than patients without heart defects (1.53 ± 1.58) (p < 0.000). The OR was of 3.61 (range: 1.86­7.00) for cloacal exstrophy, of 4.01 (range: 3.14­5.12) for imperforate anus, of 5.52 (range: 3.92­7.78) for horseshoe kidney, and of 13.7 (range: 6.65­28.22) for trisomy 21 (Down syndrome) with malformations of the upper urinary tract. Conclusion The association of congenital heart defects with urological anomalies is higher for complex congenital anomalies such as imperforate anus, cloacal exstrophy, and ho

Introducción Las malformaciones congénitas urológicas están presentes en 4,3/10 mil, y su asociación con otros defectos puede aumentar la mortalidad global y la discapacidad. Este estudio analiza la presentación de las malformaciones congénitas urológicas asociadas a las cardiopatías congénitas. Métodos Este es un estudio retrospectivo de casos y controles que usa el Estudio Colaborativo Latinoamericano de Malformaciones Congénitas (ECLAMC). Se incluyeron todos los casos registrados de malformaciones congénitas urológicas de 1967 a 2019, y todos los casos con y sin defectos cardiacos. Se calculó la razón de disparidad (RD) usando un intervalo de confianza del 95% (IC 95%). Se probó la hipótesis con el Chi-cuadrado y análisis de la varianza (analysis of variance, ANOVA, en inglés). Se realizó el análisis estadístico por medio del programa Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, Estados Unidos), versión 27.0. Se consideró la significancia estadística con valores de p < 0,05. Resultados Se evaluaron 7.767.161 recién nacidos, y se identificaron 17.834 malformaciones genitales y del tracto urinario superior. De estas, 64,2% fueron genitales, y 35,8%, de vías urinarias superiores. El 3,5% de los casos tenían malformaciones genitourinarias y defectos cardiacos congénitos concomitantes (GU + C). Aquellos con GU + C tenían mayor número de malformaciones (4,59 ± 2,3) que los pacientes sin defectos cardiacos (1,53 ± 1,58) (p < 0,000). La RD fue de 3.61 (rango: 1,86­700) para la extrofia cloacal, de 4,01 (3,14­5,12) para el ano imperforado, de 5,52 (3,92­7,78) para el riñón en herradura, y de 13,7 (6,65­28,22) para la trisomía 21 (síndrome de Down) con malformaciones del tracto urinario superior. Conclusión La asociación entre defectos cardiacos congénitos y anomalías urológicas es significativa en malformaciones congénitas complejas como el ano imperforado, la extrofia cloacal, y el riñón en herradura. Los pacientes con síndrome de Down y malformaciones urológicas tienen la mayor probabilidad.

Infección del tracto urinario asociada a catéter urinario a permanencia: tendencia del indicador en chile

Objetivo: Analizar la tendencia del indicador "Infección del tracto urinario asociado a instalación de catéter urinario a permanencia" en Chile. Material y Método: Estudio ecológico, de series temporales en el sistema sanitario de Chile, correspondiente a un total de 15 regiones, desde el año 2001 al año 2017 (27.087.087 casos). Se incluyeron datos cuyo egreso hospitalario era infección de tracto urinario asociado a catéter urinario a permanencia, según la Clasificación Internacional de Enfermedades (CIE 10). El análisis descriptivo y correlacional (X2 y T de Student, respectivamente) se realizó en función del sexo, tipo de previsión, condición de egreso y operación quirúrgica. El análisis se realizó con el programa SPSS 24 y el nivel de significación estadística fue p< 0,05. La estimación, basada en análisis lineal, estimó cambios porcentuales anuales (APC: Annual Percentage Change) y sus intervalos de confianza al 95%. Se empleó el método de auto-regresión de Prais Winsten. El resguardo ético siguió lo dispuesto en la Ley N° 20.585. Resultados: Se observó un 2% de crecimiento interanual (APC= 0,00007; IC: 95%= 0,000069-0,000073). En los años 2005, 2008, 2009 y 2011 existió un aumento en el porcentaje de cambio de 2 a 5 puntos. Conclusión: El indicador analizado es un evento que ha presentado una tendencia creciente y significativa en Chile desde el año 2001, lo que resulta paradójico, puesto que el ordenamiento de los procesos hospitalarios, asociado a la Reforma de Salud, debería demostrar una mejora en el comportamiento de este tipo de indicadores.

Objective: To analyze the trend indicator "Urinary tract infection associated with indwelling urinary catheter insertion" in Chile. Material and Method: Ecological, time series study, carried out in the Chilean health system, corresponding to a total of 15 administrative regions, from 2001 to 2017 (27.087.087 cases). Data included information on patients whose hospital discharge was urinary tract infection associated with indwelling urinary catheter, according to the International Classification of Diseases (ICD-10). Descriptive and correlational analysis (X2 and Student's t-test, respectively) was performed according to sex, type of health insurance, hospital discharge condition and surgical operation. The analysis was performed using SPSS 24 software and the level of statistical significance was p<0.05. The estimation was based on linear analysis, estimating annual percentage changes (APC) and their 95% confidence intervals. The Prais-Winsten autoregression method was used. Ethical considerations followed the provision of Law No. 20.585. Results: A 2% interannual growth rate was observed (APC= 0.00007; CI: 95% = 0.000069-0.000073). In the years 2005, 2008, 2009 and 2011 there was an increase in the percentage change of 2 to 5 points. Conclusion: The analyzed indicator corresponds to an event that has shown a significant and increasing trend in Chile since 2001, which seems paradoxical, since hospital processes management, associated with the health care reform, should show an improvement regarding this type of trend indicator.

Sexually transmitted infections in indigenous communities of the Alto Rio Solimões / Infecções sexualmente transmissíveis em comunidades indígenas do Alto Rio Solimões

Introduction: The prevalence of sexually transmitted infections (STI) among indigenous communities is an appalling issue related to Brazilian public health, as there is an increasing underreporting and neglect related to the study and care of these people. Objective: To determine the prevalence of STI in the indigenous population of the Alto Rio Solimões. Methods: STI diagnostic records from the database of the Indigenous Health Care Information System - SIASI, of the indigenous communities of the Alto Rio Solimões, belonging to the Nova Itália base, in Amazonas, were evaluated during the period from January 2010 to August 2020. Sociodemographic data were also evaluated to determine the profile of the diagnosed indigenous population and the geographical and temporal distribution of cases. Results: The overall prevalence rate of STIs was 3.91% (113 notifications of STI in the population of 2890 indigenous people). The largest number of diagnosed cases was in Nova Itália (60.17%). The ethnic group with the highest number of cases was Tikuna (92.03%). Among the STI studied, gonorrhea / chlamydia had the highest prevalence (68.14%), followed by Hepatitis B (13.27%) and Syphilis (10.61%). Most cases were found among women (71.7%), aged 30­34 years. Conclusion: A higher prevalence of STIs was observed in indigenous women, mainly from the Nova Itália town and the Tikuna ethnic group.

Introdução: A prevalência das infecções sexualmente transmissíveis (IST) entre comunidades indígenas é um tema consternador relacionado à saúde pública brasileira, pois há crescente subnotificação e negligência relacionada ao estudo e ao cuidado desses povos. Objetivo: Determinar a prevalência de IST na população indígena do Alto Rio Solimões. Métodos: Foram avaliados os registros diagnósticos de IST da base de dados do Sistema de Informação da Atenção à Saúde Indígena (SIASI), das comunidades indígenas do Alto Rio Solimões, pertencentes ao polo-base de Nova Itália, no Amazonas, durante o período de janeiro de 2010 a agosto de 2020. Também foram avaliados dados sociodemográficos para determinação do perfil da população indígena diagnosticada e a distribuição geográfica e temporal dos casos. Resultados: A taxa de prevalência geral de IST foi de 3,91% (113 notificações de IST na população de 2.890 indígenas). O maior número de casos diagnosticados foi em Nova Itália (60,17%). A etnia com maiores números de casos foi a Tikuna (92,03%). Entre as IST estudadas, gonorreia/clamídia tiveram a maior prevalência (68,14%), seguidas por hepatite B (13,27%) e sífilis (10,61%). A maioria dos casos ocorreu entre mulheres (71,7%) e na faixa de 30­34 anos. Conclusão: Observou-se maior prevalência de IST em mulheres indígenas, principalmente do município de Nova Itália e da etnia Tikuna

Multiparametric Prostate MRI in Biopsy-Naïve Men: A Prospective Evaluation of Performance and Biopsy Strategies.

OBJECTIVES: This study aims to prospectively estimate the diagnostic performance of multiparametric prostate MRI (mpMRI) and compare the detection rates of prostate cancer using cognitive targeted transrectal ultrasound (TRUS) guided biopsies, targeted MR-guided in-bore biopsies (MRGB), or both methods combined in biopsy-naïve men. METHODS: The biopsy-naïve men referred for mpMRI (including T2-weighted, diffusion-weighted and dynamic contrast enhanced MRI) due to prostate cancer suspicion (elevated prostate-specific antigen or abnormal digital rectal examination) were eligible for inclusion. The images were scored according to Prostate Imaging Reporting and Data System (PI-RADS) v2, and men with PI-RADS 1-2 lesions were referred for routine systematic TRUS, while those with PI-RADS 3-5 lesions were randomized to MRGB or cognitive targeted TRUS. Men randomized to MRGB were referred to a secondary TRUS 2 weeks after MRGB. Gleason grade group ≥2 was defined as clinically significant prostate cancer. The performance of mpMRI was estimated using prostate cancer detected by any biopsy method as the reference test. RESULTS: A total of 210 men were included. There was no suspicion of prostate cancer after mpMRI (PI-RADS 1-2) in 48% of the men. Among these, significant and insignificant prostate cancer was diagnosed in five and 11 men, respectively. Thirty-five men who scored as PI-RADS 1-2 did not undergo biopsy and were therefore excluded from the calculation of diagnostic accuracy. The overall sensitivity, specificity, negative predictive value, and positive predictive value of mpMRI for the detection of significant prostate cancer were 0.94, 0.63, 0.92, and 0.67, respectively. In patients with PI-RADS 3-5 lesions, the detection rates for significant prostate cancer were not significantly different between cognitive targeted TRUS (68.4%), MRGB (57.7%), and the combination of the two biopsy methods (64.4%). The median numbers of biopsy cores taken per patient undergoing systematic TRUS, cognitive targeted TRUS, and MRGB were 14 [8-16], 12 [6-17], and 2 [1-4] respectively. CONCLUSIONS: mpMRI, in a cohort of biopsy-naïve men, has high negative predictive value, and our results support that it is safe to avoid biopsy after negative mpMRI. Furthermore, MRGB provides a similar diagnosis to the cognitive targeted TRUS but with fewer biopsies.

The perils of penile enhancement: case report of a fulminant penile infection.

BACKGROUND: Penile enhancement with injectable agents is a rising trend and yet has received little scientific attention despite the potential for serious complications. These include cosmetic, functional and systemic complications that may require complex penile reconstructive surgery. We report a case of delayed severe infection following penile filler insertion leading to multi-organ failure and intensive care support. CASE PRESENTATION: A 31-year-old man presented with fevers and progressive pain and swelling of the penile shaft, 3 days after unprotected sexual intercourse. The patient received subcutaneous hyaluronic filler injections at a cosmetic clinic for penile enlargement two months prior to presentation. Relevant social history include polysubstance abuse and multiple sexual partners. Physical examination revealed gross penile oedema and erythema, with a ventral curvature of the penile shaft and a superficial abrasion on the distal ventral penile shaft. Within 24 h the patient developed septic shock with anuria, hypotension and fevers to 40 °C, requiring transfer to the Intensive Care Unit (ICU) for vasopressor and inotropic support. Intraoperative penile exploration revealed multiple pus stained fillers which were drained and grew Streptococcus Pyogenes on cultures. There was no abscess or evidence of necrotising fasciitis intraoperatively. The patient improved with intravenous antibiotics and was stepped down from the ICU after four days and discharged on day eight. One month post admission there was significant superficial skin loss to both ventral and lateral aspect of the penis, with healthy granulation tissue at the base. The patient opted for conservative management with regular dressings. He reported normal sexual and urinary function three months post admission. CONCLUSION: This is the first published case of sepsis from a penile infection in the context of hyaluronic acid penile fillers. In an era of escalating demand for penile cosmetic procedures, there is an increasing need for early recognition and appropriate management of penile filler infections. We report an unusual case of a localised penile infection rapidly progressing to sepsis with multi-organ failure requiring intensive care support. The case demonstrates early surgical intervention with targeted antimicrobials can result in successful eradication of infection, with satisfactory cosmetic and functional outcomes for patients.
