Factores de riesgo para infección del tracto urinario asociado al uso de catéter urinario permanente en pacientes adultos hospitalizados / Risk factors for urinary tract infection associated with the use of urinary catheters in hospitalized adult

Resumen La infección del tracto urinario asociada al catéter urinario permanente (ITU/CUP) es un problema relevante en los centros de salud por su alta frecuencia. Objetivo: Identificar factores de riesgo de ITU en pacientes adultos con CUP. Material y Método: Estudio caso control efectuado entre los años 2010-2016 en el Hospital Militar de Santiago. Se realizó un análisis estadístico univariado y multivariado por medio del modelo de regresión logística binaria, con variables como edad, duración e indicación del dispositivo, algunas comorbilidades y la instalación del dispositivo luego de 15 días hospitalización. Resultado: Se obtuvo un total de 63 casos y 123 controles. Fueron variables predictoras de ITU/CUP la duración del CUP desde el séptimo día en adelante (OR 2,6 IC 1,4-4,9, p = 0,004) y la instalación del CUP con una estadía de hospitalización previa de 15 días y más (OR 7,8 IC 2,920,9 p = 0,000). No se encontró asociación con la edad mayor de 80 años, comorbilidades como diabetes y vejiga neurogénica e indicación de instalación. Conclusiones: Los resultados permiten focalizar las intervenciones, evaluando la necesidad real de indicación de CUP en pacientes con estadía hospitalaria previa de dos semanas y fomentar el retiro de CUP antes del séptimo día de uso.

Abstract Catheter-associated urinary tract infection (CAUTI) is a relevant problem in health centers because of its high frequency. Objective: To identify UTI risk factors in adult patients with urinary catheter. Material and Method: Control case study carried out between the years 2010-2016 at the Military Hospital of Santiago, Chile. Univariate and multivariate statistical analysis were performed using the binary logistic regression model, variables such as age, duration and indication of the device, some comorbidities and the installation of the device after 15 days of hospitalization. Result: A total of 63 cases and 123 controls were obtained. Predictive variables of CAUTI for the duration of the urinary catheter from the 7th day onwards (OR 2.6 IC 1.4-4.9, p = 0.004) and the installation of the urinary catheter with a previous hospital stay of 15 days and more (OR 7.8 CI 2.9-20.9 p = 0.000). No association was found in age over 80 years, comorbidities such as diabetes and neurogenic bladder and indication. Conclusions: The results permitted to focus the interventions, evaluating the real need for indication of CUP in patients with previous hospital statistics of 2 weeks and encouraging the withdrawal of CUP before the 7th day of use.

The course of alterations in ureteral jet dynamics following kidney transplantation: a prospective observational cohort study

SUMMARY OBJECTIVES To prospectively investigate the alterations and normal ranges of ureteral jet dynamics after double-J-stent (DJS) removal in patients who underwent renal transplantation (RTx). METHODS Patients who underwent RTx were prospectively evaluated between November 2017 and June 2018. After RTx, Doppler ultrasonography (D-US) was performed on all patients after DJS removal. Renal artery resistive index (RA-Ri), renal pelvis anterior-posterior diameter (RP-APD), pelvicalyceal system dilation (PCSD), and ureteral jet flow dynamics (maximum and average velocity; JETmax and JETave) were measured by D-US. Also, patients' demographics, estimated glomerular filtration rate (eGFR) levels, and acute rejection were investigated in the study. Patients were assessed two different times by D-US, about 6 and 12 weeks after DJS removal, and the two different measurements were compared with the Wilcoxon test and Chi-square test. RESULTS A total of 25 patients were evaluated in the study. Nonobstructive PCSD rate (12% vs 8%), JETave (18.8 vs 12.9 cm/sec), and JETmax (29.2 vs 20 cm/sec) levels were significantly decreased (p values are 0.01, 0.010 and 0.014, respectively). In addition, monophasic and square pattern rates were significantly observed to increase over time (p=0.035); however, ureteral jet patterns were correlated between the two different D-US measurements (R=0.225, p=0.032). CONCLUSION After RTx, dilation rate and ureteral jet flow velocities were significantly decreased, and monophasic and square JETpattern rates were significantly increased over time. Ureteral jet dynamics can provide useful information about the follow-up of peristaltic activity in the pelvic-ureteric system.

RESUMO OBJETIVOS Investigar prospectivamente as alterações e as variações normais da dinâmica do jato ureteral após a remoção do J-stent duplo (DJS) em pacientes submetidos a transplante renal (RTx). MÉTODOS Pacientes submetidos a RTx foram avaliados prospectivamente entre novembro de 2017 e junho de 2018. Após o RTx, o D-US foi realizado em todos os pacientes após a remoção do DJS. Índice de resistência da artéria renal (RA-Ri), diâmetro ântero-posterior da pelve renal (AP-DPR), dilatação do sistema pelvicaliceal (PCSD) e dinâmica do jato ureteral (velocidade máxima e média; JETmax e JETave) foram medidos por D-US. Além disso, a demografia dos pacientes, os níveis estimados de taxa de filtração glomerular (eGFR) e a rejeição aguda foram investigados no estudo. Os pacientes foram avaliados em dois momentos diferentes pelo D-US, cerca de 6 e 12 semanas após a remoção do DJS, e as duas medidas diferentes foram comparadas com o teste de Wilcoxon e o teste do qui-quadrado. RESULTADOS Um total de 25 pacientes foi avaliado no estudo. Taxa de PCSD não obstrutiva (12% vs. 8%), JETave (18,8 vs. 12,9 cm/seg) e JETmax (29,2 vs. 20 cm/seg), os níveis foram significativamente diminuídos (valores de p são 0,01, 0,010 e 0,014, respectivamente). Além disso, as taxas de padrão monofásico e quadrado foram significativamente observadas para aumentar ao longo do tempo (p=0,035); no entanto, padrões de jato ureteral foram correlacionados entre as duas diferentes medidas D-US (R=0,225, p=0,032). CONCLUSÃO Após o RTx, a velocidade de dilatação e as velocidades de fluxo do jato ureteral foram significativamente diminuídas e as taxas de JET padrão monofásico e quadrado foram significativamente aumentadas ao longo do tempo. A dinâmica do jato ureteral pode fornecer informações úteis sobre o acompanhamento da atividade peristáltica no sistema pélvico-ureteral.

Representantes de la Sociedad Argentina de Infectología (SADI) y la Sociedad Argentina de Terapia Intensiva (SATI) acordaron la elaboración de recomendaciones de diagnóstico, tratamiento y prevención de la infección del tracto urinario asociada a sonda vesical (ITU-SV). La metodología utilizada fue el análisis de la bibliografía publicada en 2006-2016, complementada con la opinión de expertos y datos epidemiológicos locales. En este documento se pretende ofrecer herramientas básicas de optimización de diagnóstico en base a criterios clínicos y microbiológicos, orientación en los esquemas antibióticos empíricos y dirigidos, y promover las medidas efectivas para reducir el riesgo de ITU-SV. Se destaca la preocupación por el control y tratamiento inadecuados de la ITU-SV, en particular el uso indiscriminado de antimicrobianos y la importancia de garantizar la mejora en las prácticas diarias. Se establecen pautas locales para mejorar la prevención, optimizar el diagnóstico y tratamiento de la ITU-SV, y así disminuir la morbimortalidad, los días de internación, los costos y la resistencia a antibióticos debidos al mal uso de los antimicrobianos.

Representatives of the Argentine Society of Infectious Diseases (SADI) and the Argentine Society of Intensive Therapy (SATI) issued the present recommendations on diagnosis, treatment, and prevention of catheter associated urinary tract infection (CA-UTI). Articles published during 2006-2016 were analyzed in the light of experts' opinion and local data. This document aims to offer basic strategies to optimize the diagnosis based on clinical and microbiological criteria, provide guidance in empirical and targeted antibiotic schemes, and promote effective measures to reduce the risk of CA-UTI. The joint work of both societies highlights the experts' concern about the mismanagement of CA-UTI, which is associated to the indiscriminate use of antimicrobials, and the importance of improving daily practices of CA-UTI management. Through these recommendations, local guidelines are established to optimize the diagnosis, treatment and prevention of CAUTI in order to reduce morbimortality, days of hospitalization, costs and antibiotic resistance due to the misuse of antimicrobials.

Can hydrophilic coated catheters be beneficial for the public healthcare system in Brazil? - A cost-effectiveness analysis in patients with spinal cord injuries

ABSTRACT Introduction Detrusor sphincter dyssynergia affects 70% to 80% of all spinal cord injury patients, resulting in increased risk of urinary tract infections (UTIs) and potential exposure to antimicrobial resistance. In Brazil, local guidelines recommend intermittent catheterization as the best method for bladder emptying, and two catheter types are available: the conventional uncoated PVC and the hydrophilic coated catheters. Objective To evaluate the cost-effectiveness of two types of catheters for intermittent catheterization from the perspective of the Brazilian public healthcare system. Materials and Methods A Markov model was used to evaluate cost-effectiveness in those with spinal cord injuries. A primary analysis was conducted on all possible adverse events, and a secondary analysis was performed with urinary tract infections as the only relevant parameter. The results were presented as cost per life years gained (LYG), per quality-adjusted life years (QALY) and per number of urinary tract infections (UTIs) avoided. Results The base scenario of all adverse events shows a cost-effective result of hydrophilic coated catheters compared to uncoated PVC catheters at 57,432 BRL (Brazilian Reais) per LYG and 122,330 BRL per QALY. The secondary scenario showed that the use of hydrophilic coated catheters reduces the total number of UTIs, indicating that an additional cost of hydrophilic coated catheters of 31,240 BRL over a lifetime will reduce lifetime UTIs by 6%. Conclusions Despite the higher unit value, the use of hydrophilic coated catheters is a cost-effective treatment from the perspective of the Brazilian public healthcare system.

Epidemiología de las infecciones urinarias asociadas a catéter y no asociadas a catéter en un hospital universitario de tercer nivel / Nosocomial urinary tract infection: an analysis beyond urinary catheterization

Resumen Introducción: Las infecciones urinarias asociadas a la atención de la salud (ITU-AAS) representan un importante problema sanitario, siendo poco conocidas sus características cuando no están asociadas a cateterización urinaria u ocurren fuera de unidades de cuidados intensivos (UCI). Objetivos: Determinar las características de los pacientes con ITU-AAS, etiología y susceptibilidad antimicrobiana de las mismas, tanto asociadas a catéter (ITU-C) como no asociadas a catéter (ITU-noC), en UCI y en sala general. Materiales y Métodos: Se realizó un estudio analítico retrospectivo de corte transversal entre 2009 y 2013 en un hospital universitario de tercer nivel. Se identificaron todos los episodios de ITU-AAS, diferenciándolas en ITU-C e ITU-noC. Resultados: Se incluyeron 253 episodios de ITU-AAS, siendo más frecuentes las ITU-C (60,9%) respecto a ITU-noC. Un 37,4% de ITU-noC y 59,7% de ITU-C ocurrieron en UCI. Los microorganismos aislados más frecuentemente fueron Escherichia coli, Klebsiella pneumoniae y Enterococcus sp. El 19% de los bacilos gramnegativos fueron productores de β-lactamasa de espectro extendido, siendo su frecuencia similar en ambos grupos. Conclusión: Las co-morbilidades de los pacientes con ITU-AAS, los agentes etiológicos responsables y sus correspondientes espectros de sensibilidad, fueron similares en los grupos de ITU-C e ITU-noC, tanto en sala general como en UCI.

Introduction: Nosocomially acquired urinary tract infections (NAUTI) represent an important public health issue, but its characteristics when they are not catheter associated (CA-UTI) or when they take place outside intensive care units (ICU) are poorly understood. Objectives: To determine the patients' characteristics, etiology and antimicrobial susceptibility of NAUTI, both CA-UTI and no CA-UTI, in general ward and ICU. Methods: We conducted a retrospective analytic cross-sectional study, between 2009 and 2013, in a third level universitary hospital. All NAUTI episodes were identified, classifying them as CA-UTI and no CA-UTI. Results: We included 253 episodes of NAUTI, being CA-UTI (60,9%) more frequent than no CA-UTI. A 37,4% of no CA-UTI and 59,7% of CA-UTI were identified in ICU. The most frequently isolated microorganisms were Escherichia coli, Klebsiella pneumoniae and Enterococcus sp. A 19% of extended spectrum betalactamase producing gram negative bacilli were found, without differences between groups. Conclusion: Patients's comorbidities, microorganisms associated to NAUTI and its antimicrobial susceptibility were similar in CA-UTI and no CA-UTI, as in general ward and ICU.

Traumas uretrais pela introdução do cateter uretral: conduta do enfermeiro / Urethral traumas by the introduction of urethral catheter: conduct of nurses

Este estudo teve como objetivo avaliar a conduta do enfermeiro frente ao traumatismo de uretra ocasionado pela inserção do cateter uretral. Este estudo teve aprovação do Comitê de Ética em pesquisa da Escola de Enfermagem de Ribeirão Preto - Parecer 466/12 e foi realizado em um Hospital Universitário em duas etapas: na primeira etapa, descritiva, foi efetuada consulta ao sistema eletrônico do hospital que trata de notificações sobre eventos adversos dos pacientes. Nessa etapa foi utilizado instrumento de perguntas objetivas elaborado pelo próprio pesquisador. Na segunda, quase-experimental pós teste, foram coletados os dados relacionados a autoconfiança de enfermeiros, que participaram de cenário simulado de baixa fidelidade. Nessa etapa para obtenção dos dados foi aplicado um questionário de caracterização dos sujeitos e instrumento já validado, de autoconfiança na Assistência de Enfermagem à Retenção Urinária (EAAERU), a qual encontra-se dividida em cinco fatores: 1) "Intervenções realizadas durante o cateterismo urinário e/ou em situações iatrogênicas", 2) "Intervenções prévias ao cateterismo urinário", 3) "Intervenções realizadas após o cateterismo urinário"; 4) "Comunicação, consentimento e preparo dos materiais para realização do cateterismo urinário", e 5) "Avaliação objetiva da RU" (retenção urinária). Os dados da primeira etapa foram analisados por estatística descritiva e os dados da segunda etapa foram codificados e digitados duplamente em planilhas do aplicativo Excel®, exportados e analisados no programa SPSS (Statistical Package for Social Science) ®, versão 22.0, como a escala original. Os resultados demonstram que na primeira fase do estudo entre as 5300 notificações do serviço, apenas 27 (1,96%) estavam relacionadas a problemas urinários. Entre essas, cinco diretamente ao cateterismo urinário. Na segunda fase do estudo, a amostra foi composta por 53 enfermeiros, entre os quais a maior parte era do sexo feminino, com idade média de 36 anos, menos de dez anos de formação. Entre eles a maioria cursava ou já haviam cursado pós-graduação. Segundo os entrevistados todos 53 (100,0%) já realizaram o cateterismo urinário e 46 (86,8%) já vivenciaram dificuldades no procedimento. A maioria já avaliou trauma uretral ocasionado pela passagem do cateter. A conduta tomada nessa circunstância foi comunicar o fato e solicitar avaliação de outro profissional (médico e/ou outro enfermeiro). Após atividade simulada de trauma uretral, na avaliação da autoconfiança, a EAAERU demonstrou boa confiabilidade na sua aplicação (? 0,966). Os menores escores encontrados na autoconfiança dos profissionais estiveram relacionados aos fatores 1) "Intervenções realizadas durante o cateterismo urinário e/ou em situações iatrogênicas" e 5) "Avaliação objetiva da RU". Observou-se ainda associação positiva entre a autoconfiança e a frequência de realização do cateterismo urinário. Conclui-se que os traumas de uretra são comuns na prática clínica, porém pouco notificados. Com relação à autoconfiança na introdução do cateterismo urinário em que ocorrem situações de trauma de uretra há dificuldade na tomada de decisão e na avaliação objetiva da RU. Uma vez que o cateterismo é de competência do enfermeiro, são necessários programas e instrumentos que capacitem os profissionais para tais situações

This study aimed to evaluate the conduct of the nurse to the urethral trauma caused by the insertion of urethral catheter. This study was approved by the Ethics Committee in research of the College of Nursing in Ribeirão Preto - Opinion 466/12 and was performed in University Hospital in two stages: in the first stage, descriptive, a question was made on the hospital's electronic system, which deals with notifications about adverse events of patients. In this stage, it was used an instrument of objective questions elaborated by the researcher herself. In the second stage, quasi-experimental posttest study, the data related to self-confidence of nurses who participated in simulated low-fidelity scenario was collected. In this stage, to obtain the data, it was applied a characterization questionnaire of subjects and already validated instrument of Self-Confidence Scale of Nursing Care in Urinary Retention (EAAERU), which is divided in five factors: 1) "Interventions performed during urinary catheterization and/or in iatrogenic situations", 2) "Prior interventions to performing urinary catheterization", 3) "Interventions performed for urinary catheters"; 4) "Communication, consent and preparation of materials for performing urinary catheterization", and 5) "Objective evaluation of the urinary retention". The first stage's data were analyzed by descriptive statistic and the second stage's data were codified and double typed in spreadsheets in the Excel® app, exported and analyzed in the SPSS program (Statistical Package for Social Science)®, version 22.0, like the original scale. The results demonstrate that in the first stage of the study, among the 5300 notifications of service, only 27 (1,96%) were related to urinary problems. Among these, five directly related to urinary catheterization. In the second stage of the study, the sample was made by 53 nurses, among which most were women, with an average age of 36 years, less than ten years of formation. Among them, most were attending or had already attended postgraduate. According to the interviewers, all 53 (100,0%) had performed urinary catheterization and 46 (86,8%) had gone through trouble during the process. Most of them had evaluated urethral trauma caused by the introduction of the catheter. The conduct taken in this circumstance was to communicate the fact and request the evaluation of another professional (Doctor and/or another nurse). After simulated activity of the urethral trauma, in the self-confidence evaluation, EAAERU showed good reliability on its application (?=0,966). The lowest scores found in the professionals' self-confidence were related to the factors 1) "Interventions performed during urinary catheterization and/or in iatrogenic situations" and 5) "Objective evaluation of the urinary retention". It was also observed positive association between the self-confidence and the performance of urethral catheterization. It is concluded that urethral traumas are common on clinical practice, however little notified. With regard to self-confidence to the introduction of urethral catheterization in which occur urethral trauma situations, there is difficulty in decision making and objective evaluation of the urinary retention. Once the catheterization is the nurse's responsibility, programs and tools are necessary to enable professionals in such situations

Complications after bladder augmentation in children

PURPOSE : Bladder augmentation is an effective surgical procedure for increasing bladder capacity and reducing pressure on the urinary system. It is indicated for patients with anomalies such as spina bifida, myelomeningocele, urethral valve and bladder exstrophy, who progress with low tolerance of medication. CASES : This was a retrospective study conducted on pediatric patients submitted to bladder augmentation from 2000 to 2011. RESULTS : 34 patients aged 4 to 17 years were submitted to bladder augmentation, 30 of them with an ileal loop and 4 with a ureter.A continent urinary shunt was performed in 16 patients, the Mitrofanoff conduit was associated in 15, and the Macedo technique was used in one. Mean follow-up was 34.35 months (1 to 122 months). Mean creatinine was 1.5 ng/ml (0.4 to 7.5 ng/ml) preoperatively and 1.78 ng/ml postoperatively. Three patients required a renal transplant during follow-up. There was improvement or resolution of vesicoureteral reflux in 83.5% of the kidneys on the right and in 75% on the left. Bladder capacity increased, on average, from 152.5 ml to 410 ml. The main complications were vesical lithiasis in 3 patients and conduit perforation in one. CONCLUSION : Bladder augmentation showed good results in this series, preserving renal function in most of the patients.

Urinary tract infection and indwelling urinary catheters: prospective study in gynecological surgery with antibiotic prophylaxis / Infecção do trato urinário e cateter vesical de demora: um estudo prospectivo em cirurgia ginecológica com antibioticoprofilaxia

ABSTRACT CONTEXT AND OBJECTIVES: Urinary tract infections are the most common cause of hospital-acquired infections, and the use of indwelling urinary catheters is a predisposing factor for their development. The aims of this study were to estimate the frequency of pre and postoperative bacteriuria, identify the microorganisms involved, count the colony-forming units, determine the antibiotic sensitivity profile and compare the results from pre and postoperative urinalyses among women undergoing gynecological surgery with implantation of a urinary catheter. DESIGN AND SETTING: Non-controlled prospective observational single-cohort epidemiological study carried out at a university hospital. METHODS: Urine samples were collected before and 24 hours after catheterization for urinalysis, culturing and antibiotic sensitivity testing. Pre and postoperative urinalyses were compared using Wilcoxon and McNemar non-parametric tests. RESULTS: Fifty-one women participated in the study. Escherichia coligrew in six preoperative samples (11.8%) and Klebsiella pneumoniae in one (1.9%), but bacterial growth did not occur in any postoperative sample. Urinalysis showed lower number of pus cells in the postoperative urine samples (P < 0.05). There were no differences in red blood cell counts or in the nitrite and leukocyte esterase tests, between the samples. CONCLUSION: Bacteriuria was found in 13.7% of the preoperative samples. Gram-negative bacteria sensitive to most antibiotics were identified. In the postoperative samples, no bacterial growth was observed. Urinalysis only showed significant reduction of leukocyturia in the postoperative period.

RESUMO CONTEXTO E OBJETIVOS: As infecções urinárias são a causa mais comum de infecções hospitalares, e o uso de cateteres de demora é fator predisponente para o seu desenvolvimento. Os objetivos deste estudo foram estimar a frequência de bacteriúria pré e pós-operatória, identificar os germes encontrados, a contagem de unidades formadoras de colônias e o perfil de sensibilidade aos antibióticos, além de comparar os resultados dos exames de urina pré- e pós-operatórios em mulheres submetidas a cirurgias ginecológicas com cateterismo vesical. TIPO DE ESTUDO E LOCAL: Estudo epidemiológico, observacional, de coorte única, prospectivo, não controlado, realizado em hospital universitário. MÉTODOS: Amostras de urina foram colhidas antes da cateterização e após 24 horas para urinálise, cultura e antibiograma. Os resultados da urinálise no pré- e pós-operatório foram comparados utilizando-se os testes não paramétricos de Wilcoxon e McNemar. RESULTADOS: Participaram do estudo 51 mulheres. Houve crescimento de Escherichia coli em seis amostras pré-operatórias (11,8%) e deKlebsiella pneumoniae em uma (1,9%), mas não houve crescimento bacteriano em nenhuma amostra pós-operatória. A urinálise mostrou menor quantidade de piócitos na amostra de urina pós-cirúrgica (P < 0,05). Não houve diferença quanto ao número de hemácias e às reações para nitrito e leucocitesterase, entre as amostras. CONCLUSÃO: Houve bacteriúria em 13,7% das amostras pré-operatórias, sendo identificadas bactérias Gram-negativas sensíveis à maioria dos antibióticos. Não foi observado crescimento bacteriano nas amostras pós-operatórias. A urinálise mostrou somente redução significativa da leucocitúria no pós-operatório.

Impacto del cobre en la reducción de infecciones intrahospitalarias, mortalidad y gasto en antimicrobianos en una Unidad de Cuidados Intensivo de adultos / Impact of copper in the reduction of hospital-acquired infections, mortality and antimicrobial costs in the Adult Intensive Care Unit

We conducted a clinical trial to determine the impact of coating surfaces with copper in reducing hospital-acquired infections, mortality associated with nosocomial infections and antimicrobial costs in the UCI. The study took place at Carlos Van Buren Hospital, Valparaíso, Chile. No differences in the frequency of nosocomial infections were found. Not in rates of ventilator-associated pneumonia (p = 0.9), nor in catheter- associated urinary tract infection (p = 0.9) or in central venous catheter associated bacteremia (p = 0.3). There were no differences in infection-free survival (p = 0.9). There were less costs of antimicrobials in patients in which copper was used. The fact that the sample size was not completed could explain that no significant differences in infections were found. Conclusion: The use of copper as a surface in the ICU showed no statistically significant differences in rates of nosocomial infections during the study period, however, these results could be related to the sample size.

Introducción: Las infecciones nosocomiales incrementan la mortalidad y costos en las instituciones de salud. El revestimiento con cobre, de superficies de alto contacto en la unidad clínica en torno a los pacientes, reduce la colonización bacteriana de las mismas. Objetivo: Determinar el impacto del revestimiento de las superficies con cobre en la disminución de las infecciones intrahospitalarias, la mortalidad asociada a las infecciones intrahospitalarias y los costos en antimicrobianos en pacientes hospitalizados en UCI adultos en el Hospital Carlos Van Buren. Pacientes y Métodos: Estudio prospectivo, comparativo, mayo de 2011-mayo de 2012. Asignación aleatoria de pacientes adultos ingresados en UCI, que permanecieran al menos por 24 h en dicha unidad, a unidades de aislamiento recubiertas (n: 7) o no recubiertas con cobre (n: 7). Resultados: Ingresaron al estudio 440 pacientes, 217 pacientes (49,3%) en el grupo sin cobre y 223 en el grupo con cobre (50,7%). No se encontraron diferencias en la frecuencia de infecciones intrahospitalarias en ambos grupos. Tampoco se encontraron diferencias significativas en las tasas de neumonía asociada a ventilación mecánica (p = 0,9), infección urinaria asociada a catéter urinario (p = 0,9) y bacteremias asociada a catéter venoso central (p = 0,3). Tampoco se encontraron diferencias en la sobrevida libre de infección (p = 0,9). Se encontró un gasto menor de antimicrobianos en pacientes atendidos en unidades revestidas con cobre. Durante el período del estudio no se completó el tamaño de muestra y las diferencias no significativas podrían deberse a este hecho. Conclusión: El uso del cobre como revestimiento de las superficies hospitalarias en UCI, mostró diferencia en la tasa de bacteriemia asociada a dispositivos venosos, aunque no significativa, y no mostró diferencia en neumonías e infecciones urinarias. Las diferencias no significativas pueden deberse a que no se completó el tamaño de la muestra. Se observó un mayor gasto de antimicrobianos en pacientes de unidades no cobrizadas, lo que plantea una nueva área de investigación.

Long-term results of permanent memotherm urethral stent in the treatment of recurrent bulbar urethral strictures

Purpose: To evaluate the long term outcomes of permanent Memotherm urethral stent in the treatment of recurrent bulbar urethral stricture. Materials and Methods: Twenty patients who underwent permanent Memotherm urethral stent implantation due to recurrent bulbar urethral stricture following previous unsuccessful surgical procedure from 1996 to 2002 were included in the study. Long-term outcomes of the patients were evaluated. Results: The overall success rate was 87.5% at the end of the tenth year. There was discomfort in implantation area in eight patients about 1 month following the procedure. These patients were treated with alpha-blocker and anti-inflammatory drugs. Stone formation was observed at the urethral stent implantation area in two patients. Post-void dripping has been observed in 15 patients up to the postoperative 3rd month. Stress urinary incontinence was observed in a patient with a 1-year follow-up. Partial stent migration was observed in two patients. None of the patients experienced pain during erection. Conclusion: Memotherm urethral stent is a minimal invasive surgical procedure which can be safely and effectively used in patients with recurrent urethral stricture. .

Ureteral Cannulation as a Complication of Urethral Catheterization

Urinary catheterization is a common procedure, particularly among patients with neurogenic bladder secondary to spinal cord injury. Urethral catheterization is associated with the well-recognized complications of catheter-associated urinary tract infections and limited genitourinary trauma. Unintentional ureteral cannulation represents a rare complication of urethral catheterization and has been previously described in only eight cases within the literature. We describe two cases of aberrant ureteral cannulation involving two patients with quadriplegia. These cases along with prior reports identify the spastic, insensate bladder and altered pelvic sensorium found in upper motor neuron syndromes as major risk factors for ureteral cannulation with a urinary catheter.

Complicações durante a internação de receptores de transplante renal / Complicaciones durante la hospitalización de receptores de trasplante renal / Complications during the hospitalization of kidney transplant recipients

O objetivo do estudo foi identificar complicações ocorridas em pacientes receptores de transplante renal. Coorte histórica realizada em hospital universitário entre janeiro de 2007 e janeiro de 2009 com amostra de 179 pacientes; dados coletados retrospectivamente em base de dados e prontuário e, em seguida, analisados estatisticamente. A média de idade dos pacientes foi de 43 (DP=13,7) anos, sendo 114 (63,7%) homens, 95 (65,1%) não fumantes e 118 (66,3%) receptores de doadores falecidos. As principais complicações foram rejeição 68 (32,1%) e infecção 62 (29,2%). Houve associação estatisticamente significativa entre rejeição e mediana dos dias de internação (p<0,001); dias de uso de cateter venoso central (p=0,010) e status tabágico (p=0,008); infecção e cateter venoso central (p=0,029), mediana dos dias de internação (p<0,001) e tempo de uso de sonda vesical (p=0,009). Concluiu-se ser importante diminuir os dias de internação e a permanência de cateteres, o que pode ser levado em consideração no planejamento do cuidado de enfermagem.

El objetivo del estudio fue identificar las complicaciones en los pacientes que recibieron trasplante renal. Cohorte histórica realizada en hospital universitario de enero/2007 hasta enero/2009 con una muestra de 179 pacientes, los datos recogidos retrospectivamente de la história clínica de los pacientes y analizados estadísticamente. La edad promedio de los pacientes fue 43(SD=13,7) años, 114(63,7%) hombres, 95(65,1%) no fumadores y 118(66,3%) receptores de donantes fallecidos. Las principales complicaciones fueron rechazo 68(32,1%) e infección 62(29,2%). Hay asociación estadísticamente significativa entre el rechazo y la mediana de días de hospitalización (p<0,001); días de uso de catéter venoso central (p=0,010) y tabaquismo (p=0,008); infección y catéter venoso central (p=0,029); mediana de días de hospitalización (p<0,001) y tiempo de uso del catéter urinario (p=0,009). Se concluye que es importante reducir los días de hospitalización y la permanencia de los catéteres, que puede ser considerado en la planificación de los cuidados de enfermería.

The objective of the study was to identify the complications in patients that have received a renal transplant. A Historical cohort performed in a university hospital from January/2007 through January/2009 with a sample of 179 patients; data collected retrospectively from the medical history of patients and submitted to statistical analyses. Mean age of patients was 43(SD=13.7) years, 114(63.7%) men, 95(65.1%) non smokers and 118(66.3%) received the graft from a deceased donor. The main complications were rejection 68(32.1%) and infection 62(29.2%). There was statistical significance between rejection and median days of hospital stay (p<0.001); days of use of central venous catheter (p=0,010) and smoking status (p=0.008); infection and central venous catheter (p=0.029); median days of hospital stay (p<0,001) and time of use of urinary catheter (p=0,009).It was concluded that it is important to reduce the days of hospital stay and permanence of catheters, which may be considered in the planning of nursing care.

Bladder decompression for chronic urinary retention may lead to upper tract bleeding.

Haematuria following decompression of a distended bladder is a well known condition. The bleeding in such cases originates in the bladder and resolves spontaneously. We describe an elderly man who had bleeding from the kidney following decompression of the bladder. This resulted in an extensive search for an upper tract tumour as a cause for haematuria.

Integrative review: evidences on the practice of intermittent/indwelling urinary catheterization / Revisão integrativa: evidências na prática do cateterismo urinário intermitente/demora / Revisión integrativa: evidencias en la práctica del cateterismo urinario intermitente/demora

OBJECTIVE: to seek the best evidence available in the literature concerning the knowledge produced and related to the techniques of intermittent and indwelling urinary catheterization, so as to place the nursing care given to patients submitted to urinary catheterization on a scientific foundation and to prevent urinary tract infections. METHOD: the literature search was undertaken in the Pubmed and Cochrane databases for the development of the integrative review. The sample was of 34 articles. These were analyzed by two independent researchers using an instrument adapted for ascertaining the level of evidence and the grade of recommendation, in addition to the use of the Jadad scale. RESULTS: the evidence available related to the nursing care for patients submitted to urinary catheterization is: the infection rate in the urinary tract does not alter whether the perineum is cleaned with sterile water or not, or with the use of povidone-iodine solution or chlorhexidine; or using clean or sterile technique. The use of an intermittent catheter with clean technique results in low rates of complications or infections compared to the use of an indwelling catheter. The removal of the catheter in up to 24 hours after surgery and the use of an antimicrobial-impregnated or hydrophilic-coated catheter reduce urinary tract infection . CONCLUSIONS: there are controversies in relation to periurethral cleansing technique, the type of material the catheter is made of, and some procedures for the maintenance and removal of the catheter. This review's results represent an updating of the nurse's conducts and decision-making for the prevention of urinary tract infections in urinary catheterization.

OBJETIVO: buscar as melhores evidências disponíveis na literatura sobre o conhecimento produzido e relacionado à técnica de cateterismo urinário intermitente e de demora, para embasar cientificamente o cuidado de enfermagem prestado ao paciente, submetido ao cateterismo urinário, e prevenir infecção do trato urinário. MÉTODO: a busca foi realizada nas bases de dados PubMed e Cochrane para o desenvolvimento da revisão integrativa. A amostra foi composta por 34 artigos. Esses foram analisados por dois pesquisadores independentes, usando-se instrumento adaptado para verificar o nível de evidência e grau de recomendação, além da utilização da escala de Jadad. RESULTADOS: as evidências disponíveis, relacionadas aos cuidados de enfermagem aos pacientes submetidos ao cateterismo urinário, são: a taxa de infecção no trato urinário não altera com a higienização do períneo com água estéril ou não, com o uso de solução de iodo-povidine ou clorexidine, ou aplicando técnica limpa ou estéril. O uso do cateter intermitente com técnica limpa implica em menores taxas de complicações e infecções em comparação com a de demora. A remoção do cateter em até 24 horas após cirurgia e o uso do cateter impregnado com antimicrobiano e de revestimento hidrofílico reduz a incidência de infecção do trato urinário. CONCLUSÕES: existem controvérsias em relação à técnica de higienização periuretral, tipo de material do cateter e alguns procedimentos para a manutenção e remoção do cateter. Os resultados desta revisão representam atualização das condutas e tomada de decisão do enfermeiro para a prevenção de infecção do trato urinário no cateterismo urinário.

Early removal of 3 way foleys catheter after transurethral resection of prostate in beneficial?

To compare the outcome of three way foleys catheter removed on 2[nd] and 5[th] day after Transurethral resection of Prostate for BPH regarding postoperative retention of urine, urine culture and hospital stay. Quasi Experimental study. This study was carried out in Department of Urology, University of Medical and health sciences Jamshoro from July 2010 to December 2011. This study consisted of 50 patients were divided in two groups. Group A for catheter was removed on 2nd post operative day of Trans Uretheral resection of prostate and group B for catheter was removed on 5th Post Operative Day of Trans Uretheral resection of prostate, each group consist of 25 patients. Detailed History was taken from all the patients with special regard to the urinary retention. Inclusion criteria were that all diagnosed as case of BPH on the basis of history and investigations. Exclusion criteria included unfit patients for general anesthesia, presented with chronic urinary retention, hematological disorders, pre operative infected urine and concurrent uretheral structure. Re-catheterization were in 2 patients [8%] group A and 1 patient [4%] in group B. Post operative urine culture growth of organism [bacteriuria] were 1 patient [4%] A and 3 patients [12%] in group B. Duration of hospital stay in group A was 5.68 as compared to the patients in group B was 8.44 days. In conclusion, early catheter removal had a dramatic impact on hospital stay. Catheters can be removed early after transurethral resection of prostate with no increase in morbidity and maintain the efficacy of the procedure, resulting in considerable savings to their patients. Our study confirms the safety of an irrigation-free and early catheter removal policy after TURP
