“…Fortunately, the natural defenses of the lower urinary tract remain relatively intact despite the increased risk of infection associated with immunosuppression (2,4). The patients in the present series received prophylaxis for cytomegalovirus and Pneumocystis jiroveci pneumonia as part of a tacrolimus-based immunosuppression protocol.…”

“…The purpose of the present study was to evaluate potential benefits and complications associated with early removal of invasive bladder catheters in the immediate posttransplant period after living donor renal transplantation. Almost 60% of bacteremias in renal transplant patients are reported to originate in the urinary tract, while catheters are the major source of nosocomial infections and sepsis (1,2). Although some studies (3,4) address duration of bladder catheterization, there does not seem to be a general consensus.…”

“…7 In addition, some studies have suggested that antibiotic prophylaxis may also reduce the risk of catheter-related UTIs, although it is not recommended for this purpose. 8,9 Most studies on catheter-related UTIs define bacteriuria as the primary outcome; in fact, this term is often used as a synonym for UTI. However, the difference between the two is clinically relevant, since catheter-related asymptomatic bacteriuria is seldom associated with adverse outcomes and generally does not require treatment.…”

Urinary tract infection and indwelling urinary catheters: prospective study in gynecological surgery with antibiotic prophylaxis

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 coli grew 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 de Klebsiella 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: Houv...

Catheter-associated urinary infection in kidney post-transplant patients

Abstract: Infection urinary does not occur during the period of urethral catheterization in kidney post-transplant patients. Thus, antimicrobial prophylaxis is not recommended for these patients to prevent urinary infection.
