    Introducci贸n. La infecci贸n del tracto urinario (ITU) es com煤n en receptores de trasplante renal (TR). La frecuencia de ITU depende de factores previos y posteriores al trasplante. Objetivos. Determinar la cronolog铆a de aparici贸n de ITU sintom谩tica, los microorganismos causantes y la incidencia de ITU resistente a antibi贸ticos en receptores de TR. Dise帽o. Estudio retrospectivo. Lugar. Unidad de Trasplante Renal, Hospital Edgardo Rebagliati Martins, EsSalud, Lima, Per煤. Participantes. Pacientes sometidos a TR. Intervenciones. Se revis贸 la historia cl铆nica de 304 pacientes sometidos a TR en el per铆odo 2002-2011, con seguimiento de hasta cuatro a帽os por paciente. Se constat贸 215 episodios de ITU sintom谩tica confirmada mediante urocultivo en 84 receptores. Principales medidas de resultados. Incidencia, cronolog铆a, determinaci贸n microbiol贸gica/ susceptibilidad, resistencia bacteriana, factores de riesgo, estrategias diagn贸sticas, presencia o no de bacteriemia y manejo terap茅utico. Resultados. En 50% de los 84 receptores el episodio inicial ocurri贸 durante los primeros tres meses, y en 39% se constat贸 m谩s de un episodio de ITU. Las bacterias representaron la etiolog铆a m谩s frecuente (94%), siendo la Escherichia coli (77%) el uropat贸geno prevalente, con tasa productora betalactamasa espectro extendido (BLEE) en 38%, seguida de Klebsiella pneumonie (11%) con BLEE 65%. En 12% de los 215 episodios de ITU el hemocultivo fue positivo. Entre los factores de riesgo se detect贸 luego del trasplante 19% receptores con anormalidades anat贸micas del tracto urinario. Conclusiones. La ITU ocurri贸 tempranamente luego del trasplante y la Escherichia coli fue el microorganismo etiol贸gico m谩s frecuente. La resistencia antibi贸tica estuvo presente en 37% de los 215 episodios de ITU, representando un desaf铆o cont铆nuo a resolver en la pr谩ctica cl铆nica.Introduction. Urinary tract infections (UTI) are common among renal transplant recipients (RTR) and their frequency depends on pre- and post-transplant factors. Objectives. To determine the time of appearance of symptomatic UTI among renal transplant recipients, microorganisms causing the infection, and incidence of UTI resistant to antibiotics. Design. Retrospective study. Setting. Renal Transplant Unit, Hospital Edgardo Rebagliati Martins, EsSalud, Lima, Peru. Participants. Patients who have undergone renal transplantation. Interventions. The clinical records of 304 patients subject to kidney transplantation performed between 2002 and 2011 and followed for up to four years were reviewed. There were 215 urine culture-confirmed UTI episodes in 84 transplant recipients. Main outcome measures. Incidence, chronology, microbiological determination/ susceptibility, bacterial resistance, risk factors, diagnostic strategies, presence or absence of bacteremia, and therapeutic management. Results. In 42 of the 84 recipients, the initial episode occurred during the first three months, and 33 (39%) had more than one UTI episode. Bacteria represented the most common etiology (94%), and Escherichia coli was the most prevalent uropathogen, with an extended-spectrum beta-lactamase (ESBL) production rate of 38%, followed by Klebsiella pneumoniae (11%) with an ESBL of 65%. Blood culture was positive in 25 (12%) of the 215 UTI episodes. In 17 recipients (19%), anatomic anomalies of the urinary tract were detected following the transplant. Conclusions. UTI occurred early following kidney transplantation, and Escherichia coli was the most common microorganism found. Antibiotic resistance was present in 79 (37%) of the 215 UTI episodes, representing a continuous challenge in clinical practice
