Abstract
Introduction

Renal transplantation is the renal replacement therapy of choice in patients with end-stage chronic kidney disease. Major urological complications such as urinary leakage, ureteral stricture and urinary tract infection, usually occur in the first three months post-transplantation and lead to a higher morbidity and mortality and lower graft function.

Objective

To evaluate the impact of double J catheter colocation on major urological complications in extravesical ureteroneocystostomy in renal recipients.

Methods

Open clinical trial. The study included renal transplant recipients who underwent extravesical ureteroneocystostomy with trans-surgical placement of double J catheter compared to extravesical ureteroneocystostomy without trans-surgical catheter placement. The study variables were urinary leakage, ureteral stricture, urinary tract infection, surgical complications and graft function.

Results

84 patients were included, 42 patients in the study group and 42 in the control group, who had a mean follow-up of 10.7 months. Of the urological complications presented: 4 (4.8%) patients with urinary leakage, all in the non-catheter group (RR 0.475 95% CI 0.377−0.598, p = 0.04); 2 (2.4%) patients with ureteral stricture, one in each group (RR 1 95% CI 0. 246−4.066, p = 1.0); and 20 (23.8%) patients with urinary tract infection, being 9 (21.4%) patients in the control group and 11 (26.2%) in the study group (RR 1.135 CI 95% 0.710–1.817, p = 0.608). No differences regarding graft function were observed.

Conclusion

Our study showed a significant reduction in the incidence of urinary leakage with prophylactic ureteral catheter use, although no significant association was observed with other complications such as ureteral stricture or surgical complications. Furthermore, its use was not significantly associated with urinary tract infections or graft dysfunction.

Resumen
Introducción

El trasplante renal es la terapia de reemplazo renal de elección. Las complicaciones urológicas mayores aparecen en los primeros tres meses postrasplante y condicionan una mayor morbimortalidad y menor función del injerto.

Objetivo

Evaluar el impacto del catéter doble J sobre las complicaciones urológicas mayores en la ureteroneocistostomía extravesical en receptores renales.

Material y métodos

Ensayo clínico abierto. Se incluyeron pacientes receptores de trasplante renal, a los cuales se les realizó ureteroneocistostomía extravesical con colocación de catéter doble J en comparación con ureteroneocistostomía extravesical sin catéter. Se estudió la fuga urinaria, estenosis ureteral, infección urinaria, complicaciones quirúrgicas y función del injerto.

Resultados

Se incluyeron 84 pacientes, 42 en el grupo de estudio y 42 en el de control, con un seguimiento promedio de 10.7 meses. De las complicaciones urológicas presentadas: 4 (4.8%) pacientes con fuga urinaria, todos sin catéter (RR 0.475 IC95% 0.377–0.598, p = 0.04); 2 (2.4%) con estenosis ureteral, uno en cada grupo (RR 1 IC95% 0.246–4.066, p = 1.0); y 20 (23.8%) pacientes con infección urinaria, siendo 9 (21.4%) pacientes en el grupo control y 11 (26.2%) en el grupo de estudio (RR 1.135 IC95% 0.710–1.817, p = 0.608). No se observaron diferencias en relación a la función del injerto.

Conclusión

Nuestro estudio mostró reducción en la incidencia de fuga urinaria con el uso profiláctico de catéter, aunque no se observó una asociación con otras complicaciones como la estenosis ureteral o complicaciones quirúrgicas. Además, su uso no se relacionó con infecciones urinarias ni disfunción del injerto.
