[Prognostic implications of urological complications in the renal transplantation].

We describe the urological complications occurred in 302 patients undergoing first cadaveric renal transplantation in 16 years in the University Hospital. two series can be distinguished: "Historical" (1976-86) and "Actual" (1986-92). Thirty patients (10%) presented 33 (11%) urological complications: 73% urinary fistula and 27% ureteral stenosis. The vast majority (80%) were early complications (before 90 days). No statistical difference was observed in the survival rates of both the patients and grafts presenting or not urinary complications, except in the last series. A multivariate analysis was performed to examine the influence of prognostic factors. These analysis revealed that cold ischemia time and organ retrieval were the technical variables significantly related with urologic complications among historical and global series. Only recipient age was associated with urologic complications in actual series.
