OBJECTIVE
The two major types of urologic problems after renal transplantation are urinary leakage and obstruction. In this study, we report the urological complications of renal transplantations performed in our hospital during a 22-year period.
METHODS
Between 1978 and 2000, 433 consecutive patients underwent renal transplantation. Of those transplants, 50 were cadavers and 383 were living-related donor transplantation. All ureteroneocystostomies were performed with the same technique described by Woodruff.
RESULTS
Urological complications developed in 19 (4.23%) recipients. Those complications were urinary leakage in 9 (2%), ureteral obstruction in 9 (2%) and ureteral necrosis in 1 patient (0.23%). All complications occurred during the 6-month postoperative period and after re-operation or conservative management no graft or patient was lost due to urological complications.
CONCLUSIONS
The quoted overall rate of urological complications varies from 2.9 to 12.5%; our complication rate was 4.23%. This relatively low rate is probably due to the Woodruff ureteroneocystostomy technique.
