OBJECTIVE: Evaluation of the use of defunctionalized bladder in renal transplantation, concerning surgical complications. METHODS: In order to assess the complication rate of ureteral reimplantation in long-term defunctionalized bladder, we compared 20 patients on haemodialysis for more than 15 years (group I) with another 20 patients on haemodialysis for less than 5 years (group II). None of these patients had renal failure due to urological causes or neurogenic bladder. Non-stented extravesical ureteroneocystostomy was done routinely in all patients except 1 in group II who underwent Politano-Leadbetter ureteroneocystostomy and 7 patients in group I who underwent Politano-Leadbetter (3 patients) and pyelo-ureteral anastomosis using the recipient's native ureter (4 patients). The amount of residual urine was insignificant (<100 cm(3)) in both groups. RESULTS: The mean postoperative bladder catheterization period was 7.8 days in group I and 4.2 days in group II. Postoperative urinary tract infections were observed in 9 cases of group I and in 4 cases of group II. No surgical complications occurred in patients of group II, while there were 6 patients with surgical complications in group I: stenosis after a pyelo-ureteral anastomosis (1 case), stenosis after a ureterovesical anastomosis with Politano-Leadbetter technique (1 case), urinary fistulae (3 cases; 1 with Politano-Leadbetter ureteroneocystostomy and 2 cases with pyelo-ureteral anastomosis), and vesico-ureteral reflux (1 case with Politano-Leadbetter ureteroneocystostomy). These 6 cases had the lowest bladder capacity (30-150 cm(3)) among our 40 patients. Graft losses were comparable between the two groups and were not due to surgical complications. CONCLUSION: Small defunctionalized bladders can be used in kidney transplantation, but it may represent an increased surgical risk due to difficulty in performing ureteral reimplantation.
