Low incidence of urologic complications after renal transplantation.

The incidence of urologic complications after renal transplantation has been reported to range from less than 1 to 10 percent. They are still a significant source of morbidity and mortality. We report on 111 kidney transplants performed at the San Juan Veterans Administration Hospital in 85 of whom urinary continuity was restored with a Politano-Lead-better ureteroneocystostomy, 23 with the Lich-Grégoir operation, and 3 with extravesical urinary, diversions. Important factors included meticulous attention to details during ureter manipulation, the use of prophylactic antibiotics, unabsorbable sutures in the closure of the muscular part of the bladder wall and infrequent use of drains. This resulted in a low rate of complications which included early ureteral obstruction (3.6 percent), late ureteral obstruction (1.8 percent), lithiasis (1.8 percent), urinary extravasation (0.9 percent), and ureteropelvic necrosis. No kidneys or patients were lost to technical complications, and no deep wound infections were observed. Our experience demonstrates the beneficial effects of a low complication rate on patient and graft loss.
