Complications following unstented parallel incision extravesical ureteroneocystostomy in 1,000 kidney transplants.

Abstract

Between May 10, 1982 and September 1, 1990, 1,000 kidney transplant recipients underwent parallel incision extravesical ureteroneocystostomy for urinary tract reconstruction. Complications attributed to this surgical technique that required reoperation occurred in 2.1% of the recipients. These complications included urinary extravasation in 9 patients, ureteral necrosis in 3, ureteral obstruction in 3, ureteral bleeding in 3, ureteral implantation into thickened folds of peritoneum in 2 on chronic ambulatory peritoneal dialysis and ureteral implantation into an ovarian cyst in 1. Vesicoureteral reflux occurred in 0.4% of the ureteroneocystostomies, none of which was revised. No allografts were lost as a result of these complications. The principles of the technique are sound. One should be careful if the patient has a small, defunctionalized or scarred bladder, has undergone multiple pelvic operations or has had pelvic inflammatory disease.
