['To determine the need for postoperative cystography following extravesical ureteroneocystostomy for renal transplantation.', 'The clinical courses of 200 consecutive kidney transplant recipients who underwent urinary tract reconstruction by parallel incision extravesical ureteroneocystostomy were reviewed.', 'Five of the 200 recipients did not have the study because of early mortality (1) or medical problems (4). Grade I vesicoureteral reflux was present in 5 (3%) of 182 unstented allograft ureters and 5 of 13 stented allograft ureters. Two patients (1%) underwent repeat ureteroneocystostomy, one for obstruction and one for extravasation. The cystograms were normal in both patients.'] Is postoperative cystography unnecessary following renal transplantation with parallel incision extravesical ureteroneocystostomy?
