A parallel incision, unstented extravesical ureteroneocystostomy was used in 203 human kidney transplants. The reoperation rate was 1 per cent. Extravasation of urine occurred in 3 patients, 1 of whom required surgical repair. One patient required transurethral fulguration of a ureteral bleeder. Two patients had grade 1 reflux and none required repair. No patient had ureteral obstruction of the anastomosis. This simple technique is useful because ureteral length and bladder dissection are minimal, and no separate cystotomy is required. The adequacy of the submucosal tunnel is judged when the ureter is passed through it.
