Ureteroureterostomy and pyeloureterostomy without native nephrectomy in renal transplantation.

A series of 23 patients, receiving full immunosuppression following renal transplantation, underwent a uretero- or pyelo-ureterostomy with ligation of the native ureter and no nephrectomy. In 5 patients this was carried out at the time of transplantation because of a short donor ureter and in 18 patients, at a median of 47 days after transplantation, following ureteric complications. With a median follow-up of 22 months, no complications have been seen in relation to the native kidney. Ureteroureterostomy was successful in all but 3 patients. A ureteroureterostomy without native nephrectomy is a safe and effective treatment for the management of ureteric complications following renal transplantation.
