title: Experience with pyeloureterostomy associated with simple ligation of native ureter without ipsilateral nephrectomy in renal transplantation.
abstract: Ureteroneocystostomy was used as the primary method of urinary tract reconstruction in 282 allograft renal transplants at our center since 1965. A nonrefluxing anastomosis was incorporated whenever possible. Seven patients who suffered major urological complications involving the ureteroneocystostomy required pyeloureterostomy as the method of repair using the patient's distal native ureter. No ipsilateral nephrectomy was performed and simple ligation of the native ureter with nonabsorbable suture was accomplished. Of the 7 patients 3 suffered hydronephrosis of the native kidney. None of these patients had signs or symptoms secondary to acute and chronic ureteral occlusion. Our experience suggests that intentional ligation of the native ureter during pyeloureterostomy does not result in increased morbidity to the transplant patient, and that the need for ipsilateral nephrectomy with its own added morbidity may not be necessary.
