Abstract
The development of ureteral obstruction or ureteral fistula formation in the renal transplant recipient usually requires surgical repair. This involves reconnecting the donor ureter to either the recipient ureter (ureteroureterostomy) or bladder (ureteroneocystostomy), or creating an anastomosis between the renal pelvis and recipient native ureter (pyeloureterostomy). Occasionally, the donor or recipient ureter is absent, necrotic or diseased so that a ureteroureterostomy, ureteroneocystostomy or pyeloureteral anastomosis cannot be performed. In 8 such cases we have performed a direct anastomosis between the donor renal pelvis and recipient bladder (pyelovesicostomy) with a followup of between 2 months and 11 years. In all 8 patients there has been no deterioration in renal function attributed to obstruction at the anastomotic site or to the free reflux between the bladder and renal pelvis. Because of the excellent short-term and long-term results of pyelovesicostomy, this procedure should be considered as an excellent alternative to pyeloureterostomy, ureteroureterostomy and ureteroneocystostomy in the reconstruction of the upper urinary tract of the renal transplant patient.
