Split ureteral stent after ureteroureterostomy.

ABSTRACT

Ipsilateral ureteroureterostomy is a well documented surgical approach to duplicated collecting systems associated with obstruction or Vesicoureteral reflux. Indwelling stents are employed in these procedures, to facilitate unobstructed flow across the anastomosis, to minimize anastomotic leak, and to assist in aligning the repair. Positioning of the ureteral stent is controversial. Some advocate placement of the stent to the recipient ureter across the suture line to prevent anastomotic stricture. Others prefer placing the stent along the donor ureter in order to facilitate drainage of the moiety that was originally obstructed. We describe a technique that allows drainage both ureters by using a single stent that has been split at its proximal end just across the U-U anastomosis.
