The use of an extended spiral bladder flap for treatment of upper ureteral loss.
OBJECTIVE
We demonstrated the effectiveness of an extended spiral bladder flap procedure for repair of upper ureteral injuries.


METHODS
Two patients with extensive ureteral loss underwent repair with a modified bladder flap based posterolaterally on the affected side, spiraled anteriorly and inferolaterally toward the contralateral bladder base, and then anastomosed directly to the renal pelvis.


RESULTS
With this technique renal function was preserved in both patients without obstruction on followup radiographs.


CONCLUSIONS
Using this extended bladder flap technique a well vascularized urothelial repair can be achieved for upper ureteral injury in select patients.
