THE USE OF AN EXTENDED SPIRAL BLADDER FLAP FOR TREATMENT OF UPPER URETERAL LOSS

Purpose: We demonstrated the effectiveness of an extended spiral bladd er flap procedure for repair of upper ureteral injuries. Materials and Methods: Two patients with extensive ureteral loss underwent repair w ith a modified bladder flap based posterolaterally on the affected sid e, spiraled anteriorly and inferolaterally toward the contralateral bl adder base, and then anastomosed directly to the renal pelvis. Results : With this technique renal function was preserved in both patients wi thout obstruction on followup radiographs. Conclusions: Using this ext ended bladder flap technique a well Vascularized urothelial repair can be achieved for upper ureteral injury in select patients.
