Case report: laparoscopic Boari flap

A Boari flap may be required to bridge long defects of the middle and lower ureter to the bladder. Laparoscopic construction of a Boari flap was performed in a patient with a ureteral stricture secondary to iatrogenic injury. The salient steps performed were spatulation of the transected ureteral end, fashioning of a Boari flap from the bladder, end-to-side anastomosis of the ureter to the flap, placement of a stent with the aid of a suction cannula, and closure of the flap over the stent. A Boari flap can be accomplished laparoscopically with minimal morbidity.
