Extended Boari-flap reconstruction in isolated tuberculous pan-ureteral stricture

A 53-year-old female presented with left loin pain and imaging showed left pan-ureteral stricture secondary to tuberculosis. The renal unit was salvaged by percutaneous nephrostomy. She was planned for ileal ureteric replacement. An extended Boari flap was constructed for her as the bladder capacity was good and Boari bladder flap reached the renal pelvis without tension. Follow-up nephrostogram revealed wide pyelovesical junction with prompt drainage. She completed antituberculous treatment. Extended Boari flap is rarely used for upper ureteric reconstruction. It should be considered as an option for complete ureteric reconstruction in the unilateral pan-ureteral stricture in selected cases.
