Purpose: We present our initial experience with the laparoscopic Boari flap for long ureteral strictures.
Materials And Methods: Nine patients underwent a laparoscopic Boari flap procedure at our institution. Eight patients had 4 to 7 cm distal ureteral strictures on excretory urogram and retrograde pyelogram, and 1 had transitional cell carcinoma in the distal right ureter. We analyzed our intraoperative parameters with regard to operative time and intraoperative complications. The operative results assessed were hospital stay, renal function, symptomatic improvement and radiological studies. The patient with ureteral transitional cell carcinoma was excluded from analysis because ureteral stricture etiology differed from that in the other 8.
Results: Mean operative time was 156.6 minutes. Mean estimated blood loss was 124 cc. There were no intraoperative complications. Mean hospital stay was 3 days. At a mean followup of 17.6 months all patients were symptom-free and had an unobstructed ureterovesical anastomosis on followup excretory urogram. One surgical postoperative complication resolved laparoscopically.
Conclusions: The laparoscopic Boari flap is a feasible alternative surgical technique in patients with long distal ureteral strictures. Larger series with longer followup are needed to validate these results vs the standard open technique.

Background: The urinary tract is one of the most frequently involved organs in advanced non-urologic pelvic malignances. Extensive resection of ureteric organs is mandatory during a curative surgery. Urinary reconstruction after partial ureterectomy, the most challenging situation, is associated with a higher incidence of complication than cystectomy, especially when performed with laparoscopy.

Introduction: The management of ureteral strictures longer than 1-2 cm must be treated by major surgery (1, 2). The strictures located at the distal part of the ureter can be managed by a ureteral reimplantation using a psoas hitch or a Boari flap depending on its proximity to the bladder (3). Those located at the proximal ureter can be treated by a pyeloplasty (4).
