Use of the Allium Round Posterior Stent for the Treatment of Recurrent Vesicourethral Anastomosis Stricture

To compare outcomes of monopolar incision and Allium Round Posterior Stent (RPS) insertion for the treatment of recurrent vesicourethral anastomosis stricture. Having a suprapubic catheter and an obstructed pattern with a peak flow rate (PFR) ≤12 mL/s on uroflowmetry were the indications for the surgery. Once the fibrotic vesicourethral anastomosis was incised, RPS was inserted at the level of vesicourethral anastomosis under fluoroscopic guidance. All the stents were removed at postoperative first year. Patients were evaluated 3months after stent removal. Objective cure was defined as no need to further treatments and PFR ≥12 mL/s while subjective cure was defined as having points
