Transurethral Incision with Transverse Mucosal Realignment for the Management of Bladder Neck Contracture and Vesicourethral Anastomotic Stenosis

OBJECTIVE To assess efficacy and safety of a novel cystoscopic technique for definitive repair of bladder neck contracture (BNC) and vesicourethral anastomotic stenosis (VUAS). METHODS A retrospective review of patients who underwent a transurethral incision with transverse mucosal realignment between July 2019 and December 2020 by a single surgeon was completed. This is novel procedure of incising a scar cystoscopically and using a laparoscopic suturing device transurethrally to bring healthy bladder mucosa across the defect, like a YV plasty. Patients were only included if they had >= 4 months follow-up. Surgical success was defined as ability to pass a 17 French flexible cystoscope through the previously stenotic segment at 4 month follow up. RESULTS Nineteen patients with a median follow-up of 6 months were included in this analysis. Etiology of posterior urethral stenosis was 53% from VUAS and 47% from BNC, with 32% of patients having prior pelvic radiation. Success was achieved in 89% of patients after 1 procedure and 100% of patients achieved success after a second procedure. There was no de novo incontinence or major complications. CONCLUSION Transurethral incision with transverse mucosal realignment for VUAS and BNC has a high success rate after only 1 procedure. This is the first reported series of an endoscopic Y-V plasty type repair for BNC and VUAS. Longer term follow up to ensure durability and reporting from other institutions will be needed to establish reproducibility. (C) 2021 Elsevier Inc.
