Subtrigonal Inlay Patch Technique with Buccal Mucosa Graft for Recurrent Bladder Neck Contractures

Introduction: We aimed to present a novel subtrigonal inlay patch (SIP) technique with buccal mucosa graft (BMG) for recurrent bladder neck contracture (BNC) via open approach. Materials and Methods: Surgical approach for SIP technique is described in detail and outcomes of patients who have been operated with this technique for recurrent BNC were given. Briefly, bladder neck incision is performed after vertical cystotomy, fibrotic scar tissue is excised completely, and a BMG is patched at the end. Results: All 3 patients were able to void in their first attempt after catheter removal. Follow-up durations were 14, 11, and 5 months for the patients and all 3 patients reported satisfactory voiding. No de novo urinary incontinence was reported by patients after catheter removal, and all were continent with no pad need on their last follow-up visit. None of the operated patients needed any intervention such as catheterization, dilatation, or internal urethrotomy for BNC on follow-up. Conclusion: The present study demonstrates the feasibility and promising results of SIP technique with open surgical approach. Further experience is mandatory with larger patient cohorts and longer follow-up.
