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

Area of Science:

• Urology
• Surgical Innovation

Background:

• Recurrent bladder neck contracture (BNC) presents a significant clinical challenge.
• Existing treatments for recurrent BNC often have limitations.

Purpose of the Study:

• To present a novel subtrigonal inlay patch (SIP) technique with buccal mucosa graft (BMG) for treating recurrent BNC.
• To evaluate the outcomes of this open surgical approach.

Main Methods:

• Detailed description of the surgical approach for the SIP technique.
• Excision of fibrotic scar tissue and patching with BMG.
• Open surgical approach for recurrent BNC.

Main Results:

• All three patients achieved successful voiding post-catheter removal.
• Patients reported satisfactory voiding during follow-up periods of 14, 11, and 5 months.
• No new-onset urinary incontinence or need for further intervention for BNC was observed.

Conclusions:

• The subtrigonal inlay patch (SIP) technique with buccal mucosa graft (BMG) is a feasible open surgical approach for recurrent BNC.
• The technique demonstrates promising outcomes in terms of voiding function and continence.
• Further research with larger patient cohorts and longer follow-up is warranted.
