Transvaginal Diverticulum Wall Filling and Coverage Technique for Treating Female Circumferential Urethral Diverticulum

Phase 2
Not yet recruiting
Conditions
Circumferential Female Urethral Diverticulum
Registration Number
NCT07006753
Lead Sponsor
West China Hospital
Brief Summary

The goal of this clinical study is to learn if a new surgical technique called transvaginal diverticular wall filling and covering is effective and safe for treating circumferential urethral diverticulum (UD) in female patients. The main questions it aims to answer are:

Does this technique reduce the risk of postoperative complications, such as fistula formation or stress urinary incontinence (SUI)? Does it improve urinary symptoms and sexual function? What are the recurrence rates after surgery using this approach?

Researchers will follow two groups of patients:

One group includes patients who had this surgery in the past 5 years (retrospective group).

The other group includes patients who are newly treated with this technique and followed prospectively.

Participants will:

Undergo the transvaginal wall filling and covering surgery. Have regular follow-up visits to assess symptoms, complications, and quality of life.

Complete questionnaires about urinary and sexual function.

Detailed Description

Circumferential UD is a rare and complex subtype that surrounds the urethra and is associated with a higher risk of surgical complications when treated with conventional diverticulectomy. To address these challenges, this study utilizes a modified surgical approach in which the demucosalized diverticular wall is preserved, folded, and used to obliterate the diverticular cavity and reinforce the closure of the ostium. This technique aims to reduce surgical trauma, preserve urethral function, minimize dead space, and improve postoperative urinary and sexual function.

All enrolled patients will undergo this standardized surgical intervention. Follow-up assessments will be conducted at predefined timepoints (1 month and 6 months postoperatively). Evaluations will include physical examinations, symptom assessments, and validated questionnaires addressing urinary symptoms, sexual function, and overall quality of life.

Primary and secondary outcome measures include:

Improvement or resolution of UD-related symptoms (e.g., dysuria, dyspareunia, urgency) Incidence of postoperative complications (e.g., urethrovaginal fistula, de novo stress urinary incontinence) Clinical and imaging-confirmed recurrence Patient-reported outcomes regarding urinary and sexual function

This study aims to provide clinical evidence on the feasibility, safety, and potential advantages of this novel technique for managing circumferential urethral diverticulum in women.

Primary Outcome Measures
NameTimeMethod
Global Response Assessment (GRA)6 months postoperatively

Overall subjective improvement will also be documented using a 5-point Global Response Assessment (GRA) scale:

1. = Markedly worse

2. = Slightly worse

3. = No change

4. = Slightly improved

5. = Markedly improved

Recurrence Rate of Urethral Diverticulum Assessed by Clinical Symptoms6 months postoperatively

Recurrence will be assessed within 6 months postoperatively based on:

Return of typical urethral diverticulum (UD) symptoms, such as:

Post-void dribbling Dyspareunia Dysuria Recurrent urinary tract infections Palpable anterior vaginal wall mass

Urinary Continence Status Assessed by Symptom Type and Stress Test6 months postoperatively

Urinary continence status will be evaluated at 6 months postoperatively based on:

Patient-reported urinary symptoms, including the presence or absence of:

Stress urinary incontinence (SUI): involuntary leakage of urine during physical effort, sneezing, or coughing

Urgency urinary incontinence (UUI): involuntary leakage accompanied by or immediately preceded by urgency

Objective cough stress test performed in the lithotomy position with a comfortably full bladder

Patients will be classified into one of the following categories:

Continent: No symptoms of SUI or UUI and negative stress test

SUI: Symptomatic stress incontinence or positive stress test

UUI: Symptoms consistent with urgency-related leakage

Mixed urinary incontinence: Presence of both SUI and UUI symptoms

Secondary Outcome Measures

Complications6 months postoperatively
