About this study
Official title: Improved Reconstruction Pelvic Surgery With and Without Tension-free Vaginal Tape-obturator in Women With Occult Stress Urinary Incontinence(PTOS): a Randomized Controlled Trial
- To evaluate whether a standardized tension-free vaginal tape-obturator(TVT-O) procedure, when added to a planned improved reconstruction pelvic surgery, improves the rate of urinary stress continence in subjects with occult stress incontinence.
- Observe the immediate and short-term complications, overall urinary tract function, and other aspects of pelvic health between subjects with and without a TVT-O procedure.
Read the detailed description
The primary aim of this randomized study is evaluate whether a standardized TVT-O procedure, when added to a planned improved reconstruction pelvic surgery for the treatment of pelvic organ prolapse, improves the rate of urinary stress continence in subjects with occult stress incontinence. Secondary aims include comparison of immediate and short-term complications, overall urinary tract function, and other aspects of pelvic health between subjects with and without a TVT-O procedure. The value of preoperative urodynamic testing with prolapse reduction and 1 hour pad test will also be compared between subjects with and without a concomitant TVT-O procedure.
- Being tested
- TVT-O, Improved reconstruction pelvic surgery
- Keywords
- Occult stress incontinence, Pelvic Organ Prolapse, Surgical Intervention, TVT-O(Tension-free vaginal tape-obturator), Improved Reconstructive Pelvic Surgery, Combined Surgery, Two-step Approach, Prophylactic Incontinence Procedure, Randomized Controlled Trial

Immediate and short-term complications such as hemorrhage, bladder perforation and infection.
Measured: Intraoperative and 2 years post-opeartion
