Comparing two methods to predict urinary incontinence after pelvic surgery

CREDE Study: Intraoperative Crede Manoeuver Compared to Preoperative Prolapse Reduction Stress Test to Predict Postoperative de Novo Stress Urinary Incontinence (PONSUI) at the Time of Pelvic Organ Prolapse (POP) Surgery

Not applicable Interventional McGill University Health Centre/Research Institute of the McGill University Health Centre · NCT04087642

What this trial studies

The CREDE pilot study aims to compare the effectiveness of the intraoperative Crede maneuver against the preoperative prolapse reduction cough stress test in predicting postoperative de novo stress urinary incontinence (PONSUI) in women undergoing pelvic organ prolapse surgery. This randomized study will assess the rates of PONSUI and its impact on patient-reported outcomes and quality of life at 6 weeks and 6 months post-surgery. The study will also evaluate the feasibility of conducting a larger trial by validating instruments and randomization processes.

Who should consider this trial

Good fit: Ideal candidates are women with anterior, uterine, or apical prolapse requiring surgical correction, who do not have a history of stress urinary incontinence.

Not a fit: Patients with a history of stress urinary incontinence, previous anti-incontinence surgery, or isolated posterior compartment prolapse may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the prediction and prevention of urinary incontinence in women undergoing pelvic surgery, enhancing their quality of life.

How similar studies have performed: While this approach is novel in its specific comparison, similar studies have shown promise in predicting urinary incontinence outcomes in pelvic surgeries.
