Mesh-Free Versus Mesh-Based Surgery for Female Stress Urinary Incontinence: A Prospective Comparison of Pubo-Urethral Ligament Plication and Transobturator Tape

Overview

This prospective clinical study aims to compare the short-term effectiveness, safety, and patient-reported outcomes of two surgical techniques used for the treatment of female stress urinary incontinence (SUI): Pubo-Urethral Ligament Plication (PLP), a mesh-free native tissue repair method, and the Transobturator Tape (TOT) procedure, a commonly used mesh-based mid-urethral sling technique. The study evaluates continence improvement, perioperative and postoperative complications, operative time, hospital stay, postoperative pain, and patient satisfaction. The goal is to provide evidence on whether a mesh-free surgical option such as PLP can offer comparable outcomes to mesh-based TOT, particularly for patients seeking alternatives to synthetic materials.

This is a single-center, prospective, comparative clinical study evaluating two established surgical interventions for female stress urinary incontinence (SUI): Pubo-Urethral Ligament Plication (PLP) and Transobturator Tape (TOT). PLP is a mesh-free native tissue repair technique that reinforces pubo-urethral support by plicating the periurethral tissues. TOT, a mesh-based mid-urethral sling procedure, provides support to the urethra through the placement of a synthetic tape via the transobturator route. Eligible patients with a clinical diagnosis of SUI who elect to undergo surgical treatment will be allocated to one of the two interventions based on shared decision-making between the surgeon and the patient. The study will collect demographic data, operative parameters, perioperative complications, and short-term postoperative outcomes. Continence outcomes will be assessed using validated questionnaires such as the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), as well as objective clinical evaluation during follow-up visits. Pain levels, urinary retention, de-novo urgency, wound complications, and overall patient satisfaction will also be recorded. The primary aim of the study is to compare early continence improvement between the PLP and TOT procedures. Secondary aims include comparing perioperative and postoperative complications, operative time, postoperative pain, hospital discharge time, and patient-reported satisfaction. By directly comparing a mesh-free native tissue technique with a commonly used mesh-based sling, this study seeks to provide updated, patient-centered data that may guide surgical decision-making, especially in settings where mesh-related concerns or patient preference favor native tissue repair options.
