Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

SASS (Single-incision Versus Retropubic Mid-Urethral Sling (Solyx) for SUI During Minimally Invasive Sacrocolpopexy) will be a multicenter, prospective, randomized, single-blind non-inferiority trial.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

SASS aims to compare the efficacy of a single-incision (SIS) versus a retropubic mid-urethral sling (RP) placed at the time of minimally invasive sacrocolpopexy in women with pelvic organ prolapse and objectively confirmed stress urinary incontinence (SUI).

SINGLE

Participants
Participants will be masked during the five-year follow-up period. Precautions will be taken to minimize unmasking the study groups. Since RP (retropubic) slings require two suprapubic stab incisions, identical sham incision will also be performed in the SIS (Single-Incision Sling) group.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

RP Sling Group

Participants assigned to the retropubic (RP) sling group will have the RP sling placement procedure
