What this trial studies

This clinical trial investigates the effect of Tizanidine, a muscle relaxant, on postoperative urinary retention in women undergoing sacrospinous vaginal vault suspension. Postoperative urinary retention is a common complication, affecting 30-60% of patients, and can lead to the need for indwelling catheters, which are associated with discomfort and increased risk of urinary tract infections. Participants will undergo a voiding trial after surgery to assess their ability to void, and those who do not pass will be treated with Tizanidine to potentially improve their outcomes. The goal is to reduce the incidence of urinary retention and improve patient satisfaction post-surgery.

Who should consider this trial

Good fit: Ideal candidates are women undergoing sacrospinous ligament suspension for pelvic reconstructive surgery.

Not a fit: Patients with a known history of urinary retention or contraindications to Tizanidine will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the need for indwelling catheters and improve recovery experiences for patients after pelvic reconstructive surgery.

How similar studies have performed: While the use of Tizanidine for this specific purpose is novel, similar interventions targeting postoperative complications have shown promise in other studies.
