About

Autologous transobturator sling placement is associated with excellent short-term results and can be performed on an outpatient basis in most cases, so long-term outcomes needs to be verified.

Full description

Stress urinary incontinence (SUI) is defined as involuntary passage of urine with rising intra-abdominal pressure. SUI is a common problem affecting 18-26.4% of women.

Over the last two decades, SUI treatment has shifted to a mid-urethral sling (MUS) or a mesh-based bladder neck procedure. Although the surgery was believed to be relatively safe, there has been a steep rise in the number of reported cases of their erosion into the lower urinary tract. Several options outside of synthetic mid-urethral sling placement exist, such as the autologous pubovaginal sling, biologic grafts, or urethral bulking agent injection. Each has its limitations, whether related to morbidity or efficacy.

The autologous slings most commonly used are the fascia lata and the rectus fascia, and they are placed at the urethra-vesical junction through the 'retropubic' approach. In an attempt to present the benefits of a "transobturator" surgical approach and avoiding risks associated with synthetic sling material, Linder and Elliott, 6performed a novel technique for autologous urethral sling placement via a" trans obturator" approach for managing female SUI.

Autologous transobturator sling placement is associated with excellent short-term results and can be performed on an outpatient basis in most cases. Notably, no patients had post-operative voiding dysfunction that necessitated sling release, and there were no major (Clavien III-V) complications.The aim of this study is to report long-term transobturator sling outcomes using autologous rectus fascia for SUI in women.

Autologous rectus Fascia TOT

Experimental group

Description:

A sterile Foley catheter is placed to drain the bladder, following this, injectable normal saline is utilized using 10 cc syringe for hydro-distention of the anterior vaginal wall, and a midline incision is made based on the mid-urethra. Dissection is carried out bilaterally to the obturator Foramen on both sides. Through Pfannestiel incision, \~1 cm× \~5 cm rectus fascia strip is isolated from the anterior rectus sheath. Two stay sutures are secured to the corner of the fascial segment on each side. Next, two separate trocar passages are performed on each side using a reusable C-shaped trocar, with care taken to ensure at least a 1 cm tissue bridge in the obturator membrane between the superior and inferior passes. Following this, the stay sutures are tied external to the obturator membrane on both sides, leaving the sling secured and flush with the mid-urethra. Sutures are also placed to secure the sling to the periurethral tissue to prevent rolling or migration
