Randomized Trial of Retropubic Versus Single-incision Mid-Urethral Sling (Altis ) for Concomitant Management of Stress Urinary Incontinence During Native Tissue Vaginal Repair
In Brief
A clinical study evaluating RP sling placement and SIS placement for Stress Urinary Incontinence and Pelvic Floor Disorders. Completed, enrolled 280 participants across 6 sites.
Detailed Summary
One in five women will undergo prolapse surgery in their lifetime, and there is a strong correlation between prolapse and urinary incontinence. Pelvic floor surgeons aspire to improve relevant quality of life outcomes for women with pelvic floor disorders while minimizing complications and unnecessary procedures. There has been an experience of disappointment and frustration when a patient returns following POP repair with new symptoms of Stress Urinary Incontinence (SUI) that she ranks as a greater disruption to her quality of life than her original vaginal bulge. While retropubic (RP) slings are considered to be the "gold-standard" referent for other slings with long-term outcomes data, they are associated with the highest risks of intra- and post-operative complications including bladder injury, bleeding, and post-operative voiding dysfunction. Single-incision slings (SIS) are the latest iteration in sling development that build upon the benefits of slings but avoid passage through the muscles of the inner thigh. The hypothesis for this study is that single-incision slings (Altis) are non-inferior to Retropubic mid-urethral slings when placed at the time of native tissue vaginal repair.

Timeline
Interventions
A 1.5 cm incision will be made at the mid-urethra through a separate vaginal incision with lateral dissection with Metzembaum scissors. After placement of both trocars, cystoscopy with a 70-degree scope will be performed to assess for bladder and urethral injury. Surgeons will set the tension of the tension-free vaginal tape (TVT) slings so that a spacer can be placed between the sling and the urethra. Sling tensioning will be performed after anterior and apical prolapse is corrected.
The sling is introduced through a single anterior vaginal incision of 1.5 cm at the mid-urethra. The sling/needle assembly is advanced behind the ischiopubic rami in a transobturator trajectory toward the obturator space bilaterally. The needle is then removed by simply sliding the fixating tip back out. The other side is then completed in an identical fashion. After the fixation of the two anchors at the 2 and 10 o'clock positions, the patient's bladder is filled with 250 mL of Sodium Chloride (NaCl). Afterward, an intraoperative crede maneuver is performed and the tension adjustment suture is pulled, when necessary, to achieve the desired continence. The mesh will lie in direct apposition to the urethra. The adjustment thread is then cut short and the vaginal incision is closed with an absorbable suture.
