Purpose

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.

Masking Description
Participants and will be masked during the one-year follow-up period.Precautions will be taken to minimize unmasking the study groups: Since RP slings require two suprapubic stab incisions, identical sham incision will also be performed in the SIS group.

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
RP sling group
Participants assigned to the retropubic (RP) sling group will have the RP sling placement procedure.
  • Device: RP sling placement
    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.
Experimental
SIS group
Participants assigned to the single-incision sling (SIS) group will have the SIS placement procedure.
  • Device: SIS placement
    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.

Detailed Description

Pelvic floor surgeons aspire to improve relevant quality of life outcomes for women with pelvic floor disorders while minimizing complications and unnecessary procedures. Efficacy and risk always compete for equilibrium. Level I evidence has demonstrated a positive efficacy benefit of a concomitant synthetic mid-urethral sling in women with, and without, pre-operative symptoms of SUI who are undergoing POP repair. Concomitant sling placement has been shown to reduce the risk of de novo or persistent SUI from 50% to 23%. The combination of surgical treatment of POP and SUI at the same time, however, increases the risk of incomplete bladder emptying. 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. As the combination of POP and sling surgery increases the risk of voiding dysfunction, and rates of incomplete bladder emptying appear significantly lower for SIS than RP slings, the study team hypothesizes that the use of the Single-incision Mid-Urethral Sling SIS will be non-inferior to RP slings in efficacy and superior in irritative voiding symptoms/voiding dysfunction at one year after combined surgery.
