I now have enough information from the authoritative textbooks to give a thorough answer. Here it is:
Treatment When Uterovaginal (UV) Prolapse and Stress Urinary Incontinence (SUI) Coexist
When both conditions are present simultaneously, the management requires addressing both the prolapse and the incontinence - either with a single combined surgical procedure or staged treatment - guided by careful preoperative evaluation.
Step 1: Preoperative Evaluation
Before planning treatment, it is essential to determine whether the SUI is:
- Overt SUI - the patient already leaks with effort, and it is demonstrated clinically.
- Occult (latent) SUI - the patient appears continent, but leaks are unmasked only when the prolapse is reduced (e.g., with a pessary, packing, or manual reduction). This occurs because advanced prolapse, especially a cystocele, can kink the urethra and create a functional obstruction that masks leakage. Treating the prolapse alone relieves this kink and can paradoxically cause de novo SUI in up to 25% of women with advanced prolapse.
A reduction stress test (urodynamics with prolapse reduced) is therefore a key part of preoperative workup and guides the decision to add a concomitant incontinence procedure.
Step 2: Surgical Treatment - Combined Approach
The guiding principle is to address both conditions at the same operation when SUI (overt or occult) is confirmed.
A. Abdominal / Laparoscopic Sacrocolpopexy + Burch Colposuspension
- The landmark CARE (Colpopexy and Urinary Reduction Efforts) trial showed that performing a Burch colposuspension at the time of abdominal sacrocolpopexy significantly reduced postoperative SUI rates.
- A "universal" continence procedure at the time of sacrocolpopexy is supported for women with Stage II-IV prolapse, regardless of the preoperative reduction stress test result.
- Burch colposuspension: elevates the paravaginal tissue and bladder neck to the iliopectineal (Cooper's) ligament, restoring urethrovesical support.
B. Vaginal Prolapse Repair + Midurethral Sling (MUS)
- For vaginal approach prolapse surgery, the OPUS (Outcomes Following Vaginal Prolapse Repair and Midurethral Sling) trial showed concomitant MUS (TVT/TOT) reduced rates of de novo postoperative SUI.
- Women with overt SUI (demonstrated on exam with no contraindications) should have a concomitant sling at the time of vaginal prolapse repair.
- Women with occult SUI only - a selective approach is preferred: sling is offered if occult SUI is detected on the reduction stress test, balancing benefit against sling-specific complications (bladder perforation, voiding dysfunction, UTI, bleeding).
- When performing anterior colporrhaphy (for cystocele) with a midurethral sling, a separate incision should be made for the sling - the anterior repair should not be extended distally past the bladder neck.
C. Paravaginal Defect Repair + Sling
- Abdominal paravaginal repair corrects lateral cystocele, with SUI cure rates of 85-97%.
- If intrinsic sphincter deficiency (ISD) coexists, adding a pubovaginal sling (rectus fascial autograft) at the time of paravaginal repair improves SUI cure rates further (85% vs. 72% without sling).
Summary Table
| Surgical Route | Prolapse Procedure | Concomitant SUI Procedure |
|---|
| Abdominal / Laparoscopic | Sacrocolpopexy | Burch colposuspension (CARE trial) |
| Vaginal | Anterior colporrhaphy / apical suspension | Midurethral sling (TVT or TOT) - selective or universal per clinical findings |
| Abdominal | Paravaginal defect repair | Pubovaginal sling (especially if ISD) |
Non-Surgical Option
For women who are not fit for surgery or prefer to avoid it, a ring or shelf pessary can mechanically reduce the prolapse and simultaneously support the urethra, providing relief from both prolapse symptoms and SUI. This is first-line in elderly or medically unfit patients.
Key Clinical Points
- Up to half of all women with SUI also have POP, so screening for both at every assessment is important.
- Failure to recognize and treat prolapse at the time of SUI surgery increases the likelihood of repeat prolapse surgery (26% vs. 12% at 12 months, urologist vs. gynecologist data).
- Voiding dysfunction coexisting with SUI warrants urodynamic evaluation before surgery, as the patient must be counseled about the possibility of persistent voiding problems postoperatively.
