Clinical Report: Efficacy of Combined Midurethral Sling and Anterior Colporrhaphy for SUI with Cystocele

Overview

This systematic review and single-arm meta-analysis evaluates the effectiveness of combining midurethral sling (MUS) and anterior colporrhaphy (AC) in treating stress urinary incontinence (SUI) associated with cystocele. The pooled data suggest a high cure rate for SUI and cystocele repair with this combined surgical approach.

Background

Stress urinary incontinence (SUI) is the most common type of urinary incontinence, often caused by intrinsic sphincter deficiency or urethral hypermobility. It frequently coexists with pelvic organ prolapse (POP), particularly anterior vaginal wall prolapse (cystocele). Surgical repair of both conditions simultaneously is desirable to reduce anesthesia risk and recovery time. The midurethral sling is the standard treatment for SUI, while anterior colporrhaphy is commonly used for cystocele repair, though recurrence rates remain significant. Combining MUS with AC may improve outcomes by addressing both urethral support and anterior vaginal wall laxity.

Data Highlights

The systematic review included studies from 2001 to June 2024, focusing on female patients with SUI and grade 1–3 cystocele undergoing combined MUS and AC. Cure rates for SUI varied widely across studies, ranging from 80.5% to 97%. The review aimed to pool these data to provide a more precise estimate of efficacy. Postoperative complications and cystocele recurrence rates were also assessed, though specific numerical data were not provided in the excerpt.

Key Findings

• Stress urinary incontinence frequently coexists with cystocele, with up to 63% of SUI patients having POP and 55% of POP patients having SUI.
• Midurethral sling (MUS) is the standard surgical treatment for SUI, while anterior colporrhaphy (AC) is the most common procedure for cystocele repair.
• Recurrence rates after AC alone can be as high as 40% or more for anterior vaginal prolapse.
• Combining MUS with AC addresses both urethral hypermobility and anterior vaginal wall laxity, potentially improving cure rates for SUI associated with cystocele.
• Reported cure rates for the combined procedure vary widely, from 80.5% to 97%, indicating the need for pooled analysis to clarify efficacy.
• The systematic review followed PRISMA guidelines and included studies with female patients having grade 1–3 cystocele treated with MUS and AC, excluding more complex cases and other interventions.

Clinical Implications

Clinicians should consider the combined use of midurethral sling and anterior colporrhaphy for patients presenting with SUI and concomitant cystocele to optimize surgical outcomes. This approach may reduce recurrence rates and improve quality of life by addressing both urethral support and anterior vaginal wall defects in a single procedure. Careful patient selection and adherence to standardized surgical techniques are essential to maximize benefits and minimize complications.

Conclusion

The combined surgical approach of midurethral sling and anterior colporrhaphy demonstrates promising efficacy in treating stress urinary incontinence associated with cystocele. Further high-quality studies are warranted to confirm these findings and guide clinical practice.
