After prior rectocele and cystocele repair, I now have stage 3 vaginal vault prolapse and am scheduled for sacrocolpopexy; what bladder evaluation and precautions should I consider?

Bladder Evaluation Before Sacrocolpopexy for Stage 3 Vaginal Vault Prolapse

You should undergo stress testing with prolapse reduction before your sacrocolpopexy to evaluate for occult stress urinary incontinence, and your surgeon may consider multichannel urodynamic studies (UDS) to assess for detrusor dysfunction and predict postoperative bladder function. 1

Why Bladder Testing Matters in Your Situation

Your concern about bladder function is well-founded. With stage 3 vault prolapse, the prolapse itself may be masking stress urinary incontinence (SUI) that will become apparent once the prolapse is corrected. The AUA/SUFU guidelines specifically address this scenario:

Mandatory Evaluation: Stress Testing with Prolapse Reduction

• A significant proportion of women with high-grade prolapse without SUI symptoms will develop stress incontinence after prolapse repair 1
• Your surgeon should perform stress testing while manually reducing your prolapse (using a pessary, ring forceps, or vaginal pack) to unmask any "occult" stress incontinence
• This test is critical because finding occult SUI changes your surgical plan - you may need a concomitant anti-incontinence procedure at the time of sacrocolpopexy 1

Optional But Valuable: Multichannel Urodynamic Studies

The guidelines indicate that multichannel UDS with prolapse reduction may be performed to:

• Assess for occult stress incontinence more definitively
• Evaluate detrusor function (bladder muscle activity)
• Determine if any urinary retention you might have is due to bladder muscle weakness versus outlet obstruction
• Predict postoperative bladder function once your prolapse is surgically corrected 1

This is particularly relevant given your history of prior pelvic floor surgery (rectocele and cystocele repair), which makes you a more "complicated" patient where UDS may provide valuable information for surgical planning and counseling.

The Concomitant Anti-Incontinence Procedure Decision

If stress testing reveals occult SUI, you face an important decision:

The 2023 AUA/SUFU guidelines support consideration of a concomitant anti-incontinence procedure (typically a midurethral sling) at the time of prolapse repair 2:

• Women who undergo combined surgery have lower rates of postoperative SUI (80% complete continence rate at 22-month follow-up)
• However, combined surgery carries higher rates of voiding symptoms and complications including bladder perforation, urethral injuries, and tape exposure (28% vs 15% adverse events) 2

The alternative is a two-step approach: repair the prolapse first, then address any SUI that develops afterward with a separate procedure. This is acceptable if you are counseled about the possibility of needing a second surgery 3.

Specific Bladder-Related Risks with Sacrocolpopexy

Be aware of these bladder-related outcomes:

Postoperative Voiding Issues

• Patients with elevated post-void residual (PVR) urine volumes preoperatively are at increased risk for transient or permanent postoperative voiding difficulties 1
• Your surgeon should measure your PVR before surgery

Changes in Urinary Symptoms

• Some women develop new urgency incontinence after prolapse repair (though this is less common with combined surgery) 2
• Conversely, irritative bladder symptoms like frequency and nocturia often improve after vault prolapse correction 4

Intraoperative Bladder Injury

• Cystotomy (bladder perforation) can occur during sacrocolpopexy, particularly if a concomitant anti-incontinence procedure is performed 5
• This is typically recognized and repaired intraoperatively without long-term consequences

Common Pitfalls to Avoid

1. Don't skip the prolapse reduction stress test - proceeding to sacrocolpopexy without evaluating for occult SUI may result in postoperative stress incontinence requiring a second surgery
2. Don't assume your prior cystocele repair protects against future SUI - the vault prolapse itself changes pelvic anatomy and may unmask new incontinence
3. Ensure your surgeon discusses the trade-offs of concomitant anti-incontinence surgery versus staged procedures based on YOUR priorities (avoiding a second surgery vs. minimizing complication risk)

Bottom Line for Your Surgical Planning

Before your sacrocolpopexy, insist on:

1. Stress testing with manual prolapse reduction (non-negotiable)
2. Post-void residual measurement
3. Discussion about multichannel UDS if you have any urinary symptoms (urgency, frequency, incomplete emptying) or if the stress test results are equivocal
4. Explicit counseling about whether a concomitant anti-incontinence procedure is recommended based on your testing results, with clear discussion of the risks and benefits of combined versus staged surgery

Your history of failed prior repairs makes thorough preoperative bladder evaluation even more important to optimize your surgical outcome and quality of life.
