Post-Hysterectomy Vault Prolapse With Occult Stress Incontinence
A 62-year-old G3P3 woman presents 3 years after total abdominal hysterectomy for fibroids with a 6-month history of a vaginal bulge (POP-Q: Aa -1, Ba -1, C +2, D n/a, Ap -2, Bp -2, TVL 7, GH 4, PB 3). She reports a sensation of incomplete emptying and needs digital splinting to defecate. She denies leakage with cough or activity, but on direct questioning admits to occasional loss with brisk walking since surgery, which she attributes to 'getting older.' Post-void residual is 40 mL, urinalysis is negative, and urodynamic studies show no detrusor overactivity; with the prolapse reduced, a cough stress test demonstrates leakage at 300 mL filling. She is bothered primarily by the bulge and the splinting. Comorbidities include well-controlled hypertension and a BMI of 31.
1. How should the occult stress incontinence influence your counseling and surgical plan?

This is occult (latent) stress urinary incontinence unmasked by prolapse reduction - leakage on a reduced cough stress test in a woman who denies symptoms in the unreduced state. The key judgment is that repairing the prolapse alone will likely convert occult SUI into symptomatic SUI, with reported rates of de novo postoperative SUI that are clinically meaningful.
Counseling points:
- Explain that the prolapse is currently 'kinking' the urethra and masking leakage.
- Offer a concomitant continence procedure at the time of prolapse repair (e.g., retropubic midurethral sling) rather than a staged approach, since a staged approach commits her to a second anesthetic and a period of symptomatic leakage.
- Discuss the alternative of prolapse repair alone with the understanding that she may need a later anti-incontinence operation; some patients prefer to avoid mesh and accept that risk.
- Note that a positive reduced stress test is a stronger predictor than symptoms alone; this supports offering the sling.
Document a shared decision. Also address that her defecatory splinting suggests a posterior compartment contribution that should be evaluated and addressed at the same operation.
2. She asks whether a pessary could be a reasonable first step. What is your response, and what would you monitor?

A pessary is a legitimate first-line option, but there is a specific caveat here: a space-filling pessary may relieve the bulge while unmasking or worsening stress leakage, because it holds the prolapse reduced in the same way the reduction test did. So she should be warned that her leakage may become more noticeable with the pessary in place.
Reasonable approach:
- Trial a ring or Gellhorn pessary with fitting and a follow-up visit in 1–2 weeks.
- Assess symptom relief of the bulge and the need for splinting, and specifically ask about new or worsened stress leakage.
- Review hygiene, estrogen status (topical vaginal estrogen if atrophic), and schedule interval checks for erosion or discharge.
- If the pessary relieves prolapse symptoms but produces intolerable leakage, that is useful information supporting a combined surgical approach rather than a reason to abandon pessary therapy for the prolapse itself.
A trial of a pessary does not foreclose surgery and is often the best way to clarify how much of her symptom burden is prolapse versus bladder.
3. If she elects surgery, outline the counseling you would give on route and concomitant procedures, including risks.

Given a post-hysterectomy vault prolapse with a stage 2–3 anterior/apical defect and defecatory splinting, options include:
- Vaginal native-tissue apical suspension (e.g., sacrospinous ligament fixation or uterosacral suspension) with anterior and posterior repair.
- Abdominal/robotic sacrocolpopexy with mesh, which has durable apical outcomes but greater cost and recovery.
Key counseling:
- Recurrence risk is real for any route; quote ranges rather than a single number, and note that sacrocolpopexy has somewhat lower reoperation rates for apical recurrence in many series, while vaginal approaches have shorter recovery.
- Mesh exposure risk with sacrocolpopexy (low but nonzero, higher with smoking or atrophy).
- Concomitant midurethral sling for the occult SUI, with counseling on mesh-related complications, voiding dysfunction, and the small risk of retention requiring temporary catheterization.
- De novo dyspareunia and vaginal shortening; ask about sexual activity and partner status.
- Postoperative voiding trial expectations and the possibility of transient retention.
A combined procedure addresses both the bulge and the occult leakage in one anesthetic, which is usually what the patient prefers when the tradeoffs are explained.
