Management of Pelvic Organ Prolapse in the Adult Congenital Genitourinary Patient

Objectives: To assess and present our experience with the management and outcomes of female pelvic organ prolapse in the adult congenital genitourinary patient population.

Methods: Retrospective review of our adult congenital GU patients with spina bifida with a documented Pelvic Organ Prolapse Quantification exam (POP-Q) from 2006 - 2021 was undertaken. Spina bifida lesion level, bladder management method, prolapse stage and component, and obstetric history were reviewed. Outcomes of treated patients are from most recent follow up.

Results: 37 congenital GU patients were identified. 26 (70%) were nulliparous with many showing advanced prolapse, defined as stage 2 or greater. By POP-Q, only 22% were stage 0, indicating no prolapse. 68% had advanced prolapse, with one case of complete procidentia despite no pregnancy history. The dominant prolapse compartment in advanced prolapse patients regardless of parity was apical, or cervical (47%). 16 had symptomatic prolapse, most with vaginal bulge or noticing bulge with catheterization. 6 patients underwent surgery with 2 vaginal hysterectomy and uterosacral suspensions and 1 sacrocolpopexy with mesh. Due to elongated cervix with protrusion, 3 patients underwent cervical shortening as their primary prolapse intervention. 4 of the patients saw a decrease in POP-Q score post-operatively with 2 patients still pending follow-up.

Conclusions: Congenital GU patients may have more advanced prolapse at younger ages and nulliparity and are frequently apical dominant. A variety of surgical options can provide meaningful improvement in the symptomatic patient.
