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

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.

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.

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.
