Introduction and hypothesis: Surgery for pelvic organ prolapse (POP) has high recurrence rates. Long-term anatomical and patient-reported outcomes after pelvic floor repair are therefore required.
Methods: This prospective observational cohort study was conducted in a teaching hospital with tertiary referral function for patients with POP. Patients with symptomatic vaginal vault or uterine prolapse (simplified POP Quantification [sPOPQ] stage ≥2), who underwent robot-assisted sacrocolpopexy (RASC) or supracervical hysterectomy with sacrocervicopexy (RSHS), were included. Follow-up visits with sPOPQ evaluations were planned 4 years after surgery. Patients received pre- and postoperative questionnaires reporting symptoms of vaginal bulge, Urogenital Distress Inventory (UDI-6), and Pelvic Floor Impact Questionnaire (PFIQ-7). Primary outcome was patient self-reported symptoms. Secondary outcome was anatomical cure (sPOPQ stage 1) for all vaginal compartments.
Results: Seventy-seven patients were included. Sixty-one patients (79%) were evaluated after 50 months (physical examination n = 51). Symptoms of bulge (95% vs 15% p ˂ 0.0005), median UDI-6 scores (26.7 vs 22.2, p = 0.048), median PFIQ-7 scores (60.0 vs 0, p = 0.008), and median sPOPQ stages in all landmarks improved significantly from the pre- to the postoperative visit. Thirty patients (59%) were completely recurrence free and 96% of patients had no apical recurrence. Most recurrences were asymptomatic cystoceles (20%). There was one surgical re-intervention for recurrent prolapse (1.6%).
Conclusions: Robot-assisted sacrocolpopexy and RSHS show sustainable results in the treatment of prolapse. Symptoms of bulge, urinary symptoms, and quality of life improved substantially 50 months postoperatively. Patients should be counseled about the risk of anterior wall recurrence and the small chance of recurrent symptoms that need treatment.
