Objectives:To assess the long-term outcomes of laparoscopic promontofixation (LP) for the treatment of pelvic organ prolapse (POP). Methods: A total of 501 consecutive patients with POP were included in this prospective study. The patients' mean age was 63.23 (36-90) years, their mean body mass index was 25.14 (15-36) and their mean number of deliveries was 3.3 (0-14). A POP grade Ն3 was diagnosed in 70.4% of the patients and 38.9% of them had a history of abdominal surgery. The patients underwent a Bonney test and urodynamic study. In cases of stress urinary incontinence (SUI), the patients underwent the simultaneous insertion of a tension-free vaginal tape. A prolapse quality of life questionnaire was sent to all patients. Results: The mean operative time was 97.4 min (50-210) and there were 1.7% cases of intra-operative complications. The mean hospitalization time was 3.7 days (1-13 days). During the mean follow-up of 20.7 months (3-120), 91 (17.8%) complications were recorded , including constipation (5.5%), SUI (3.5%), vaginal erosion (2.4%), and urge incontinence (2%). Recurrences were recorded in 11.5% of the patients within an average time of 37.2 months. Risk factors for recurrence were the use of the polypropylene mesh compared with the polyester mesh (P < 0.0001), an intra-operative hysterectomy (P = 0.02), and bleeding (P = 0.049). There was a statistical significant (P < 0.001) improvement in most of the symptoms in the prolapse quality of life questionnaire. Conclusions: LP is safe with effective long-term results, with low recurrence and morbidity rates, and a good quality of life.
