Assessment of Overactive Bladder after Laparoscopic Lateral Suspension for Pelvic Organ Prolapse

BACKGROUND: Pelvic organ prolapses (POP) and overactive bladder (OAB) may coexist and both negatively impact quality of life in women. The correlation between POP and OAB remains unclear, but these patients may have the OAB resolution after the surgical treatment of POP. Aim of our study was to assess the anatomical results and the effect on OAB symptoms in women who underwent laparoscopic lateral suspension for POP. MATERIALS AND METHODS: This prospective study included all women with apical POP who underwent surgical repair with laparoscopic uterine lateral suspension from January 2016 to December 2017. The baseline and the 1-year follow-up included post-void residual measurement, urinalysis, vaginal examination, OAB symptoms evaluation, and administration of questionnaires (PFDI-20, UDI 6). RESULTS: 64 women underwent laparoscopic lateral suspension for uterine prolapse and 78.1% had concomitant anterior vaginal wall defect. At 1-year follow-up the anatomic success rates were 84.4% for the apical and 76.2% for the anterior compartment. The comparison between OAB symptoms before and after the surgical procedure showed the resolution of OAB in 76% of the women, while de novo OAB was present in 2.6%. With the questionnaires 95.3% (61/64) of our patients were satisfied after the POP repair. We documented a trend in ameliorating of OAB regardless of the POP-Q stage. However, the Pearson test showed this correlation as statistically significant only in women with anterior vaginal wall defect stage III and apical stage II. No patient had vaginal exposure of the polypropylene mesh. CONCLUSION: Our data show how laparoscopic lateral suspension is an effective procedure for apical and anterior vaginal wall defects. This study provides further evidence for the concept that OAB in women with POP >II stage improves after a successful POP surgery. These women may benefit from a resolution of OAB and POP symptoms with the improvement of patient's quality of life.
