Objective To investigate the quality of life (QoL) and sexuality in women affected by pelvic organ prolapse (POP) and treated by bilateral sacrospinous ligament fixation (SSLF) with vaginal hysterectomy. Methods This is a prospective observational study carried out at Isparta City Hospital from July 2017 to December 2018. A total of 26 sexually active women with symptomatic uterine prolapse POP-Q (Pelvic Organ Prolapse Quantification) stage II or higher requiring surgery were included in the study. Short Form Health Survey (SF-36) was used preoperatively and at 6 months to examine the impacts of vaginal reconstruction on QoL. To assess sexual functioning, the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) was used preoperatively and at 6 months. Results A significant improvement of POP-Q landmarks was found between pre- and posttreatment at 6 months of follow-up. The patients reported QoL improvement at the follow-up for all the categories of physical functioning, bodily pain, physical health, general health, vitality, social activity, emotional state, and mental health with respect to the baseline values (P < .001). The results of PISQ-12 demonstrated a significant improvement for all the three fields: behavioral emotive factor, physical factor, and partner-related factor, and the total score at 6 months after surgery (P < .001). Conclusion This study clearly demonstrates that bilateral SSLF is able to significantly improve both QoL and sexual function in patients with POP. Improvement in sexuality and QoL after surgery may be explained by correction of avoidance of sexual intercourse due to prolapse and physical recovery.
