Introduction: we investigated the clinicopathologic features, method of treatment, and complications related to the conservative treatment and surgical treatment of patients with pelvic organ prolapse (POP).

Methods: we retrospectively analyzed 288 patients who were diagnosed with POP from January 2007 to December 2017. The patients were divided into two groups according to the treatment method (Group A received conservative treatment and Group B received surgical treatment). The patients' clinicopathologic characteristics, treatment method, and post-treatment complications were compared between Groups A and B.

Results: of the total 288 patients, 83 and 205 patients were assigned to Groups A and B, respectively. The most common symptom was a bearing-down sensation (n = 205, 71.2%), which was reported in 51 (61.4%) and 154 (75.1%) patients from Groups A and B, respectively. Among underlying diseases, hypertension was the most common in both groups (40 and 102 patients in Groups A and B, respectively). Overall, 205 patients underwent surgery, 23 underwent vaginal pessary, and 60 performed pelvic floor muscle exercises. The incidence of treatment-related complications was not significantly different between Groups A and B (13.3% vs. 17.6%, p = 0.37). Perioperative complications were noted in 20 (17.8%) patients and vault prolapse requiring subsequent surgery was noted in 16 (14.1%) patients.

Conclusion: as surgical treatment is associated with recurrence and complications, conservative treatment methods can be initially considered for patients with POP. In this study, there was no difference in the incidence of complications between surgical and conservative treatments. Thus, if required, surgical treatment can be safely performed in patients with POP.
