CONTRACTION
In the present study, we conducted a RCT to show the effect of postoperative ES plus biofeedback therapy on patient rehabilitation after pelvic floor reconstructive surgery. We found that patients who had undergone pelvic floor reconstructive surgery might be benefited from postoperative ES plus biofeedback therapy.Pelvic floor reconstructive surgery is the most effective and durable treatment for POP. The ESTEEM trial conducted by Sung et al. [For PFM training to be efficient, the ability to perform a correct contraction of these muscles is essential. Several previous studies have demonstrated that ES helps women identify and strengthen PFMs [Generally, the frequency of ES ranges from 2 to 75 Hz [The effect of ES treatment on PFM strength from previous studies is uncertain. Li et al. [In clinical trials, QoL has become an important outcome measure. Previously, studies have evaluated the effect of ES on QoL improvement in SUI patients. For example, Terlikowski et al. [The present study has several limitations. First, a long-term follow-up (6 months to 1 year or longer) was not performed. Long-term effect of postoperative ES plus biofeedback therapy on pelvic floor function after pelvic floor reconstructive surgery should be determined. Second, all patients in this study were come from a single-center. This may cause selection bias. Finally, we only used one tool to evaluate patient’s reported QoL. More tools or questionnaires are needed to adequately evaluate QoL improvements.In conclusion, this study demonstrated that for patients with POP who had undergone pelvic floor reconstructive surgery, postoperative ES plus biofeedback therapy could significantly improve urination function, PFM strength, and patient’s reported QoL, comparing to the conventional intervention. More RCTs with sufficient sample sizes and long-term follow-up are still needed for further study.
