AIMS: The aim of this study was to investigate the efficacy of extracorporeal magnetic stimulation (EMS) for the treatment of bothersome and severe symptoms of stress urinary incontinence (SUI) and overactive bladder syndrome (OAB) in female patients.
MATERIAL AND METHODS: A retrospective review was conducted on patients with SUI and OAB who were referred to EMS therapy. Successful treatment for the bothersome symptoms of OAB and SUI was defined as score ≤ 1 for questions 2 and 3 on the Urodynamic Distress Inventory-6. The objective cure of SUI and OAB was defined as no urinary leakage during the cough stress test and any urgency, urge incontinence and voiding frequency of less than eight times per 24 h based on the 3-day bladder diary, after the 9 weeks of treatment, respectively.
RESULTS: Ninety-three patients with SUI or OAB underwent a 9-week course of EMS at 20 min twice weekly. Seventy-two (77%) patients completed EMS treatment. Geographical factor and poor economic status were two main factors for dropout. A total of 94.1% (32 of 34) and 86.8% (33 of 38) of subjects had successful treatment for the bothersome symptoms of OAB and SUI, respectively. In contrast, the cure rate for OAB and SUI was only 61.7% and 42.1%, respectively. There was also a significant improvement in both Urogenital Distress Inventory Short Form (bothersome on lower urinary tract symptoms) and the Incontinence Impact Questionnaire Short Form (quality of life) total score in both groups after EMS.
CONCLUSIONS: EMS is a safe and effective alternative method for treating SUI and OAB. Further studies are needed to evaluate the long-term efficacy.
