Objective:To evaluate the short-term efficacy of pelvic magnetic stimulation combined with pelvic muscle biofeedback on female Idiopathic Overactive Bladder (IOAB).Methods:96 cases of IOAB females were randomly divided into control group (magnetic stimulation treatment n=48) and observation group (magnetic stimulation with biofeedback n=48). All the patients were dealt with the sacralneuromagnetic stimulation (once, qod), with 5 times in total. Then the patients in observation group were processed with biofeedback (10 times). Overactive Bladder Symptom Score (OABSS), Patients Perception Bladder Condition (PPBC) and Incontinence Quality of Life Scale (I-QOL) were evaluated as the indexes.Results:The effective rate of control group and observation group respectively were 89.58% and 93.75%. There were significant differences (P=0.67). The OABSS and PPBC of two groups were decreased, I-QOL were increased after treatment (P<0.05). Difference was statistically significant in OABSS three months after treatment between the two groups (P=0.00).The recurrence rate of three months after treatment of the two groups were 18.75% and 6.38% (P=0.04).Conclusions:Both magnetic stimulation alone and magnetic stimulation with biofeedback were effective and safe in female patients with IOAB. Magnetic stimulation with biofeedback may reduce the recurrence rate and continue to improve the symptoms in a certain extent.
