Abstract: ObjectiveTo investigate the effective approach for the treatment of detrusor underactivity. Methods98 patients with detrusor underactivity were randomly divided into electrotherapy group (electroacupuncture, interference current stimulation, n=32), medicine group (n=32) and electrotherapy-medicine group (n=34). The patients were assessed with examination of urodynamics and clinical parameters before and after treatment. ResultsThe detrusor strength were stronger after treatment in all the 3 groups (P<0.001), but electrotherapy-medicine group was more stronger than the other 2 groups (P<0.01). The cure rate in the 3 groups were 68.75%, 59.38% and 88.23% respectively, the patients in electrotherapy-medicine group gained significantly better results than the other 2 groups (x²=9.976, P<0.01). The difference of cure rate between the electrotherapy group and the medicine group was not significant (P>0.05). ConclusionElectric stimulation therapy combined with medicine is an effective intervention for treatment of detrusor underactivity and is better than electric stimulation therapy or drugs only.
