OBJECTIVETo evaluate the therapeutic effect of overactive bladder after transurethral resection of prostate (TURP) preventively treated with electroacupuncture and Tolterodine.

METHODSOne hundred and twenty cases of benign prostate hyperplasia of TURP were randomly divided into an electroacupuncture and medicine group, an electroacupuncture group, a medicine group and a control group, 30 cases in each group. All the patients were treated with TURP under the continuous epidural anesthesia, and the catheter was retained for 5-7 days. In electroacupuncture group, before the surgery of the same day, Huiyang (BL 35), Ciliao (BL 32), Qugu (CV 2) and Huiyin (CV 1) were acupunctured with electroacupuncture for 30 min, once a day, 5-7 days' treatment was applied. In medicine group, Tolterodine Tartrate tablet was taken for 2 mg in the morning of surgery day, twice a day and treatment was applied for 5-7 days. In electroacupuncture and medicine group, the comprehensive therapies above in both electroacupuncture group and medicine group were applied. In control group, Pethidine of 50 mg was given by intramuscular injection when bladder was overactive, combined with Anisodamine injection of 10 mg according to the symptoms. The frequency and lasting time of bladder overactivity were compared within 72 hours after TURP in each group.

RESULTSAfter TURP, the frequency of bladder overactivity were 2-4 times a day, and lasted for 5-15 min each time in control group. The frequency and lasting time of bladder overactivity in treatment groups at different time were less than those in control group (P < 0.01, P < 0.001). There was no significant difference in comparison of frequency and lasting time of bladder overactivity between electroacupuncture and medicine group (all P > 0.05). The frequency and lasting time of bladder hyperactivity in electroacupuncture and medicine group were less than those in the electroacupuncture group and the medicine group at 24 hours, 24-48 hours, 48-72 hours after TUPR (P < 0.05, P < 0.01, P < 0.001).

CONCLUSIONAfter TURP, early prevention of combined therapy of electroacupuncture and Tolterodine with oral administration is superior to that of electroacupuncture therapy or Tolterodine for overactive bladder treatment, and it is the safe and effective method to treat overactive bladder.
