[Effect of acupuncture on bladder function in patients with radical hysterectomy]

To observe the effect of acupuncture on the urodynamics of bladder dysfunction in patients with radial hysterectomy.

A total of 64 cases of bladder dysfunction patients with radial hysterectomy were divided into urinary canal indwelling group (control group, 19 cases), Sanyinjiao (SP 6) group (23 cases) and Baliao (bilateral BL 31, BL 32, BL 33 and BL 34) group (22 cases). EA (4 Hz, 4-6 V) was applied to the abovementioned acupoints for 30 min, once daily. Catheters were replaced on the 7th day after surgical operation in all the patients and then removed after 5 days' treatment. Postvoid residual urine volume (PVR), maximum cystometric capacity (MCC), and average flow rate (Q(ave)) of urine were detected after seven days' treatment.

On the 7th day after operation, no significant differences were found among 3 groups in PVR, MCC and Q(ave). On the 12th day, PVR of 3 groups decreased significantly (P < 0.05) and Q(ave) of SP6 and Baliao groups increased considerably (P < 0.05). In comparison with control group, PVR of SP6 and Baliao groups decreased considerably, while Q(ave) of the two acupuncture groups increased significantly (P < 0.05), and the therapeutic effects of Baliao group were obviously superior to those of SP6 group (P < 0.05). Of the 19, 23 and 22 patients with urinary canal indwelling in control, SP6 and Baliao groups, 16 (84.21%), 18 (78.26%) and 7 (31.82%) had no marked improvement in the bladder function on the 12th day after operation. On the 7th and 12th day after operation, the urinary tract infection was found in 1 and 10 cases in control group, 2 and 8 cases in SP6 group, and 2 and 6 cases in Baliao group respectively.

Acupuncture has a good therapeutic effect in improving the urodynamics of the bladder in radial hysterectomy patients, and the action of Baliao is the best.
