Objective:To observe the effect of acupuncture on the urodynamics of bladder dysfunction in patients with radial hysterectomy.Methods: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(Qave)of urine were detected after seven days' treatment.Results:On the 7th day after operation

no significant differences were found among 3 groups in PVR

MCC and Qave.On the 12 th day

PVR of 3 groups decreased significantly(P<0.05)and Qave of SP6 and Baliao groups increased considerably(P<0.05).In comparison with control group

PVR of SP6 and Baliao groups decreased considerably

while Qave 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.Conclusion: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.
