Objective: To appraise the preventive effect of transcutaneous electrical stimulation pangguangshu and sanyinjiao acupoints on urine retention caused by using morphine epidural analgesia after operation and improvement on bladder function．

Methods: 40 Rabbits were randomly divided into two groups，each group contained 20rabbits，experimental group was given transcutaneous electrical stimulation pangguangshu and sanyinjiao acupoints in the same time of every day for 4days，30minutes once time，operation on abdomen were taken on the fifth day in the condition of epidural anaesthesia，transcutaneous electrical stimulation pangguangshu and sanyinjiao acupoints was done during the operation，than applied morphine epidural analgesia，control group wasn’t given ranscutaneous electrical stimulation，only applied morphine epidural analgesia after operation，the changes of intravesical pressure，micturition threshold and residual urine volume were observed in the two groups and compared．

Results: The rabbits’ intravesical pressure in the experimental group was obviously higher than that in the control group，the micturition threshold and residual urine volume of rabbits in the experimental group were significantly lower than those in the control group rabbits．

Conclusion: Transcutaneous electrical stimulation pangguangshu and sanyinjiao acupoints could effectively reduce the inhibition function on bladder function by using morphine epidural analgesia after operation，protect and improve bladder function to prevent urine retention．
