Objective:To observe the therapeutic effect of electroacupuncture (EA) in the treatment of ureterolith patients. Methods: 121 cases of ureterolith patients were randomly divided into EA group ( n =63) and medication group ( n =58). In EA group

Shenshu (BL 23)

Pangguangshu (BL 28)

Zhongji (CV 3)

Weizhong (BL 40)

Sanyinjiao (SP 6)

Zusanli (ST 36)

Neiguan (PC 6)

etc. were punctured and stimulated electrically for 30?min. Patients of medication group were treated with intramuscular injection of Pethidine Hydroenloride(100?mg) and Anisodaminum (20 mg)

once daily. Results: After two weeks' treatment

comparison between EA group and medication group in pain relieving time (16.33±6.37 min vs 15.44±6.01 min )and analgesia maintaining time (4.60±1.42 hr vs 4.54±1.40 hr ) showed no significant difference ( P >0.05)

suggesting that both acupuncture and medication could remarkably relieve calculus induced ureteral colic. Results of ultrasonic examination or X ray film examination showed that the lithiasis removal rates of EA and medication groups were 60.32% and 43.10% respectively. Conclusion: Electroacupuncture can effectively promote the removal of ureteral calculus and reduce lithiasis induced colic in ureterolith patients.
