ObjectiveTo evaluate the efficacy of Paishi decoction in ureteral calculi treatment.

MethodsUreteral calculi patients were voluntarily divided into two groups in Shanghai Baoshan Traditional Chinese Medicine-Integrated Hospital. Patients in the control group received anti-inflammatory symptomatic treatment for 2 weeks， and patients in the treatment group received anti-inflammatory symptomatic treatment combined with Paishi decoction for 2 weeks.

ResultsThere was no significant difference between the two groups in gender， age， body weight and stone size. Compared with the control group， after taking Paishi decoction for 2 weeks， the urinary oxalic acid and calcium in the treatment group decreased significantly， and the urine citric acid increased （P<0.05）. The difference in clinical effective rate was significant between the two groups （P<0.05）.

ConclusionPaishi decoction is superior to single anti-inflammatory symptomatic treatment in the treatment of ureteral calculi， which reflects the advantages of integrated traditional Chinese and Western medicine. However， the number of patients included in this study was limited， further studies are in need to verify the result.
