Objective To evaluate the effect of ureteroscopic treatment for upper urinary tract obstruction. Methods A total of 56 cases of upper urinary tract obstruction were treated under ureteroscope by using direct-vision dilatation, electrocauterization or balloon dilatation. Results A successful dilatation was achieved in 49 cases (87.5%, 49/56) whereas a failure was encountered in 7 cases. There were no complications such as ureteral perforation, rapture or heavy bleeding. A follow-up for 0.5~3 years (mean, 2.5 years) in 43 cases was carried out. The obstruction disappeared in 33 cases, remained in 6 cases, and relapsed in 4. The hydronephrosis disappeared in 30 cases, subsided in 5 cases, and had no changes in 8. Conclusions The treatment of the upper urinary tract obstruction under ureteroscope offers advantages of minimal trauma and satisfactory outcomes.

Objective To observe the therapeutic effect of Shilin Qinghua Decoction(SQD) for the treatment of urinary calculi.Methods Two hundred urinary calculi patients were equally randomized into two groups: the treatment group received SQD(mainly composed of Herba Lysimachiae,Endothelium Corneum Gigeriae Galli,Radix Paeoniae Alba,Talcum,Radix Clematidis,Poria,Semen Vaccariae,Herba Plataginis,Herba Polygoni Avicularis,Herba Dianthi,Succinum powder),and the control group received uralyt.Twenty days constituted one treatment course,and the treatment lasted 1～3 course(s) according to the illness state.The therapeutic effect was evaluated after 2 months.Results The total effective rate was 96.0% in the treatment group and 81.0% in the control group,the difference being obviously significant(P
