Comparison of Efficacy Between YAG laser Lithotripsy and Extracorporeal Shock Wave Lithotripsy for Ureteral Stones

Objective To investigate the clinical efficacy of YAG laser lithotripsy and extracorporeal shock wave lithotripsy for ureteral stones. Methods 300 patients with ureteral stones admitted to our hospital were selected and randomly divided into control group and observation group with 150 in each group. Extracorporeal Shock Wave Lithotripsy was used in the control group, while YAG laser lithotripsy was performed in the observation group. The clinical effect and incidence of complications of the two groups were observed. Results The operation time of the observation group was obviously shorter than that of the control group; Clearance rate of the stones(diameter1 cm) of the observation group was higher than that of the control group, and the difference was statistically significant(P0.05); The difference of clearance rate of the stones(diameter ﹤ 1 cm) between the two groups was not obvious and statistically significant(P ﹥ 0.05); The difference of clearance rate of upper ureteral stones between the two groups was not obvious and statistically significant(P﹥0.05); The difference of clearance rate of middle-lower ureteral stones between the two groups was obvious and statistically significant(P0.05).The difference between the incidence of complications of the two groups was not obvious and statistically significant(P﹥0.05).Conclusion For patients with ureteral stones, two therapeutic schemes have their advantages and disadvantages, should be a reasonable choice according to the condition of. If the stone is located in the upper and the diameter below 1cm, can take the extracorporeal shock wave lithotripsy; if the stones located in the lower section and more than 1cm in diameter, recommended ureteroscopic holmium laser lithotripsy.
