Abstract：Objective: To explore the clinical curative effect of the fourth generation of EMS ultrasonic combined pneumatic ballistic lithotripsy clearing stone system based on percutaneous nephroscope to treat kidney stones. Methods: From Oct. 2012 to Aug. 2014, 420 cases of renal calculi were selected, subjected to percutaneous nephrolithotomy and equally divided into two groups: observation group and control group. The control group was given traditional minimally invasive percutaneous nephrolithotomy with air pressure ballistic lithotomy, and the observation group was treated with the fourth generation of EMS ultrasonic combined pneumatic ballistic lithotripsy clearing stone system. The postoperative quality of life, adverse reactions and the curative effect were compared between two groups. Results: Stone clearance rate in the observation group at stage I was 94.29% (198/210), and that in the control group was 84.76% (178/210) (t=10.15, P<0.05). There were significant difference in life satisfaction, healthy index, emotional score, the sentiment index between two groups after operation (P<0.05). There was significant difference in both two groups before and after operation (P<0.05). The incidence of postoperative local tissue injury in the observation group was 1.90% (4/210) and 6.67% (14/210) in the control group (χ2=5.80, P<5.80). There was no statistically significant difference (P>0.05) in postoperative bleeding and renal damage between the two groups. Conclusions: The fourth generation of EMS ultrasonic combined pneumatic ballistic lithotripsy clearing stone system based on percutaneous nephroscope is effective and safe in the treatment of renal stones, the incidence of postoperative adverse reaction was low, and it is worth popularizing in clinic.
