Investigation on clinical efficacy of the fourth-generation ultrasonic lithotripsy system in the treatment of urinary tract stones

Objective To evaluate the fourth-generation ultrasonic lithotripsy system for treating the urinary tract stones. Methods 243 cases of urinary tract stones who received treatment of fourth-generation EMS ultrasonic lithotripsy system were analyzed retrospectively. Results Immediate phase I lithotrotrisy was performed successfully in 227 cases and the successful rate of phase I was 93.3% （227/243）. Delayed phase II lithotripsy was performed for 16 patients. Complications happened in 2 cases, one case occurred hydropneumothorax during operation, required in- dwelling thoracic drainage tube processing, the other had severe bleeding which conservative treatment was ineffective, cured by the intervention of super-selective renal artery embolization. Conclusion Fourth generation of ultrasonic lithotripsy for treating stones on different anatomical locations of urinary system was safe, practical and efficient, worthy of clinical application.
