Abstract：Objective To evaluate the efficacy of the fifth-generation EMS pneumatic lithotripsy combined with ultrasound adsorption gravel and clearance technology in the treatment of pediatric bladder stones.Methods The clinical data on 27 patients (treatment group) with bladder stones treated with the fifth-generation EMS pneumatic lithotripsy combined with ultrasound adsorption gravel and clearance technology were compared with those on another 25 cases (control) treated with pneumatic lithotripsy under a transurethral ureteroscope.Results In the treatment group, the gravel stone extraction time was (15±3) min, average operative time (20±10) min, and postoperative hospital stay (6±1) days. There was no urethral injury or residual stones. In control group, the stone extraction time was (40±6) min, mean operative time (45±15) min, and postoperative hospital stay (9±2) days. Four of the patients suffered from urethral injury, six from residual stones, and three received a second surgery .There was significant difference between the two groups (P<0.05).Conclusions The ultrasound guided fifth- generation minimally invasive percutaneous EMS pneumatic lithotripsy combined with ultrasound adsorption gravel and clearance technology is suitable for treatment of pediatric bladder stones. This approach has the advantages of minimal invasion, high efficiency, safety, reliability, simple operation, short operation, no stone residuals , quick recovery and no urethral injuries. It is superior to transurethral surgery and should be used more widely.
