We prospectively randomized total 29 patients with renal stones into two groups between Aug 2014 and March 2016. The US group was treated using a ultrasonic lithotripter (Swiss LithoClast® Master) and the PN group was treated with a pneumatic lithotripter (Swiss LithoClast® ). We compared treatment outcomes in these groups. The US group consisted of 17 patients and the PN group 12 patients. There was no significant difference between the groups in baseline characteristics (age, sex, body mass index, side, stone size, and density). There was no significant difference in total operative time (p＝0.63), stone-free rate (p＝ 0.19), hemoglobin deficit (p＝0.49), or rate of postoperative sepsis (p＝0.99) between the two groups. However, intracorporal stone disintegration and removal time was significantly shorter in the US group than the PN group (p＝0.029). These results suggest that the ultrasonic lithotripter can be superior to the existing pneumatic lithotripter in saving intracorporal stone disintegration and removal time in percutaneous nephrolithotomy.
