Percutaneous nephrouretero lithotripsy (PNL) is being rapidly popularized as a form of lithotomy for upper urinary tract lithiasis. Ths most important element in lithotripsy is the ultrasound lithotriptor (USL), but development of a more effective USL has been long-needed. We report here the results of treating 30 cases of upper urinary tract lithiasis using a newly developed USL (SUS-501). Our subjects consisted of 20 patients with nephrolithiasis and 10 patients with ureterolithiasis. Using this device, complete lithotripsy was achieved in 75% of the patients with nephorolithiasis and in 100% of those with ureterolithiasis, of 87% of the total patients, with a mean number of 1.6 operations and mean duration of operation of 20 min. Urinary flow was improved even in cases of incomplete lithotripsy. It was shown in the present study that the time required for lithotripsy can be shortened by the use of this device. PNL using this device resulted in a satisfactory rate of lithotripsy and a shorter duration of treatment without side efffects.
