Thirty-nine patients, 27 males and 12 females with renal and ureteral stones, were treated using the Modulith SL 20 between October 1990 and January 1991. Thirty-three of the 39 cases had a single session of extracorporeal shockwave lithotripsy (ESWL) and the other six cases had two sessions. The pulverization rate of ESWL by this device was 84.6%. According to the X-rays taken 21 days after ESWL, of the 37 cases, 14 (37.8%) were stone-free, 18 (48.7%) had residual sandy stones less than 4 mm in diameter, five (13.5%) had residual stone fragments larger than 4.1 mm in diameter, and two cases were not clear. Using the criterion of cases which can be expected to have spontaneous passage, in other words, residual stones less than 4 mm in diameter, lithotripsy with the Modulith SL 20 was regarded as "effective" in 32 of the 37 cases (86.5%). As side effects of this treatment, hematuria was observed for several days after ESWL in all patients, but not other serious complications were observed. Among the 37 cases in which the grade could be evaluated the evaluation for 24 (64.9%) was "useful" and that for 13 (35.1%) "useful to some extent". Therefore, ESWL was performed very successfully.
1990年10月至1991年1月期间，使用Modulith SL 20对39例肾和输尿管结石患者进行了治疗，其中男性27例，女性12例。39例患者中，33例接受了单次体外冲击波碎石术（ESWL），另外6例接受了两次治疗。该设备的ESWL碎石率为84.6%。根据ESWL后21天拍摄的X线片，37例患者中，14例（37.8%）结石清除，18例（48.7%）残留直径小于4mm的沙粒样结石，5例（13.5%）残留直径大于4.1mm的结石碎片，2例情况不明。以预期能自然排出的标准，即残留结石直径小于4mm，Modulith SL 20碎石术在37例患者中的32例（86.5%）被视为“有效”。作为该治疗的副作用，所有患者在ESWL后均出现了数天的血尿，但未观察到其他严重并发症。在可评估分级的37例患者中，24例（64.9%）的评估为“有用”，13例（35.1%）的评估为“在某种程度上有用”。因此，ESWL手术非常成功。
