Extracorporeal piezoceramic Wolf lithotripter was developed in West Germany by Ziegler and Associates in collaboration with Wolf GmbH. Piezolith 2300 has no cumbersome water tube and it was constructed as a mobile unit. It requires no patient irradiation, a special room adaptation, a electrodes replacement or any auxiliary staff. From February 1988 up to May 1989 a total of 230 stones in 218 patients, 18 to 79 years old, was treated with Piezolith 2300, in our Center. Ultrasound localization failed in 7 more cases of ureteral stones. Treatment resulted quite painless. Auxiliary measures before EPL, were performed in 12 cases, only (5%). 15 pts were managed with combined procedures: ESWL + EPL, PCNL + EPL, surgery + EPL. The mean of SW was 3000 (800-6500) for each piezoelectric session. In 27 pts (12%), 4 or more EPL sessions were performed. A successful disintegration was achieved in 210 cases (90.2%). Out of 20 unsuccessful cases, 15 were managed by Dornier HM3 mod lithotripter and 4 by ULL. Post EPL ancillary procedures were required in 4 pts (1.8%). No major complications were observed in our series. At the 30-days follow-up, 57.3% of the patients were stone free. At preliminary 3-month follow-up in 120 pts the rate of the entire success raised to 75%. We think, according to others authors, that EPL is the treatment of first choice in 70% of reno-ureteral stones.
体外压电陶瓷式沃尔夫碎石机由齐格勒及其同事与德国沃尔夫有限公司合作在西德研制。Piezolith 2300没有笨重的水管，被设计成一个移动设备。它无需对患者进行辐射，无需特殊的房间改造，无需更换电极，也无需任何辅助人员。1988年2月至1989年5月，在我们中心，共有218例年龄在18至79岁的患者的230颗结石接受了Piezolith 2300治疗。另外有7例输尿管结石患者的超声定位失败。治疗过程相当无痛。仅12例（5%）患者在体外冲击波碎石术（EPL）前采取了辅助措施。15例患者采用了联合治疗方法：体外冲击波碎石术（ESWL）+体外压电陶瓷式碎石术（EPL）、经皮肾镜取石术（PCNL）+体外压电陶瓷式碎石术（EPL）、手术+体外压电陶瓷式碎石术（EPL）。每次压电治疗的平均冲击波次数为3000次（800 - 6500次）。27例（12%）患者接受了4次或更多次体外压电陶瓷式碎石术治疗。210例（90.2%）患者成功碎石。在20例未成功的病例中，15例采用多尼尔HM3型碎石机治疗，4例采用ULL治疗。4例（1.8%）患者在体外压电陶瓷式碎石术后需要辅助治疗。我们的系列研究中未观察到重大并发症。在30天的随访中，57.3%的患者结石清除。在对120例患者进行初步的3个月随访时，总体成功率提高到了75%。我们认为，根据其他作者的观点，在70%的肾输尿管结石治疗中，体外压电陶瓷式碎石术是首选治疗方法。
