title: [The Wolf piezolith 2300: lights and shadows].
abstract: 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.
