The authors analyse the results of treatment of 28 patients with Peyronie's disease using extracorporeal shock-wave lithotripsy (ESWL) performed on Dornier U15 lithotriptor. A total of 2-6 sessions were made, maximal number--12. The efficacy was controlled by clinical indices and ultrasonic investigation (Doppler mapping of the blood flow). ESWL proved to be efficient in the treatment of Peyronie's disease (PD), primarily, in patients with early disease before appearance of severe fibroplastic alterations. Less plaque vascularization by energetic Doppler mapping due to ESWL is an important diagnostic criterion of PD treatment efficacy. Conservative treatment is not indicated in marked deformities and plaque calcification, erectile dysfunction. Moreover, any injection into the tunica albuginea, especially complicated by hematomas may be a damaging factor which triggers fibrous inflammation. Such patients should be treated surgically. If the patient is interested in immediate results or is not interested in continuation of sexual life, the treatment is prognostically uneffective. Thus, ESWL is an effective, safe method of PD treatment but requires further study and accumulation of clinical experience.
