Extracorporal Shock Wave Lithotrypsy (ESWL) is "golden" standard therapy among the various methods of treatment of urinary stone disease. We have evaluated 1645 patients with urinary stone disease who underwent ESWL from 2003 to 2006, with third generation Dornier Compact Delta lythotriptor. 932 (56.7%) of them were male and 713 (43.3%) were female, 55 (3.3%) of all were children. Patients' age varied from 1 to 93 years. The total amount of sessions performed were 3391 (mean 2.1). In case of renal calculi the amount of shocks was 2000-3500 and the duration of session varied from 20 to 35 minutes. In case of urethral calculi--3000-4500 shocks, duration of session varied from 30 to 45 minutes. From 1719 stones 1452 (84.5%) were X-Ray positive and 267 (15.5%) were X-Ray negative. ESWL was successful (stone free) in 1211 (73.6%) and semi successful in 91 (5.5%) cases; Semi successful group included patients, which became disobstructed after ESWL, but the some of the stone fragments were dislocated into lower calyx and were not eliminated. Unfinished treatment (Patient disappeared after the initial sessions) were in 262 (15.9%) cases. 81 cases were not successful. 31 patients from this group underwent urethrorenoscopy, 49 patients--open surgery and 7--PNL. In conclusion, ESWL is the "golden" standard treatment of Urinary stone disease in cases of carefully performed examination and management. Careful study of every single case, gives as the possibility to avoid expensive and invasive procedures and reduce the risk of complications.
