ABSTRACT
A total of 9 patients [2 children and 7 adults] underwent ESWL using the Dornier MPL 9000 lithotriptor in prone and supine positions. Three patients had horseshoe kidneys, 2 patients had ectopic lower lumber kidneys, and 4 patients had ectopic pelvic kidneys. Stones inside horseshoe kidneys were localized by X-ray and treated in supine position and stones inside ectopic kidneys were sonographically localized and treated in prone position. Complete disintegration was achieved in all patients, 7 after one ESWl treatment and 2 after 2 ESWL treatment sessions. Seven patients were stone free after 3 months and the other 2 patients needed another 2 months to be stone free. The study recommended ESWL for treatment of stones in anomalous kidney, and the prone position for stones near the bony pelvis is recommended
