Ureteral calculosis: ESWL in situ and after preliminary manoeuvres

Abstract

Extracorporeal shock wave lithotripsy is nowadays first choice treatment of ureteral stones. Shock wave generator technology has greatly advanced since the first electrohydraulic lithotriptor was introduced. Third generation lithotriptors combine all these advantages and integrate them into a multi-functional X-ray system. From January 1996 to June 1996, 63 patients (43 male and 20 female) suffering from ureteral calculosis were treated. Stone localisation was in 35 cases (55%) the lumbar ureter, in 3 (5%) the iliac ureter and in 25 (40%) the pelvic ureter. A Storz Modulith SLX lithotriptor with an electromagnetic cylindrical source was used. Easy positioning of the patient and dry coupling make treatment procedures simple. Furthermore, general anesthesia is not required and analgesic sedation (Fentanest and Diazepam) is often unnecessary, especially in ureteral stones.
