Abstract:
PURPOSE: We analyzed the therapeutic results of 703 cases of urinary calculi treated using an EDAP-Sonolith Praktis, an electroconductive lithotriptor (ECL). MATERIALS AND METHODS: Between January 2000 and June 2004, 703 patients meeting the study inclusion criteria were treated with an EDAP-Sonolith Praktis. The site and size of the stones, session, auxiliary procedure, success rate, causes of failure, complication, efficiency quotient (EQ) and retreatment were analyzed. RESULTS: The records of 703 patients, in whom urinary calculi were treated by extracorporeal shock wave lithotripsy, using an EDAP-Sonolith Praktis, were retrospectively reviewed. The success rates were 99.3, 92.5, 66.7 and 12.5% for stone sizes < or=9, 10-19, 20-29 and > or=30mm, respectively, with an overall success rate of 95.3%. The EQ, mean number of session and retreatment rate were 0.71, 1.7 and 30.6%, respectively. As auxiliary procedures, double-J stenting, ureteroscopic stone removal and open surgery were performed in 6, 15 and 1, respectively. The complications were gross hematuria, flank pain, steinstrasse, nausea and fever, which were successfully controlled by conservative treatment. CONCLUSIONS: EDAP-Sonolith Praktis, an ECL, is an efficient and safe outpatient procedure for initial urinary calculi treatment.
