Abstract:
PURPOSE: Since ESWL had been developed, many experiences of the treatments to urinary stones with various type of lithotriptors were reported. We evaluated the efficacy of EDAP-LT01 piezoelectric lithotriptor according to the size, location of the stone, number of the treatment session, adjuvant therapy and cause of failure. MATERIALS AND METHODS: We retrospectively analyzed the data of 660 cases who had been treated with ESWL. Among the patients, the renal stones were 122, the ureteral stones were 452, and combined with renal and ureteral stones were 43 cases. The mean size of stones was 13mm (range: 4-38mm). ESWL was performed to all the patients with urinary stones except complete staghorn calculi. No anesthesia was performed except in one child (5 years old). RESULTS: Overall success rate was 94.7%, and there were close correlations between the success rate and the size. The mean number of sessions was 2.4. There was no significant complication, but 35 cases were failed by ESWL monotherapy, and auxiliary procedures were done in 21 cases. Efficiency quotient was 0.59. CONCLUSIONS: The ESWL with EDAP-LT01 seems to be effective and safe to treat the urinary stones of various location and size, even compared to the lithotriptors of other type. We also propose that ESWL monotherapy with this machine is efficient for the treatment of the partial staghorn calculi and stones larger than 30mm.
