Abstract

PURPOSE: To compare the results of extracorporeal shock wave lithotripters according to three shock wave energy sources; piezoelectric (EDAP LT 01+), electromagnetic (Storz Modulith SLX) and electroconductive (EDAP- TMS Sonolith VISION), for the treatment of urinary stones. METERIALS AND METHODS: Between February 1990 and March 2006, 1,504 patients (1,691 renal units) were treated with LT-01+(group A), 2,265 patients (2,500 renal units) with a Modulith SLX (group B) and 927 patients (946 renal units) with a Sonolith VISION (group C). The success rates, number of sessions and complications were examined. Statistical analyses were also conducted according to the size and location of the stones.
RESULTS
There were no significant differences in the success rates between the three groups (group A, 97.8%; group B, 98.1%; group C, 97.1%). According to the stone size, the success rate for stones more than 1cm(2) was lower in group C than in groups A and B. According to the location, group C had a lower success rate than groups A and B for renal stones, while there were no differences between the three groups in the treatment of other stone locations. The number of treatment sessions for group A was greater than those for groups B and C (group A, 3.83; group B, 1.85; group C, 1.93). Many more sessions were required for group A in comparison with groups B and C in case of renal stones, ureteropelvic junction and upper ureteral stones. The number of sessions for group B was the least for lower ureteral stones. Complications, including steinstrasse, fever, perirenal hematoma and hematuria, were detected in groups A, B and group C at 10, 15.3 and 7.1%, respectively.
CONCLUSIONS
There were no differences in the success rates between the three extracorporeal shock wave lithotripters using a shock wave generator. The mean number of treatment sessions was most with the piezoelectric type; whereas, complications were most prevalent with the electromagnetic type.
