Abstract

Aim: The present study aimed to determine if there is a difference in efficacy and safety in the use of electrohydraulic versus electromagnetic lithotripters when used for the treatment of a single kidney stone of 10-20 mm. Material and methods: We performed a retrospective study on a group of 106 patients with a single kidney stone which was treated by lithotripsy with devices that had different sources of shock wave generation. Results: The overall success of the treatment using electrohydraulic lithotripsy was 85.2% for kidney stones of 10-14 mm and 66.7% for kidney stones of 15-20 mm while for electromagnetic lithotripsy, the success rate for stones of 10-14 mm was 97% and 88.7% for kidney stones of 15-20 mm. Regarding postprocedural complications, we found 7 cases of steinstrasse, all in patients with kidney stones of 10-15 mm, of which 2 in the group of patients treated with electromagnetic lithotripsy and 5 in the case of those treated by electrohydraulic lithotripsy. We also found two post-procedural cases of perirenal hematomas, one in each group. None of the patients required additional therapeutical measures. Conclusions: There were no significant differences in the efficiency rate and safety profile for the treatment of kidney stones of 10-20 mm. However, the electromagnetic lithotripter has definite advantages in terms of the quality of the tracking and focusing system of the calculus compared to the bifocal system of the electrohydraulic lithotripter.
