| Abstract |
Purpose
The electroconductive lithotriptor (ECL) is a new concept for shockwave generation in which a conductive solution channels the discharge between the anode and cathode. To evaluated the effectiveness and safety of extracorporeal shock wave lithotripsy (ESWL), with a Sonolith lithotriptor, in patients with urinary stones.
Materials and
methods
Out of 183 patients treated, complete follow up data were available on 177 patients, between August 2001 and January 2004. The study group comprised of 105 men and 72 women (1.46:1), mean ages of 47.70 and 52.83, respectively. The number of sessions and success rates according to the stone sizes and location of stones were analysed. Auxiliary measures, other treatment modalities and complications were also reviewed.
Results
The overall success rate of ESWL was 96.05% (170 of 177 patients). For the stones of calyx and renal pelvis, regardless of stone size, the ESWL was 100% successful. For upper ureter stones, the success rates ranged from 90%, for stones ll-15mm in size, to 100%, for stones less than 5mm and more than 15 mm in size. For lower ureter stones, the success rates ranged from 50%, for stones 11-15mm in size, to 100%, for stones less than 5mm and more than 15mm in size. The success rates of midureter, staghorn and multiple lesion were 100%, 66.67% and 66.67%, respectively. The number of sessions correlated the stone size. Post-ESWL complications were observed in 4 cases (2.26%).
Conclusions
The success rate of ESWL was 96.05%. In our experience, ESWL has proved to be an effective and safe method to treat the urinary stones. |
