EFFECTIVENESS OF EXTRACORPOREAL SHOCK WAVE LITHOTRIPSY IN PATIENTS WITH RENAL CALYX CALCULI

Abstract

THE AIM of the investigation was to assess the effectiveness and safety of a new minimally invasive method of treatment of patients with calculi – extracorporeal shock wave lithotripsy. PATIENTS METHODS. Extracorporeal shock wave lithotripsy was used in 233 patients with renal calyx calculi. In 115 (49.3%) patients the calculi were found in the upper calyx of the kidney,in 80 (34.3%) – in the middle calyx, in 32 (13.7%) – in the lower calyx, in 6 (2.6%) patients there were calculi in the upper and middle calices. RESULTS. Complete destruction of the calculus of the renal calices after extracorporeal shock wave lithotripsy was diagnosed in 208 (89.3%) of the patients, partial – in 18 (7.7%) patients, the calculus was not destructed in 7 (3.0%) patients. Outcome of all fragments of the completely destructed calculus during 3 months after lithotripsy was noted in all patients with localization of the calculus in the upper calyx, in 87.3% of the patients with localization of the calculus in the middle calyx, and in 50% of patients with localization in the lower calyx. CONCLUSION. For the successful treatment of patients with nephrolithiasis with calculi localized in renal calices of great significance is the correct decision on the indications and contraindications for extracoreporeal lithotripsy.
