The aim of the study is an increasing frequency of predicting the results of remote shock wave lithotripsy in patients with nephrolithiasis. Matherials and methods. The study involved 127 patients with diagnosed urolithiasis with the presence of a single renal calculus from 10 to 17 mm in size. All patients underwent a complex of laboratory analyses, multispiral computed tomography. The concrement elimination was carried out by extracorporeal shock-wave lithotripsy. Results. In this study, there were no sufficient relationships between the maximum size and average density of stone and the number of extracorporeal lithotripsy sessions in patients with nephrolithiasis. On the contrary, the parameter of the "homogeneity" of the stone, reflecting its structure, showed a strong reliable relationship with the effectiveness of extracorporeal shock-wave lithotripsy, as well as high sensitivity and specificity. Using this indicator, it was possible to increase the percentage of successful procedures from 56,9% to 75,8%. Conclusion. The maximum size and average density of stone have insufficient diagnostic value in predicting the results of shock-wave lithotripsy in patients with single kidney stones 10-17 mm in size. In this case, an indicator of the "homogeneity" can be used to select the optimal method of treatment.
