Determination of the composition of kidney stones and prediction of the efficacy of extracorporeal shock-wave lithotripsy by X-rays / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the clinical value of determination of composition of kidney stones by shap and density and of prediction of the efficacy of extracorporeal shock-wave lithotripsy (ESWL) by X-rays. Methods The data of 358 patients were analyzed,with 204 male and 154 female and with 276 cases of solitary stones and 82 cases of multiple stones.Determine the composition of kidney stones by shap and density,predict the efficacy of ESWL by X-rays,and choose the appropriate method of treatment.Analyze stone chemical property by Infrared stone composition automatic analyzer to checkout the prediction results before surgeries. Results 339 cases were successful to remove stones after treatment.The prediction results of 308 cases (86.0％) were consistent in stone chemical property,and the preperative prediction results of 339 cases (94.7％) were consistent in ESWL efficacy. Conclusions Determination of composition of kidney stones and prediction of the efficacy of ESWL by X-rays were feasible.
