A ten-year experience with diagnosis and therapy of metabolic abnormalities and crystallization risks in patients with recurrent urolithiasis is presented. Since 1985, more than 900 persons with recurrent urolithiasis have been examined at the Metabolic Centre of the Hospital in Sternberk. The patients were examined routinely at ambulance or during hospitalization; the examination consisted of repeated urine and blood collections after the diet with various content of calcium and salt. All initial data (case history, physical finding, biochemistry, radiodiagnostics) were processed by a semi-expert computing program SOFT which was also used for monitoring of the therapy. Then the patients were divided into individual risk groups (Pak). Of all probands, the group of 130 patients (satisfying the strict criteria of the study) was selected and the data obtained was processed statistically. The group of 130 patients with recurrent urolithiasis (all of them were drug-treated) was compared to the group of 50 individuals with urolithiasis treated by diet and regimen measures. The patients given drugs showed a significantly increased crystallization inhibitors concentration in urine and reduced crystallization promotors, or relative saturation of some lithiatic substances. The paper analyzes the effect of the mostly administered drugs on crystallization risks and some less known "metabolic" indications of application of some drugs are recommended. It is concluded that the dietary, drinking and regime measures are basic for a good therapy of patients with urolithiasis, but patients with recurrent urolithiasis should be applied a selective metaphylaxis of drugs after routine metabolic examination. This finding is supported by a low number of recurrent urolithiasis.
