Abstract
Formation of urinary tract concrements is a common disease and steps should be taken in order to elucidate the underlying mechanisms and to give the patients appropriate advice and medical treatment. This present article summarizes the principles for recurrence preventive measures in patients with uric acid, infection, cystine and calcium stone disease. Categories of stone formers are identified with the aim of providing a basis for an individualised treatment with a reasonable patient's compliance. The recommendations are in line with those given by the EAU guideline group for urolithiasis.
