Background: In a previous study, we showed our experience in a group of 54 patients with a high risk of urolithiasis recurrence, who were subjected to a complete metabolic evaluation. Aim: To report the evolution of these patients after 5 years of follow-up. Patients and Methods: All patients underwent a general management of urolithiasis plus specific treatments for underlying metabolic disorders. Each patient had an annual medical assessment including a clinical examination, urinalysis and imaging studies (non-enhanced computed tomography scan, ultrasonography and plain abdominal Rx rays). In every case, the underlying metabolic disorder, treatment adherence, stones on imaging studies and symptomatology were evaluated. Adherence of general and specific measures were evaluated subjectively. Failure of secondary prevention was defined as the recurrence of clinical or imaging urolithiasis (increase of the number of lithiasis) despite a correct treatment of the metabolic disorders. Results: Twenty nine patients completed the follow-up. Mean age was 45 years old. Nineteen patients (65%) had only one metabolic disorder, three patients (10%) two disorders, one patient (3%) four disorders, and six patients (21%) a normal metabolic study. The median of follow-up was 54 months (45-60). During that period, twenty-three patients (79%) kept the treatment as it was indicated. In this subgroup, 21 had no clinical or imaging recurrence of urolithiasis during follow-up (91%). Total adherence to treatment and follow-up was 42% (23/54) of the initial group of patients. Conclusions: A complete metabolic study allows to identify patients with a high risk of urolithiasis recurrence, enabling a specific treatment of the metabolic disorder. Our experience shows that 75% (21/29) of patients remain free of recurrence at five years of follow-up
