Nephrolithiasis is a highly prevalent pathology with a 10% lifetime risk in the Western population. Although it is often minimized and qualified as "idiopathic" significant comorbidities are frequently observed, e.g. the metabolic syndrome, type 2 diabetes mellitus, hypertension and bone fragility. Therefore nephrolithiasis can be regarded as a systemic disorder. A specialized diagnostic and therapeutic approach should be offered to such patients with active kidney stone disease in order to prevent stone recurrence and favor early diagnosis of said comorbidities.
