AIM: To investigate the characteristics of urolithiasis associated with Crohn's disease (CD) in a sample of Tunisian population. METHODS: We retrospectively studied 184 patients with CD to reveal any urolithiasis during evolution. Evidence for the presence of renal calculi was obtained from plain films, ultrasonography or intravenous urography and computed tomography. RESULTS: Renal calculi were found in only three patients with CD. All patients were woman. Mean time from diagnosis of CD to diagnosis of calculi was 22 months (range 6 to 48 months). Clinical features were not specific. Calculi were bilateral in two cases. CONCLUSIONS: The rate of concurrent urolithiasis was very low in the present series of Tunisian patients. Although rare, efficient treatment and prevention of calculi formation are mandatory in CD patients'.
