Urachal remnant disease is a relatively rare urological condition that presents a variety of clinical problems in adult patients. Contrast-enhanced multi-detector row computed tomography (MDCT) urography is a new diagnostic imaging technique providing comprehensive evaluation of the upper and lower urinary tract. MDCT urography performed with a combination of unenhanced, nephrographic phase, and excretory- phase imaging can demonstrate a wide spectrum of disease in these patients with a single study. We report a case of vesicourachal diverticulum containing calculus, which was diagnosed by MDCT urography.
