We present a case of renal stone associated with bilateral pelvic diverticula. The initial diagnosis by ultrasonography and plain abdomen radiography (KUB) was urolithiasis with a 15-mm calculus in the right renal pelvis. ⋯ So, further evaluations were performed by using repeated ultrasonography, intravenous urography, and computerized tomography, which revealed the presence of diverticula in both right and left renal pelvises with stone fragments within the right sided diverticulum. We concluded that intravenous urography and contrast-enhanced computerized tomography are essential for confirmation of diagnosis when ultrasonographic findings suggest the presence of renal cystic lesions, or when stone fragments are not yielded after extracorporeal shock wave lithotripsy.
