Fig. 5C. —74-year-old man with microhematuria. Patient is on warfarin sodium for atrial fibrillation. Maximum-intensity-projection images from CT scans before (C) and after (D) contrast administration show to better advantage upper pole caliceal diverticulum, containing calculus (arrow, D). Two smaller calculi are also seen in interpolar region. Most commonly, caliceal diverticula are asymptomatic, but because of urinary stasis, complications can include both infection and formation of stones, which may become entrapped in diverticula.
