Patient Data

Age: 55 years
Gender: Female


CT IVP demonstrates numerous small calcifications located in the renal calculi which are non-obstructing and measure up to 3mm on the right and 4mm on the left. Urographic phase imaging demonstrates dilated renal tubules in which these non-obstructing calculi are located.
