CT
Hyperdense stone is seen at the middle part of the right ureter, with moderate proximal hydroureter and hydronephrosis. It measures about 17 mm and has a density of about 435 HFU. A large amount of fluid collection is seen mainly at perirenal space tracking to the pelvis region.
Delayed images reveal contrast extravasation with evidence of a connection between this fluid and the middle calyx indicating a urine leakage picture consistent with urinoma.
