In the distal part of the left ureter, a 5-6 mm calculus is present. The ureter and collecting system proximal to the calculus is somewhat ectatic compared to the right side, but there is no marked widening of the ureter, nor is there any hydronephrosis. However, there is stranding of the perirenal fat and findings consistent with small perirenal fluid collections. This raised the suspicion of a rupture of the renal pelvis (urinoma). The patient was therefore called back from the ward for a repeated exam to evaluate if there was any leakage of excreted contrast.
