The left kidney has not crossed the mid-line and lies on the right side, inferomedial to the right kidney and fused to the lower pole, inferring crossed fused renal ectopia.

The right renal collecting system notes a 14 mm stone with mean attenuation values of 751HU.

A 28mm calyceal diverticulum is observed in the fused part of the kidneys that contain several hyperdense stones less than 11mm and with mean attenuation values of 7311HU. In addition, a 10mm stone with mean attenuation values of 967HU is evident in the proximal part of the left ureter, which causes mild hydronephrosis.

Grade I spondylolisthesis of L5 on S1 is present.
