Chronic kidney disease RIGHT KIDNEY: Echogenic parenchyma. Questionable 5.7 x 5.4 x 5.9 cm complex mass lesion arising from the lower pole of the right kidney. No stone. Minimal hydronephrosis. Right kidney 9.9 cm in length.LEFT KIDNEY: Echogenic parenchyma. Benign appearing cyst. No stone or hydronephrosis. Left kidney 9.3 cm in length.OTHER: Bladder nondistended.
Echogenic renal parenchyma consistent with medical renal disease/parenchymal dysfunction without significant obstruction or stone.Questionable right lower pole complex mass lesion versus partial duplication. The degree of echogenicity of the right kidney makes it difficult to differentiate between a mass lesion or partial duplication; noncontrast CT may be helpful for further characterization.
