72-year-old male with worsening renal function. Evaluate for obstruction. RIGHT KIDNEY: Right kidney measures 10.5 cm in length and is highly echogenic consistent with parenchymal disease. This has progressed when compared to the prior exam. There are several simple cysts present the largest measuring 3.1 cm in greatest diameter. In the lower pole, there is a complex appearing and slightly hypoechoic area within the cortex measuring 1.1 cm in greatest diameter. Review of the prior study there was a simple cyst in this location and therefore this likely represents a complex cyst.LEFT KIDNEY: The left kidney measures 10.5 cm in length and is highly echogenic consistent with parenchymal disease. This has progressed when compared to the prior study. There are multiple exophytic and small cortical cysts present. Largest cyst measures 2.6 cm in diameter. There is mild fullness of the collecting system which likely is due to associated parenchymal volume loss rather than obstruction.OTHER: Patient voided prior to the procedure and therefore the bladder is almost empty and appears very thick-walled.
Progressive increase in echogenicity the kidneys.Bilateral renal cysts with likely complex cyst on the right.Fullness of left renal collecting system with associated parenchymal loss. No gross evidence for hydronephrosis.
