IMPRESSION : BILATERAL DIFFUSE RENAL PARENCHYMAL DISEASEMILD PELVOCALIECTASIS IN THE RIGHT KIDNEYRENAL CYST IN THE LEFT KIDNEYNEGATIVE ULTRASOUND OF THE URINARY BLADDER [/INST] Hi, The good news is that your kidney sizes are preserved but just near the lower limit of normal. The increased echogenicity explains that your kidneys are experiencing some form of insult either acute or chronic. A single cortical cyst is of no significance unless there is underlying infection or malignancy. At this stage you must do all of your necessary work up to investigate and treat the cause of your kidney insult. Regards </s>
