Ultrasonography of 68 yr male parkinson patient: echogenic renal cortices-could be parenchymal disorder & lots of residual urine (59 cc).is it risky?

Ultrasound: Echogenic kidneys on ultrasound may represent medical renal disease. This should be correlated with the patient's renal function and BUN and creatinine. A valatta with a large amount of urine may be normal. A pre-and post void bladder sonogram should be performed. This may be related to a enlarged prostate or a neurogenic bladder. Discuss with nephrologist/urologist.
