[|Human|] My husband has had an ultrasound that shows bilateral renal parenchymal thinning. Please advise course of treatment, degree of concern we should have and follow up i.e. should he be referred to a specialist. His history include hypertension fairly newly diagnosed. Thank you.
[|AI|]  Hi, Thanks for writing in. The kidney consists of renal parenchymal and renal pelvis. Renal parenchymal can be divided into renal medulla and renal cortex. Bilateral renal parenchymal disease means that the renal impairments are in the medulla and cortical areas affecting both the two kidneys. Thinning of renal parenchymal is a condition in which the cortex is thinned out and this can can be due to many reasons. The possibilities are glomerular diseases and chronic interstitial nephritis. Persistent high blood pressure or bilateral kidney stones can also cause this. Evaluation of kidney functions in detail is required, and he must take guidance from a nephrologist.
