urea and Renal Artery Obstruction

urea has been researched along with Renal Artery Obstruction in 55 studies

pseudourea: clinical use; structure
isourea : A carboximidic acid that is the imidic acid tautomer of urea, H2NC(=NH)OH, and its hydrocarbyl derivatives.

Renal Artery Obstruction: Narrowing or occlusion of the RENAL ARTERY or arteries. It is due usually to ATHEROSCLEROSIS; FIBROMUSCULAR DYSPLASIA; THROMBOSIS; EMBOLISM, or external pressure. The reduced renal perfusion can lead to renovascular hypertension (HYPERTENSION, RENOVASCULAR).
