Renal hypertension is a disease which envolves high blood pressure caused by narrowing of the arteries supplying the kidneys. It is a form of secondary hypertension - a form of hypertension whose cause is identifiable.
When the arteries that carry blood to your kidneys become narrow or partially blocked, less blood flows to the kidneys. The kidneys mistakenly respond as if your blood pressure is low and give off hormones that tell the body to hold on to more salt and water. This causes your blood pressure to rise.
Renal hypertension can be diagnosed using digital image processing of radiographs. Treatment may involve angioplasty, which is the mechanically widening of a blood vessel, and stenting of the renal arteries. Renal hypertension may be related to other diseases of the epithelium.
