The clinical picture of renal hypertension.
Renal hypertension can usually be recognized only by examining all the features of the hypertensive illness. On the other hand, the investigation of a case of hypertension whose genesis was previously unclear can lead to the diagnosis of a hitherto unrecognized renal disease. The blood pressure values found in patients with renal hypertension are of widely differing degrees of severity. Slight rises in blood pressure (e.g. 140/90 mm Hg), can be a sign of renal disease in adolescent patients. 10-15% of the cases of chronic renal hypertension develop into malignant hypertension. High diastolic values above 120 mm Hg without renal symptomatology and without reduced renal function speak against a primary renal cause of the rise in blood pressure. The finding of hypertension developing during the course of renal disease is, with respect to the hypertensive cardiovascular complications, just as important as in the case of essential hypertension. Complications which can occur during renal hypertension include cardiac insufficiency, hypertensive encephalopathy, retinopathy, hypertensive crises and acceleration of the renal disease.
