Renal hypertension is generally a more serious condition, but renal hypertension often has a better prognosis if detected and treated early. Renal hypertension includes acute and chronic glomerulonephritis, pyelonephritis, and other causes, and renal hypertension can cause a dramatic increase in blood pressure. If acute and chronic glomerulonephritis and pyelonephritis are treated in time and the patient’s kidney disease is restored, hypertension as a secondary symptom can be cured or relieved. In addition, patients with renal insufficiency have elevated blood pressure, which is often a more serious condition. For patients with severe renal insufficiency, such as uremia, it is often necessary to give peritoneal dialysis, hemodialysis and other methods to correct the state of hypertension. In patients with renal hypertension, when there is significant shrinkage of the kidneys as well as reduced renal function, the hypertension tends to be stubborn and has a poor prognosis.
