Understanding Renal Hypertension: A Detailed Overview

Alvin Hopkinson Health Guide
  • Hypertension is a common issue among many individuals. Basically, it is high blood pressure and can be controlled with medication and lifestyle modifications. Another form of hypertension is renal hypertension, this is considered to be a type of secondary hypertension. Renal hypertension affects less than one percent of individuals that have been diagnosed with primary hypertension.


    There are actually two different types of renal hypertension. The first is atherosclerotic renovascular and the second is renovascular hypertension. The majority of cases of hypertension seem to be related to the lifestyle the individual lives, their genetic make up, environment and choices they make by putting toxins in their system, such as smoking, high salt intake, obesity and stress to name a few.

    Atherosclerotic renovascular hypertension is when the renal artery has plaque deposited on it. This causes the artery to become smaller which causes the blood flow to have difficulties flowing with ease. This condition is more popular among men that are 45 years old and over. Actually, 2/3 of the diagnosed cases of renovascular hypertension have been done in men that are over 45 years old. Typically, the majority of individuals with renovascular hypertension find out the issue has targeted both of the arteries to the kidneys.


    Symptoms and Causes


    When the renal artery is restricted by deposit's the flow of blood to the kidneys is also restricted. This causes the kidneys to produce a protein called renin which is released into the blood stream. The renin then goes through its own process and turns into enzymes that cause the sodium to be retained. There is then a constriction of the arterioles.


    Generally, a doctor will consider and begin testing for renovascular hypertension when and if a patient that is over the age of 55 or younger than 30 begins to show increased issues with their existing diagnosed hypertension. However, in some cases the symptoms ago unnoticed, are not there or come on suddenly.




    Approximately 50% of the individuals that are diagnosed with renovascular hypertension seem to have a very distinct sound that is recognizable when a doctor listens to the upper abdominal area with a stethoscope. Generally, there are other tests that should be performed to determine the severity of the hypertension in the individual. Some of the testing can be risky and costly for the patient.


    There are imaging tests that can be performed in order to properly diagnose renovascular hypertension. One test is the intravenous urography. This test involves a dye being injected into the individuals kidneys and then pictures are taken. The images will be compared to notice an abnormality in the function of the kidneys.


    Another test is the renal arteriography, this one a substance is directly inserted into the renal artery. This shows a contrast that in x rays can be determined to measure the function of the kidneys.


    Treatment for renal hypertension can vary depending on the severity of the hypertension. However, generally anti-hypertensive medication does not work. Many doctors decide the best course of treatment for renal hypertension is inserting a catheter in the renal artery. This is called percutaneous transluminal angioplasty or PTA. The goal is to eliminate the blockage. This procedure has a 90% success rate. However, the rate decreases slightly over about one year to a success rate of about 60%.
