Nephrology is the medical specialty that deals with the study of the kidneys and their pathologies including, of course, the prevention, diagnosis and treatment of these kidney diseases.
Pathologies that may be related to the kidneys are very broad and include those related to the urinary tract, hydroelectrolyte alterations, acid-base balance … and also arterial hypertension and vascular risk factors.
Among all these related pathologies, arterial hypertension and cardiovascular risks are the most frequent, so that much of the time of the specialists in the nephrology department is dedicated to treating these cases. This is the reason why in most hospitals the hypertension unit is part of the nephrology services.
Many of the pathologies related to the kidneys are treated by medication, but in some cases surgical treatment is required, that is, renovascular surgery.
What is renovascular surgery?
Renovascular surgery is used in those cases that are not possible to control only by medication. An example of this is renal artery stenosis when it is too severe.
Renal artery stenosis consists of the narrowing and blockage of the arteries that carry the blood to the kidneys. This narrowing and blockage is caused, in most cases, by arterial hypertension, which causes calcified plaques to deposit and accumulate in the arteries. Other pathologies, such as fibromuscular dysplasia, can also cause the development of renal artery stenosis.
Due to the narrowing of the renal artery, less blood circulates to the kidneys and they start functioning as if the blood pressure is low, releasing hormones that cause the body to retain more salt and water, which ultimately results in the blood pressure increases.
When the stenosis of the renal artery cannot be controlled only with medication, it is necessary to resort to surgery. The recommended procedure is a renal angioplasty, which involves inserting a small balloon with a catheter into the blood vessel, placing it in the obstructed artery and inflating it to move the obstructing plaque, getting the blood to flow normally again. Depending on the case, this process can be repeated once or several times at different points, and a small tube is used to ensure that the blood flow in the artery remains open.
This procedure is minimally invasive surgery and can last several hours. It is usually performed under local anesthesia, and hospitalization lasts 24 to 48 hours.
With this surgery, a better circulation of blood in the renal artery is achieved, although the result depends on the location where the block was, the size of the arteries and the level of obstruction. Periodic reviews are recommended after surgery.
