Diagnosing Renal Artery Stenosis

Detect and Manage Your Kidney Disease

NYU Langone doctors are experts at diagnosing renal artery stenosis. The condition results from a narrowing of one or both renal arteries, the blood vessels that lead to the kidneys. As blood flow decreases, the kidneys cant function properly. It can also cause the kidneys to produce a chemical called renin, which raises blood pressure.;

The kidneys are a pair of bean-shaped organs located on both sides of the lower back. Their job is to filter and remove waste from the blood, help control blood pressure, and regulate electrolytes, which are minerals that conduct electrical impulses in the body.;

Typically, renal artery stenosis develops as a result of atherosclerosis, which occurs when plaque, a waxy substance composed of cholesterol, fat, and calcium, builds up in the arteries. Risk factors include a high-fat diet, a sedentary lifestyle, smoking, and a family history of the condition.;

Less commonly, renal artery stenosis can be caused by fibromuscular dysplasia, a condition in which many arteries in the body are prone to narrowing.

When plaque builds up in the renal arteries and blood flow decreases, the kidneys release renin, a substance that raises blood pressure. This is often the first sign of renal artery stenosis. Some people also experience fluid retention, shortness of breath, headaches, and ankle swelling. If both renal arteries are blocked, kidney failure can occur.;

How Do The Kidneys Work

The body takes nutrients from food and converts them to energy. Afterthe body has taken the food that it needs, waste products are leftbehind in the bowel and in the blood.

The kidneys and urinary system keep chemicals, such as potassium andsodium, and water in balance, and remove a type of waste, called urea,from the blood. Urea is produced when foods containing protein, such asmeat, poultry, and certain vegetables, are broken down in the body.Urea is carried in the bloodstream to the kidneys.

Two kidneys, a pair of purplish-brown organs, are located below theribs toward the middle of the back. Their function is to:

  • Remove liquid waste from the blood in the form of urine

  • Keep a stable balance of salts and other substances in the blood

  • Produce erythropoietin, a hormone that aids the formation of red blood cells

  • Regulate blood pressure

The kidneys remove urea from the blood through tiny filtering unitscalled nephrons. Each nephron consists of a ball formed of small bloodcapillaries, called a glomerulus, and a small tube called a renaltubule.

Urea, together with water and other waste substances, forms the urineas it passes through the nephrons and down the renal tubules of thekidney.

What Is Kidney Failure

The kidneys;are designed to maintain proper fluid balance in the body, remove waste and eliminate toxins from the blood. The kidneys make urine, which carries away those products of elimination and excess fluid. They also make hormones, which stimulate the making of red blood cells in the bone marrow and strengthen the bones. The term kidney failure describes a situation in which the kidneys have lost the ability to effectively carry out these functions. A build-up of waste levels can cause a chemical imbalance in the blood, which can be fatal if left untreated. Patients with renal failure may develop a low blood count or weak bones over time. Chronic renal failure can be caused by a variety of diseases and means failure of kidney function over time.

Other conditions can result in acute;kidney failure, such as a drop in blood flow to the kidneys, blockage of urine flow, or damage from infections, certain medications or contrast materials;used in imaging. Acute kidney failure can occur quickly and may leave the kidneys with permanent damage. In many cases, it occurs in patients who are already critically ill and require intensive care.

Its Your Decision Whether You Get A Preventive Screening

Theres nothing wrong with signing up for these screenings, so long as you understand they may not reveal any useful information. In some cases, the findings may lead to more testing.

If you are very concerned about your cardiovascular risk, these tests are reasonable, if you dont mind paying $135 to $150 out of pocket, says Dr. Laffin. But what will you do with the results? Screenings are only a small part of determining risk.

If you are very worried about your risk, tell your doctor. Together, you can determine your actual risk and make a plan of action to lower it, he says.

There are home tests that allow you to collect blood or urine samples and drop them off at a lab or mail them in. Results are interpreted by a doctor and sent to you. These may be a good option for people who are unable to visit a doctors office or don’t have insurance to cover the tests. However, if youre able to make an appointment to see a doctor, consider that option first.

Kidney Failure From Sepsis

Kidney failure is very common in sepsis, but it can be reversed most of the time with the proper treatment of sepsis. If you would like to understand what sepsis is, please read this article: Low blood pressure and a fever, think sepsis. In summary, sepsis is a potentially life-threatening complication from an infection where the body can get overwhelmed and crash down.

Patients with severe sepsis and kidney failure may need intensive care in the ICU. The treatment is focused on treating the infection and supporting the body to maintain good blood circulation. If a good blood circulation with normal blood pressure is restored, the kidneys start to recover, and the kidney failure can be ultimately reversed back to normal.

Sonographic Evaluation Of The Kidneys And Urinary Tract

Because of their location, architecture, and limited spectrum of pathology, the kidneys are ideally suited for evaluation by ultrasound. In addition, it is safe, readily available, easily performed at the bedside or in the office, and free of radiation. For these reasons, sonography is the preferred imaging modality and often the only one required. Evaluation includes assessment of the size and shape, the echogenicity, the urinary space , the presence of masses, and the vasculature. Very few findings are specific, and interpretation, therefore, requires clinical correlation, another reason for the participation of nephrologists in this procedure.

Kidney Failure From Severe Dehydration

Severe dehydration is one of the most common causes of reversible kidney failure. Dehydration can be a serious life-threatening disorder. Read Hospitalized for Dehydration if you would like to understand what to expect when hospitalized for dehydration. Kidney failure is one of the most common complications of dehydration.

During the early stages of every dehydration, your kidneys essentially shut themselves down to preserve water. Once the dehydration is corrected, the kidneys start to open up and quickly get your urine production back to normal. The blood tests I mentioned earlier help decide whether the kidney failure is still in the early rapidly reversible state. If the ratio of BUN to Cr is equal to or more than 20, your kidney failure from dehydration is likely in the early rapidly reversible stage.

When the treatment of dehydration is delayed for several days, your kidneys go into the second stage of kidney failure. Small tubes inside the kidneys start to die off and you have structural damage inside the kidneys. This type of kidney failure is medically called Acute Tubular Necrosis or ATN. Necrosis simply means dying off. ATN is still reversible in most cases, but it takes longer to recover from. The tubes that die off will have to regenerate so that the kidney failure can ultimately be reversed. It may take a few weeks to reverse the kidney failure when ATN is present.

Can Ultrasound Detect Chronic Kidney Disease

Model Selection: Prediction Of Continuous Egfrs Through Cnns

We predicted eGFRs based on patients kidney ultrasound images by using deep CNNs. Our neural network architecture, as illustrated in Fig. , was referenced from the ResNet-101 model. In brief, the ResNet-101 model comprises a bunch of residual blocks, with each block being a combination of convolution and identity-mapping layers, resulting in a total of 101 layers . To predict the patients eGFRs, we replaced the last 1000-class classifier in the ResNet-101 model by using a regressor of consecutive fully connected layers, comprising 512 , 512 , 256 , and 1 , as illustrated in Fig. . We employed a dropout layer to reduce overfitting between every two consecutive fully connected layers, where the dropout probability was determined using the grid search method. The activation function of all layers except the output layer used rectified linear units; the output layer adopted a linear activation function because this prediction task was a regression-type problem with the output values ranging from 0 to >100. For this regression-type prediction problem, we optimized the mean squared error defined as follows:

where \ and Yt are the predicted and actual eGFRs of sample i, respectively.

Kidney ultrasounds are performed in both inpatient and outpatient settings. The following steps apply:

  • Youll prepare for the procedure by removing your street clothes and any jewelry that youre wearing. A hospital gown will be provided for you to change into.
  • You will be positioned on your stomach in the examination area.
  • A gel will be applied on the skin where the transducer goes. This substance serves to heighten contact between the transducer and your skin, improving sound wave transmission into the body. ;
  • The transducer emits sound waves into the body. These waves will reflect off the kidney and other internal structures and, on being captured by a computer, will provide the data it needs to create an image of your organs.
  • The images created by the ultrasound will go into digital storage, for future reference.
  • Multiple images of your bladder, both before and after urination, will be taken. This will assist your physician in interpreting the ultrasound data, because of the close working relationship between the kidneys and bladder.
