What Are Different Types Of Kidney Infection

Kidney infection, or pyelonephritis, may be classified as uncomplicated, complicated, or chronic kidney infection .

A complicated kidney infection refers to a kidney infection in which there is an accompanying condition that increases the risk of severe infection and ineffective treatment, such as abnormalities of the urinary tract, urinary obstruction, or diabetes. It can also mean there is severe involvement of the kidney, for example, abscess formation, obstruction, or enlarged kidney, or gas is seen in the kidney by an imaging study, such as a CT scan. In these situations, the symptoms may be more severe and less responsive to usual treatments.

A chronic kidney infection may refer to a recurring kidney infection that could be a result of a kidney stone obstructing the ureter or other structural abnormalities in the ureters . These conditions are usually associated with milder symptoms, but they may last longer.

The evaluation of complicated kidney infection and chronic kidney infection typically requires a more thorough evaluation and more extensive testing such as CT scans and X-rays.

Kidney infections can be quite painful and require prompt evaluation and treatment. If your infection isnt treated soon enough, it may permanently damage your kidneys or spread to your bloodstream, possibly leading to and the impairment of other vital organs.

High Blood Pressure Causes Kidney Damage

Kidney Disease High Blood Pressure Symptoms

High blood pressure can constrict and narrow the blood vessels in your kidneys, which reduces blood flow and stops the kidneys from working well. When this happens, the kidneys are not able to remove all wastes and extra fluid from your body. Extra fluid in the blood vessels can raise your blood pressure even more, creating a dangerous cycle, and cause more damage leading to kidney failure.

  • More than 1 in 7 adults in the US, or about 37 million people, may have chronic kidney disease
  • High blood pressure is the second leading cause of kidney failure in the US after diabetes
  • Approximately 1 in 5 adults in the US with high blood pressure may have CKD
  • Although Black or African American people make up about 13 percent of the population, they account for 35 percent of the people with kidney failure in the United States. These numbers are concerning and reflect some of the nonmedical reasons for the increased rates of high blood pressure in communities of color, which include where someone lives and works, the foods they eat, how much exercise they do, and if they are able to get the medical care they need.
  • High blood pressure and the early stages of CKD usually does not cause any physical symptoms, which is an important reason to have regular blood pressure screenings

What Causes A Kidney Infection

Kidney infections are caused by bacteria or viruses.

Scientists believe that most kidney infections start as a bladder infection that moves upstream to infect one or both of your kidneys. Most often, the infection is caused by bacteria that normally live in your bowel. The urinary tract has several ways to prevent infection from moving up the urinary tract. For example, urination most often flushes out bacteria before it reaches the bladder. Sometimes your body cant fight the bacteria and the bacteria cause a UTI. If you dont get medical treatment to stop the infection, the bacteria may infect your kidneys.

In some cases, your blood can carry bacteria or viruses from another part of your body to your kidneys.

Will My Child Need Other Tests

At follow-up visits, the doctor may do some additional tests to check the kidneys. These may include:

  • Glomerular filtration rate, or GFR, which tells the doctor how well the childs kidneys are working. GFR can be calculated from the results of a simple blood test for creatinine, a waste from muscle activity. When the kidneys are not working well, creatinine builds up to high levels in the blood.
  • Urine protein level. A higher level of protein in the urine means there is an increased chance that your childs kidney disease may get worse and that heart and blood vessel disease may develop. Treating high blood pressure may help to reduce your childs urine protein level.

How High Blood Pressure Can Cause Kidney Damage

Your heart, the key organ of the circulatory system, constantly pumps blood through your blood vessels. Good blood flow is essential for normal kidney function. Even minor blood flow problems can affect function and increase your risk of serious kidney damage.

Although it takes a certain amount of force to push blood through the blood vessels, the pressure inside the vessels sometimes becomes too high. High blood pressure can damage the blood vessels that lead to the kidneys, causing them to stiffen or narrow.

As a result, less blood reaches your kidneys, making it difficult for the organs to function properly. Tiny blood vessels inside the kidneys that filter blood may also be damaged.

Blood Pressure Fast Facts

  • The top number in a blood pressure measurement is called the systolic pressure. This measures the force of blood against the walls of the arteries when the heart is pumping. The lower number is called the diastolic pressure. This measures the force of the blood when the heart is between beats. Both numbers are important and need to be controlled.
  • In 2017, the American College of Cardiology and the American Heart Association published new guidelines for hypertension management and defined high hypertension as a blood pressure at or above 130/80 mm Hg. Stage 2 hypertension is defined as a blood pressure at or above 140/90 mm Hg
  • Nearly half of all adults in the US have high blood pressure
  • Only about 1 out of every 4 people with high blood pressure have their condition under control

What Are The Signs And Symptoms Of High Blood Pressure

Most people with high blood pressure have no symptoms. The only way to know whether a person’s blood pressure is high is to have a health professional measure it with a blood pressure cuff. The result is expressed as two numbers. The top number, called the systolic pressure, represents the pressure when the heart is beating. The bottom number, called the diastolic pressure, shows the pressure when the heart is resting between beats. A person’s blood pressure is considered normal if it stays at or below 120/80, which is commonly stated as “120 over 80.” People with a systolic blood pressure of 120 to 139 or a diastolic blood pressure of 80 to 89 are considered prehypertensive and should adopt lifestyle changes to lower their blood pressure and prevent heart and blood vessel diseases. A person whose systolic blood pressure is consistently 140 or higher or whose diastolic pressure is 90 or higher is considered to have high blood pressure and should talk with a doctor about the best ways to lower it.

Early kidney disease is a silent problem, like high blood pressure, and does not have any symptoms. People may have CKD but not know it because they do not feel sick. A person’s glomerular filtration rate is a measure of how well the kidneys are filtering wastes from the blood. GFR is estimated from a routine measurement of creatinine in the blood. The result is called the estimated GFR .

Symptoms of advanced kidney disease can include

  • loss of appetite, nausea, or vomiting
  • drowsiness, feeling tired, or sleep problems
  • headaches or trouble concentrating

Kidney Disease And High Blood Pressure: How Are They Related

Your kidneys and blood vessels work in tandem. Together with the blood vessels and circulatory system, the kidneys filter out toxins and deliver essential nutrients throughout the body. When the blood vessels become damaged, the kidneys are unable to do their job properly. This is why high blood pressure is one of the leading causes of kidney disease and kidney failure. Continue reading to learn more about how kidney disease and high blood pressure are related.

How the kidneys work

The kidneys are essential organs of the body that are approximately the size of your fist. You have one of them right below each side of the rib cage next to the spine. Blood flows into the kidneys where it goes through a filtering process.

The kidneys are made up of numerous filtering units that help filter the blood. These filtering units are called nephrons. Within the nephron are the glomerulus, a tubule and important blood vessels, including the renal artery and renal vein.

Blood from the renal artery flows into the glomerulus, which allows smaller molecules like toxins and nutrients to pass through to the tubule. The tubule then allows water and important nutrients to be reabsorbed back into the blood and returned to the rest of the body via the renal vein. The fluid and waste that is left in the tubule becomes urine and is excreted from the body.
