Several kidney diseases can be diagnosed and treated, including acute kidney injury, chronic prerenal kidney disease, and kidney infections. Depending on the type of kidney disease, treatment options can include medications, surgery, and other treatment options. Fortunately, some of these diseases can be treated and even reversed.
Acute kidney injury
Previously known as acute renal failure, acute kidney injury (AKI) is a condition that results in an abrupt decrease in the ability of the kidneys to remove waste products from the blood. It is a common condition but can be reversible.
AKI can be caused by infections, stress from elsewhere, or medications. Treatment is necessary to minimize the damage and reduce the severity of the symptoms. The most common causes are infections and hypovolaemic shock.
AKI is usually detected through blood tests in patients who are unwell. The severity of AKI can range from mild to severe. Survivors of AKI have a poor prognosis.
AKI is often associated with increased post-hospitalization mortality. Patients who are diagnosed with AKI may require kidney replacement therapy. The decision to start kidney replacement therapy requires a nephrologist’s expertise.
Treatment for AKI may include fluid resuscitation, renal replacement therapy, and kidney transplantation. However, these treatments usually only last for a few weeks. It is important to evaluate kidney function daily while hospitalized, and start therapy only after kidney function has stabilized.
The RIFLE (Renal Injury Fighting Life-Shortening) classification encompasses the full spectrum of AKI. The RIFLE classification uses changes in serum creatinine as a measure of the extent of AKI.
AKI can be classified into three stages: mild, moderate, and severe. Mild AKI involves minimal kidney cell damage. Moderate AKI involves a minimal or moderate decline in urinary output. It can be detected by blood tests or urine output. Severe AKI involves renal cell degeneration or necrosis. It can be detected by blood tests or ultrasound.
AKI may be reversible, but it is usually fatal. AKI can be caused by infection, surgery, or other illnesses.
Symptoms of kidney stones include pain, nausea, vomiting, and blood in the urine. Some stones can be passed spontaneously, while others may require surgery.
A primary care physician can diagnose and treat kidney stones. They will examine your urine and urine culture and may order imaging tests to assess your kidneys and bladder. They may also recommend preventive measures. They may prescribe medication or lifestyle changes to prevent future stones.
Kidney stones are more common in people with certain medical conditions. These include high levels of salt, calcium, or uric acid in the urine. Other conditions that increase the risk of kidney stones include high blood pressure, diabetes, gout, and gastrointestinal problems.
Kidney stones can be prevented by maintaining a healthy diet. Limit your intake of foods that are high in sodium or calcium oxalate. You should also consume plenty of water and avoid alcoholic beverages.
Some people may have a condition called metabolic syndrome, which is characterized by abnormal cholesterol levels, high blood pressure, excess body fat, and high blood sugar. They may also have digestive disorders that impair the absorption of calcium.
Other conditions that increase the risk of kidney stones are gastrointestinal problems, such as diarrhea, and a diet high in oxalate. Pregnant women are also at greater risk of developing stones. They are prone to developing stones because of the increasing pressure on the expanding uterus.
Kidney stones can cause infection, swelling, and loss of renal function. Acute management of kidney stones usually involves hydration, antibiotics, and pain control. However, larger stones may require surgical intervention.
To prevent kidney stones, a high-protein diet should be kept to less than 30% of the total calorie intake. You should drink at least three liters of liquid daily.
Having a kidney infection can be very painful and cause a lot of discomforts. You will experience symptoms such as back pain, chills, nausea, and fever. Your doctor may prescribe antibiotics or pain medication to reduce the pain.
There are several causes of kidney infections. Most of these infections are caused by bacteria. The main culprits are E. coli and viruses. These bacteria multiply in the urethra and then travel through the bladder.
If you are suffering from kidney infections you should see a physician at the first sign of infection. You may need to take an antibiotic, drink plenty of fluids, or have surgery. The symptoms of a kidney infection include pain when urinating, back pain, nausea, and fever.
The bacteria that cause a kidney infection usually spread from the urethra to the kidney. You can avoid a kidney infection by keeping your urethra free of bacteria. Also, you can avoid infections by urinating after a bowel movement. You can also try urinating every few hours to flush the bacteria out of your body.
If you have a kidney infection you may have blood in your urine. Blood in the urine can be an unpleasant odor and discoloration. In addition, you may have abdominal pain.
Symptoms vary from person to person. If you are young, you may not notice any symptoms. For people with a weak immune system, you may not even know you have a kidney infection.
Some people may experience a bloodstream infection called sepsis. This is very dangerous and can result in kidney failure if not treated immediately.
Your physician will use the physical, lab, and imaging tests to diagnose your kidney infection. Imaging tests can include CT scans, ultrasound, and MRI scans. These tests will provide images of the kidneys and the urethra. You may also have blood cultures sent to the laboratory to detect the type of bacteria in your urine.
Polycystic kidney disease
Known as PKD, polycystic kidney disease is a genetic disease that causes cysts to form in the kidney. The cysts are fluid-filled sacs that gradually take over the kidney. This causes a decrease in kidney function and often leads to kidney failure.
Polycystic kidney disease can go undetected for years, but symptoms usually begin in middle adulthood. Patients who have polycystic kidney disease are more likely to develop aneurysms. These balloon-like bulges in the blood vessels can cause bleeding in the brain if they rupture.
People with ADPKD, or autosomal dominant polycystic kidney disease, usually have kidney failure by the age of 30. People with this disease usually have cysts in both kidneys, which can also develop in the liver, pancreas, and arachnoid membrane. This condition may also lead to complications with the heart, blood vessels, and connective tissue.
ADPKD is usually caused by two genetic mutations. The mutations, PKD1, and PKD2 occur on chromosomes 16 and 4. People with this type of polycystic kidney disease have a 25% chance of having the disease.
People with this disease are at a higher risk of developing complications such as preeclampsia and preterm labor. The disease may also lead to abdominal hernias, diverticulosis, and heart valve problems.
The disease is usually diagnosed through an imaging study of the kidneys. This is not a routine test, and it requires a radiologist who is trained in this technique. The test can also identify large cysts that may need to be drained.
People who have the disease may also have high blood pressure. Managing blood pressure can help prevent complications from polycystic kidney disease. A low-salt diet, including whole grains, fruits, and vegetables, can help control high blood pressure. Untreated high blood pressure can increase the risk of strokes, heart disease, and kidney damage.
Chronic prerenal kidney disease
Unlike acute kidney injury, which is defined by its symptoms, chronic prerenal kidney disease does not always have visible symptoms. It is characterized by a loss of function or impairment in the kidney and/or heart. Symptoms may be minor or pronounced, and may be triggered by a variety of factors.
The kidney has a variety of roles and functions, including filtering and regulating blood pressure. As a result, it is important to understand the mechanisms that underlie kidney failure. One of these mechanisms is the volume of filtrate passing the glomerular filtration barrier. Usually, this is measured by serum levels of endogenous filtration markers.
The best overall index of kidney function is the glomerular filtration rate (GFR). It is difficult to measure this directly, but serial serum creatinine measurements are often the most reliable measure. Similarly, urine output is a useful measure of tubular function. If the glomerulus Aerus is blocked, you may require a nephrostomy.
Another useful measure of kidney function is the rate at which urine exits the body. A urinary catheter can be used to monitor this metric. If the output is surprisingly low, a diuretic may be required to alleviate this symptom.
As a matter of fact, the most common cause of acute kidney injury is dehydration and seps. Similarly, the most common cause of postrenal AKI is benign prostatic hyperplasia (BPH). A bladder stone may also trigger the postrenal AKI phenomenon.
The best way to manage AKI is to find out which of these two culprits is responsible. Fortunately, there are many tools to do this. A central venous catheter is one such tool, while a urine output monitor is another. Aside from monitoring the output, a catheter may also be used to monitor volume status, which is a valuable measure of kidney function.
