The common diagnoses for kidney disease are often based on the underlying cause and the stage of kidney damage. Here are some of the most frequent diagnoses: Chronic Kidney Disease (CKD): This is a general term for the gradual loss of kidney function over time. It is often diagnosed based on blood tests (measuring creatinine and estimating glomerular filtration rate - eGFR) and urine tests (checking for protein). CKD is typically categorized into five stages based on eGFR. Diabetic Nephropathy: This is kidney damage resulting from diabetes. It's diagnosed by detecting protein (albumin) in the urine and a declining eGFR in individuals with diabetes. Hypertensive Nephrosclerosis: This refers to kidney damage caused by high blood pressure. Diagnosis involves identifying kidney damage in someone with a history of hypertension, often with a reduced eGFR and protein in the urine. Glomerulonephritis: This is a group of diseases that cause inflammation and damage to the glomeruli (the filtering units of the kidneys). Diagnoses are often made through kidney biopsy, along with blood and urine tests. There are many specific types, such as IgA nephropathy or lupus nephritis. Polycystic Kidney Disease (PKD): This is an inherited disorder where cysts develop in the kidneys, causing them to enlarge and lose function. Diagnosis is typically made using imaging tests like ultrasound, CT scans, or MRI. Acute Kidney Injury (AKI): This is a sudden and often reversible loss of kidney function that occurs over hours or days. It's diagnosed based on a rapid rise in serum creatinine levels or a significant decrease in urine output. AKI can be caused by various factors, including severe dehydration, infections, certain medications, or blockages. Nephrotic Syndrome: This is a collection of symptoms that indicate kidney damage, including high levels of protein in the urine (proteinuria), low levels of protein in the blood (hypoalbuminemia), swelling (edema), and high cholesterol. It can be caused by various underlying kidney diseases. Kidney Stones (Nephrolithiasis): While not always causing chronic kidney disease, recurrent or severe kidney stones can lead to kidney damage and are a common diagnosis related to kidney health. Diagnosis is usually made with imaging tests like CT scans or X-rays. Urinary Tract Obstruction: Blockages in the urinary tract (e.g., from enlarged prostate, kidney stones, or tumors) can cause damage to the kidneys. Diagnosis involves imaging and assessing urine flow.
