The kidneys are a pair of bean-shaped organs on either side of your spine, below your ribs and backside your abdomen. Each kidney is about four or 5 inches long, roughly the size of a large fist.

The kidneys' job is to filter your blood. They remove wastes, control the body's fluid residuum, and go on the right levels of electrolytes. All of the blood in your body passes through them about xl times a day.

Blood comes into the kidney, waste gets removed, and common salt, h2o, and minerals are adjusted, if needed. The filtered blood goes dorsum into the body. Waste matter gets turned into urine, which collects in the kidney'southward pelvis -- a funnel-shaped structure that drains down a tube called the ureter to the bladder.

Each kidney has around a million tiny filters called nephrons. Y'all could take just 10% of your kidneys working, and you may not detect any symptoms or problems.

If blood stops flowing into a kidney, part or all of it could die. That can lead to kidney failure.

Kidney Weather

Pyelonephritis (infection of kidney pelvis): Bacteria may infect the kidney, usually causing back pain and fever. A spread of leaner from an untreated bladder infection is the most common cause of pyelonephritis.
Glomerulonephritis: An overactive immune system may assault the kidney, causing inflammation and some damage. Blood and protein in the urine are common problems that occur with glomerulonephritis. It tin can also event in kidney failure.
Kidney stones (nephrolithiasis): Minerals in urine course crystals (stones), which may grow large plenty to block urine period. It's considered i of the most painful conditions. Most kidney stones laissez passer on their ain, but some are likewise large and need to be treated.
Nephrotic syndrome: Damage to the kidneys causes them to spill large amounts of protein into the urine. Leg swelling (edema) may be a symptom.
Polycystic kidney illness: A genetic condition resulting in large cysts in both kidneys that hinder their work.
Acute renal failure (kidney failure): A sudden worsening in how well your kidneys work. Dehydration, a blockage in the urinary tract, or kidney damage can cause acute renal failure, which may be reversible.
Chronic renal failure: A permanent partial loss of how well your kidneys work. Diabetes and high claret pressure level are the most common causes.
End-stage renal disease (ESRD): Consummate loss of kidney strength, ordinarily due to progressive chronic kidney illness. People with ESRD require regular dialysis for survival.
Papillary necrosis: Severe damage to the kidneys can cause chunks of kidney tissue to interruption off internally and clog the kidneys. If untreated, the resulting harm can lead to total kidney failure.
Diabetic nephropathy: High blood sugar from diabetes progressively amercement the kidneys, somewhen causing chronic kidney disease. Protein in the urine (nephrotic syndrome) may likewise event.
Hypertensive nephropathy: Kidney damage caused by loftier blood force per unit area. Chronic renal failure may eventually result.
Kidney cancer: Renal prison cell carcinoma is the almost mutual cancer affecting the kidney. Smoking is the most mutual cause of kidney cancer.
Interstitial nephritis: Inflammation of the connective tissue inside the kidney, often causing acute renal failure. Allergic reactions and drug side furnishings are the usual causes.
Minimal alter illness: A form of nephrotic syndrome in which kidney cells look near normal nether the microscope. The disease can cause meaning leg swelling (edema). Steroids are used to treat minimal modify illness.
Nephrogenic diabetes insipidus: The kidneys lose the ability to concentrate the urine, commonly due to a drug reaction. Although information technology's rarely dangerous, diabetes insipidus causes constant thirst and frequent urination.
Renal cyst: A hollowed-out space in the kidney. Isolated kidney cysts often happen as people historic period, and they almost never crusade a problem. Complex cysts and masses tin be cancerous.

Kidney Tests

Urinalysis: A routine exam of the urine by a machine and often by a person looking through a microscope. Urinalysis can help detect infections, inflammation, microscopic bleeding, and kidney impairment.
Kidney ultrasound: A probe placed on the skin reflects sound waves off the kidneys, creating images on a screen. Ultrasound can reveal blockages in urine flow, stones, cysts, or suspicious masses in the kidneys.
Computed tomography (CT) browse: A CT scanner takes a serial of Ten-rays, and a figurer creates detailed images of the kidneys.
Magnetic resonance imaging (MRI) scan: A scanner uses radio waves in a magnetic field to make high-resolution images of the kidneys.
Urine and blood cultures: If an infection is suspected, cultures of the blood and urine may identify the leaner responsible. This tin can help target antibiotic therapy.
Ureteroscopy: An endoscope (flexible tube with a camera on its finish) is passed through the urethra into the bladder and ureters. Ureteroscopy mostly cannot reach the kidneys themselves, but tin assist treat conditions that also affect the ureters.
Kidney biopsy: Using a needle inserted into the back, a small-scale slice of kidney tissue is removed. Examining the kidney tissue under a microscope may assistance diagnose a kidney problem.

Kidney Treatments

Antibiotics: Kidney infections acquired by bacteria are treated with antibiotics. Often, cultures of the blood or urine can help guide the pick of antibiotic therapy.
Nephrostomy: A tube (catheter) is placed through the pare into the kidney. Urine then drains direct from the kidney, bypassing whatever blockages in urine flow.
Lithotripsy: Some kidney stones may be shattered into small pieces that can pass in the urine. Nearly oftentimes, lithotripsy is washed by a machine that projects ultrasound shock waves through the body.
Nephrectomy: Surgery to remove a kidney. Nephrectomy is performed for kidney cancer or severe kidney damage.
Dialysis: Artificial filtering of the blood to replace the work that damaged kidneys can't do. Hemodialysis is the most common method of dialysis in the U.Due south.
Hemodialysis: A person with consummate kidney failure is connected to a dialysis automobile, which filters the blood and returns it to the trunk. Hemodialysis is typically done 3 days per week in people with ESRD.
Peritoneal dialysis: Placing large amounts of a special fluid in the belly through a catheter allows the body to filter the blood using the natural membrane lining the abdomen. After a while, the fluid with the waste is drained and discarded.
Kidney transplant: Transplanting a kidney into a person with ESRD can restore kidney function. A kidney may exist transplanted from a living donor, or from a recently deceased organ donor.
