Anuria is a serious medical condition in which the body produces little to no urine. In simple terms, anuria meaning is the complete absence or near absence of urine output, usually less than 100 milliliters in 24 hours. Urine is how the body removes waste and extra fluids. When urine stops or becomes extremely low, it signals that the kidneys may not be working properly.
Understanding what is anuria, its causes, anuria symptoms, and anuria treatment is very important. Early medical care can protect kidney function and prevent life threatening complications.
What Is Anuria?
What is anuria? Anuria is a condition where the kidneys fail to produce enough urine. It is different from oliguria, which means reduced urine output. In anuria, urine output is almost completely stopped.
The kidneys filter waste from the blood and convert it into urine. When this process is disrupted, waste builds up in the body. This can quickly affect other organs such as the heart, lungs, and brain.
Anuria can occur suddenly or develop gradually due to chronic kidney disease. It is considered a medical emergency and needs immediate evaluation.

How the Kidneys Work
To understand anuria, it helps to know how healthy kidneys function.
The kidneys:
• Filter waste and toxins from the blood
• Balance fluids in the body
• Control blood pressure
• Maintain electrolyte balance
• Produce hormones for red blood cell production
When the kidneys are damaged due to kidney disease or injury, urine production decreases. In severe cases, this leads to anuria.
Causes of Anuria
There are several causes of anuria. Doctors usually group them into three main categories.
1. Pre renal causes
These occur when blood flow to the kidneys is reduced.
Common reasons include:
• Severe dehydration
• Heavy blood loss
• Heart failure
• Severe infections
• Shock
When blood does not reach the kidneys properly, they cannot produce urine.
2. Renal causes
These are problems directly affecting the kidneys.
Examples include:
• Acute kidney injury
• Chronic kidney disease
• Severe infections of the kidney
• Toxic drug reactions
• Autoimmune disorders
Chronic kidney disease is a major risk factor. If left untreated, kidney disease can gradually worsen and result in anuria.
3. Post renal causes
These occur when urine flow is blocked after it leaves the kidneys.
Common causes include:
• Kidney stones
• Enlarged prostate in men
• Tumors in the urinary tract
• Blood clots in the bladder
A blockage prevents urine from exiting the body, leading to anuria.
Anuria in Adults
Anuria in adults is often linked to chronic kidney disease, diabetes, high blood pressure, or severe infections. Adults with uncontrolled kidney disease are at higher risk.
Symptoms may appear suddenly in cases of acute kidney injury. In other cases, people with long standing kidney disease may notice gradual changes before complete anuria develops.
Early diagnosis is critical to prevent permanent kidney damage.
Anuria in Children
Anuria in children is rare but very serious. It may result from:
• Severe dehydration due to diarrhea or vomiting
• Congenital kidney abnormalities
• Urinary tract blockage
• Severe infections
Children require immediate medical care if there is no urine output for several hours. Pediatric nephrologists at Continental Hospitals provide specialized care for anuria in children.
Anuria Symptoms
Anuria symptoms can vary depending on the cause. The most obvious sign is no urine output or extremely low urine output.
Other common anuria symptoms include:
• Swelling in legs, feet, or face
• Shortness of breath
• Fatigue
• Confusion
• Nausea and vomiting
• Irregular heartbeat
• Chest pain
Because waste builds up in the bloodstream, the body becomes toxic. This condition can quickly become life threatening if not treated.
If you or a loved one notices sudden absence of urine, seek immediate medical attention.
How Is Anuria Diagnosed?
Doctors use several tests to confirm anuria and identify the cause.
Diagnostic methods include:
• Physical examination
• Blood tests to check kidney function
• Urine tests if any urine is present
• Ultrasound of the kidneys and bladder
• CT scan to detect blockage
• Electrolyte level testing
Early and accurate diagnosis helps doctors decide the best anuria treatment plan.
Anuria Treatment
Anuria treatment depends on the underlying cause. The primary goal is to restore urine flow and protect kidney function.
Treatment options include:
Treating dehydration or shock
• Intravenous fluids
• Blood transfusion if needed
Managing kidney injury
• Stopping harmful medications
• Controlling blood pressure
• Treating infections
Removing blockages
• Catheter insertion
• Surgery for kidney stones
• Procedures to remove tumors
Dialysis
In severe cases where the kidneys cannot function, dialysis may be required. Dialysis helps remove waste and extra fluids from the blood.
Prompt anuria treatment can prevent permanent kidney damage. Delayed care increases the risk of complications.
Complications of Anuria
If not treated quickly, anuria can lead to serious complications such as:
• Severe electrolyte imbalance
• Heart rhythm problems
• Fluid buildup in lungs
• Permanent kidney failure
• Multi organ failure
These complications highlight why early medical attention is critical.
Preventing Anuria
While not all cases can be prevented, you can reduce risk by:
• Staying well hydrated
• Managing diabetes and high blood pressure
• Avoiding excessive use of painkillers
• Getting regular kidney function tests
• Seeking early treatment for urinary problems
People with chronic kidney disease should follow their doctor’s advice strictly to prevent worsening kidney disease and anuria.
