Anuria is a medical condition characterized by the absence of urine production. It is a severe form of oliguria, where the urine output is less than 100 milliliters per day. Anuria is a critical condition that requires immediate medical attention as it can indicate severe underlying health issues.
Causes[edit]
Anuria can be caused by various factors, including:
- Acute kidney injury (AKI)
- Chronic kidney disease (CKD)
- Severe dehydration
- Urinary tract obstruction
- Heart failure
- Sepsis
- Severe hypotension
Symptoms[edit]
The primary symptom of anuria is the complete absence of urine output. Other associated symptoms may include:
Diagnosis[edit]
The diagnosis of anuria involves several steps:
- Medical history and physical examination
- Blood tests to check for kidney function markers such as creatinine and blood urea nitrogen (BUN)
- Urinalysis
- Imaging studies like ultrasound or CT scan to identify any obstructions or abnormalities in the urinary tract
- Renal biopsy in certain cases
Treatment[edit]
The treatment of anuria depends on the underlying cause. Common treatment options include:
- Intravenous fluids for dehydration
- Dialysis for severe kidney failure
- Medications to manage heart failure or sepsis
- Surgical intervention to remove urinary tract obstructions
Prognosis[edit]
The prognosis of anuria varies depending on the underlying cause and the promptness of treatment. Early diagnosis and treatment are crucial for a better outcome.
