In Brazil, acute kidney failure is managed by urologists. Acute kidney failure (AKF), also known as acute kidney injury (AKI), is a sudden loss of kidney function that occurs over hours or days. This condition prevents the kidneys from filtering waste products from the blood, leading to a dangerous buildup of toxins.
Acute kidney failure (AKF) is a medical condition characterized by a rapid decline in kidney function, resulting in the kidneys' inability to filter waste and excess fluids from the blood. This leads to an accumulation of toxins and electrolytes in the body, disrupting normal bodily functions. AKF can occur due to reduced blood flow to the kidneys, direct damage to kidney tissues, or obstruction of the urinary tract. It is classified into three stages based on severity: risk, injury, and failure.
The key symptoms of Acute kidney failure are: Decreased urine output, Swelling in legs and ankles, Fatigue and weakness, Shortness of breath, Confusion or drowsiness.
Acute kidney failure is diagnosed through a combination of medical history, physical examination, and diagnostic tests. Doctors assess symptoms, review medications, and evaluate risk factors. Blood and urine tests are essential to measure kidney function and identify abnormalities. Imaging studies may be used to detect structural issues or blockages in the urinary tract. Early diagnosis is critical to prevent complications and guide treatment.
The prognosis for acute kidney failure depends on the underlying cause and the timeliness of treatment. Many patients recover fully with appropriate care, but severe cases may lead to chronic kidney disease or require long-term dialysis. Early diagnosis and adherence to treatment plans improve outcomes significantly.
A urologist specializes in diagnosing and treating kidney and urinary tract disorders. Consulting a urologist ensures accurate diagnosis and effective management of acute kidney failure.
