Acute Renal Failure
What is Acute Renal Failure?
Acute Kidney Injury is a serious condition where the kidneys suddenly lose their ability to filter waste and excess fluid from the blood which happens suddenly in a short period of time usually over hours to days. When the kidneys are not working properly, harmful toxins and waste products and excess fluid can build up in the body. This leads to health issues like swelling, high blood pressure, and problem with breathing.
Types Of Acute Kidney Disease:
Prerenal Causes (Before the Kidneys)
It comes from the decrease of blood supply to the kidneys for the most part due to bleeding, dehydration, low blood pressure, heart problems, infections, burns, liver failure, or NSAID use.
Intrinsic (Renal) Causes (Within the Kidneys)
The causes that arise due to the direct injury to the kidneys, such as blood clots, immunities (like glomerulonephritis), lupus, infections, toxins, drugs, or muscle breakdown (rhabdomyolysis)
Postrenal Causes (After the Kidneys):
The obstruction of the urine flow from the kidneys to the bladder can be caused by different reasons: kidney stones, the prostate complications, urinary clots, cancers, or/and the malfunction of the nerves that control the bladder.
Symptoms of Acute Renal Failure:
Acute Kidney Injury (AKI) can present with various symptoms, but it’s important to note that some people might not notice any signs, especially early on. If you experience any of these, it’s wise to consult a kidney specialist , particularly if you have risk factors like diabetes or high blood pressure.
- Urinary Changes: Making less urine than usual or no urine at all.
- Fluid Retention: Swelling in the legs, ankles, or feet, and sometimes shortness of breath.
- General Malaise: Fatigue, tiredness, weakness, drowsiness, and loss of appetite.
- Other Signs: Confusion, mood changes, nausea, vomiting, diarrhea, dehydration,
- flank pain, belly pain, chest pain or pressure seizures or coma.
Treat Underlying Causes
Eliminate infections, treat dehydration and correct hypotension, and treat urinary tract obstruction surgically
Fluid & Electrolyte Management
We need to reduce Sodium, potassium, and fluids must be balanced to avoid complications.
Medications
Diuretics and antibiotics if there is evidence of sepsis and inotropic support in case of hypotension
Dialysis
If the kidneys don’t sufficiently remove toxins, then temporary dialysis in the form of SLEDD / CRRT may be required.
Acute Renal Failure can occur for several reasons, including:

Everything you need to know about kidney diseases
Acute kidney disease, also referred to as acute kidney injury (AKI), occurs when your kidneys suddenly fail to function normally. This may occur within a few hours or days. Some of the common causes include:
- Dehydration (failure to drink sufficient fluids)
- Infections
- Some medications (such as painkillers or antibiotics)
- Abrupt reduction in blood supply to the kidneys (because of heart failure, shock, or blood loss)
- Blockages (such as kidney stones or prostate enlargement)
Acute Kidney Injury (AKI):
- Occurs suddenly (in hours or days)
- Can be temporary and can clear up if treated promptly
- Tends to result from sudden events such as dehydration or infection
Chronic Kidney Disease (CKD):
- Develops over months or years
- Typically, cannot be cured, but can be controlled
- Typically results from long-term conditions such as diabetes or high blood pressure
Yes! Treatment is aimed at removing the cause and supporting the kidneys as they recover. This may involve:
- Providing IV fluids for dehydration
- Halting harmful medications
- Treating infections
- Controlling blood pressure
In advanced cases, temporary dialysis can be required
Kidney issues usually don’t have symptoms immediately, but early signs can be:
- Feeling more weak or tired than normal
- Swelling in your face, feet, or legs
- Urination changes (peeing more or less, or dark/frothy pee)
- Loss of appetite or nausea
- Difficulty concentrating
- High blood pressure
If you observe these signs, it’s critical to consult a doctor and have yourself checked.
