Acute kidney failure is mainly caused by age, the older you are, the higher the risk of acute kidney failure. Acute kidney failure has a high mortality rate. Therefore, early diagnosis, early detection as well as proper treatment play a very important role.

The state of acute renal failure progresses through 4 stages including:
Initiation phase Urinary incontinence, anuria stage Recurrent urinary stage Recovery phase The onset of acute renal failure is rapid, long and short. on a case-by-case basis and for each cause. The stage of urinary frequency, anuria may progress slowly, the patient has symptoms of urinary less and then anuria, but the cause of anuria may occur suddenly. This is a rather dangerous stage of acute kidney failure. Patients will experience disturbances in water, electrolytes, acid-base balance, kidney edema depending on the degree, depending on the amount of water that has been taken into the body before. Even the risk can lead to generalized edema, multi-membrane effusion.

If not resolved and treated promptly, people with acute kidney failure will have high blood pressure, pericardial effusion, causing acute cardiac tamponade. Hyperkalemia causes rapid cardiac arrhythmias, when unbearable, cardiac arrest leads to death.
Besides, blood sodium and calcium often decrease, blood calcium decrease will lead to the risk of hyperkalemia. Acidosis is an unavoidable problem due to the accumulation of stable acids in the presence of oliguria - anuria, decreased bicarbonate, decreased residual alkalinity, decreased blood pH, the patient will have dyspnea, rapid and deep breathing, disease worsens and leads to death.
Cardiovascular disorders in acute renal failure often appear when blood potassium is high, heart failure is one of the consequences of fluid retention and electrolyte disturbances in acute renal failure. Some cases present with shortness of breath, nausea, coma, convulsions and bleeding rapidly, which is life-threatening quickly and unpredictably.
With timely intervention, the patient will recover with normal urination and then gradually recover. Recovery is fast and slow depending on the case. The ability of the renal tubules to concentrate urine sometimes takes several years to completely recover, the glomerular filtration rate recovers faster than usual, and by the second month, it may be normal. The slow recovery depends on the cause leading to the acute renal failure, and the treatment intervention in the acute renal failure stage, the average treatment regimen is about 4 weeks.
However, according to doctors, the prognosis of acute kidney failure depends on many different factors such as the cause of the disease, the initial treatment conditions, as well as the treatment method. Patients with acute renal failure need to be treated promptly and accurately with active measures. With modern treatment methods in medicine today, acute kidney failure can be completely controlled, limiting mortality.
In which kidney scintigraphy is a highly effective method of diagnosis and treatment of acute renal failure. This is a technique to evaluate kidney function using modern high-precision recording devices. Kidney scintigraphy produces high-quality images that show the exact condition of the kidney and kidney failure in order to have the right and most effective treatment.

Patients with signs of renal failure, acute as well as chronic renal failure should be consulted and indicated for appropriate renal radiotherapy to combine effective treatment. Vinmec Times City International Hospital uses the SPECT/CT Discovery NM/CT 670 Pro equipment system, with the most modern 16-row CT from the world's leading medical equipment company GE Healthcare (USA), for High-quality images help to diagnose diseases that need to be investigated early.
