Life Expectancy of Patients with Chronic Renal Failure

Chronic Renal Failure describes a serious and progressive medical condition affecting your kidneys, and it can be caused by diabetes or hypertension. Chronic Renal Failure usually causes no signs or symptoms and is often detected being done for another condition. Patients who are suffering from Chronic Renal Failure means the conditions have been developed to the end stage of kidney disease. Well, in this case, how long should the patients expect their own life expectancy?

According to the renal pathological research, before the condition develops to uremia and CFR (glomerular filtration rate) higher than 5%, you still have a chance to get better.

As for the exact life expectancy, it depends on specific situations. Hypothetically, a patient with Chronic Renal Failure is detected in early stage with a relative low creatinine. He may have a good chance to recover. In simple and popular language, in early stage of Chronic Renal Failure, the condition can get better through appropriate treatment while the inadequate treatment would lead to uremia which can be harder to remedy. Taking what kind of treatment depends on not only your own condition but also your physical condition. Moreover, keeping your body warm and your mind peaceful, taking a healthy diet also can help you live a relative good quality of life. Building confidence is one of the vital factors which can help you slow down the progression, meanwhile, speed up the process of recovery.

When the condition has been in an on-going down-trend and finally developed to end-stage renal failure (ESRF), we should take effective therapy right now, furthermore, repair kidney function as much as possible. There are chances to bring the condition under control and improve patients’ life quality at the same time.

Diagnostic Criteria of Chronic Renal Failure in Children

Chronic Renal Failure poses a great damage and greatly affects the quality of life in children. By knowing the diagnostic criteria, you can have a better understanding of the disease.

Age range: 0-14 years old.

Creatinine clearance rate (CCr) ﹤50 ml / (min·1.73 m)

Course of disease is in line with the following conditions:

Those with confirmed acute nephritis history more than 1 year; those with hidden onset more than 1/2 years; or those patients with renal failure who are caused by chronic pathological changes or genetic renal diseases.

Patients with confirmed renal history over one year or hidden onset more than 6 months or course of diseases less than 6 months, but the renal pathological test and clinical test (blood, routine urine test, calcium and phosphorus metabolism and B ultrasonic for kidneys etc.) manifest the renal diseases has enter into a chronic phase, features are same as CRF.

Renal function condition: blood urea nitrogen (BUN)﹥8.57 mmol / L( increase with SCr parallelly); serum creatinine rate (SCr) ﹥176.8 pmoL/L.

Have sign or symptoms such as renal anemia, slow-growing, hypertension and uremia etc.
According to a complete data shows that gender ratio is 1.49/1; average age of onset is 8.2 years old; average course before diagnosis is 2.5 years. Main primary diseases are chronic nephritis and renal syndromes which account for 52.7%; congenital or hereditary diseases account for about 1/4, which mainly are renal dysplasia and renal cystic disease. Primary clinical features at time of diagnosis are anemia, gastrointestinal reaction, edema, hypertension and growth retardation etc.

Treatment

Relieve the uremia symptoms and protect remaining renal function.

Place emphasis on nutrition in children with CRF. Do our best to provide enough caloric supply for those children. Daily caloric supply should not less than normal same-age children. Low-protein diet (LPD) becomes the foundation among nutrition issues. Suggestion: LPD begins when GRF﹤60ml / (min·1.73 m2); ﹤1 years old, 1.8g / (kg·d); 1-2 years old, 1.0-1.5g / (kg·d); 2-16 years old, 1 g / (kg·d); serious cases 0.6-1.0 g / (kg·d).

Add essential amino-acid, ketonic acid, water soluble vitamin (VitB, VitC and folic acid) on the basis of LPD.

We suggest that protein intake should be restrained when GRF down to 50% or even less.
Patients with GFR﹤5ml/min·1.73 m, supply 0.6g/kg·d protein including high quality protein0.35 g/kg·d.

Patients with no dialysis and GFR﹤25ml/min·1.73 m, if they are lack of caloric, provide 0.75 g/kg·d protein to them.

Patients with GRF 5-25ml/min·1.73 m, add 0.3 g/kg·d essential amino-acid or ketoanaloge KA.
For patients with hemodialysis: provide 1.2 g/kg·d protein.

Can Pyelonephritis Cause Chronic Renal Failure

Pyelonephritis is a type of urinary tract which affects one or both kidneys. It may cause permanent kidney damage and chronic renal failure. Therefore, you should not ignore it and should have treatment immediately after its diagnosis.

Pyelonephritis is mainly due to bacterium or virus infecting the kidneys. The bacterium Escherichia coli is the common cause for this problem. The bacteria and viruses can travel from bladder to kidneys, leading to kidney infections.

In normal condition, the urine flow from the kidneys to the bladder. However, if some people have a structural defect of the urinary tract, a kind stone, or enlarged prostate, it may cause urine to flow back up, or reflux into one or both kidneys. As the urine contain bacteria and virus, this part of people are at risk of developing pyelonephritis. Also, the patients with bladder infection are more likely to develop pyelonephritis. If the infection is not controlled, it may cause progressive kidney damage and Chronic Renal Failure.

* It can cause persistent kidney inflammation that can scar the kidneys and may lead to chronic renal failure.

* Pyelonephritis may cause building up of urine in urinary tract. Consequently, the pressure in kidneys will increase significantly and compress kidney tissues and cells, leading to renal ischemia and anoxia. Then, it can cause sclerosis and necrosis of kidney tissues.

Therefore, early inspection and treatment of pyelonephritis is very important to prevent it from developing into chronic renal failure.

1. The patients usually are suggested to drink more water to flush out the virus and bacteria in the urinary tract by producing urine.

2. Antibiotics are usually prescribed to control the infection. Thus, it can prevent the virus or bacteria from traveling to other body parts in blood stream and prevent more serious kidney inflammation.

3. If pyelonephritis has caused kidney impairment, the above treatment methods are not enough to control the condition. Along with controlling the inflammation of kidneys, relative therapy should be adopted to prevent further kidney scarring and improve renal function.
