Chronic renal failure : Definition, Etiopathogenesis, Symptoms, Treatment And MCQs for NEET, GPAT, CSIR NET JRF
“Chronic renal failure is a syndrome characterized by progressive and irreversible deterioration of renal function due to the destruction of the renal parenchyma.”
“Major problem in CRF is of acidosis with the development of biochemical azotaemia and clinical uremia syndrome.”
ETIOPATHOGENESIS :-
1.] All the chronic nephropathies can lead to CRF.
2.] The types of disease leading to CRF can generally be classified into two major groups :
(A) DISEASE CAUSING GLOMERULAR PATHOLOGY :
- Glomerular filtration is being changed due to glomerular destruction and leads to the development of nephrotic syndrome.
- Primary glomerular pathology the major cause of CRF is chronic glomerulonephritis, usually initiated by various glomerulonephritis.
- Systemic glomerular pathology, certain conditions originate outside the renal system but induce change in the nephron secondarily.
(B) DISEASE CAUSING TUBULOINTERSTITIAL PATHOLOGY :
- Damage to tubulointerstitial tissue result in alteration in reabsorption and secretion of important constituent leading to secretion of large volume of dilute urine.
- Tubulointerstitial disease can be categorized according to initiating etiology into four groups : Vascular causes, Infectious causes, Toxic causes and Obstructive causes.
SYMPTOMS :-
Symptoms of chronic renal failure are as follow :
- Fatigue.
- High blood pressure.
- Loss of appetite.
- Kidney damage.
- Abnormal heart rhythm.
- Malaise.
- Water – electrolyte imbalance.
- Fluid in the lungs.
- Kidney failure.
- Swelling.

TREATMENT :-
- Certain medications are given to the patients suffering from CRF like vitamins, calcium reducer, bone marrow stimulant, diuretics and the dietary supplements.
- Certain medical procedures like peritoneal dialysis, hemofilteration and dialysis were also given to the patients.
- In some condition kidney transplant can also be considered as an option.
