| Kidney Failure Or Renal Failure |
|
| A partial or total inability of kidneys to carry on excretion and salt - water regulatory functions is called as kidney or renal failure. |
| |
| Kidney failure leads to |
| |
| (a) Uremia - a condition where there is excess of urea and other nitrogenous wastes in the blood. |
| |
| (b) Salt - water imbalance |
| |
| (c) Stoppage of secretion of erythropoietin which stimulates the formation of red blood corpuscles. |
| |
| Cause |
| |
| Kidney failure is caused due to many reasons: |
| |
| (a) Tubular injury |
| |
| (b) Infection |
| |
| (c) Bacterial toxins |
| |
| (d) Inflammation of glomeruli |
| |
| (e) Arterial or venous obstruction |
| |
| (f) Fluid and electrolyte depletion |
| |
| (g) Intrarenal precipitation of calcium and urates. |
| |
| (h) Drug reaction |
| |
| (i) Haemorrhage |
| |
| Prevention |
| |
| Proper maintenance of the normal fluid balance, blood volume and blood pressure can help prevent renal failure. |
| |
| Dialysis |
| |
| Dialysis should be started as soon as possible after the renal failure has been established by diagnosis. |
