Why during prerenal renal flop blood pressure drops while during inrarenal renal disappointment it go up?
Answers:
Pre-renal renal failure is primarily due to a drop contained by the circulating blood volume. This may occur due to dehydration as a consequence of diarrhoea or vomiting, due to loss of blood due to bleeding, leak of fluid from the capillaries as chunk of an inflammatory response due to infection etc. Once the capacity of the body to compensate for this is overcome, at hand is a drop in blood pressure. The blood vessel in the kidneys constrict and the kidneys try to conserce as much fluid as possible. When the size of the kidneys to restrict fluid is maximal and the blood volume is still low, the kidney tubules start getting damaged due to a deficit of blood suppy and acutenecrosis results followed by complete anuria.
When renal failure is primarily due a disease of the kidney itself the kidney is not competent to regulate the fluid balance of the body usually. Salt and water retention results contained by an increase in blood pressure.
