Final answer:
Pre-eclampsia can contribute to renal failure through mechanisms such as decreased renal blood flow and glomerular hyperfiltration.
Step-by-step explanation:
Pre-eclampsia, a condition that affects some pregnant women, can contribute to renal failure through various mechanisms. One mechanism is decreased renal blood flow. Pre-eclampsia can cause constriction of the blood vessels leading to the kidneys, reducing the amount of blood reaching the kidneys and affecting their function. Another mechanism is glomerular hyperfiltration. In pre-eclampsia, there is increased pressure in the glomerulus, leading to excessive filtration of fluid and substances, which can overload the kidneys and potentially lead to renal failure.
