If the kidneys did not excrete excess water, a person would fill up with water in their tissues causing edema leading to congestive heart failure, congestive pulmonary failure and death. Unfortunately, this is exactly what happens in kidney failure - the kidneys don't maintain the proper water/salt balance, the body accumulates more water than it needs, the person's blood pressure goes up because the blood volume increases, the heart is damaged by the extra volume and eventually the person dies of congestive heart failure.
You would die
You'd get an increased water concentration, that will, force water into your cells and tissues, causing your body to swell.
If the fish are fresh water fish the kidneys would not work. The fish would die.

The inner fluids of fish are not as salty as the sea water therefore fish have a special gland in their gills that separates the salt from their inner fluids and excretes it back out to the sea. For fish - living in salt water is no big deal. Land creatures get rid of their excess salt by flushing it out with a bunch of extra water. There is a maximum concentration of salt to water that the kidneys are able to produce they can not make pure salt they have to have excess water to get rid of it. So what do you think would happen if you can get no excess water? What if the only water you could get was already saltier than what you have in your body? A land animal drinking sea water would only get saltier and saltier, get sick and eventually die.
Yes, the main function of the kidneys is to filter wastes and excess substances from the blood to form urine, which is then excreted from the body. Additionally, the kidneys also help regulate electrolyte balance, blood pressure, and red blood cell production.
Because you lose a significant amount of the water your kidneys would collect through your pores in the form of sweat.
Your body is primarily made up of water and without the return of it from your kidneys you would become dehydrated.
All organs use blood in some way. Your kidneys clean the blood circulating through your body of undesirables. If your kidneys stopped working, they would no longer flush undesirables from your blood to the bladder. In most all cases, a lack of kidney function will quickly elevate the toxins in your blood causing systematic shutdown of your body and will lead to death if not corrected.
If someone's kidneys were not working properly, their electrolyte balance would likely be disrupted. Kidneys play a crucial role in regulating electrolyte levels in the body by filtering and excreting excess electrolytes. Without proper kidney function, electrolytes like sodium, potassium, and calcium may become imbalanced, leading to potentially serious health complications.
loss of blood and toxic filtartion ... if not cured then death.
