What is urine?

Urine is a waste product that is produced by the kidneys in their process of cleaning the blood. It is made up of water and dissolved waste products. The waste products are substances that the body does not need and that can be harmful to our organs if accumulated in the body.

The kidneys are constantly producing urine, which is sent down to the bladder. If the bladder or kidneys fail, urine builds up in the bladder. This could result in urine moving back up toward the kidneys which, in the long-term, may lead to permanent kidney damage.

It is crucial that bladder and kidney problems are treated so that urine can be passed out from the body regularly.
