The short story is that the remaining kidney is able to compensate for the lost kidney relatively rapidly. This occurs especially through hormonal changes that allow the remaining kidney to increase how much work it does.

Kidney work is measured by a term called the glomerular filtration rate (GFR), which indicates how much blood the kidney filters per unit time. After the removal of a kidney, hormonal changes occur that ultimately cause GFR in the remaining kidney to increase. Provided that the remaining kidney is healthy and that an adequate GFR is ultimately reached, individuals will survive with a single kidney with few complications.

Simple - humans only need half of one kidney to provide all the blood filtration necessary to maintain life. Having one whole kidney provides a 100% reserve in case of infection, illness or kidney disease. Having two kidneys is mostly a protective feature - if you lose one kidney, you still won't die.

What can you do if your kidney fails?

People who have kidney failure, which is when 90% or more of the kidneys do not work, must be on dialysis. When kidneys fail the body cant cleanse the body of waste. The persons blood will become toxic and the person will die without dialysis or a kidney transplant. That's just with kidney failure. Of course you can live with only one kidney. Say you only had one kidney, that one kidney would have to be over 50% damaged before a person would possibly need to be on dialysis. To simply answer your question, you could have no problems with a damaged kidney, but failed kidneys will cause death.
