Problems that can caused UTI

Frequent UTIs can damage the kidney and may eventually cause 
renal failure (the kidney can no longer remove waste products 
from the blood). People with renal failure may need dialysis (a 
machine cleans their blood) or kidney transplant. 

Having a few infections is not enough to cause renal failure, but it 
is important to find our why the infection happened, because if 
there is a physical problem with the kidney, bladder or the tubes 
connecting them, treatment may prevent future infections, and 
possible renal failure.
