Women and children are most at risk of developing a kidney infection, as well as other urinary tract infections (UTIs) such as cystitis.
Women and children are most at risk of developing a kidney infection
In women, the urethra is closer to the anus than in men, making it easier for bacteria from the anus to enter the urethra accidentally. The female urethra is also much shorter than the male urethra (which runs through the penis). This makes it easier for bacteria to reach the bladder and move into the kidneys.
