Urinary bladder

Explanation:

Urinary tract infections are mostly caused by bacteria and can affect kidneys, tubes, urinary bladder or urethra. But the urinary bladder is the most affected organ by the urinary tract infections. This is because the urinary bladder provides a site for the multiplication of organisms that have been entered in the urinary tracts. After multiplication the organisms may move to the other parts of urinary tracts but bladder remains the most affected organ and infection in it results in a feeling of burning during urination.
