When the urine does not have its characteristic clear appearance, it is often referred to as cloudy, turbid, or foamy urine. Infections anywhere in the urinary tract (UTIs), including the bladder or urethra, in both men and women, can cause blood and pus to appear in the urine, giving it a cloudy appearance.

A burning sensation with urination can be caused by infectious and noninfectious conditions, but it is most commonly due to bacterial infection of the urinary tract affecting the bladder.

When there is an infection in the urinary tract, the urine may take on a foul-smelling odor as well as appear cloudy or bloody.

When you have a UTI, it may burn when you pee. You might feel like you have to go more often. Also, the urge to pee may come on suddenly, but only a little urine comes out.
