Q: Doc what causes pee urine that has blood? I have a friend…She is having itching on her vagina and as a result anytime she urinates she sees blood coming out as she urinate. What kind of infection is that?

A: This question is quite common…but comes with a couple of variations. I repeat a post ?I/ had made to a similar question in the past.

A common cause of this is Urinary Tract Infection. This is an infection that occurs anywhere in the urinary tract (Genius me, right :D) and includes infections of the kidneys, the ureters (the tubes that connect the kidneys to the bladder),  the bladder (the reservoir or store house for the urine) and the urethra (the tube that transports the urine from the bladder to the outside).

So, who is more likely to have an infection and why? Women are more likely to have infections…
