UTI, STI/STD or something else?? Please help? - sti kidney pain

My husband is not feeling well for 3 weeks, feels hot and sweat more than usual, noticed the blood and what he believes is pus in the semen, but not when urinating, and sometimes a little spicy, but not much. No pain or burning symptoms, and only a little fatigue. Do you have a history of kidney stones, but not the pain in his back, as he usually does, what makes him think that something else.
Suggestions on what you may think that they can be considered
Real answers only please.
