 [ Symptoms ] in the future will there be better ways to know if medicines are safe to use during pregnancy [ Disease ] most helpful answer i never heard of a case where an std was contracted from a bottle of old urine i think you are safe even if you recently had an open wound on your hand needless to say i assume that you wash your hands thoroughly after this exposure as long as you are not showing any signs of a skin infection around this wound you are in the clear urine is typically sterile unless the person has a urinary tract infection but i still would not want to have this old pee on my hands you are wise to be concerned but it would not be likely you can catch any disease from this exposure even if you did get a minor wound infection it would not be an std
