how to carryout aseptic bladder washout?

Answer 1

don't do that. you got a bladder infection form having sex with some drunkass and you need antibiotics, not a "bladder washout" that will introduce more bacteria into your pee-space than John Doe #67 did.

Answer 2

I would assume to do this you would need an aseptic situation- ie an aseptic room, aseptic equipment etc etc. Seeing as this is unlikely to be the situation in most people's homes, you would probably have to go to somewhere like a hospital. I would hope you wouldn't need to ask on Yahoo how to do this if this is where you worked!
