Nope. Had a good friend who was a Military Medic, telling me about doing swabs on guys that came in, 'for the itch'.After 30+ years of experience with kidney stones, I can tell you that you’d be very surprised by what can be shoved up that pipe.
Might as well have been cleaning a rifle barrel. With a steel brush, soaked in pepper sauce!
Was a strong motivator, to be wary of the too-easy!
