There was an interesting conversation about this meme on that other website once. Once transporters got biofilters (TNG era, iirc), you could presumably use them to defecate and deurinate the body during transport. Not only would it prevent unsightly messes in the transporter room in cases like this, but it would probably give you a little spring in your step after a tiring away mission.

waiting for the episode where somebody suffers injuries because they've transported too much and there are biological complications because they didn't have anything passing through them
