I had mine out on day 7, but the day after I went home I had an emergency and was back to the surgeon with my catheter blocked with massive blood clots because the hospital had not flushed them out before I was discharged per my doctors orders. I have heard in this forum of guys with the snake exhumed in less than 7 days but 7 is considered the bare minimum by most URO's. 7 days is normal so the urethra has enough time to heal where it was attached back to the bladder. Even if your URO was going on vacation there should have been another URO on call unless you live in some remote area.
