When passing a kidney stone, how much do you bleed?

Very variable: Can be as little as virtually none or so little that it can only be identified by microscopic examination all on extreme low side. Can be severe enough to to actually see pure blood &/or clots being passed in the urine.Mostly beeding is minor, varying from invisible to naked wye to mild pink dicoloration of urine. Amount of bleeding is no indication of size of stone or degree of blockage caused.
