I had the Ureteroscopy done last Thursday to remove a 6mm kidney stone. The doctor said he had to cut a hole in the bladder to take the stone out as it was too big to blast with the laser. I had the stent removed the next day as i was in too much pain. The pain/bleeding/etc subsided for me around Monday. As of yesterday [ wednesday, ] i've started passing a few blood clots. Today, i've been naseous all day. I also noticed today there was blood in my urine again. It's also been burning when I pee as of yesterday again. I did call the doctor, I have to drop in there in the morning to give them a urine sample. Should I be concerned as of yet?
