question: My husband had a kidney stone six moths ago that was to big to pass. The stone was in the ureter on the right side. He under went 3 surgeries to get rid of it. Two laser and sonic wave ( i think ). The last surgery about a month ago being a laser and removal. After the surgery he passed several pieces of the stone and gravle like pieces. A stent was placed and removed about a week later. Scince the last surgery he has had pain on and off and has passed numerous bloodclots and what looks to be flesh. The first surgery to remove the stone was not successful. The dr. attempted three times with different scopes and could not get to the stone. The stone was pushed into the pelvis of the kidney and a second attempt was made a few weeks later with the sonic wave. The third surgery  was successful at removing the stone. Now he is having this pain and clot and flesh problem. It has been over six months and he just wants to feel better.
