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.

helloThanks for query. Your husband who has large stone probably in upper ureter The Urologist attempted endoscopic surgery of URS but could not reach out up to stone at first attempt. This is known problem when the stones are located high up in proximal ureter.Subsequently, he could break the stone at third attempt and placed a D. J stent which is a common practice for fragments of the stone to pass down without pain. Now he's getting severe pain and passing blood clots and flesh in urine. These are due to infection as a result of repeated endoscopic intervention. Please get his urine culture done and take appropriate antibiotic. All these issues will get resolved once infection is well controlled. Ensure he Chat Doctor. Do OT worry he will recover completely.
