i experienced a ruptured ureter due to a kidney stone. I currently have a 6 inch scar at the side of my tummy and a lot of pain. If the ureter is badly blocked, they usually have to cut you and mend the ureter. A stent was placed after my surgery and a catheter.
I have a friend whose ureter was kinked and surgeons had to cut it and stitch it back together. He also needed a stent and catheter afterward.
