Laser ablation in a tight spot near the right ureter papilla that is obstructed by the tumor. Even though the ureter could not be liberated directly due to its this walls, the mission of the procedure was to free the ureter obstruction by liberating as much tumor as possible around the papilla. Hopefully this would lead to less impingement and consequent liberation of the obstructed ureter.
