Step 1. Transpositioning of left ureter
25 viewsInformation
Description
- A window is made under the sigmoid mesocolon to allow the transposition of the left ureter to the right side.
- For this maneuver, an endoscopic grasper is placed at the base of the right mesocolon.
- The sigmoid is then flipped over to the right side and the window is dissected from the left.
- The end of the grasper can be identified through the mesocolon by gentle agitation, from which it may be dissected to complete the window safely, avoiding vascular injury.
- Then the grasper can be advanced through the window and pull the ureter through to the right side.
