They can do Utererscopy or URS on
stones still in the
kidney... but,
kidney stones have to be in the urine collecting part of the
kidney, the parenchyma to be removed... other than if stuck in the ureter, bladder, and the junctions from kidney to ureter and the other one. I can't remember all of this. This is an intracorporal procedure... the source to break up the stone is inside the kidney. A utererscope is used with various attachments.
