The stone that will not let you past
Allow about two minutes for two rounds. This scenario is teaching content; the score supports revision and does not assess clinical competence.
The scenario
- A 9 mm distal ureteric stone, impacted for three weeks.
- A wire is up.
What you see
- The stone sits in an oedematous, friable segment.
- The scope reaches the stone but the ureter grips it and will not let the scope advance alongside.
