Under the mucosa
Allow about two minutes for two rounds. This scenario is teaching content; the score supports revision and does not assess clinical competence.
The scenario
- Retrograde access for a 1 cm proximal ureteric stone.
- The wire met resistance below the stone and was advanced with some force.
What you see
- The scope reaches the wire and follows it.
- The wire runs beneath a pale, tented ridge of mucosa rather than in the lumen.
