The correct answer is:
| These echoes come from a treatment was clearly successful, as determined by the clinician who could clearly make out a single stone in the X-ray at the start of the procedure, and multiple stone fragments in the X-ray at the end of the procedure (B). | |
| These echoes come from a treatment whose outcome was declared to be unsuccessful (the X-ray image of the stone at the end of the treatment was very similar to the image at the start, implying that probably only minor fragmentation occurred) (A). | |
| These echoes come from a treatment whose outcome was declared to be partially successful (the X-ray image of the stone at the end of the treatment looked somewhat smaller and less dark, implying a change in density) (C) |
If you wish, please email the results of your test (subject: litho test) to leightonlitho@isvr.soton.ac.uk
Remember, clinicians would be able to listen to hundreds of these echoes during a single treatment, whilst you have to make a judgment from just a single pair.
We asked three clinicians to undertake this test, with proper subjective testing protocols (including randomization of presentation of signals). All three successfully identified the features which would distinguish a successful treatment from an unsuccessful one.
