Digital Nephroscopy: The Next Step
Bibliographic record
Abstract
BACKGROUND: The Hopkins rod-lens nephroscope has been the standard in percutaneous renal surgery. Despite its high resolution, it is bulky when an external camera and light source are attached. Therefore, new technology to make the scopes lighter and more ergonomic is needed. NEW TECHNOLOGY: The new Invisio Smith digital nephroscope is the first digital nephroscope from Gyrus ACMI. It was used for the first time in two patients with caliceal stones. The tip houses dual LED-driven light carriers and a 1-mm digital camera, which obviate the need for an external light source and camera, thus eliminating the risk of drape fires and patient burns. The Smith nephroscope is much lighter (470 g vs. 939 g) and more ergonomic when compared to the standard rod-lens nephroscope. CONCLUSIONS: The Smith digital nephroscope is much lighter, more ergonomic and safer. Long term use is needed to test its durability.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
