Electrode Performance Beyond the Manufacturer's Recommended Lifespan Using the Dornier MFL 5000 Lithotripter
Bibliographic record
Abstract
BACKGROUND AND PURPOSE: Electrodes used by the Dornier MFL 500 lithotripter have a specified lifespan, after which, the manufacturer recommends replacing the electrode before continuing the treatment. The aim of this study was to investigate whether electrodes continue to function effectively beyond 100% consumption by measuring the pressure output of electrodes up to 300% consumption or until electrode failure. MATERIALS AND METHODS: We assessed new, refurbished, and twice-refurbished electrodes to compare their respective performances. RESULTS: Rather than a decrease, there was a trend toward increased pressure output beyond 100% electrode consumption, with no drop in pressure prior to 300% consumption or electrode failure. All three types of electrodes functioned adequately above 100% consumption. CONCLUSION: These observations suggest that discarding the electrode before the completion of the treatment or electrode failure is not warranted. Using a single electrode rather than multiple electrodes to complete a treatment has the potential to save both time and cost.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
