Abstract
Chung and colleagues tackle the important issue of assessing bladder strength in men with voiding com-plaints after radical prostatectomy.1 We agree with the authors that bladder strength has implications for the treatment of post-prostatectomy stress incontinence, because putting a compressive sling in a man with detrusor underac-tivity could lead to urinary retention. However, we question whether the criteria they used to identify detrusor under-activity is appropriate in men after radical prostatectomy. The authors report that 41 % of the 264 men who underwent urodynamic study had detrusor underactivity, which they defined as a maximum flow rate (Qmax) less than 15 mL/sec and a detrusor pressure at maximum flow (PdetQmax) less than 20 cmH2O during voiding. These criteria are a derivation of the Bladder Contractility Index (BCI) (5*Qmax + PdetQmax, where an index less than 100 is considered weak). Both the BCI and its derivations have

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
