Beware of Bipolar Transurethral Resection of Prostate in Patients with Previously Inserted Metallic Prostate Stapling Devices
Bibliographic record
Abstract
Metallic prostate stapling (e.g., UroLift) is a minimally invasive treatment option for men with bladder outlet obstruction from benign prostatic hyperplasia (BPH). While it provides rapid relief and preserves sexual function, unexpected interactions with other medical devices can compromise surgical procedures. In this letter, we highlight five cases where stapled metallic implants resulted in damage to bipolar energy device during transurethral resection of the prostate (TURP) and stimulation of obturator nerve. Laser may also reflect off metallic prostate implants which can result in laser equipment malfunction. Monopolar TURP should be considered in patients with existing metallic prostate implants who need further transurethral surgery for obstructive BPH to prevent bipolar instrument damage and obturator kick.

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.
