Rezūm is a minimally invasive procedure to ablate benign prostatic tissue. Herein, we report the prospective, multi-center results of the largest cohort of prostates ≥80 mL treated with Rezūm. METHODS: A prospective registry was established for Rezūm therapy in Canada (2019) at two high-volume centers. We reviewed data for patients followed between April 2019 and June 2023. All patients had baseline medical and BPH history documented along with uroflowmetry (Qmax and PVR), and validated questionnaires (IPSS, IPSS QoL, BPHII, IIEF-15, MSHQ-EjD function and bother). RESULTS: 175 patients (mean age 68.8±8.3 years) with prostate size ≥80 ml were treated with Rezūm. The median prostate volume was 105 ml (range 80-271 ml), 11.4% had prostate volume >150 ml and 79.4% had a median lobe. A prior history of urinary retention was documented in 54 patients. The procedure involved an average of 14±3.6 injections and median duration was 5 minutes (ranging from 2 to 13 minutes). Post-procedure catheterization was required for a mean duration of 14.3±7.7 days. IPSS reduced from a baseline score of 21.8 to 9.1, 9.3, 10.1 at 3, 12 and 24 months respectively. IPSS QoL score improved from a baseline of 4.5 to 1.5 at 12 months and 1.4 at 24 months. Qmax improved from a mean baseline of 7.8 ml/s up to 19.7 ml/s at 12 months. BPHII improved from a baseline of 7.3 to 2.3 at 12 months and further improving to 1.8 at 24 months. IIEF and MSHQ showed no significant change from baseline to 24 months. 11 (6.3%) patients noted retrograde/anejaculation and 8 (4.6%) patients needed retreatment at an average follow-up of 18±10.6 months. CONCLUSIONS: Rezūm therapy is a safe, effective, quick, outpatient procedure in prostate glands ≥80 ml with similar outcomes to prostates <80 mL.

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.
