2 - Rezūm Therapy: Long-Term Outcomes at 3 Years in Patients with Enlarged Prostates
Bibliographic record
Abstract
Hypothesis / aims of study Rezūm therapy is a minimally invasive treatment for benign prostatic hyperplasia (BPH) that utilizes water vapor thermal ablation. This study evaluates the three-year outcomes of Rezūm therapy, focusing on the durability of symptom relief and improvements in lower urinary tract symptoms (LUTS). This study aimed to evaluate the long-term outcomes of Rezūm therapy by assessing the durability of symptom relief and improvements in lower urinary tract symptoms (LUTS) over a three-year follow-up period. Study design, materials and methods A prospective registry was established for Rezūm therapy at two international high-volume centers. We reviewed data for patients followed between April 2019 and October 2021. 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 In this study, we evaluated 712 patients with a one-year follow-up, analyzing LUTS and sexual function. The mean age at treatment was 67.2 years (SD 8.9) with mean baseline prostate volume was 74.1 cc (SD 34.4). Patient follow-up data for post-void residual (PVR) volumes showed a decline from a baseline mean of 134.9 ml (n=598) to 47.8 ml at 24 months (n=145), and 38.5 ml at 36 months (n=18). Qmax demonstrated improvement, increasing from a baseline mean of 8.6 ml/s (n=584) to 15 ml/s at 24 months (n=103), and 12.1 ml/s at 36 months (n=17). The IPSS showed a notable decrease, with baseline scores averaging 22 (n=627), then dropping to 9.8 at 36 months (n=64). The IPSSQoL score improved from a baseline mean of 4.5 (n=627) to 1.9 at 36 months (n=64). BPHII improved from a baseline mean of 7.7 (n=489) to 2.9 at 12 months (n=210), 2.2 at 24 months (n=105), and 2.7 at 36 months (n=51). No statistically significant differences were observed in the IIEF or the MSHQ-EjD function and bother domains. Interpretation of results The Rezūm procedure resulted in significant improvements with sustained benefits over three years. Concluding message These findings underscore the treatment's effectiveness in enhancing patient well-being while maintaining stable sexual function.

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.
