Abstract

fetched live from OpenAlex

OBJECTIVES: To evaluate functional outcomes following Aquablation in various prostate volume and anatomical subgroups. DESIGN: A meta-analysis with individual patient data undergoing Aquablation therapy from four prospective, global, clinical studies that have been conducted with Aquablation; WATER, WATER II, FRANCAIS WATER and OPEN WATER. SETTING: Australia, Canada, Lebanon, Germany, New Zealand, UK and the USA. PARTICIPANTS: 425 men with lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) with 1-year follow-up. INTERVENTIONS: Aquablation therapy is an ultrasound guided, robotically executed waterjet ablative procedure for the prostate. MAIN OUTCOME MEASURES: The analyses focus International Prostate Symptom Score (IPSS), uroflowmetry, postoperative Incontinence Severity Index (ISI) and surgical retreatment. RESULTS: 425 men with prostates ranging in size from 20 to 150 mL underwent Aquablation therapy. The outcomes from the seven questions in the IPSS questionnaire were grouped by the following; prostates <100 mL, prostates ≥100 mL, prostate anatomy with an obstructive median lobe identifed by imaging, and prostate anatomy without an obstructive median lobe. Regardless of subgroup, all outcomes are consistent and demonstrate a significant improvement from baseline. Specifically, improvements in frequency, urgency and nocturia demonstrated bladder function improvement. Patients entering treatment with severe incontinence, ISI score >4, and regardless of prostate size, showed a reduction in incontinence during patient follow-up. Surgical retreatment due to BPH symptoms occurred in 0.7% (95% CI 0.1%-2.0%). CONCLUSIONS: Across a variety of prostate anatomies, Aquablation therapy showed remarkable functional improvements following the index procedure. Additionally, men with moderate to severe LUTS/BPH and overactive bladder resulting in urge incontinence showed a reduction in incontinence symptoms postprocedure.

Not 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.
