Effect of Monopolar Versus Bipolar Transurethral Resection of The Prostate on Erectile Function: A Randomized Controlled Trial with Phosphodiesterase-5 Inhibitors Users Subgroup Analysis.
Bibliographic record
Abstract
PURPOSE: Men with lower urinary tract symptoms (LUTS) from benign prostatic hyperplasia (BPH) often experience erectile dysfunction (ED). While transurethral resection of the prostate (TURP) can improve ED, new onset ED remains a concern. This study compares monopolar (M TURP) and bipolar (B TURP) techniques, with a subgroup analysis based on phosphodiesterase 5 inhibitor (PDE5i) use. MATERIALS AND METHODS: This randomized clinical trial included candidates for TURP aged over 50 years. Patients were divided into M TURP and B TURP groups. Erectile function was assessed using the International Index of Erectile Function 15 (IIEF 15) at baseline, six weeks, and six months post surgery. RESULTS: A total of 205 patients were analyzed (102 M TURP, 103 B TURP). Baseline characteristics, perioperative findings, and surgical complications were similar. IIEF 15 scores were comparable between groups at all time points. In the PDE5i user subgroup, M TURP showed a slight short term decline in erectile function and total scores at 6 weeks, but both groups demonstrated no significant long term changes at 6 months. CONCLUSION: No significant difference was observed between M TURP and B TURP on erectile function during medium term follow up. Patients with prior PDE5i use may experience fewer short term adverse effects on erectile function from B TURP.

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.
