Abstract

fetched live from OpenAlex

Objectives: To review outcomes for patients with irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD) who undergo holmium laser enucleation of prostate (HoLEP) for bothersome urinary symptoms related to benign prostatic hyperplasia (BPH). Methods: We performed a retrospective review of patients who had undergone HoLEP by a single surgeon between January 2021 and August 2023. Preoperative, intraoperative, and postoperative characteristics were compared between patients with an ICD-10 diagnosis of IBS or IBD and those without, using Chi-square and paired T -tests as appropriate. Results: Out of 918 men, 24 (2.6%) had a diagnosis of IBS, and 36 (3.9%) had a diagnosis of IBD. There were no differences in age, BMI, preoperative American Urological Association symptoms score (AUASS), preoperative Michigan Incontinence Symptom Index (MISI) score, and history of urinary retention or incontinence. The IBS + IBD cohort had smaller prostates (100.9 vs 124.2 mL, p = 0.01) and shorter procedure times (57.0 vs 66.5 min, p = 0.02) than controls. IBS patients were more likely to require anticholinergic therapy at a 3-month follow-up (31% vs 13%, p = 0.03) and had more postoperative encounters within 90 days of HoLEP (3.7 vs 2.6, p = 0.01). There were no differences regarding changes in AUASS and MISI scores, same-day trial of void and same-day discharge rates, or complication rates. Conclusion: IBS patients who underwent HoLEP had more symptomatic postoperative courses requiring higher rates of anticholinergic medication use and more provider interactions compared to men without IBS, despite similar AUASS and MISI scores. These trends were not observed in patients with IBD.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
