What this trial studies

This observational study aims to investigate how bowel dysfunction impacts the recovery and outcomes of patients undergoing holmium laser enucleation of the prostate (HoLEP) for benign prostatic hyperplasia (BPH). It will assess bowel function before, during, and after the procedure using validated questionnaires, specifically the Constipation Severity Score and the Vaizey Incontinence Questionnaire. The hypothesis is that greater bowel dysfunction correlates with more postoperative symptoms and slower recovery of urinary control.

Who should consider this trial

Good fit: Ideal candidates are males aged 18-89 who are scheduled for HoLEP and can complete patient questionnaires.

Not a fit: Patients with bowel diversions, neurogenic bowel, or those undergoing concurrent surgeries may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help improve postoperative care and recovery strategies for patients undergoing prostate surgery.

How similar studies have performed: While the specific correlation between bowel dysfunction and HoLEP outcomes is less explored, similar studies have shown that pre-existing conditions can significantly affect surgical outcomes.
