Examining the link between urine proteins and urinary symptoms in men with prostate enlargement
Official title: The Association of Urinary BDNF and NGF With Lower Urinary System Parameters in Patients With Bladder Outlet Obstruction Secondary to Benign Prostate Hyperplasia
Run by Marmara University · NCT06265519 · Data updated 2026-11-12
This study is testing how certain proteins in urine relate to urinary problems in older men with prostate enlargement and whether a specific surgery can help improve their symptoms.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are men aged 50-80 with bladder outlet obstruction due to benign prostatic hyperplasia.
✕Probably not a fit
Patients with known neurological diseases, diabetes, urinary tract infections, or those who have had previous prostate surgery will not benefit from this study.

What this trial studies
This study investigates the relationship between urine levels of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) with lower urinary system parameters in men suffering from benign prostatic hyperplasia (BPH) and associated bladder outlet obstruction. It aims to understand how these proteins correlate with symptoms such as increased urination frequency and difficulty in urination. The intervention involves holmium laser enucleation of the prostate to alleviate symptoms and assess changes in urinary parameters post-procedure. The study focuses on older men, as BPH is a prevalent condition in this demographic.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and management of urinary symptoms in men with BPH.
How similar studies have gone: While studies have explored urinary biomarkers in relation to BPH, this specific approach focusing on BDNF and NGF in conjunction with surgical intervention is relatively novel.
