In benign prostatic hyperplasia (BPH), prostate volume may correlate with urinary urgency, but not frequency, nocturia, or dysuria. Further research is needed to understand symptom causes in BPH patients.
Area of Science:
- Urology
- Medical Imaging
- Andrology
Background:
- Benign Prostatic Hyperplasia (BPH) is a common condition in aging men.
- Lower Urinary Tract Symptoms (LUTS) significantly impact quality of life.
- The relationship between prostate size and LUTS severity in non-obstructive BPH requires further investigation.
Purpose of the Study:
- To investigate the association between sonographically measured prostate volume and the severity of non-obstructive Lower Urinary Tract Symptoms (LUTS) in patients with Benign Prostatic Hyperplasia (BPH).
Main Methods:
- A prospective, cross-sectional study involving 60 male BPH patients.
- Patients were categorized into three groups based on prostate volume (<40 cc, 40-59 cc, ≥60 cc).
- American Urological Association symptom scores for frequency, urgency, nocturia, and dysuria were assessed and compared across groups.
Main Results:
- No significant differences in frequency, dysuria, or nocturia scores were observed between the prostate volume groups.
- A statistically significant difference was found in the urgency symptom score (p = 0.037).
- A significant positive correlation was identified between prostate volume and urinary urgency (p = 0.024, r = 0.291).
Conclusions:
- Urinary urgency is the only non-obstructive LUTS that demonstrated a potential association with prostate volume in BPH patients.
- The findings suggest that prostate size may play a role specifically in the sensation of urgency.
- Further prospective studies are recommended to fully elucidate the symptom-related causes of LUTS in BPH.
