Prostate size strongly correlates with bladder-outlet obstruction in men with micturition issues. Larger prostates increase obstruction risk, while smaller ones may show no obstruction, aiding diagnosis.

Area of Science:

  • Urology
  • Andrology
  • Geriatric Medicine

Background:

  • Micturition complaints are common in aging men.
  • Benign prostatic hyperplasia (BPH) is a frequent cause of lower urinary tract symptoms.
  • Accurate diagnosis of bladder-outlet obstruction (BOO) is crucial for effective management.

Purpose of the Study:

  • To investigate the relationship between prostate size and urodynamic bladder-outlet obstruction.
  • To assess the correlation between prostate size and micturition symptom scores.
  • To evaluate the diagnostic utility of prostate size in men with lower urinary tract symptoms.

Main Methods:

  • Retrospective analysis of 521 men with micturition complaints.
  • Correlation analysis between prostate size (cm³) and urodynamic findings.

  • Assessment of symptom scores (Madsen and I-PSS).

    • Main Results:

    • A statistically significant correlation was found between prostate size and bladder-outlet obstruction.
    • 90% of men with prostates >80 cm³ had urodynamic BOO.
    • 32% of men with prostates <40 cm³ showed no urodynamic evidence of BOO.
    • No correlation was observed between symptom scores and obstruction grade or prostate size.

    Conclusions:

    • Prostate size is a significant predictor of bladder-outlet obstruction in men with micturition complaints.
    • Urodynamic evaluation and precise prostate size determination are vital for assessing elderly men with these symptoms.
    • Symptom scores alone do not reliably indicate the severity of obstruction or prostate size.
