This retrospective study was conducted in 521 men with micturition complaints to determine the relationship between prostate size and bladder-outlet obstruction. Analysis showed a statistically significant correlation between bladder-outlet obstruction and prostate size. Urodynamic bladder-outlet obstruction was confirmed in 90% of the patients with a prostate size of more than 80 cm3. In 32% of the patients with a prostate smaller than 40 cm3, no urodynamic evidence of bladder-outlet obstruction was found. There was no correlation between symptom scores (Madsen and I-PSS) and the grade of bladder-outlet obstruction or prostate size. We conclude that precise determination of the prostate size and urodynamics investigations are important (complementary) parameters in the assessment of elderly men with micturition complaints.
