Benign prostatic hyperplasia - Does a correlation exist between prostatic morphology and irritative symptoms?

Fifty-two consecutive patients with prostatism who underwent a prostatectomy were investigated with regard to irritative symptom score, age, prostate volume, urine culture results, degree of detrusor instability, inflammation in the prostate, and stromal, glandular or mixed prostatic histopathology. We did not find any statistical correlations between irritative symptom score and the mentioned parameters. This indicates that irritative symptoms should rather be attributed to extraprostatic factors such as e.g. bladder reaction.
