How do patients with familial benign prostatic hyperplasia differ clinically from those with sporadic benign prostatic hyperplasia?
INTRODUCTION: The aim of this study was to compare age, prostatic volume, International Prostate Symptom Score (IPSS), maximal flow rate, serum total prostate-specific antigen (PSA), serum free PSA, free/total PSA ratio and PSA density values of familial and sporadic benign prostatic hyperplasia (BPH) patients suffering moderate or severe lower urinary tract symptoms. MATERIALS AND METHODS: Between September 1999 and August 2004, 511 patients with moderate or severe lower urinary tract symptoms (IPSS > or =8) due to BPH were included in the study. Patients with at least 2 first-degree relatives who had undergone surgery or received medication for BPH were classified as having the familial form of the disease, while the remaining patients were taken as sporadic cases. Mean age, prostatic volume, symptom score, maximal flow rate, PSA, free PSA, free/total PSA ratio and PSA density values of the familial and sporadic groups were compared using student’s t test. RESULTS: Thirty-eight patie
