Abstract:
PURPOSE: Histological evidence of intraprostatic inflammation is a common finding of transrectal ultrasonography (TRUS)-guided needle biopsy of the prostate in patients with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH). The aim of this study was to evaluate the relationship between intraprostatic inflammation and lower urinary tract symptoms depending on the severity of intraprostatic inflammation. MATERIALS AND METHODS: Between January 2002 and December 2006, 141 BPH patients with prostate-specific antigen (PSA) of 4.0-10.0 ng/ml underwent TRUS-guided biopsy of the prostate. The extent and aggressiveness of intraprostatic inflammation were classified into 4 grades. The relationship between the grades of extent and aggressiveness of inflammation and the International Prostate Symptom Score (IPSS) was evaluated. The IPSS was evaluated according to voiding and storage symptom scores. RESULTS: Mean storage symptom scores were increased by grade of the extent of intraprostatic inflammation (grade 0, 6.3; grade 1, 10.1; grade 2, 11.0; and grade 3, 11.3) (p<0.001). The aggressiveness of intraprostatic inflammation also showed increasing storage symptom scores with grade (grade 0, 6.3; grade 1, 10.2; grade 2, 10.9; and grade 3, 11.6) (p<0.001). Voiding symptom scores had no relationship with extent or aggressiveness of intraprostatic inflammation (p=0.942 and p=0.449, respectively). CONCLUSIONS: BPH patients with intraprostatic inflammation complained of more severe storage symptoms than did patients without inflammation. Therefore, if storage symptoms are severe, we might consider medical treatment for intraprostatic inflammation in BPH patients.
