The association between histological prostatitis and benign prostatic hyperplasia: a single-center retrospective study

Abstract

Objective: To investigate the relationship between histological prostatitis (HP) and clinical parameters related to benign prostatic hyperplasia (BPH) in male.

Method: The clinical data of 196 BPH patients who underwent transurethral resection of the prostate were collected. According to the results of hematoxylin-eosin (H&E) staining of prostate tissue, patients were divided into two groups: BPH with HP group and BPH without HP group. Differences in acute urinary retention (AUR), prostate volume (PV), serum sex hormones, lower urinary tract symptoms (LUTS) related parameters, and systemic inflammation indicators were compared between the two groups. SPSS software v.25 was used for statistical analysis.

Results: Compared with the BPH without HP group, the BPH with HP group had greater AUR rate, PV, total IPSS, and IPSS-storage in BPH with HP group (p < 0.05). However, there were no significant differences in IPSS-voiding, post-void residual volume, maximum urinary flow rate, serum sex hormones, and systemic inflammation indicators between the two groups (p > 0.05).

Conclusions: This study suggests that patients with HP have larger PV, more severe LUTS, and a higher risk of AUR. HP is closely related to BPH and may be a key factor in the occurrence and clinical progress of BPH.
