title: Pathology of benign prostatic hyperplasia.
abstract: The epidemiology of benign prostatic hyperplasia (BPH) is complex and not fully understood. The androgenic hormones testosterones and dihydrotestosterone play at least a permissive and important role. Growth factors and other hormones including estrogens may also play a role. BPH is a truely hyperplastic process resulting in growth of glandular-epithelial and stromal/muscle tissue in the prostate, leading to often measurable growth taking on different shapes and configurations which may impact symptoms and secondary outcomes. It is important to recognize that BPH is a histological conditions, which is one but not the only cause of lower urinary tract symptoms, and may or may not be associated with prostate enlargement and bladder outlet obstruction. Recognizing the different entities and determining their presence in individual patients may help with therapeutic decision making.
