The pathogenesis of benign prostatic hyperplasia (BPH) remains largely unresolved. The natural history of the disease involves two distinct phases, a pathological and a clinical one, whose pathogenesis is different. The pathologic phase is composed of two stages microscopic and macroscopic neither of which produces clinical dysuria. Nearly all men develop microscopic BPH if they live long enough but only in 50% of men microscopic BPH grows to produce a macroscopic enlargement of the gland and the evolvement happens in a period between 5 and 7 years. So different etiologies for the microscopic and macroscopic evolution of prostate can be argued. The clinical phase of BPH involves the progression of pathologic BPH to the clinical form in which the patients develop symptomatic dysuria. Again only about 50% of the men with macroscopic BPH progress to the clinical form: although macroscopic enlargement of the prostate is necessary for the development of clinical BPH it is not sufficient by itself for the progression to clinical phase and additional factors are required such as phlogosis, vascular infarct, enanchement of alpha adrenergic tone. These remarks on natural history suggest a multiple approach to BPH not addressed to treat the pathologic phase but the clinical one.
