在老年人当中,患有前列腺增生症(以下称BPH)者较多,这是众所周知的。经临床检查,每4人中大概就有1人患有此病。通过对60岁以上男性的组织学检查和剖检,确认患有此病的约占90%。另外,该病的发病率随年龄的增长而上升。如此看来,BPH是前列腺的异常,但从生物学角度来看,则认为是伴随加龄的前列腺生理性改变。近年来,虽然掌握了有关前列腺胚胎学、雄激素代谢及增殖因素的知识,但对BPH尚有许多不明之处。作者认为BPH是由雄激素刺激所致,睾丸的存在不可缺少,那么超过生殖年龄,且雄激素也低下的老年人为什么前列腺迅速增大,其致病因素主要是性激素平衡失调,还与某些因素的影响有关。增生结节的增殖绝对不可缺少持续性的雄激素刺激。通过对许多
Among the elderly, there are many people with benign prostatic hyperplasia (hereinafter referred to as BPH), which is well-known. After clinical examination, about 1 in 4 people have this disease. By histological examination and autopsy of men over the age of 60, about 90% of patients with this disease are confirmed. In addition, the incidence of the disease increases with age. As such, BPH is an abnormality of the prostate gland, but from a biological point of view, BPH is considered as a physiological change of the prostate accompanying aging. In recent years, although mastery of prostate embryology, androgen metabolism and proliferation of knowledge, but there are many unknown BPH. The author believes that BPH is caused by androgen stimulation, the presence of testis is indispensable, then over the reproductive age, and low levels of androgens in the elderly why the prostate increased rapidly, the main risk factors are sex hormone imbalance, but also with certain factors Impact related. Proliferation of nodular hyperplasia is absolutely indispensable androgen stimulation. Pass to many
