前列腺的增大达到阻塞尿道几乎是每一个老年男子的普遍现象。由于前列腺手术的改进,前列腺增生现已不是死亡的首位原因,但仍是老年人致病的主要因素。解释本病发病机制时会有三种情况。第一,前列腺的生长,无论正常与否,是以睾丸激素为媒介。第二,造成症状的病理过程实际上可能在许多年以前就开始了。第三,前列腺增生有明显的种属特异性只发生于人与犬,这种关系说明在前列腺生理学上人与犬与其他动物之间有根本的差异、对前列腺增大的发生有着决定性意义。 Swyer曾从192例尸检的前列腺中作过体积与年龄关系的研究。出生时前列腺约重1克,青春前期增 Prostatic hyperplasia to block the urethra is almost universal for every older man. Due to the improvement of prostate surgery, benign prostatic hyperplasia is not the first cause of death, but it is still the main cause of disease in the elderly. There are three situations when explaining the pathogenesis of this disease. First, the growth of the prostate, whether normal or not, is based on testosterone. Second, the pathological process that causes the symptoms may actually start many years ago. Third, there is obvious species-specific prostatic hyperplasia only occurs in humans and dogs, this relationship shows that in prostate physiology, humans and dogs and other animals have a fundamental difference between the enlarged prostate has a decisive significance. Swyer used volume-to-age studies from 192 autopsies of the prostate. Prostate about 1 gram at birth, pre-adolescent increase
