阴茎异常勃起(priapism,pp)是指在无性刺激或与性欲无关的情况下,阴茎持续勃起时间超过4h以上,且不能转入疲软状态。可发生于任何年龄段,但好发于5~10岁和20~25岁[1]。PP按血流动力学分为两类:一类是高血流量型,又称动脉型或者非缺血型。另一类是低血流量型亦称静脉闭塞型或者缺血型。低血流量PP的病因常为药物性、血液病等。其实质是很多因素导致阴茎充血消退机制的衰竭[2]。藻酸双酯钠(polysacchoride sulfate,PSS)引起的PP属于低流量性的。我院2010年收治1例,结合文献分析其发病
Penile erectile dysfunction (priapism, pp) refers to asexual stimulation or sex unrelated circumstances, the penis erection time more than 4h, and can not be transferred to the weak state. May occur in any age group, but occurs in 5 to 10 years old and 20 to 25 years old [1]. PP is divided into two categories according to hemodynamics: one is high blood flow type, also known as arterial or non-ischemic. The other is low blood flow type also known as venous occlusion or ischemic. The causes of low blood flow PP often drug, blood diseases. In essence, many factors lead to the failure of the mechanism of penile congestion and regression [2]. PP caused by polysacchoride sulfate (PSS) is of low flowability. One hospital in our hospital in 2010, combined with the literature analysis of its incidence
