摘　　要：目的:通过比较非缺血型异常勃起和阴茎海绵体注射血管活性药物引起异常勃起的临床表现及病因,探讨在勃起过程中阴茎海绵体平滑肌如何在调节静脉血流方面起到重要作用。方法:通过观察比较16例非缺血型异常勃起和8例阴茎海绵体注射前列地尔引起长时间勃起的临床表现及转归,探讨阴茎海绵体平滑肌在阴茎勃起时对白膜下静脉丛血流的影响。结果:非缺血型异常勃起均存在阴茎海绵体血流量增加,长时间维持勃起,但无一例转变为缺血性异常勃起。阴茎海绵体注射血管活性药物引起的异常勃起如无及时治疗将发生缺血性异常勃起。结论:非缺血型异常勃起与阴茎海绵体注射血管活性药物引起的异常勃起由于阴茎海绵体平滑肌功能状态的不同产生了完全不同的转归。阴茎海绵体平滑肌功能在阴茎勃起过程中的静脉血流闭塞和恢复起了重要作用。Objectives： To investigate the significance of the function of smooth muscle of corpus caverno- sum in controlling vein blood flow in erection process by comparing the clinical manifestation and causative agent of priapism caused by non - ischemia and corpus cavernosum vasoactive drug injection. Methods ： Through observing and comparing clinical manifestation and outcome of sixteen cases of non - ischemic priapism and eight cases of long -time erection caused by injecting prostaglandin E1 in corpus cavernosum, influence of corpus cavernosum smooth muscle on cluster blood flow under albuginea during the process of penis erection was investigated. Results： All ca- ses of non - ischemic priapism had the feature of increased flow of blood in corpus cavernosum and maintained long - time erection, but none of them turned to be ischemic priapism. Besides, if priapism caused by injecting vasoac- tire drug in corpus cavernosum was not cured timely, there would be ischemic priapism. Conclusions ： Non - ische- mic priapism is different from the priapism caused by intra - cavernous drug injection, due to the function of corpus cavernosum smooth muscle, which plays a significant role in blood flow occlusion and recovery of vein during the process of erection.
