成人阴茎局部解剖及其临床意义

Regional anatomy of the adult penis and Its clinical significance

目的:探讨成人阴茎血管神经系统走行及其横断面解剖特点,为临床阴茎再植和移植手术提供应用解剖学依据。方法:详细解剖22例成人男性尸体阴茎血管神经系统的走行及10例成人男性尸体阴茎横断面,记录阴茎血管和神经的数目、位置及其与周围重要结构的关系。结果:成人阴茎动脉主要包括阴茎背动脉、海绵体动脉和尿道球动脉;阴茎静脉系统主要包括背浅静脉、背深静脉、旋静脉、海绵体静脉和脚静脉;阴茎背神经主要平行分布于阴茎背侧,平均数目为(3.5±1.6)支。阴茎根部横断面解剖显示阴茎Buck's筋膜与海绵体白膜之间存在多条静脉,阴茎背侧左右侧对称分布阴茎背深静脉、背动脉和伴行神经,两侧阴茎海绵体内呈血窦状,白膜下可见静脉丛,中央可见阴茎深动脉。结论:阴茎局部解剖可进一步了解临床手术相关的重要结构,为临床阴茎离断再植以及同种异体阴茎移植打下良好的基础。

Objective：To investigate the course of normal adult penile vessels and nerves and their anatomical features on cross section, and to provide applied anatomy of the clinical penile replantation or transplantation. Methods：We dissected 22 cadaveric adult penile vascular nerve system and 10 cadaveric adult penile cross section. Record the number, course and distribution of penile vessels and nerves. Results： Adult penile arteries mainly include dorsal artery, corpus cavernous artery and urethral bulbar artery. Penile veins mainly include dorsal superficial veins, deep veins, circumflex veins, cavernous veins and crural veins. Penile dorsal nerves mainly distribute the dorsum of penis at equal pace and its average number was （3.5±1.6）. The anatomy on cross section of radix penis showed that there are a lot of vessels distributed between Bucks fascia and tunica albuginea corporis spongiost. Penile deep dorsal veins, arteries and nerves are symmetric distributed on the dorsum of the penis. Each side of spongy body present blood sinusoid and deep artery was inside it. Conclusions：Dissecting the regional anatomy of penis can help us know the important structure further which was closely connected with the clinical surgery, which will make a satisfactory foundation on clinical penile replantation and penile transplantation.
