成人尸体阴茎延长长度的测量及其静脉淋巴管的解剖学观察

Measurement of adult corpus penile prolonged length and the anatomy of penile vein and lymphatic vessel

目的 为阴茎延长术、阴茎断后再植、阴茎包皮环切、血管性阳痿等术后水肿及其治疗提供解剖学依据,并为阴茎延长手术疗效提供实验室数据。方法 在16例正常成人新鲜尸体标本上按照阴茎延长术手术方法切断阴茎浅悬韧带后测量阴茎延长的长度,并将此长度与身高进行统计学比较。另选40例新鲜阴茎标本行静脉血管铸型及淋巴管间接注射Shiff染色并结合解剖方法,观察其数量、走行、分布特点。结果 切断阴茎浅悬韧带后阴茎延长长度在2～3cm范围,与身高无明显相关。注入龟头及包皮系带的10 %印度墨汁主要通过阴茎背侧及双侧形成的2～4条阴茎浅组淋巴管主干回流,此主干与背浅静脉伴行,腹侧未见淋巴管显色。结论 在静止状态下,阴茎延长术后,阴茎的延长范围为2～3cm ;海绵体注射时尽量选择阴茎侧面近1/ 3血管稀疏区。阴茎延长术后皮下顽固水肿与背浅静脉、背侧及双侧淋巴管损伤有密切关系。

Objective To provide experimental data by exploring the anatomic structure of adult corpus penis vein and lymphatic vessel and the length after releasing penile superficial ligament. Methods The penis length of 16 adult corpuses was measured immediately after releasing the superficial ligament, and make a statistical analysis between the prolonged portion and corpus height. A total of 40 cases of fresh penis specimens were divided averagely into two groups which were performed by vascular casting, indirect-injection of lymphatic vessel, shiff stating and dissection to observe their anatomic structure. Results Prolonged penis length ranged from 2-3 cm. Indian ink of 10% injected from penile glans and frenulum of prepuce mainly flew back through dorsal and lateral lymphatic vessel, but not through ventral vessel. Conclusion Penis can be prolonged about 2-3 cm by releasing the superficial ligament out of erectile condition. One-third proximal lateral area is advised for injection of bulbocavernosus body because blood vessels are less here. Obstinate edema after penis lengthening surgery has a close relation with the damnification of dorsal superficial vein and dorsal and lateral lymphatic vessel of penis.
