The male urogenital system represents a morphologically complex region that arises from a common embryological origin. However, it is typically studied separately as the excretory system is dissected with the posterior wall of the abdomen while the reproductive features are exposed with the pelvis and perineum dissection. Additionally, the reproductive structures are typically dissected following pelvic and perineal hemisection obviating a comprehensive and holistic examination. Here, we performed a dissection of the complete male urogenital system utilizing a 70-year-old donor and room temperature silicon plastination. Identification of a direct inguinal hernia during the dissection facilitated a unique opportunity to incorporate a common abdominal wall defect into the plastination requiring a novel approach to retain patency of relevant structures. Results showed that the typical structures identified in medical gross anatomy were retained in addition to the hernia. Thus, the described approach and the resulting specimen provide valuable and versatile teaching tools for male urogenital anatomy.
男性泌尿生殖系统是一个形态复杂的区域，起源于共同的胚胎学源头。然而，通常是分别进行研究的，因为排泄系统是在腹部后壁解剖时进行剖析，而生殖特征则是在骨盆和会阴解剖时暴露出来。此外，生殖结构通常是在骨盆和会阴半切后进行解剖，从而无法进行全面和整体的检查。在此，我们利用一名70岁的捐赠者和室温硅化技术对完整的男性泌尿生殖系统进行了解剖。解剖过程中发现的直疝提供了一个独特的机会，将常见的腹壁缺损纳入硅化过程，这需要一种新颖的方法来保持相关结构的通畅。结果表明，除疝气外，医学大体解剖中所确定的典型结构得以保留。因此，所描述的方法和所得到的标本为男性泌尿生殖解剖学提供了有价值且用途广泛的教学工具。
