Abstract

The urethra is a long muscular tubular organ that changes its internal configuration as it traverses different regions. Therefore, the pathology of each region is distinctive, and regional characteristics may influence exploration and treatment. We set out to perform detailed dissections of the male urethra and illustrate the regional specificity for each urethral segment. Therefore, we dissected the vesical cervix, showing both the normal appearance and the appearance of prostatic middle lobe adenoma. We dissected the prostatic urethra, showing the seminal colliculus, ejaculatory ducts, and prostatic utricle. We revealed the membranous urethra surrounded by the striated sphincter. We have shown the appearance of the spongy urethral bulb with its cul-de-sac appearance, the aspect of the urethral lacunae, the navicular fossa, and the external urethral meatus. We performed cross-sections through the prostatic urethra as well as dissection of the bulbourethral glands at the level of the urogenital diaphragm. All the information obtained through dissection is illustrated in high-quality graphic form and correlated with clinical applications, making this work valuable teaching material.

摘要

尿道是一个长的肌肉管状器官，当其穿过不同区域时，其内部结构会发生变化。因此，每个区域的病理学都具有独特性，区域特征可能会影响探查和治疗。我们着手对男性尿道进行详细解剖，并阐明每个尿道节段的区域特异性。因此，我们解剖了膀胱颈，展示了其正常外观以及前列腺中叶腺瘤的外观。我们解剖了前列腺尿道，展示了精阜、射精管和前列腺小囊。我们显露了被横纹括约肌包围的膜性尿道。我们展示了海绵体尿道球的外观及其盲端外观、尿道陷窝、舟状窝和尿道外口的情况。我们对前列腺尿道进行了横断面解剖，并在尿生殖膈水平解剖了尿道球腺。通过解剖获得的所有信息均以高质量图形形式呈现，并与临床应用相关联，使得这项工作成为有价值的教材。
