To perform a detailed anatomic study of the puboprostatic ligament and male urethral suspensory mechanism with comparisons to homologous female anatomy.
Anatomic dissections were performed on hemipelves of normal fresh male and female cadavers.
The puboprostatic ligament was not a discrete "band" of fascia that simply fixes the prostate to the public symphysis, but a pyramid-shaped structure that is part of a larger urethral suspensory mechanism that attaches the membraneous urethra to the pubic bone. As in the female, the male urethral suspensory mechanism was composed of three continuous structures: the anterior pubourethral ligament (suspensory ligament of the penis and fascial reflection of the perineal membrane), the intermediate pubourethral ligament (arcuate and transverse ligaments), and the posterior pubourethral ligament (the puboprostatic ligament). The attachments of the urethral suspensory mechanism bilaterally inserted along the lateral border of the urethra to form a sling of support from the pubic arch.
The male and female urethral suspensory mechanism are comparable. Understanding the relationship of the male urethral suspensory mechanism to the urethra, striated urethral sphincter, and dorsal vein may help in performing the apical dissection of the prostate during radical retropubic prostatectomy and in preserving urinary continence following radical pelvic surgery.
对耻骨前列腺韧带和男性尿道悬吊机制进行详细的解剖学研究，并与女性同源解剖结构进行比较。
对正常新鲜男性和女性尸体的半骨盆进行解剖。
耻骨前列腺韧带并非简单地将前列腺固定于耻骨联合的离散筋膜“带”，而是一个金字塔形结构，是将膜性尿道附着于耻骨的更大尿道悬吊机制的一部分。与女性一样，男性尿道悬吊机制由三个连续结构组成：耻骨尿道前韧带（阴茎悬韧带与会阴膜的筋膜反折）、耻骨尿道中间韧带（弓状韧带和横韧带）和耻骨尿道后韧带（耻骨前列腺韧带）。尿道悬吊机制的附着点沿尿道外侧缘双侧插入，形成一个来自耻骨弓的支撑吊带。
男性和女性尿道悬吊机制具有可比性。了解男性尿道悬吊机制与尿道、尿道横纹括约肌和背静脉的关系，可能有助于在耻骨后根治性前列腺切除术期间进行前列腺尖部解剖，并有助于在根治性盆腔手术后保持尿失禁。
