To evaluate the anatomical relationship between the nerves and fasciae at the site of dissection in a radical retropubic prostatectomy.
Eight adult male (autopsy) en bloc specimens of bladder and rectum were examined histologically after staining with either haematoxylin and eosin or S-100 protein (as a specific nerve stain).
All specimens showed Denovilliers' fascia to have no clearly defined layers and no definable lateral edge. No distinct neurovascular bundle was seen but nerves were scattered throughout the fasciae, including medially towards the midline.
In radical retropubic prostatectomy, a piece of Denonvilliers' fascia is taken with the specimen, thus removing these nerves. The loss of these nerve fibres may explain the significant rate of erectile dysfunction after 'nerve-sparing' surgery.
评估耻骨后根治性前列腺切除术中解剖部位神经与筋膜之间的解剖关系。
八例成年男性（尸检）膀胱和直肠整块标本，用苏木精和伊红或S - 100蛋白（作为一种特异性神经染色剂）染色后进行组织学检查。
所有标本显示狄氏筋膜没有清晰界定的层次，也没有可界定的外侧边缘。未见到明显的神经血管束，但神经散布于整个筋膜，包括向内侧朝向中线处。
在耻骨后根治性前列腺切除术中，狄氏筋膜的一部分随标本一并切除，从而去除了这些神经。这些神经纤维的丧失可能解释了“保留神经”手术后勃起功能障碍的高发生率。
