始于骨盆神经丛的神经经前列腺侧后方至尿道膜部侧方,进而通过尿道膜部达阴茎海绵体。这些神经在前列腺部难以用肉眼识别,与动静脉一起形成神经血管束,因此,如以该神经血管束为指标,手术时则可保留阴茎海绵体神经。 Walsh等行前列腺癌全切术并观察了术后勃起状态,发现解剖学所见与临床结果一致。即保留神经血管束可防止全切后出现的勃起功能不全。把在前列腺全切术时保留血管束的术式称之为神经保留术。该术式首先切断膀胱部尿道,保留神经血管束并剥离前列腺。因必须先处置易出血的前列腺静脉丛,故对熟练 The nerve originating in the pelvic plexus is posterior to the posterior urethra and posterior to the urethra and then to the penis through the urethra. These nerves in the prostate gland difficult to identify with the naked eye, together with the formation of arteriovenous vascular bundles, therefore, such as the neurovascular bundle as an indicator, surgery can retain the penis nerve. Walsh et al prostatectomy and observation of postoperative erectile state, found that anatomical findings and clinical results. Retaining the neurovascular bundle prevents erectile dysfunction after a full cut. The procedure for preserving vascular bundles during total prostatectomy is called neuroreservation. The procedure first cut off the bladder urethra, retain the nerve vascular bundle and stripped the prostate. Because of the need to dispose of bleeding venous plexus, so skilled
