The morbidity of radical retropubic prostatectomy for prostate cancer has been reduced through improved understanding of the surgical anatomy of the prostate. Delineation of the anatomy of the dorsal vein complex has led to modifications in the surgical technique that have reduced blood loss and improved surgical exposure. The addition of epidural anesthesia and presurgical donation of autologous blood has limited the need for the homologous transfusion of blood to 2% of the patients and has reduced the frequency of serious perioperative complications such as pulmonary emboli to 0.3%. Delineation of the anatomy of the pelvic plexus and identification of the neurovascular bundles as the macroscopic landmark of the microscopic cavernous nerves have made it possible for the surgeon to make an informed decision at the time of surgery whether the neurovascular bundles can be preserved safely or excised widely with the specimen. In all surgical approaches to prostate cancer, the primary goal must be excision of all tumor; preservation of sexual function should be of secondary concern. These considerations were addressed in the treatment of 320 consecutive patients; 74% of the men are potent postoperatively. It was necessary to excise one neurovascular bundle widely in 49 patients; 69% are potent. In addition to improvements in postoperative sexual function, the incidence of incontinence following surgery has been reduced. The total medical expenses for patients undergoing radical prostatectomy range from $8,500 to $9,500 and are similar to those for external-beam radiotherapy.(ABSTRACT TRUNCATED AT 250 WORDS)
通过对前列腺手术解剖结构的深入了解,耻骨后根治性前列腺切除术治疗前列腺癌的发病率已有所降低。对背静脉复合体解剖结构的清晰认识,促使手术技术得以改进,减少了术中出血并改善了手术视野。硬膜外麻醉和术前自体血捐献的应用,使异体输血需求局限于2%的患者,并将严重围手术期并发症(如肺栓塞)的发生率降至0.3%。对盆腔神经丛解剖结构的清晰认识以及将神经血管束作为微观海绵体神经的宏观标志加以识别,使得外科医生在手术时能够明智地决定神经血管束是可安全保留还是应与标本一并广泛切除。在所有前列腺癌手术入路中,首要目标必须是切除所有肿瘤;性功能的保留应列为次要考虑因素。在对320例连续患者的治疗中考虑了这些因素;74%的男性术后仍有性功能。49例患者中有必要广泛切除一侧神经血管束;其中69%仍有性功能。除了术后性功能有所改善外,手术后排尿失禁的发生率也有所降低。接受根治性前列腺切除术患者的总医疗费用在8500美元至9500美元之间,与外照射放疗的费用相似。(摘要截选至250词)
