一、前言外科的睾丸切除术对晚期前列腺癌的患者是一种重要治疗手段。美国每年有数千人行此手术。虽然完全好的睾丸切除术(包括睾丸被膜、附件、远则精索)是一种常见手术,但被膜下睾丸切除术较其他方法有更多的优点。就病人来说,进行睾丸切除较阴囊睾丸切除更易接受。另外,被膜下睾丸切除术的并发症较少,切除的组织也较少,精索的残端部分没有痛感。用二氧化碳激光进行被膜下睾丸切除术,尤其对因血友病、尿毒症、抗凝药物治疗而引起出血性疾病的患者有利;可是未见文献中有此法的报道。本文报告这种方法,并对①技术的简单,②术后疼痛,肿胀、血肿形成,③术后血清睾酮水平等方面作出评价。二、资料和方法(一)病人我们用 CO_2激光对患有转移性前列腺癌的 First, the introduction of surgical orchiectomy for advanced prostate cancer patients is an important treatment. Thousands of people in the United States operate this operation every year. Although a complete examination of the orchidectomy (including the testicular capsule, attachment, far spermatic cord) is a common procedure, subchyloplastic orchiectomy has many advantages over other methods. On the patient, the testicular excision is more acceptable than the scrotal testicular excision. In addition, subchondral eyelid resection less complications, less resected tissue, sperm stump no pain. Subcapsular orchidectomy with carbon dioxide laser is particularly beneficial for patients with hemorrhagic disease due to hemophilia, uremia, anticoagulant therapy; however, no such method has been reported in the literature. This article reports this method, and ① technical simplicity, ② postoperative pain, swelling, hematoma formation, ③ postoperative serum testosterone levels and other aspects of evaluation. Second, the data and methods (A) the patient We use CO_2 laser on patients with metastatic prostate cancer
