前列腺癌有两种主要疗法:根治性前列腺切除和放疗。但两者均伴有大量并发症。前列腺冷冻手术问世以来技术不断改进,以直肠超声监测经皮置放冷冻探头已使并发症大大降低。现介绍一种在此基础上经改良同时置放多个探头行根治性前列腺冷冻切除(包括整个腺体、腺周组织、神经血管带和精囊近端)的新方法。 1990年6月1日至1992年5月1日,以冷冻手术共治疗55例经活检证实的各期前列腺癌病人。其中8例采用以两个探头多次冰冻的旧法治疗(1组),47例用新法(2组)。新法的具体操作如下:术前直视下于耻骨上经皮插 There are two main therapies for prostate cancer: radical prostatectomy and radiotherapy. However, both are accompanied by a large number of complications. Since the advent of cryosurgery of the prostate, techniques have been continuously improved. The use of transrectal ultrasound to monitor percutaneous placement of cryoprobes has greatly reduced complications. A new method for radical prostatectomy (including whole glands, glandular tissue, neurovascular belts, and proximal seminal vesicles) that incorporates multiple probes at the same time is presented. From June 1, 1990 to May 1, 1992, 55 cases of prostate cancer patients confirmed by biopsy were treated with cryosurgery. Eight of them used the old method of repeated freezing with two probes (group 1), and 47 cases used new methods (group 2). The specific operation of the new method is as follows:
