膀胱为中空脏器,可利用这个特点进行膀胱癌的保守治疗。1961年Jones 等用噻替派注入膀胱;1972年Helmstein 用水注入膀胱,使膀胱尽量伸展,使水机械性压迫肿瘤细胞使之缺血坏死,1974年Hall 用热水灌注膀胱使癌细胞致死。上述疗法对膀胱表浅性肿瘤有效,但对浸润性肿瘤几乎无效。作者试用上述三种的综合治疗方法治疗膀胱癌。病人用持续硬膜外麻醉后,膀胱插入三腔管,用泵维持50～55℃热水在膀胱内循环;用第三孔测定膀胱内
Bladder is a hollow organ, this feature can be used for conservative treatment of bladder cancer. In 1961, Jones et al injected into the bladder with thiotepa. In 1972, Helmstein was infused into the bladder with water so as to stretch the bladder as far as possible, causing the water to mechanically pressure the tumor cells to cause necrosis and necrosis. In 1974, Hall infused the bladder with hot water to kill the cancer cells. The above treatments are effective on superficial bladder tumors but almost ineffective on invasive tumors. The authors test the above three kinds of comprehensive treatment of bladder cancer. Patients with continuous epidural anesthesia, the bladder into the three-lumen tube, with a pump to maintain hot water circulation in the bladder at 50 ~ 55 ℃; with a third hole in the bladder
