膀胱肿瘤的治疗方面,术前确定肿瘤是良性或恶性,以及晚期的扩展程度是很重要的。内窥镜对大多数病例无能为力,活体组织检查亦有差误。在大多数恶性肿瘤的病例,外科医师往往在手术过程的直接触诊或■诊下,才能确定手术治疗的需要或选择手术的方式。因此,谋求一种显示膀胱肿瘤是否浸润的有效方法,引起了大家的兴趣。直到最近,x 线对膀胱肿瘤的检查,甚至是体层摄影,仍然是限于形态学的描述,未能超过内窥镜检查的价值,虽然 x 线电影摄影对于膀胱动力学的研究有了很大的发展,但尚不能作为常规检查。作者为此作出了一种简易的检查方法,称为膀胱多次摄影(cystopolygraphy)。方法如下: In terms of the treatment of bladder cancer, it is important to determine before surgery whether the tumor is benign or malignant, as well as the degree of advanced expansion. Endoscopy powerless to most cases, biopsy also have some errors. In the majority of cases of malignancy, surgeons tend to be under direct palpation or diagnosis of the surgical procedure to determine the need for surgical treatment or to choose the method of surgery. Therefore, seeking an effective way to show whether the invasion of bladder cancer has aroused everyone’s interest. Until recently, x-ray examinations of bladder tumors, and even tomography, were still confined to morphological descriptions that failed to exceed the value of endoscopy, although x-ray photography has had a significant effect on bladder dynamics The development, but not yet as a routine examination. The authors made a simple test for this, called cystopolygraphy. Methods as below:
