膀胱癌是泌尿生殖系统最常见的恶性肿瘤,98%的膀胱癌是上皮源性肿瘤,大多数是移行细胞癌[1]。膀胱癌术后复发率较高,特别是在行保留膀胱的各种术式后。临床治疗中为提高治疗效果采取多种术后治疗方案,包括膀胱腔内化疗、免疫治疗、全身化疗等,但仍有较高的复发率。膀胱腔内介入治疗也有应用,但因操作较复杂未广泛开展。本实验研究经球囊途径置入核素行膀胱腔内照射,并初步观察在该方式下碘131(131I)膀胱内照射对膀
Bladder cancer is the most common malignant tumor of the genitourinary system. 98% of bladder cancers are epithelial tumors, most of which are transitional cell carcinomas [1]. Postoperative bladder cancer recurrence rate is high, especially in the bladder after various surgical procedures. Clinical treatment to improve the treatment effect to take a variety of postoperative treatment programs, including intravesical chemotherapy, immunotherapy, systemic chemotherapy, but there is still a high recurrence rate. Interventional treatment of the bladder cavity is also used, but it is not widely carried out due to the complicated operation. In this study, we investigated the intracavitary irradiation of radionuclides implanted by the balloon route and preliminary observation of the effects of iodine 131 (131I) intravesical irradiation on the bladder
