近年来临床研究发现,膀胱癌的治疗采用术前放疗十膀胱切除的方案最佳,比单一治疗为优。根治性放射治疗侵润性膀胱癌( B_2期和C 期),近80%的病例子5年内失败,许多失败病例可能成为根治性膀胱切除术的适应症。作者报告1971年6月—1977年7月收治的37例(男33女4)放疗失败后实行根治性膀胱切除术的病例。33例经尿道活检证实肿瘤复发。余为放射性膀胱无机能症;放射性膀胱炎继发出血;放疗后膀胱毛细血管扩张症。根治性膀胱切除术的范围包括盆腔腹膜、膀胱、男性病人的前列腺和精囊,女性病人的前盆腔脏器。因放疗后的纤维化,难以实行盆腔血管的剥离和淋巴结清扫,已有明显淋巴结肿大或腹内转移的病例不做膀胱切除。膀胱切除选用两种术
In recent years, clinical studies have found that the treatment of bladder cancer using preoperative radiotherapy for the treatment of ten cystectomy is the best and is superior to a single treatment. Radical radiotherapy for invasive bladder cancer (stages B2 and C), with nearly 80% of cases failing within 5 years, many failed cases may be indications for radical cystectomy. The authors reported cases of radical cystectomy performed after the failure of radiotherapy in 37 cases (33 males and 4 females) admitted from June 1971 to July 1977. 33 cases of urethral biopsy confirmed tumor recurrence. Yu is a radioactive bladder energy disease; radioactive cystitis following the blood; bladder telangiectasia after radiotherapy. The range of radical cystectomy includes pelvic peritoneum, bladder, prostate and seminal vesicles of male patients, and frontal pelvic organs of female patients. Due to fibrosis after radiotherapy, it is difficult to perform pelvic vascular detachment and lymph node dissection, and cases with significant lymph node enlargement or intra-abdominal metastasis are not subjected to cystectomy. Two kinds of cystectomy
