经尿道膀胱肿瘤电切及基底部活检（附61例报告）

Biopsy of the base of superficial bladder carcinoma during transurethral resection

经尿道膀胱肿瘤电切同时行基底部活检６１例，其中７例（１１．５％）肿瘤浸润深肌层，４例再次手术时改用其他手术方法均存活２年以上。此方法对明确膀胱肿瘤分期及指导治疗，改善患者的预后均有重要意义。

In 61 cases of superficial transitional cell carcinoma of bladder, biopsy of the base of tumor was carried out during transurethral resection, Invasion of the tumor into deep musculature was thus found in 7 cases (11.5%). In 4 of them, radical cystectomy or eegmental resection was further carried out and all the four have survived more than 2 years. Biopsy of the base of superficial bladder carcinoma enables one to make more accurate staging and to plan an appropriate strategy in treatment.
