经尿道微波针凝治疗膀胱癌

Transurethral microwave needle ablation of bladder cancer (report of 24 cases)

报道２４例经尿道微波针凝治疗膀胱肿瘤的临床效果。结果显示：术中及术后未发生膀胱出血及膀胱穿孔，术后肿瘤部位活检未见肿瘤残留，手术时间和治疗效果与经尿道膀胱肿瘤电切术相仿，但并发症少，住院时间缩短。术后２１例平均随坊４．１年，有２例非治疗部位发生肿瘤，而治疗部位无１例肿瘤复发。经尿道微波针凝具有简便、安全、不出血、有效及经济等优点，适用于无电切条件的医疗单位，其适应证为有蒂或直径≤２．

Transurethral microwave needle ablation of bladder caner(TUMWNABT) was carried out for 24 patients.No residual malignant tissue was found on biopsy from the irradiated sites after the procedure .There were no bleeding and vesical perforation during and after operation.The outcome of TUMWNABT group was similar to that of TURBT group and no significant difference was found between the two techniques in operative times.However, the mean hospitalization days after treatment in TUMWNABT were fewer .21 patients have been followed up for a mean of 4.1 year .In 2 cases occurrence of tumor in non irradiated sites was found ,but no recurrence of tumor in the treated areas has been observed in all the followed up patients.Being simple,minimal bleeding,safe ,effective and economical,TUMWNABT was particularly recommended for treating bladder cancer in those hospitals where transurethral resection equipment was not available.TUMWNABT was suitable for pedicled tumor or broad based tumor of ≤2.5cm in diameter.
