经皮膀胱肿瘤电切术治疗膀胱癌15例分析

Percutaneous transvesical resection of bladder cancer (Report of 15 cases)

目的 :探讨经皮膀胱肿瘤电切术的临床应用价值。方法 :采用经皮膀胱肿瘤电切术治疗 1 5例男性表浅性膀胱肿瘤患者。结果 :均一次手术成功 ,无膀胱穿孔等并发症发生 ,术后病理检查均为表浅性膀胱癌 (移行细胞癌Ⅰ～Ⅱ级 ) ,术后电切创面及周边位置随机活检未发现肿瘤残留 ,平均随访 1 8个月 ,均无原位复发 ,异位复发 3例 ,其中 1例于术后 6个月检出 ,2例于术后 9个月检出。结论 :对于经传统尿道电切术无法完整切除的膀胱肿瘤 。

Purpose:To evaluate the efficacy of a new technique of treatment for bladder cancer involving percutaneous transvesical resection. Methods:From April 1999 to October 2001, 15 male patients with bladder cancer were selected to be treated with percutaneous transvesical resection. Results:All patients were successfully treated by this method without complications such as vesical perforation or residual tumors. Pathologic evaluation determined superficial bladder cancer in all patients. During the mean follow up period of 18 months, no evidence indicated local recurrence or iatrogenic implantation in all patients. Heterotopic recurrences (tumors recurrent in bladder sites other than the original tumor site) presented in 1 patient and 2 patients at 6 and 9 months respectively. Conclusions:This technique enables complete removal of the tumor which is located in an area that is difficult to reach with the resectoscope by transurethral approach.
