经尿道二次电切治疗非肌层浸润性膀胱肿瘤的意义研究

目的探讨经尿道二次电切对治疗非肌层浸润性膀胱肿瘤的意义。方法选取首次经尿道膀胱肿瘤电切术后均诊断为非肌层浸润性尿路上皮癌患者86例,其中Ta期28例,T1期58例。术后4～6周内接受二次电切,对两次术后的肿瘤组织病理学特点进行比较。结果二次电切术后病理提示:无肿瘤者36例(41.9%);发现肿瘤残余病灶者35例(40.7%),发现肿瘤遗漏病灶者10例(11.6%);既发现残留病灶又发现遗漏病灶5例(5.8%)。首次病理Ta期患者28例,二次术后17例(60.7%)无肿瘤,6例(21.4%)病理分期与首次相同,4例(14.3%)病理分期进展至T1期,1例(3.6%)病理分期进展至T2期;首次病理T1期患者58例,二次术后19例(32.8%)无肿瘤,8例(13.8%)病理分期下降至Ta期,16例(27.6%)病理分期与首次相同,15例(25.9%)病理分期进展至T2期。Binary Logistic多元回归分析结果提示,首次电切术后肿瘤T1期、高分级、肿瘤直径>3 cm、广基形外观是影响二次术后肿瘤分期升高至T2期的独立危险因素(P<0.05)。结论经尿道膀胱肿瘤二次电切对于彻底切除肿瘤组织,明确肿瘤病理分期有相...

Significance of Second Transurethral Resection in Treating Patients with Non-Muscle Invasive Bladder Cancer

Objective To explore the significance of second transurethral resection in treating patients with newly diagnosed non-muscle invasive bladder cancer(NMIBC).Methods The research included 86 patients with stage Ta(n=28) and T1(n=58) bladder urothelial cancer.All patients underwent repeated TURBT(Re-TURBT) within 4 to 6 weeks after the initial resection.Pathologic findings of the second TURBT were compared with those of the initial one.Results Pathologic findings of Re-TURBT showed that 36(41.9%) patients were...
