膀胱癌是泌尿系统最常见的恶性肿瘤、具有多发、易复发、复发后恶性程度提高等特点。虽然膀胱镜检查仍然是早期诊断膀胱癌的主要手段,但是目前常用的普通膀胱镜不易发现膀胱黏膜的细微病变,可能导致漏诊或手术治疗不彻底。窄波成像(NBI)是21世纪初新研发的全新诊断技术,其能够显著增强膀胱镜检查的对比度和清晰度,能够更加清楚地显示黏膜表层的毛细血管和腺管开口,不仅可以提高膀胱癌的早期诊断水平,还可以有效地为经尿道膀胱肿瘤电切术手术提供指导。尽管对NBI应用的远期效果以及能否减少膀胱癌患者术后膀胱灌注和膀胱镜检查的次数还有待进一步研究和观察,但是NBI技术所具有的独特优势为膀胱癌的早期诊断和治疗提供了新的契机。
Bladder cancer is the most common malignant tumor of the urinary system, with multiple, easy to relapse, malignant degree after recurrence and so on. Although cystoscopy is still the primary means of early diagnosis of bladder cancer, the common cystoscopy is not easy to find small lesions of the bladder mucosa, which may lead to incomplete diagnosis or surgical treatment. Narrow wave imaging (NBI) is a new diagnostic technique newly developed in the beginning of the 21st century. It can significantly enhance the contrast and clarity of cystoscopy. It can clearly show the opening of capillaries and ducts in the mucosal surface, and can not only improve bladder cancer Of the early diagnosis, but also can effectively provide guidance for transurethral resection of bladder tumor surgery. Although the long-term effect of NBI application and whether to reduce the number of postoperative bladder perfusion and cystoscopy in patients with bladder cancer remains to be further studied and observed, the unique advantages of NBI technology provide early diagnosis and treatment of bladder cancer New opportunity.
