Abstract:
Objective To study the sensitivity and specifity for detection of bladder tumor by Narrow-band imaging flexible cystoscopy compared with WLI flexible systoscopy. Methods Between February 2009 and July 2009, NBI flexible cystoscopy and conventional WLI flexible cystoscopy with the same instrument (Olympus Exera Ⅱ endoscopy system) were both performed on 31 patients highly suspect of bladder neoplasm with same observed time and in a randomized sequenced paradigm. Every suspect mucosa lesion was biopsied in both NBI and WLI image to compare the diagnostic accuracy between them. Results Twenty-eight patients(90%) were pathologically bladder urothelial cell carcinoma (UCC). Of 28 patients 3 were Tis, 15 were Ta, 7 were T1, and 3 were T2. Twenty were low grade carcinom, 8 were high grade carcinoma and 16 had multiple tumors, 12 had a single tumor.Of 73 biopsied lesions, 61 were diagnosed UCC under WLI image with 84% sensitivity, while 80 of 91 diagnosed under NBI image with 88% sensitivity. WLI detected 23 patients with bladder UCC while NBI detected all 28 patients. NBI detected 19 additional UCC lesions in 15 of 28 patients, as compared with WLI(P＜0. 05). Conclusion NBI flexible cystoscopy can detect more bladder urothelial cell carcinoma than WLI flexible cystoscopy.
