Experience of narrow band imaging in the treatment of bladder cancer

The aim of study was to determine the effectiveness of narrow band imaging (NBI) in the treatment of bladder cancer.

Materials and methods. Intraoperative imaging was performed using the Image 1 SPIES (Karl Storz) platform, which provides lighting in the white-light, Spectra A and B modes. 29 patient, mean age 61,9±13,2 (M±Г) years, range 35-78 years underwent transurethral resection due to bladder cancer (Т1-2N0M0), including suspicious areas of the bladder wall that was revealed using NBI in modes Spectra A and B.

Results. Using Spectra A and B modes during transurethral bladder resection allow helped in identification of additional suspicious focci, 65% of which corresponded to tumor mucosal lesions.

Conclusions:

1. NBI provides a more accurate diagnosis of superficial bladder tumors and their recurrence with a positive predictive value of 65%.

2. Application of modes Spectra A and B of Image 1 SPIES (Karl Storz) needs the standardization of criteria and assessment of the effectiveness in randomized multicenter trials.
