NCT02182804

Brief Summary

This descriptive cross sectional study aims to directly compare the diagnostic capability of the probed-based confocal laser endomicroscopy (pCLE) and the magnifying narrow band imaging (M-NBI) in the Lugol's voiding lesions.

Limitations and Caveats

This was a pilot study and the sample size was small. We did not randomly assign the order of dNBI and pCLE. The unwashed Lugol's stain significantly influenced the observation of IPCL structure on dNBI study.
