2 Fig. 1 Fixed 3-mm-thick prostate slices before paraffin embedding. White arrow points toward laser fiber placement; red arrows indicate grossly visible ablated area. European Urology  , DOI: ( /j.eururo ) Copyright © 2010 European Association of Urology Terms and Conditions

3 Fig. 2 Vital staining of the prostate for cytokeratin 8. (A) Whole-mount vital stain of the prostate. Arrows indicate position of the laser fibers. (B) Zoom in view using ScanScope XT slide scanning systems. No vital cells are evident between the laser fibers.

4 Fig. 3 Ablation extending to the prostatic capsule. (A) Ablation zone extends all the way to the posterior border. Arrows mark where the laser fibers were positioned. No viable cells were seen inside the 18-mm ablated area. (B) Ablation zone extending posteriorly and laterally. Arrows mark the position of the laser fibers.
