Caption

Ureteral electrothermal injury, characterized by damaged collagen bundles, with swelling and fragmentation of smooth muscle fibers, is visible via histology ex vivo (left panel, 20× magnification); the dashed vertical line indicates an approximate boundary between normal (left) and injured (right) areas. Suitable for live “in-vivo” imaging, OCT captures the morphological appearance of an injured porcine ureter near the boundary of a lesion treated with high-power (36-W) electrothermal energy. LP = lamina propria, SM = smooth muscle, WT = wall thickness.
