Time Course of Nicotinamide Adenine Dinucleotide Diaphorase Staining after Renal Radiofrequency Ablation Influences Viability Assessment

Abstract

Staining for NADH can establish tissue non-viability after RFA, but the timing of staining after treatment must be considered when interpreting results to avoid false positive tests. Tissue that is apparently viable by NADH staining within 2.5 hours of RFA may in fact have been ablated.
