Unfortunately, our ability to detect pT3a disease is limited. even with multiparametric magnetic resonance imaging (MRI), which is regarded as the best way to distinguish pT2 from pT3a disease resulting in uncertainty as to when nerve sparing is oncologically safe. In order to decrease this uncertainty a group from Germany have developed the NeuroSAFE technique, where after nerve sparing, a frozen section analysis of the area adjacent to the nerve spare, is performed, whilst the surgeon completes the rest of the operation, and if a PSM is detected the nerve tissue is then excised. NeuroSAFE has been shown in cohort studies to decrease PSM rate whilst promoting nerve sparing and potency. No level one data exist regarding the effectiveness of this technique.
