A New Nephrometry Score for Predicting Positive Surgical Margin After Laparoscopic Partial Nephrectomy.

The KESKIN ratio is a novel, easily measurable, and calculable image-based parameter that can be used to predict PSM after laparascopic PN. If externally validated in a larger patient population, the KESKIN ratio may be used in future versions of the current nephrometry scoring systems for predicting the PSM.
