Abstract

Recently, several scoring systems have been proposed to predict outcomes of percutaneous nephrolithotomy, objectively and quantitatively assessing kidney calculi complexity using cross-sectional imaging. These scoring systems are promising new tools that can guide surgical decision making, predict surgical outcomes, counsel patients undergoing stone surgery, and improve standardized academic reporting in percutaneous kidney stone surgery. In this article, we review features of each of these systems, their similarities and differences, and their applicability in clinical practice and relevance in academic reporting.

The Guy’s stone score combines the number of stones, their location, and abnormal patient anatomy into a score 1–4 to estimate stone-free rates following PCNL.CrossRefPubMed

The S.T.O.N.E. score uses the stone size, tract length, obstruction, number of calyces involved, and stone density from a patient’s preoperative CT scan to calculate complexity and estimate stone-free rates following PCNL.CrossRefPubMed

Labadie, K., Okhunov, Z., Akhavein, A. et al. Evaluation and comparison of urolithiasis scoring systems in percutaneous kidney stone surgery. J Urol. 2014. In this head to head study, the relative performance of all the Guy’s, S.T.O.N.E., and CROES scores were compared and found to be equivocal in estimating stone-free rates. The Guy’s and S.T.O.N.E. scores were both predictive of blood loss and length of stay.
