Comparison on S.T.O.N.E. score and Guy’s stone score in evaluating the success rate and complication rate of percutaneous nephrolithotomy

Abstract:

Objective：To assess the predictive value of Guy’s score and S.T.O.N.E. score for success rate and complication rate of percutaneous nephrolithotomy（PCNL）. Methods：The present study is aretrospective study. Patients received PCNL between January 2015 and December 2017 were included in the study and were screened with included and excluded standard. GSS scores and S.T.O.N.E. score were generated based on CT image，and complication after the operation was recorded. Results：Totally 518 cases were included in the present study，and the operation success rate was 87.26%. The GSS score and S.T.O.N.E. score could both pre－dict the success rate of PCNL and residual calculi，and were associated with the length of stay，operationtime and postoperative com－plication. Conclusion：The GSS score and S.T.O.N.E. score could both predict the success rate of PCNL effectively and no significant difference was found between the two scores.
