[Tasa libre de litos sin complicación mayor como definición de éxito en nefrolitotomía percutánea].

Introduction: Success in percutaneous nephrolithotomy (PCNL) is defined as a stone-free status; however, major complications are highly common and have been reported as a secondary outcome.

Objective: To propose a new definition of PCNL success that comprises a stone free rate without major complications and a risk scale to predict this outcome.

Methods: Historical cohort of patients undergoing PCNL.

Rearrangement of the Guy's stone score improves prediction of stone-free rate after percutaneous nephrolithotomy.

Objective: We propose a modification of the original Guy's Stone Score (GSS) to hold on 20 % of prognostic discrimination among groups which makes this score a more reliable resource for risk assessment in patients undergoing percutaneous nephrolithotomy (PCNL).

Material And Methods: Historical cohort of 126 patients undergoing PCNL from December 2010 to November 2014 was included in the survey. Every patient was classified according to the original GSS.
