The role of scores on the path to stone-free: comparison of STONE, CROES, Guy’s, SKS and S-Resc scores after percutaneous nephrolithotomy in obese patients

Key Points

• Stone-free rates vary significantly across different scoring systems, indicating potential discrepancies in effectiveness.
• The analysis revealed that among the scores assessed, specific metrics showed increased reliability in predicting outcomes for obese patients.
• Observational analysis comparing STONE, CROES, Guy’s, SKS, and S-Resc scores after percutaneous nephrolithotomy highlights key differences.
• Understanding which scoring system best predicts stone-free status in obese patients may influence clinical management strategies.
