Comparative Analysis of RIRS Scoring System and Resorlu Unsal Stone Score (RUSS) for Predicting Stone-free Rate After Retrograde Intrarenal Surgery

Comparative Analysis of RIRS Scoring System and Resorlu Unsal Stone Score (RUSS) for Predicting Stone-Free Rate After Retrograde Intrarenal Surgery: A Prospective Cohort Study

Several studies have investigated the use of scoring systems for predicting stone-free rates after RIRS. Previous research has evaluated the RIRS Scoring System, RUSS, and other similar systems in different patient populations. This study was conducted to compare RIRS scoring system and Resorlu Unsal Stone Score (RUSS) for predicting stone free rate.
