MP89-01 PRONE SPLIT-LEG VERSUS SUPINE PERCUTANEOUS NEPHROLITHOTOMY: OUTCOMES STRATIFIED BY GUY’S STONE SCORE Carlos Alfredo Batagello*, Cleveland, OH; Hugo Barone, Sao Paulo, Brazil; Emily Rose, Luay Alshara, Li Jianbo, Cleveland, OH; Eduardo Mazzucchi, Sao Paulo, Brazil; Manoj Monga, Cleveland, OH INTRODUCTION AND OBJECTIVES: Percutaneous nephrolithotomy (PCNL) is the gold standard procedure for treatment of large renal stones, but the optimal position based on complexity of stone burden has not been determined. Thus, our aim was to compare outcomes and complications between the prone split-leg and supine position by stratifying patients according to the Guy’s stone score (GSS). METHODS: A retrospective IRB-approved review was conducted of patients undergoing PCNL at two high-volume tertiary referral centers. At one center, patients underwent PCNL in the prone split-leg position while at the second, patients underwent PCNL in supine. Patient demographic, stone characteristics, operative details and complications were compared between both groups and according to the GSS. Statistical analysis was performed with R. RESULTS: From 830 patients, a total of 449 (54 %) underwent PCNL in prone split-leg position and 381 (46 %) in supine. The prone group had a greater mean age (56.8 vs. 47.4 y; p
