group with an average drop of 1.1 g/dL per renal unit. Average pre-procedure hemoglobin was 11.87 g/dL in the multi-tract group with an average drop of 1.5 g/dL per renal unit. Average recorded estimated blood loss was 92.0 cc/renal unit in the singletract group and 131.7 cc/renal unit in the multi-tract group. Average operative time was 58.8 min/renal unit in the single-tract group and 56.2 min/renal unit in the multi-tract group. There was no difference in the number of complications between groups. Blood loss requiring transfusion was the only complication, one patient in each group received 2 units packed red blood cells. Conclusions: Multiple-tract PCNL access for large stone burden exhibits a similar safety profile to single-tract access at our institution, providing additional intra-operative approaches without an increase in periprocedural morbidity. There was a modest trend towards shorter operative times in the multi-tract cohort, despite a larger average stone burden.
