Objective: This study aimed to explore the effectiveness and safety of bilateral same-session ureteroscopy for bilateral upper urinary stones. Methods: Between January 2014 and October 2020, 88 cases in our hospital were retrospectively collected and analyzed. Patients were divided into two groups according to the stone size: <20 mm group and ≥ 20 mm groups. Based on the stone position, patients were divided into three groups: Ureter stones group, renal stones group, and ureteral + renal stones group. The operation time, initial Stone-Free Rate (SFR), final SFR, postoperative complications, total hospital stay, and postoperative hospital stay were compared. Results: The initial SFR and total SFR were 60.2% and 84.1%, respectively. The complication rate was 11.4%. The initial SFR was significantly different between the low-size group and the high-size group (71.4% vs. 32%, P<0.05). Remarkable differences in the operative time, initial SFR, and total SFR were presented among different stone location groups (P<0.05). Conclusion: BSSU may be safe and effective for the management of BUUS, especially for patients with low stone load and ureteral stones.
