      Objective

      To examine the safety and efficacy of Endoscopic combined intrarenal surgery (ECIRS) between the lateral decubitus (LD) and Galdakao-modified supine Valdivia (GMSV) position.

      Methods

      We retrospectively reviewed the records of 226 patients with renal stones who underwent ECIRS in the LD and GMSV positions between 2018 and 2022. Surgeries early in the study period were mainly performed in the GMSV position, while later surgeries were mainly performed in the LD position.

      Results

      The number of patients in the LD and GMSV groups was 119 and 107, respectively. The proportion of patients who had no residual stone fragments >2 mm detected on radiography the day after surgery did not significantly differ between the LD group (91.6%) and the GMSV group (97.2%). Operation time was significantly shorter in the LD group (72 vs 81 minutes; P = .02). Total fluoroscopy time was significantly shorter in the LD group (92 vs 189 seconds; P<.001). Complication rates did not significantly differ between the groups. Among the variables analyzed, the patient position was independently impact on the fluoroscopy time (OR 0.309; 95% CI, 0.167-0.571; P<.001).

      Conclusion

      ECIRS in the LD position is safe and effective and associated with shorter fluoroscopy than the GSMV position.
