Modified three-arm port configuration for single-position, single-docking robotic nephroureterectomy: perioperative and oncological outcomes

The modified three-arm port configuration appears to be a feasible and safe approach for single-docking RANU, particularly suited to patients with smaller body frames. It demonstrates satisfactory perioperative and initial oncological outcomes in this preliminary series. Furthermore, the three-arm technique may potentially reduce operative costs. This technique may offer a practical minimally invasive option for UTUC, though validation in larger cohorts is warranted.
