Introduction: With increasing experience and advancing technology, endoscopy for UTUC has become more common. Endoscopic Combined Intrarenal Surgery (ECIRS) could be an option for patients with low-grade and large-volume UTUC that could be either anatomically or technically challenging to manage by retrograde flexible ureterorenoscopy.
Materials and methods: In this video, we describe, step by step, our ECIRS technique as applied to two selected clinical cases of UTUC.
Conclusion: ECIRS could represent a useful approach to UTUC in selected cases. The advantage of the "endovision" puncture and dilation technique is in the avoidance of entering the renal calyx at the level of the tumor. In addition, the combined approach, compared to the purely percutaneous approach, allows access to, and treatment of, neoplasms located in all renal calyces.
