Abstract Content

Introduction

Near-infrared fluorescence (NIRF) imaging navigation facilitates precise identification of the diseased site and preservation of vascularization in the ureter and surrounding organs. We report our experience using indocyanine green (ICG) and a ureteral near-infrared ray catheter (NIRC) during robot-assisted ureteral reconstruction.

Materials and Methods

We report our experience using indocyanine green (ICG) and a ureteral near-infrared ray catheter (NIRC) during robot-assisted ureteral reconstruction.

Results

Case 1: A patient with a 1.5 cm right upper ureteral stricture following ureteroscopic lithotripsy underwent robot-assisted ureteral resection and ureteroureterostomy. Placement of an NIRC just below the stricture site under fluoroscopy enabled precise intraoperative identification. Additionally, intravenous ICG injection allowed assessment of blood flow around the stricture and anastomosis site. Case 2: A patient with a left lower ureteral tumor underwent robot-assisted distal ureteral resection and ureteroneocystostomy with a Boari flap. Placement of an NIRC just below the proximal tumor site facilitated accurate tumor localization and ureteral resection. Intravenous ICG administration visualized the vascularity of both the ureter and bladder flap.

Conclusions

NIRF imaging navigation with ICG and NIRC enhances surgical precision and improves overall outcomes in robotic ureteral reconstruction.
