Although endoscopic ureterotomy is performed, there are still some cases that are difficult to treat. We initiated robot-assisted ureteral reconstruction as an advanced medical procedure starting in April 2022. However, the accurate identification of the stricture site has been challenging. Therefore, this study aimed to investigate the utility of a ureteral illuminating catheter (IRIS U-kit®) for robot-assisted ureteral reconstruction. METHODS: This single-center prospective study was conducted between April 2022 and October 2023 at our hospital. After obtaining informed consent, the robot-assisted ureteral reconstruction was performed. Following general anesthesia, an IRIS catheter was inserted transurethrally and placed just below the site of the stricture under fluoroscopic guidance in the lithotomy position. The catheter was illuminated with near-infrared light during robot-assisted identification and securing of the stricture (Figure 1). A double-J stent was replaced during the ureteral anastomosis. RESULTS: The average age of the patients was 56 years, with a mean BMI of 24.8 kg/m2. The median length of the ureteral stricture was 25 mm. All subjects had a previous unsuccessful laser endoureterotomy. When compared to a control group using conventional ureteral catheters, the IRIS catheter group demonstrated significant reductions in console time (144 min vs. 176 min, p=0.046) and time to securing the ureter (38 min vs. 83 min, p=0.04). In contrast, no statistical difference was seen in the anastomosis time (23 min vs. 31 min, p=0.464). The ureters were anastomosed end-to-end and sealed with six sutures using 4-0 and 5-0 PDS. A month post-surgery, all ureteral catheters were removed, with no subsequent urinary obstructions noted. CONCLUSIONS: Employing a ureteral illuminating catheter greatly enhances the precision and outcomes in robot-assisted ureteral reconstruction.
