N2 - Objective To present a novel method to intraoperatively localize ureteral strictures during robot-assisted ureteroureterostomy via indocyanine green (ICG) visualization under near-infrared (NIR) light. Materials and Methods Seven patients underwent robot-assisted ureteroureterostomy for ureteral stricture by a single surgeon (D.D.E.). Intraoperative localization of ureteral stricture involved instilling ICG (25 mg in 10 mL distilled water) above and below the level of stenosis through a ureteral catheter or a percutaneous nephrostomy tube, or both. The fluorescent tracer was detected as a green color using the NIR modality on the da Vinci Si (Intuitive Surgical, Sunnyvale, CA). All patients consented to off-label use of ICG after full disclosure. Results Intraoperative ICG injection and visualization under NIR light assisted in the performance of a tension-free anastomosis in all patients. At the time of surgery, mean age was 55.7 ± 12.4 years and mean body mass index was 30.3 ± 5.8 kg/m2. Mean operative time was 171.3 ± 52.4 minutes, mean estimated blood loss was 175.0 ± 146.5 mL, and mean length of ureteral excision on pathologic analysis was 1.6 ± 0.7 cm. There were no immediate or delayed adverse effects attributable to intraureteral ICG administration. Mean hospital length of stay was 1.6 ± 1.5 days, with no postoperative complications. Mean follow-up was 5.9 ± 1.5 months, and all cases were clinically and radiographically successful at last follow-up. Conclusion Intraureteral injection of ICG with visualization under NIR light allows for real-time delineation of the ureter. Additionally, ICG administration aids in discerning healthy ureter from diseased tissue, further assisting successful robotic ureteral repair.
