USING INDOCYANINE GREEN DURING ROBOT-ASSISTED URETERAL RECONSTRUCTION

In a study published in European Urology, Ziho Lee, MD, and team pioneered the use of indocyanine green (ICG) dye that can be seen under near-infrared fluorescence to facilitate robotic-assisted ureteral reconstructions. During the procedure, the dye is injected into the diseased ureter, above and below the stricture. Near-infrared florescence is used to help identify the ureter and margins of ureteral strictures.

This study was the first to show that this technique allows for the ureter to be identified quickly and accurately. It also allows for precise localization of ureteral strictures. The results of this research were later extended to support the use of this technology for all complex ureteral reconstructive cases.

​Dr. Lee joined Northwestern Medicine in 2021 as an assistant professor of Urology. His research focuses on surgical techniques and outcomes of robot-assisted urologic reconstruction procedures and radical prostatectomy. He is the first person in the U.S. with dual fellowship training in both advanced robotic oncology and reconstruction, and he is one of the few surgeons in the country that performs complex urinary tract reconstruction robotically.
