Feasibility of injected indocyanine green for ureteral ident
Ureteral identification is essential to performing safe colorectal surgery. Intra-ureteral indocyanine green (ICG) is reliable for intraoperative localization. Cystoscopy and ICG injection without stent placement are safe and fast to perform.

Case series of robotic colorectal resections where indocyanine green (ICG) injection with or without ureteral catheter placement was performed. Imaging protocol, time to ureteral identification, and factors impacting visualization are reported.

Results:
- From 2019-2020, 83 patients underwent ureteral ICG injection, 20 with catheterization and 63 with injection only.

- The main indications were diverticulitis and cancer.

- Median time to instill ICG was faster with injection alone than with catheter placement. Median time to the right ureter and left ureter visualization was not different between injection alone and catheterization.

In conclusion, ICG injection alone is faster than with indwelling catheter placement and equally reliable at intraoperative ureteral identification.
