## TL;DR

This paper presents a robotic-assisted surgical technique using indocyanine green to safely resect endometriosis near the ureter, improving precision in complex gynecological cases.

## Contribution

The novel use of robotic-assisted surgery with indocyanine green fluorescence for ureterolysis in parametrial endometriosis is described.

## Key findings

- Robotic-assisted surgery combined with ICG fluorescence enabled precise resection of parametrial endometriosis.
- ICG absorption in the ureteral wall allowed safe ureterolysis even without a stent.
- The patient had a short hospital stay of 48 hours post-surgery.

## Abstract

Deep infiltrating endometriosis (DIE) is a severe form of endometriosis, with endometriotic implants that can invade several anatomical structures. The urinary tract is the second most common site for deep endometriosis with ureteral endometriosis (UE) the most challenging to manage. Multidisciplinary surgery along with hormonal therapy is the corner stone for the treatment of DIE. Here we describe, with a video, a surgical technique using robotic-assisted surgery along with retrograde injection of indocyanine green (ICG) in the ureter for resection of parametrial endometriosis and ureterolysis using near-infrared fluorescence. The case was a 29-year-old nullipara with a history of severe dysmenorrhea and chronic pelvic pain. The patient was discharged after 48 hrs. The advantages of robotic surgery and the use of ICG in the ureter, in selected cases with UE, enables careful ureterolysis as ICG can even be absorbed in the ureteral mucosa/wall when no stent is left behind during surgery.
