Assessing the Efficacy of Indocyanine Green for Ureter Identification During Robot-Assisted Surgery in Advanced-Stage Endometriosis

A temporary ureteral stent will be placed unilaterally (left or right) prior to robotic procedures in participants undergoing robot-assisted single-site surgery for advanced-stage endometriosis. Indocyanine green (ICG) will be administered through the stent to enable real-time fluorescence imaging for intraoperative ureter identification. The contralateral ureter will be identified using standard visualization techniques without ICG. Side allocation (ICG vs. control) will be determined by computer-generated block randomization.

Ureter identification will be performed using standard intraoperative visualization techniques without the use of indocyanine green (ICG) fluorescence imaging. This will be done on the contralateral side to the randomized ICG-assisted ureteral identification during robot-assisted single-site surgery for advanced-stage endometriosis.
