Trial to Visualize the Ureters With Nizaracianine Triflutate in Adults Undergoing Abdominopelvic Surgery

Inclusion Criteria: * Age ≥ 18 years old * Scheduled to undergo a medically necessary abdominopelvic surgical procedure expected to last ≥ 2 hours (Phase 2) or any duration (Phase 3), during which one or more ureters should be visualized during the procedure. All abdominopelvic surgical procedures are eligible unless specifically excluded in the Exclusion Criteria. * For Phase 2, the procedure must require identification of one or both ureters using dissection, mobilization, or other surgical means. * The planned surgical procedure is open or minimally invasive surgery (MIS), including robotic. * Both ureters are expected to be present and functional. * Capable and willing to provide informed consent prior to study-specific procedures * Screening laboratory test results are within normal limits, or if any are outside of normal limits, they are considered by the site PI, and confirmed by the lead PI, to be clinically insignificant. * Negative pregnancy test in women of childbearing potential Exclusion Criteria: * Known cardiovascular or pulmonary disease, renal or liver dysfunction, immunological disease, diabetes, or active cancer that would render the study subject unfit for surgery * The planned surgical procedure is renal transplant or nephrectomy \[note: partial nephrectomy is permitted provided that estimated glomerular filtration rate (eGFR) is not expected to fall below normal age-based limits\] * Prior renal transplant * Impaired renal function defined as an estima…
