Blue dye could make Children's surgery safer

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: I01. Patients from birth to \< 17 years I02. Patients whose Parents or Legal Authorized Representative (LAR) have signed a written, IRB approved, informed consent form (ICF) and applicable assent obtained. I03. Patients scheduled for urological or gynecological surgical procedures in which the patency of the ureters must be assessed by the surgeon during the surgery. Exclusion Criteria: E01. For patients ≥ 1 year of age, Stage 5 Chronic Kidney Failure (defined as an eGFR (estimated glomerular filtration rate) ≤ 15mL/min/1.73 m2). (Calculated using the revised "Bedside Schwartz" equation (Schwartz et al. 2009) ). The revised "Bedside Schwartz" for eGFR is calculated as follows. eGFR (mL/min/1.73m2) = 0.413 \* height/Scr, where height is baseline height measured in cm and Scr is baseline serum creatine measured in mg/dL; For patients less than 1 year of age, measured serum creatinine greater than 1.5-times the upper limit of normal (\>97.5 percentile) based on the reference table in Boer et al., 2010. E02. Patients weighing less than 5 kgs. E03. Patients with known severe hypersensitivity reactions to Bludigo® or other dyes including contrast agents. E04. Patients with a history of, or being evaluated or treated for, gynecologic, renal, or urogenital (ureteral or bladder) cancer. E05. Patients with known congenital cardiac conditions or who have a history of arrythmia, hypotension, hypertension, bradycardia or tachycardia. E06. Patients, as assessed by the Investigator, with other conditions / concomitant diseases precluding their safe participation in this study (e.g., major systemic diseases). E07. Unable to meet specific protocol requirements (e.g., scheduled visits), or has a condition that could lead to non-compliance with the study procedures or patient/parent/LAR uncooperative. E08. Patient is the child of Investigator or any Sub-Investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the protocol. E09. Patients with a life expectancy ≤ 6 months. E10. Requirement for concomitant treatment with renal tubule transport inhibitors or with any treatment that could potentially discolor urine (see section 6.6) E11. Patients who are pregnant or breast feeding.
