What this trial studies

This clinical trial evaluates the efficacy and safety of two different doses of Bludigo™ (indigotindisulfonate Sodium Injection, USP) in determining ureteral patency during surgical procedures. It is a randomized, multicenter study involving subjects aged 18 to 85 who are scheduled for surgery requiring cystoscopy to assess ureter function. Participants will undergo screening to ensure eligibility, including medical history and baseline testing, before being randomized to receive either the drug or a saline injection. The study aims to provide insights into the optimal dosage for effective ureter assessment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 85 scheduled for surgery where ureteral patency needs to be evaluated.

Not a fit: Patients with severe chronic kidney failure or those with known hypersensitivity to Bludigo™ or similar dyes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve surgical outcomes by providing a reliable method for assessing ureteral patency.

How similar studies have performed: While similar approaches have been explored, the specific use of Bludigo™ for this purpose is novel and has not been extensively tested in prior studies.

Inclusion Criteria:

* Subjects between ≥ 18 and ≤ 85 years old
* Subjects who signed a written IRB approved, informed consent form
* Subjects scheduled for a surgical procedure in which the patency of the ureter must be assessed by cystoscopy following the procedure

Exclusion Criteria:

* Subjects with stage 4 or 5 Chronic Kidney Failure as evidenced by a GFR \<30 mL/min (calculated using the MDRD formula and standardized by using individual's body surface area) or need for dialysis in the near future, or having only 1 kidney
* Subjects with known severe hypersensitivity reactions to Bludigo™ or other dyes, including contrast dyes
* Known history of drug or alcohol abuse within 6 months prior to the time of screening visit
* Subjects, as assessed by the Investigator, with conditions/concomitant diseases precluding their safe participation in this study (e.g. major systemic diseases)
* Unable to meet specific protocol requirements (e.g., scheduled visits) or subject is uncooperative or has a condition that could lead to non-compliance with the study procedures
* Subject is the Investigator or any Sub-Investigator, research assistant, pharmacist, study coordinator, other staff or relative thereof directly involved in the conduct of the protocol
* Subjects with life expectancy \< 6 months
