Intraoperative cystoscopy and ureteral visualization

Over the years, I’ve been asked to inject various dyes to help light up the urine for visualization of the ureters.  Now, we’ve moved to fluorescein because it “lights up” quicker than other previous dyes.  Why are we always switching?  Drug shortages.

Dosing: 0.25 – 1.0 ml of 10% preparation of sodium fluorescein

Dose: 5 ml. bolus of 10% fluorescein intravenously.
