Intraoperative Cystoscopic Evaluation of Ureteral Patency: A Randomized Controlled Trial.
OBJECTIVE: To compare different modalities to aid in the evaluation of intraoperative ureteral patency on cystoscopy in the postindigo carmine era.
METHODS: In a randomized controlled trial, participants undergoing pelvic surgery were randomized into one of four groups: saline distention (control), 10% dextrose distention, oral phenazopyridine, or intravenous sodium fluorescein. Our primary outcome was visibility of the ureteral jets. Secondary outcomes included surgeon satisfaction; adverse reactions including allergies, urinary tract infections, urinary retention, cystoscopy times, and ureteral obstruction; and delayed diagnosis. Participants were followed for 6 weeks. A sample size of 176 participants was planned to demonstrate a 30% difference in the visibility scale. All analyses were performed in an intention-to-treat fashion.
RESULTS: From February 25, 2015, through August 2015, 176 participants were enrolled; 174 completed the trial, and two did not undergo intervention. Forty-four participants were included in the phenazopyridine, dextrose, saline, and sodium fluorescein groups. Sodium fluorescein and 10% dextrose resulted in significantly improved visibility and satisfaction when compared with the control group (P
CONCLUSION: Compared with the control, 10% dextrose and sodium fluorescein resulted in improved visibility and provided significantly more satisfaction in the evaluation for ureteral patency with no considerable increase in operative time or morbidity.
