Effectiveness of Assessing Ureteral Patency Using Preoperative Phenazopyridine

Objectives The aims of this study were to determine the efficacy of phenazopyridine when used intraoperatively to assess ureteral patency and to investigate factors that may influence its efficacy. Methods This is a retrospective chart review performed at the Olive View–UCLA Medical Center, a Los Angeles County teaching hospital, from January 2014 through July 2016. Patients undergoing cystoscopy at the time of gynecologic surgery were identified via department case logs. All women receiving preoperative oral phenazopyridine were included. If ureteral flow was unable to be visualized with phenazopyridine alone, the medication was deemed ineffective, and sodium fluorescein was given intraoperatively. Patients were divided into a phenazopyridine effective or phenazopyridine ineffective group. Patient demographics, renal function, intraoperative fluids and urine output, estimated blood loss, timing and dose of medication administration, and complications were gathered from the chart and compared between groups using Fisher exact test, 2-sample t test, Wilcoxon test, and logistic regression for multivariable analysis.
