Brief Summary:
In this prospective, randomized trial subjects will be randomized to receive phenazopyridine or no medication prior to pelvic reconstructive procedures that use cystoscopy to confirm ureteral patency intraoperatively.

Primary Outcome Measures :
  1. Time to Visualize Ureteral Urine Flow Intraoperatively Measured by Timing in the Operating Room [ Time Frame: Day of surgery ]
    Timing was performed in the operating room. Time to visualize urine efflux was started at insertion of the cystoscope into the bladder, the time was considered complete when both ureteral orifices had displayed urine efflux.

Secondary Outcome Measures :
  1. Physician Confidence Measured by a Survey [ Time Frame: day of surgery (day 0) ]
    Surgeon response to the question: "I am confident that ureteral injury was ruled out in this patient" on a 5-point Likert scale where 1 = strongly disagree, 2 = disagree, 3 = neither agree nor disagree, 4 = agree, 5 = strongly agree

  2. Additional Interventions: Measured by Use of IV Fluids, IV Lasix, IV Methylene Blue, or Ureteral Stent Placement in OR [ Time Frame: day of surgery (day 0) ]
    this is a composite measure and will be reported as a single value for each arm as number of additional interventions

  3. Post-operative Urethral Discomfort Measured by Pain Scales [ Time Frame: post operative day 1 ]
    Measured prior to catheter removal using a 10 point visual analog pain scale: Zero represented no pain, Ten represented the most severe pain.

  4. Trial of Void Results [ Time Frame: Day of hospital discharge ]
    Number of subjects that failed a back-filled trial of void on the day of hospital discharge, up to 2 days after surgery.
