Details and patient eligibility

About

This study is a prospective randomized controlled study. Female patients over 18 years of age, who present for treatment of pelvic organ prolapse and/or stress urinary incontinence at the Pelvic Floor Center at the Johns Hopkins Bayview Medical Center, and who consent to undergo a urogynecologic surgical procedure, will be considered for inclusion in the study. Their histories will be reviewed by their attending surgeon and if they meet inclusion and exclusion criteria, they will be recruited for participation. The primary investigator and co-investigators (attending physician, fellows) will determine patient eligibility. Regarding privacy issues, the patients will be consented for both the procedure and for the study with careful attention made to emphasize patient confidentiality. When the patient presents for surgery, they will be randomized to receive either preoperative pyridium or intraoperative fluorescein or no dye. Given the color differences between the dyes, blinding will not occur. The process for recruitment will be consistent and any deviations from the protocol will be reported to the Johns Hopkins Internal Review Board.

0 participants in 3 patient groups

No dye

No Intervention group

Description:

Participants will not receive a preoperative or intraoperative dye prior to their intraoperative concomitant cystoscopy.

Phenazopyridine

Active Comparator group

Description:

Participants will receive a single 200mg oral dose of phenazopyridine with a sip of water 30 minutes prior to their surgery which involves an intraoperative concomitant cystoscopy.

Treatment:

Drug: Phenazopyridine

Fluorescein

Active Comparator group

Description:

Participants will receive 0.25cc of 10% intravenous sodium fluorescein administered by anesthesia during their surgery, immediately prior to their intraoperative concomitant cystoscopy.

Treatment:

Drug: Fluorescein
