Phenotyping Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) by Intravesical Contrast Enhanced - Magnetic Resonance Imaging (ICE-MRI) Bladder Permeability Assay
brief summary
Each participant will be asked to participate in this research study which distinguishes different types of Interstitial Cystitis/Bladder Pain Syndrome. Research studies include only people who wish to participate. The study team members will explain the study to each participant, and all questions about the study will be answered. Each participant will be given adequate time when deciding to participate in this study. Should the participant consent to participate, then the participant will agree to undergo have a single Magnetic Resonance Imaging (MRI) test that involves the use of radio waves and a powerful magnet which are linked to a computer that looks at the bladder. The MRI test is being performed to see if the bladder is leaky, which would suggest Interstitial Cystitis (IC). The MRI test involves placing Gadobutrol and Ferumoxytol into the bladder using a sterile catheter, a small hollow tube through which fluids pass. Preliminary data suggests that IC patients with Hunners lesions have increased Gadobutrol in the bladder wall lining.
detailed description
Visit 1 and Visit 2 (for cystoscopy if not recently performed): Potential subjects seen in the clinic as part of routine clinical care that meet inclusion and exclusion criteria will only participate in the study. Urine pregnancy test (if childbearing potential) and dip Urinalysis (UA) test (to screen for UTI) will be done on visit 1. Many of the patients screened for this study will have already had cystoscopy performed within the last 6 months as this is done to determine if patients have either Hunners lesion IC (HIC) or non-Hunners lesion IC (NHIC). Patients who have had a recent cystoscopy won't need repeat cystoscopy done during a second visit; however, if no cystoscopy has been performed within the past 6 months, cystoscopy will be performed on a second visit within 2-4 weeks of visit 1. Dip UA test (to screen for UTI) will be done on visit 2 prior to cystoscopy for those participants who have not had cystoscopy within the last 6 months. Asymptomatic control patients will need cystoscopy during visit 2 if no prior cystoscopy has been performed within the past 6 months. Thus, all participants will submit to visit 1 for screening and signing of informed consent. Visit 2 for cystoscopy will only be necessary for those patients who have not had cystoscopy performed within 6 months of completing informed consent on visit 1.
