Interstitial Cystitis (IC)-Like Findings With Hydrodistension

Interstitial Cystitis Clinical Trial

Official title: Correlation Between Urinary Symptoms and Interstitial Cystitis (IC)-Like Findings on Cystoscopy With Hydrodistension

Status Terminated

Clinical Trial Summary

Patients who are already scheduled to have a gynecologic, urologic or uro-gynecologic procedure involving cystoscopy (a lighted scope is used to look inside the bladder) under anesthesia will be approached to participate in the study. Once prospective study subjects are consented, they will be requested to complete the study questionnaires.

At the time of the procedure, during the cystoscopy, patients will undergo hydrodistension (stretching the bladder with fluid). Photographic images of the bladder will be collected, to be later analyzed by examiners. Patients who have positive findings for interstitial cystitis during cystoscopy with hydrodistension, will be notified of the findings after the procedure.

They will be asked to fill out an additional, previously completed questionnaire at the time of a follow-up visit, during a phone interview or responding to the questionnaire via a secure web site. These patients will be treated for interstitial cystitis by their primary providers as clinically indicated.

Clinical Trial Description

Patients who are already scheduled to have a gynecologic, urologic or uro-gynecologic procedure involving cystoscopy will be approached to participate in the study. They will be approached either at the time of an office visit or on the day of the scheduled procedure in the preoperative area.

Study-Related Once consented, they will be requested to fill out the study questionnaires. IC Problem Index/IC symptom Index, Pelvic Pain and Urgency/Frequency Patient Symptom Scale(PUF), IBS (Irritable Bowel Syndrome) questionnaire, Functional Esophageal Disorder Questionnaire, and Painful Bladder questionnaire. Completion of these questionnaires should take approximately 15 minutes.

All patients will undergo cystoscopy with hydrodistension as part of the study protocol. Cystoscopy with hydrodistension is used as a diagnostics/evaluative test.

Cystoscopy-Standard of care The bladder will be be emptied prior to cystoscopy. Cystoscopy will be performed with a 5 mm 30o or 70o cystoscope. The angle of view through the scope (or what the physician sees) is described as 30 degrees or 70 degrees. Sterile saline or water will be infused under direct visualization. Fluid bag will be held at 80 cm above the patient. After 200 cc's of filling the infusion will be stopped. This is the standard procedure for cystoscopy. A resurvey of the bladder will be performed. A minimum of two pictures will be taken - one of the back wall and one of the dome of the bladder. Any abnormal findings will be recorded as well.

Hydrodistension- standard of care or study related. The bladder will be filled by gravity (no pressure) the fluid bag is held 80-100cm above the bed level and the bladder is filled by gravity. Fluid will stop when the bladder reaches capacity or the physician will stop the flow when 700cc is reached. Once the bladder is filled, it is then partially emptied. This procedure should take no more than 60 seconds. The bladder is left partially filled so the physician can take a final look (resurvey) at the bladder before the procedure is completed and the scope withdrawn. This is the standard procedure for hydrodistension. At least five pictures will be taken: trigon, left and right bladder wall, posterior wall of the bladder, and dome of the bladder. A short video clip (approximately 10-15 seconds long) will be taken as well for documentation. Again, any abnormal findings will be documented.

Image review-study related Cystoscopic images will be de-identified and pooled. Batches of 25 sets of images will be evaluated by a panel of urogynecologists. Each reviewer will evaluate each set of images, ranking them as: positive, equivocal or negative for interstitial cystitis findings. A minimum of 10 glomerulations per quadrant in 3 out of 4 quadrants, or any Hunner ulcers will be required for positive diagnosis. Glomerulations will be graded by distribution and number. Additional findings will be recorded: trabeculations, metaplasia, masses, stones, etc. In cases of equivocal findings, the panel can review video clip that may contain additional visual information.

Study related Patients who have positive findings for interstitial cystitis during cystoscopy with hydrodistension, will be notified of the findings after the procedure. At their 4 week and 6 month followup visits these patients will be asked to fill out the IC Problem Index/IC symptom Index questionnaire, this will be compared to the same questionnaire the patient filled out pre op. If the patient is unable to come to the office they may receive a phone call to complete the questionnaire or if they have access to e-mail they may be able to complete the questionnaire on a secure web base site (Red Cap). The follow up questionnaire will not be completed by those who are not diagnosed with interstitial cystitis and their participation in this study will end after the procedure, and they will be referred back to their primary or referring physician for follow up.

Study related The patient's medical record will also be reviewed for history and demographics.

Standard of care Patients with IC will be treated by their primary providers as clinically indicated. ;
