Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This research study is being done to learn what is the best way to perform hydrodistention. Eligible participants will be enrolled and have follow-up for three months after surgery.

The study team hypothesizes that changes in hydrodistention technique, including pressure, number of distention, and duration of distention, leads to no or minimal changes in symptom improvement for patients with Interstitial cystitis/bladder pain syndrome (IC/BPS).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Hydrodistention is a procedure designed to treat bladder and pelvic symptoms in patients with interstitial cystitis. A camera is placed inside the bladder and the bladder is filled with fluid. This procedure "resets" the signals between the bladder and brain, in order to reduce the symptoms of interstitial cystitis (such as bladder pain, urinary urgency/frequency/dysuria, incontinence, incomplete emptying, etc).

However, it is still unknown the best way to perform hydrodistention. Doctors do not know how much fluid to put in the bladder, how long to keep the fluid in the bladder, and how many times to fill the bladder.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Participants will be randomly selected to one of the arms described. There are three variables that they will be assigned: the pressure of fluid in the bladder that will be filled, the duration of time that the fluid will be held in the bladder, and the number of times the procedure is completed.
