Urinary Bladder Distention Evoked Visceromotor Responses as a Model for Bladder Pain in Mice

Overview

This study establishes a physiological model of noxious bladder pain in mice. The model aims to investigate the nervous system's contributions to interstitial cystitis/bladder pain syndrome (IC/BPS), a condition affecting millions.

Key Study Components

Area of Science

• Neuroscience
• Physiology
• Urology

Background

• Interstitial cystitis/bladder pain syndrome (IC/BPS) affects 3-8 million people in the U.S.
• IC/BPS is characterized by pelvic pain and urinary symptoms.
• Understanding the underlying mechanisms is crucial for developing treatments.
• Animal models are essential for studying pain mechanisms.

Purpose of Study

• To create a reliable model for studying bladder pain.
• To explore the role of the nervous system in IC/BPS.
• To facilitate future research on pain management strategies.

Methods Used

• Maintaining body temperature with a heating pad and radiant heater.
• Catheter insertion into the urethra of anesthetized mice.
• Making an incision to expose the left abdominal muscle.
• Using a 21 gauge needle to take a bite of muscle and inserting a bent silver wire electrode.

Main Results

• The model successfully induces bladder pain in mice.
• Physiological responses to bladder pain can be measured.
• This model can be used for further studies on IC/BPS.
• Findings may lead to better understanding and treatment options.

Conclusions

• A physiological model of bladder pain has been established.
• This model will aid in understanding the mechanisms of IC/BPS.
• Future research can build on these findings to improve patient care.
