Approximately 3-8 million people in the United States suffer from interstitial cystitis/bladder pain syndrome (IC/BPS), a debilitating condition characterized in part by pelvic pain. In order to study nervous system contributions to the condition, a physiological model of urinary bladder pain is used in mice and rats.

Cystometry is an efficient technique to measure bladder function of small animals in vivo. The bladder is continuously infused at rates controlled through an intravesical catheter, whereas the urethra is left free for micturition. This allows for repetitive filling and emptying of the bladder, while intravesical pressure and voided volume are recorded.

FAQs
Intravesical pressure reflects pressure inside the bladder, but abdominal pressure can also influence the reading. Recording additional abdominal pressure helps distinguish pressure produced by bladder muscle activity from pressure transmitted through the abdomen. This separation makes the findings more useful when assessing involuntary contractions, impaired storage, or symptoms that may not result from bladder muscle dysfunction alone.
Pressure values become more informative when evaluated alongside bladder volume and urinary flow. A change occurring during filling may indicate a storage-related abnormality, whereas findings during urination can help identify difficulty emptying or obstruction. Considering these measurements together allows clinicians to relate pressure behavior to the phase of lower urinary tract function being examined.
Abnormal patterns may indicate that the bladder contracts when it should be storing urine, fails to generate effective pressure during emptying, or does not coordinate properly with the urethra. These distinctions help separate storage problems from voiding problems and can clarify whether symptoms reflect abnormal contractions, impaired emptying, or disrupted coordination within the lower urinary tract.
The study measures pressure as fluid enters the bladder and continues through the relevant phases of filling and urination. A catheter records intravesical pressure, while additional pressure measurements may account for abdominal effects. Clinicians then compare pressure changes with bladder volume and urinary flow to characterize storage, contraction, and emptying function.
Clinicians may use the study when symptoms suggest urinary incontinence, incomplete emptying, bladder outlet obstruction, or neurogenic bladder. Its value lies in identifying the functional pattern behind the complaint rather than relying only on symptoms. The results can show whether the main issue involves storage, involuntary activity, emptying, or coordination between the bladder and urethra.
Results can provide objective evidence about how the lower urinary tract stores and releases urine. By showing whether symptoms arise from impaired storage, abnormal bladder contractions, outlet obstruction, or poor coordination, the study helps clinicians refine diagnosis and plan treatment. It is particularly relevant when different functional causes could produce similar complaints, such as leakage or incomplete emptying.
