Cystometry and periurethral striated muscle electromyography using cold and room temperature fluid

Area of Science:

• Urology
• Neurology
• Physiology

Background:

• Neurologic lesions of the spinal cord often cause voiding abnormalities.
• Assessing detrusor reflex function is crucial for managing these patients.

Purpose of the Study:

• To compare the efficacy of bladder distention versus cold fluid stimulation in eliciting bladder contractions.
• To evaluate the reliability of the ice water test in detecting detrusor reflexes.

Main Methods:

• Patients with spinal cord lesions and voiding issues were studied.
• Bladder responses to distention and cold fluid (ice water) were compared.

Main Results:

• Bladder distention proved to be a more physiologic stimulus for bladder contraction compared to smaller volumes of cold fluid.
• The ice water test may fail to identify detrusor hyperreflexia or a present detrusor reflex.

Conclusions:

• Bladder distention is a superior method for stimulating bladder contraction in this patient group.
• The ice water test should not be the sole diagnostic tool for detrusor reflex assessment.
• For voiding cystography using iced contrast, volumes should align with standard cystometry practices.
