Bladder electromyography: response to electric stimulation and to terbutaline

Area of Science:

• Neuroscience
• Urology

Background:

• Traumatic spinal cord injuries often lead to paraplegia and associated bladder dysfunction.
• Managing neurogenic bladder and incontinence is a significant clinical challenge.

Purpose of the Study:

• To investigate the effects of electrical stimulation and terbutaline on bladder and external urethral sphincter function in patients with spinal cord injuries.
• To compare the efficacy of two different interventions for improving bladder control.

Main Methods:

• Nine patients with traumatic spinal cord injuries and paraplegia were studied.
• Bladder and external urethral sphincter electromyography (EMG) were performed on all patients.
• Electrical stimulation of the conus medullaris was applied to four patients, with bladder pressure recordings.
• Terbutaline was administered to five patients for asthma, with cystometry performed.

Main Results:

• Electrical stimulation resulted in increased bladder and external urethral sphincter contractility.
• Terbutaline administration led to reduced bladder electric activity and pressure at capacity.
• Terbutaline did not significantly affect external urethral sphincter function.

Conclusions:

• Electrical stimulation shows potential for enhancing bladder and sphincter function in spinal cord injury patients.
• Terbutaline's effect on the bladder warrants further investigation for potential use in managing incontinence.
• Additional research is needed to fully determine the therapeutic applications of terbutaline for bladder dysfunction.
