Which tests are commonly used to evaluate neurogenic causes of incontinence?

• A. Urodynamics to assess detrusor activity, neurologic exam for sensation/motor function, and imaging as indicated
• B. Purely blood tests
• C. Pelvic MRI only
• D. Urinalysis alone

Answer: (A)

Evaluating neurogenic incontinence requires looking at how the bladder is controlled by the nervous system, not just the symptoms. Urodynamics provides objective data on detrusor activity and bladder pressures during filling and voiding, revealing patterns like overactivity, underactivity, or detrusor-sphincter dyssynergia that point to neurologic involvement. A neurologic examination examines sensation, motor function, reflexes, and perineal innervation, which helps localize where the neural control of micturition may be disrupted and whether the issue is spinal, supraspinal, or peripheral. Imaging as indicated, typically MRI of the spine (and brain if needed), looks for structural problems such as lesions or compressive processes that could cause neurogenic symptoms. Blood tests or urinalysis alone don’t assess bladder function or neural control, and pelvic MRI by itself may miss functional issues, so combining these three elements gives a complete picture of neurogenic causes.
