Synopsis

Neurogenic bladder occurs with impaired coordination of urinary bladder detrusor muscle contraction and internal and external urethral sphincter relaxation. This may be due to dysfunction of the central, peripheral, or autonomic nervous system involved in the control of micturition, resulting in urinary dysfunction. Neurogenic bladder describes a spectrum of phenotypes depending on the location of the neurologic injury.

Lesions in the cervicothoracic spinal cord cause an upper motor neuron (ie, spastic) bladder phenotype. Damage to sacral nerve roots leads to a lower motor neuron (ie, flaccid) phenotype. Sacral spinal cord lesions may cause mixed bladder phenotypes, with spastic and flaccid components.

Neurogenic bladder may result from multiple sclerosis, parkinsonism, spinal cord injuries, neural tube defects, cerebrovascular accidents, brain tumors, and peripheral neuropathy in the setting of type 2 diabetes mellitus and AIDS. Neurogenic bladder is often suspected clinically in patients with characteristic symptoms and a predisposing condition such as multiple sclerosis or spinal cord injury. A thorough history and urodynamic testing can confirm the diagnosis.

Symptoms are variable and include urinary incontinence, small urinary volume, difficulty initiating urinary stream, incomplete bladder emptying, changes in urinary frequency or urgency, inability to sense bladder fullness, and dysuria.
