664 Neurogenic Bladder

Many complications can result in patients with neurogenic bladder, such as bladder infection and skin breakdown related to incontinence. In addition, urolithiasis (stones in the urinary tract) is a common complication. Patients with spinal lesions above T7 are also at risk for autonomic dysreflexia, a life-threatening complication. Autonomic reflexia results from the body's abnormal response to stimuli such as a full bladder or a distended colon. It results in severely elevated blood pressure, flushing, diaphoresis, decreased pulse, and a pounding headache. Chronic renal failure (CRF) can also result from chronic overfilling of the bladder, causing backup pressures throughout the renal system.
