Radioisotope studies of neurogenic bladder in multiple sclerosis.

Urinary dysfunction is a frequent and often serious manifestation of multiple sclerosis. If ignored, urinary tract pathology can cause disabling symptoms and life-threatening complications. Symptomatic relief and preventative measures are available once the underlying neurogenic pathology has been identified. The conceptualization of the categories "Failure to Store," "Failure to Empty," or "Combined" provide practical diagnostic and treatment catagories. One important diagnostic test to help define treatment parameters is the radioisotope renal/residual urine study.
