Abstract

Reversible complication of intrathecal morphine delivered by an implanted pump is described in one patient. The patient was evaluated initially using a contrast CT of the thoracic spine as well as urodynamics studies. After decreasing the intrathecally administered morphine from 2 mg/24 hr to .5 mg/24 hr, the patient's neurogenic bladder reversed within 4 days. Implanted pumps to deliver intrathecal narcotic medications are being used currently to treat intractable pain. This is a case report of reversible urinary retention secondary to the intrathecal narcotic.
