Reversible urinary retention secondary to excessive morphine delivered by an intrathecal morphine pump.
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.
