PurposeWe describe a case of urinary retention caused by viral sacral myeloradiculitis (Elsberg syndrome) that occurred one week after spinal anesthesia. The differential diagnosis of urinary retention after spinal anesthesia is discussed.Clinical FeaturesA 76-yr-old male patient presented for operative removal of a right testicular hydrocele under spinal anesthesia. Anesthesia and surgery were uneventful, and he was discharged on the fifth postoperative day. Two days after discharge, he developed intermittent anal pain and voiding difficulty and was readmitted to hospital on the tenth postoperative day. He subsequently developed urinary retention, incontinence of feces, and difficulty in defecation. Magnetic resonance imaging showed no epidural hematoma, abscess, or other lesions in the spinal column, cauda equina, or spinal cord. Neurological examination showed dysesthesia in the perineal region and loss of the anal reflex and bulbocavernosus response, which indicated sacral (S4-5) radiculopathy or a lesion of the conus of the spinal cord. A cerebrospinal analysis showed slight elevation of protein without pleocytosis. After neurologic consultation, herpetic sacral myeloradiculitis was suspected and intravenous acyclovir was administered along with large doses of methylprednisolone and immunoglobulin. The symptoms gradually resolved, and the difficulty in voiding resolved 19 days after initiation of the treatment. The patient was discharged 23 days after the start of the treatment without any other complications.ConclusionThis case suggests that Elsberg syndrome is important in the differential diagnosis of urinary retention after spinal anesthesia and should be discriminated from other anesthesia-related complications.
