[Two cases of urinary retention secondary to benign inflammatory nervous diseases]

We report two cases of acute urinary retention secondary to benign inflammatory nervous disease. Case 1 is in a 48-year-old male who was diagnosed with aseptic meningitis. Case 2 is in a 67-year-old male who was diagnosed with acute disseminated encephalomyelitis. These two cases differred in specific mechanism of the disease, but both shared symptoms of temporal voiding disturbance due to sacral radiculopathy (Elsberg syndrome). This condition is extremely rare, but should be kept in mind because delayed treatment can lead to permanent impairment.
