하부 천골신경근 증상으로만 발현된 마미총 증후군 환자에서의 음경해면체근반사와 음부신경 체성감각유발전위검사

초록

Cauda equina syndrome (CES) is a neurological condition involving low back pain, radiating pain, sensory loss, motor weakness, bladder dysfunction, and bowel dysfunction. A 37-year-old man was admitted with saddle-type hypesthesia, bladder dysfunction, and bowel dysfunction, but without motor weakness and radiating pain. He was diagnosed with large sequestrated lumbar disc herniation at L5-S1 and underwent decompression surgery. The initial bulbocavernosus reflex (BCR) and pudendal nerve somatosensory evoked potential (PSEP) on postoperative day 10 showed no response. After 1 month, bladder dysfunction and bowel dysfunction improved and saddle-type hypesthesia slightly improved. We also observed improvement in the BCR and PSEP during a follow-up evaluation on postoperative day 35. These results suggest that BCR and PSEP can indicate improvements in clinical symptoms and improved prognoses for CES patients with bladder dysfunction and bowel dysfunction.
