RESUMEN
Objective:To analyze the clinical features related to erectile dysfunction for male patients with spinal cord injury. Methods:From December, 2019 to January, 2021, 28 male patients with spinal cord injury were detected the stiffness and periactivity index of penises during night sleep using RigiScan. The patients were grouped as presence or absence of bulbocavernous reflex, anal autonomic contraction, anal tactile sensation and anal pressure sensation, to compare the stiffness and periactivity index between the groups. Results:The stiffness and periactivity indexes were more in patients presenting bulbocavernosus reflex, anal autonomic contraction, anal tactile sensation and anal deep pressure sensation (|t| > 2.19, P < 0.05). Conclusion:Bulbocavernous reflex, anal autonomic contraction, anal tactile and anal deep pressure response may predict penile erectile function after spinal cord injury.
