Abstract：
BACKGROUND: Autonomic dysreflexia (AD) can be a life-threatening condition in patients with spinal cord injury. It is important to prevent bladder overdistension in these patients as it may trigger AD. Sensation-dependent bladder emptying (SDBE), as a method of bladder management, improves the quality of life and allows physiologic voiding. In this study, we report disruption of the SDBE habit after bladder overdistension leading to AD with chest pain.
METHODS: A 47-year-old male with a diagnosis of C4 American Spinal Cord Injury Association impairment scale A had been emptying his bladder using the clean intermittent catheterization method with an itchy sensation in the nose as a sensory indication for a full bladder for 23 years, and the usual urine volume was about 300-400 mL. At the time of this study, the patient had delayed catheterization for approximately five hours. He developed severe abdominal pain and headache and had to visit the emergency room for bladder overdistension (800 mL) and a high systolic blood pressure (205 mmHg). After control of AD, a hypersensitive bladder was observed despite using anticholinergic agents. The sensation indicating bladder fullness changed from nose itching to pain in the abdomen and precordial area. Moreover, the volume of the painful bladder filling sensation became highly variable and was noted when the bladder urine volume exceeded only 100 mL. The patient refused intermittent clean catheterization. Finally, a cystostomy was performed, which relieved the symptoms.
CONCLUSIONS: Patients using physiologic feedback, such as SDBE, for bladder management are recommended to avoid bladder overdistension.
