BACKGROUNdautonomic dysreflexia (AD) can be a life-threatening condition in patients withspinal cord injury. It is important to prevent bladder overdistension in thesepatients as it may trigger AD. Sensation-dependent bladder emptying (SDBE), asa method of bladder management, improves the quality of life and allowsphysiologic voiding. In this study, we report disruption of the SDBE habit afterbladder overdistension leading to AD with chest *** SUMMARYA 47-year-old male with a diagnosis of C4 American Spinal Cord InjuryAssociation impairment scale A had been emptying his bladder using the cleanintermittent catheterization method with an itchy sensation in the nose as asensory indication for a full bladder for 23 years, and the usual urine volume wasabout 300-400 mL. At the time of this study, the patient had delayed catheterizationfor approximately five hours. He developed severe abdominal pain andheadache and had to visit the emergency room for bladder overdistension (800mL) and a high systolic blood pressure (205 mmHg). After control of AD, ahypersensitive bladder was observed despite using anticholinergic agents. Thesensation indicating bladder fullness changed from nose itching to pain in theabdomen and precordial area. Moreover, the volume of the painful bladder fillingsensation became highly variable and was noted when the bladder urine volumeexceeded only 100 mL. The patient refused intermittent clean catheterization Finally, a cystostomy was performed, which relieved the *** using physiologic feedback, such as SDBE, for bladder management arerecommended to avoid bladder overdistension.
