In patients with spinal cord injury, the investigators want to understand and understand the differences in AD prevalence and characteristics according to bladder injection rate, and to determine which factors have a greater influence between bladder expansion or injection rate.
It has been reported that there is a difference in the degree of AD between the bladder and urinary tract motility tests, suggesting a potential difference according to the injection rate. According to Liu et al., the authors noted that stimulation of the urethra, prostate, and internal sphincter appears to induce AD more strongly than the injection rate. In addition, the two main factors contributing to AD among urinary kinetics tests are the patient's age and bladder maximum urination pressure. Considering these factors is important in preventing AD during urinary kinetics tests. Despite these previous studies, the prevalence and severity of AD according to the injection rate of urinary kinetics tests in SCI have not been quantitatively evaluated.
