Spinal cord injury (SCI) severely affects motor, sensory, reflex, and other functions, impacting 250,000 to 500,000 individuals globally each year. Bladder voiding dysfunction, a prevalent and serious complication of SCI, results in significant morbidity and reduced quality of life. This study examines the impact of nurse-led clean intermittent catheterization combined with synchronous health education for family members on improving compliance in patients with SCI and bladder voiding dysfunction.
