Abstract
STUDY DESIGN: Prospective, multicenter, longitudinal cohort study. OBJECTIVES: To describe female-male differences in first-line urological management during spinal cord injury (SCI) rehabilitation. SETTING: Inpatient specialized post-acute SCI rehabilitation in Switzerland. METHODS: Data on bladder storage medication (antimuscarinic and beta-3 agonist) use, suprapubic catheter placement, demographic and SCI characteristics was collected within 40 days of SCI and at rehabilitation discharge from May 2013-September 2021. Prevalence and indicators of bladder storage medication and suprapubic catheter use at discharge were investigated with sex-stratified descriptive and logistic regression analyses. RESULTS: In 748 patients (219 females, 29%), bladder storage medication use at discharge had a prevalence of 24% (95% CI: 18-29%) for females and 30% (95% CI: 26-34%) for males and was indicated by cervical AIS grade A, B, C and traumatic SCI in both sexes. Thoracic AIS grade A, B, C SCI (males), and lumbar/sacral AIS grade A, B, C SCI (females) predicted higher odds of bladder storage medication use (SCI characteristic*sex interaction, p < 0.01). Prevalence of suprapubic catheter use at discharge was 22% (95% CI: 17-28%) for females and 17% (95% CI: 14-20%) for males. Suprapubic catheter use was indicated by cervical AIS grade A, B, C SCI, and age >60 in both sexes. Females with thoracic grade A, B, C SCI tended to have higher odds of suprapubic catheter use (SCI characteristic*sex interaction, p = 0.013). CONCLUSIONS: We identified sex differences in urological management especially in persons with AIS grade C or higher sub-cervical SCI. There is scope for well-powered, female-specific research in SCI in order to understand the underlying mechanisms and support patient-tailored management.
