Purpose:Increased time after spinal cord injury (SCI) is associated with a migration to bladder managements with higher morbidity such as indwelling catheter (IDC). Still, it is unclear how this affects bladder-related quality of life (QoL). We hypothesized that time from injury (TFI) would be associated with changes in bladder management, symptoms and satisfaction.Materials and Methods:Cross-sectional analysis of time-related changes in patient-reported bladder management, symptoms and satisfaction using the Neurogenic Bladder Research Group SCI Registry. Outcomes included Neurogenic Bladder Symptom Score (NBSS) and bladder-related satisfaction (NBSS-satisfaction). Multivariable regression was performed to assess associations between TFI and outcomes, adjusting for participant characteristics, injury specifics, and psychosocial aspects of health-related QoL. Participants with TFI <1 year were excluded and TFI was categorized 1–5 (reference), 6–10, 11–15, 16–20 and >20 years.Results:Of 1,420 participants mean age at injury was 29.7 years (SD 13.4) and mean TFI was 15.2 years (SD 11.6). Participants grouped by TFI included 298 (21%) 1–5, 340 (24%) 6–10, 198 (14%) 11–15, 149 (10%) 16–20 and 435 (31%) >20 years. As TFI increased, clean intermittent catheterization (CIC) declined (55% 1–5 vs 45% >20 years, p <0.001) and IDC increased (16% 1–5 vs 21% >20 years, p <0.001). On multivariable analysis, increased TFI was associated with fewer bladder symptoms at >20 years from injury (−3.21 [CI −1.29, −5.14, p <0.001]) and better satisfaction (6–10 years −0.20 [CI −0.41, 0.01, p=0.070], 11–15 years −0.36 [CI −0.60, −0.11, p=0.002], 16–20 years −0.59 [CI −0.86, −0.32, p <0.001], >20 years −0.85 [CI −1.07, −0.63, <0.001]).Conclusions:After SCI, CIC decreases and IDC increases over time; however, increasing TFI is associated with reduced urinary symptoms and improved bladder-related satisfaction.
