Abstract
PURPOSE: Neurogenic bladder significantly impacts individuals after spinal cord injury. We hypothesized that there would be differences in bladder related symptoms and quality of life for 4 common bladder management methods. MATERIALS AND METHODS: In this prospective observational study we measured neurogenic bladder related quality of life after spinal cord injury. Study eligibility included age 18 years or greater and acquired spinal cord injury. Bladder management was grouped as 1) clean intermittent catheterization, 2) an indwelling catheter, 3) surgery (bladder augmentation, a catheterizable channel or urinary diversion) and 4) voiding (a condom catheter, involuntary leaking or volitional voiding). The primary outcomes were the NBSS (Neurogenic Bladder Symptom Score) and the SCI-QoL Difficulties (Spinal Cord Injury Quality of Life Measurement System Bladder Management Difficulties). Secondary outcomes were the NBSS subdomains and satisfaction with urinary function. Multivariable regression was done to establish differences between the groups, separated by level. RESULTS: Of the 1,479 participants enrolled in the study 843 (57%) had paraplegia and 894 (60%) were men. Median age was 44.9 years (IQR 34.4-54.1) and median time from injury was 11 years (IQR 5.1-22.4). Bladder management was clean intermittent catheterization in 754 cases (51%), an indwelling catheter in 271 (18%), surgery in 195 (13%) and voiding in 259 (18%). In regard to primary outcomes, in cases of paraplegia and tetraplegia an indwelling catheter and surgery were associated with fewer urinary symptoms on the NBSS compared to clean intermittent catheterization while voiding was associated with more symptoms. In paraplegia and tetraplegia cases surgery was associated with fewer bladder management difficulties according to the SCI-QoL Difficulties. In regard to secondary outcomes, surgery was associated with improved satisfaction in individuals with paraplegia or tetraplegia. CONCLUSIONS: In individuals with spinal cord injury fewer bladder symptoms were associated with an indwelling catheter and surgery, and worse bladder symptoms were noted in voiding individuals compared to those on clean intermittent catheterization. Satisfaction with the urinary system was improved after surgery compared to clean intermittent catheterization.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
