Intradetrusor OnabotulinumtoxinA Injections Ameliorate Autonomic Dysreflexia while Improving Lower Urinary Tract Function and Urinary Incontinence-Related Quality of Life in Individuals with Cervical and Upper Thoracic Spinal Cord Injury
Bibliographic record
Abstract
Pilot data of our phase IV clinical trial (pre/post study design) highlighted a beneficial effect of intradetrusor onabotulinumtoxinA (200 IU) injections to reduce autonomic dysreflexia (AD) in individuals with chronic spinal cord injury (SCI) at T6 or above. After trial completion, we assessed whether our primary expectation (i.e., decrease of AD severity in 50% of participants during urodynamics [UDS]) was met. Secondary outcome measures were reduction of spontaneous AD in daily life as well as amelioration of AD-related and urinary incontinence-related quality of life (QoL). In addition, we conducted injury-level–dependent analysis—i.e., cervical and upper thoracic—to explore group-specific treatment efficacy. Post-treatment, AD severity decreased in 82% (28/34) of all participants during UDS and in 74% (25/34) in daily life assessed with 24-h ambulatory blood pressure monitoring. In addition, urinary incontinence-related QoL was improved, cystometric capacity was increased, and maximum detrusor pressure during storage was reduced (all p < 0.001). Further, the treatment was well tolerated, with only minor complications (grade I [ n = 7] and II [ n = 7]) in accordance with the Clavien-Dindo classification recorded in 11 individuals (cervical n = 9, upper thoracic n = 2). Injury-level–dependent analysis revealed lower incidence (cervical n = 15/23, upper thoracic n = 6/11) and lesser severity (cervical p = 0.009; upper thoracic p = 0.06 [Pearson r = −0.6, i.e., large effect size]) of AD during UDS. Further, reduced AD severity in daily life, improved urinary incontinence-related QoL, greater cystometric capacity, and lower maximum detrusor pressure during storage (all p < 0.05) were found in both groups post-treatment. Intradetrusor onabotulinumtoxinA injections are an effective and safe second-line treatment option that ameliorates AD while improving lower urinary tract function and urinary incontinence-related QoL in individuals with cervical and upper thoracic SCI.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
