Prediction Model for Neurogenic Bladder Recovery One Year After Traumatic Spinal Cord Injury.

Area of Science:

• Neuroscience
• Urology
• Rehabilitation Medicine

Background:

• Neurogenic bladder is a frequent and burdensome complication following spinal cord injury (SCI).
• Predicting bladder recovery is crucial for managing patients with SCI.

Purpose of the Study:

• To develop a predictive model for neurogenic bladder recovery one year after traumatic SCI.
• To identify key baseline parameters associated with complete bladder function recovery.

Main Methods:

• Utilized the National Spinal Cord Injury Model Systems database for patients with traumatic SCI.
• Developed a multivariable logistic regression model using imputed data for complete bladder recovery at one year.
• Included baseline parameters such as sacral sensation, ASIA impairment score, and bowel function.

Main Results:

• Identified 2515 patients with abnormal bladder function at baseline; 16.6% recovered function within one year.
• Key predictors of recovery included sacral sensation, ASIA score, bowel function, sphincter contraction, anal sensation, S1 motor scores, and rehabilitation duration.
• The prediction model demonstrated a high discriminative capacity of 90.5%.

Conclusions:

• A robust prediction model for one-year neurogenic bladder recovery post-SCI was successfully developed.
• The model exhibits significant predictive power, offering utility in patient counseling, research, and clinical management.
• This tool can aid in optimizing care strategies for individuals with SCI.
