This study aims to investigate the correlation between detrusor and bladder wall thickness measured by suprapubic ultrasound and urodynamic parameters in patients with spinal cord injury. By evaluating ultrasonographic measurements alongside urodynamic findings, the study seeks to assess their relationship in a prospective cross-sectional setting.

This single-center, prospective cross-sectional observational study was conducted to evaluate the association between detrusor and bladder wall thickness measured by suprapubic ultrasound and urodynamic parameters in patients with spinal cord injury. Patients with spinal cord injury were prospectively enrolled and underwent suprapubic ultrasonography and urodynamic evaluation as part of the study protocol.

Detrusor wall thickness and bladder wall thickness were measured using suprapubic ultrasonography according to a standardized protocol. Urodynamic parameters, including detrusor pressure and other relevant measurements, were recorded during routine urodynamic assessment. The relationship between ultrasonographic measurements and urodynamic findings was analyzed to assess their correlation.

Inclusion Criteria:

1. ≥18-65 years of age
2. Traumatic and non-traumatic SCI
3. Willingness to participate and able to provide written informed consent

Exclusion Criteria:

1. Neurogenic lower urinary tract dysfunction not caused by spinal cord injury
2. History of brain surgery
3. History of augmentative urinary surgery or invasive bladder procedures (e.g., bladder tumor resection, botulinum toxin injection)
4. History of urinary tract malignancy
5. Prior overactive bladder or urinary incontinence, or prior surgery for benign prostatic hyperplasia
6. Bladder outlet obstruction
7. Cognitive impairment that would interfere with participation
8. Active urinary tract infection preventing urodynamic evaluation

Patients with spinal cord injury admitted to the inpatient rehabilitation program at Ankara Bilkent City Hospital Physical Therapy and Rehabilitation Hospital, referred to the Urodynamy Laboratory, who met the inclusion criteria and consented to participate in the study.
