Abstract: (777 Views)
Objective The primary aim of this study is to evaluate the effectiveness of ultrasound-guided urethral balloon dilation (UBD) in improving voiding function in patients with spinal cord injury (SCI)-related urinary retention, and the key secondary aims are to assess the impact of UBD on psychological status and health-related quality of life.
Materials & Methods A randomized controlled trial based on the Zelen design will be conducted. A total of 74 patients with SCI-related urinary retention will be recruited and randomized into a conventional rehabilitation group or a UBD treatment group. Primary outcomes include post-void residual (PVR) urine volume, voiding diary data, and urodynamic parameters. Secondary outcomes include quality of life (SF-Qualiveen), bladder symptom scores (neurogenic bladder symptom score [NBSS], core lower urinary tract symptom score [CLSS]), psychological status (the hospital anxiety and depression scale [HADS]), and ultrasonographic assessments of urethral structure and mobility (e.g. external urethral sphincter thickness, urethral width, sphincter volume, and urethral mobility).
Results This is a protocol paper; results are not yet available and will be reported in the primary publication.
Conclusion This protocol aims to evaluate whether ultrasound-guided UBD is a feasible and clinically useful option for managing urinary retention after SCI. The findings will provide preliminary evidence to inform its future clinical application.
