Transrectal ultrasound urodynamics (TRUSU) offers a radiation-free, cost-effective alternative for spinal cord injury patients. This study found TRUSU effective for urologic evaluation, though fluoroscopic videourodynamics identified some conditions TRUSU missed.

Area of Science:

  • Urology
  • Neurology
  • Medical Imaging

Background:

  • Spinal cord injury (SCI) frequently leads to neurogenic bladder dysfunction.
  • Urologic evaluation is crucial for managing SCI patients.
  • Conventional videourodynamics (VUD) using fluoroscopy involves radiation exposure.

Purpose of the Study:

  • To compare the efficacy of transrectal ultrasound urodynamics (TRUSU) with conventional fluoroscopic VUD.
  • To evaluate TRUSU as an alternative diagnostic tool for SCI patients.

Main Methods:

  • Seventy-seven male SCI patients underwent two videourodynamic studies: TRUSU and fluoroscopic VUD.
  • Studies were performed twice in the same session for direct comparison.
  • Transrectal ultrasound and fluoroscopy were utilized.

Main Results:

  • TRUSU provided clear visualization of fluid dynamics, facilitated EMG electrode placement, and offered detailed imaging of pelvic structures.
  • TRUSU eliminated radiation exposure and allowed for extended imaging times.
  • Fluoroscopic VUD identified bladder diverticula and vesicoureteral reflux missed by TRUSU.
  • TRUSU detected a prostate lesion and a bladder neck tumor.

Conclusions:

  • TRUSU is a valid and preferable alternative to fluoroscopic VUD for urologic evaluation in SCI patients.
  • TRUSU offers advantages in visualization, safety, and cost-effectiveness.
  • Fluoroscopic VUD remains valuable for detecting certain structural abnormalities.
