Radionuclide voiding cystourethrography in children can lead to misdiagnosis if the catheter tip is misplaced. Proper catheter technique and imaging control are crucial for accurate vesicoureteral reflux detection.

Area of Science:

  • Pediatric radiology
  • Urogenital imaging

Background:

  • Voiding cystourethrography (VCUG) is a standard diagnostic tool for detecting vesicoureteral reflux (VUR) in children.
  • Radionuclide voiding cystourethrography (RVUG) is a variation used for VUR assessment.

Observation:

  • A specific case highlighted a potential for misinterpretation during RVUG.
  • The issue stemmed from the catheter tip's initial placement within an open ureter ostium.

Findings:

  • This malpositioning could erroneously suggest the presence or absence of VUR.
  • The study emphasizes the critical role of precise catheter placement and vigilant imaging during the procedure.

Implications:

  • Adherence to recommended catheter techniques can prevent diagnostic errors in pediatric VUR evaluation.
