A Rare Case Presentation: Intravesical Catheter Knotting

Area of Science:

• Pediatric Urology
• Diagnostic Imaging
• Medical Device Complications

Background:

• Urethral catheterization is a frequent invasive procedure in pediatric care.
• Voiding cystourethrogram (VCUG) is a standard fluoroscopic diagnostic tool for evaluating pediatric urinary tract infections.
• VCUG necessitates urethral catheterization for contrast agent instillation.

Observation:

• A rare complication involving intravesical catheter knotting was observed during a VCUG procedure.
• The knotting occurred within the urinary bladder.
• This event was associated with the standard practice of urethral catheterization for VCUG.

Findings:

• The case details the occurrence of a knotted urinary catheter within the bladder.
• This represents a rare, but significant, complication of the VCUG procedure.
• The knotting complication underscores the risks inherent in pediatric urethral catheterization.

Implications:

• Highlights the need for vigilance regarding potential complications during pediatric urinary catheterization.
• Suggests a review of techniques or catheter types to mitigate knotting risks in VCUG.
• Emphasizes the importance of reporting rare adverse events in pediatric urology for improved patient safety.
