Summary
Contrast extravasation during voiding cystourethrography (VCUG) can occur unexpectedly in patients without prior kidney issues or bladder dysfunction. This case highlights the importance of vigilance during this diagnostic imaging procedure.
Area of Science:
- Urology
- Radiology
- Medical Imaging
Background:
- Voiding cystourethrography (VCUG) is a standard diagnostic procedure for evaluating lower urinary tract abnormalities.
- Contrast extravasation, the leakage of contrast media outside the intended vascular or urinary tract, is a known but uncommon complication of VCUG.
Observation:
- A case of contrast extravasation during VCUG is presented in a patient with no history of renal failure.
- The patient also did not have a history of a non-functioning or "unused" bladder, challenging typical risk factor assumptions.
Findings:
- The occurrence of contrast extravasation during VCUG in this specific patient profile suggests that risk factors may be broader than previously recognized.
- Review of the literature on VCUG-related extravasation is provided.
Implications:
- This case underscores the need for careful technique and monitoring during VCUG, irrespective of patient history.
- Understanding the potential for extravasation in diverse patient populations can inform procedural protocols and patient counseling.
