Background
Bladder and urethral pathologies can result in considerable quality of life changes. Retrograde urethrogram (RUG) and voiding cystourethrogram (VCUG) examinations remain important diagnostic tools in the evaluation of urethral and bladder pathologies.
Educational Goals / Teaching Points
The purpose of this exhibit is to review common indications for performing RUG and VCUG examinations, practical techniques and optimal patient positioning during acquisition, identification of normal urethral and bladder anatomy on fluoroscopy, pathologies detectable with RUG and VCUG examinations, and pearls and pitfalls during acquisition.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit will demonstrate normal urethral and bladder anatomy on RUG and VCUG examinations, with special attention to normal anatomy that can be mistaken for pathology. There will be a review of indications for each examination and the utility of combining examinations. This exhibit will also discuss the etiology, clinical presentation, and key RUG and VCUG imaging findings of urethral and bladder pathologies, including acute traumatic injuries, post-surgical changes, fistulas, masses, urethral strictures, and vesicoureteral reflux.
Conclusion
RUG and VCUG examinations can be useful in the evaluation of both traumatic and atraumatic pathologies. Familiarity with common indications, RUG and VCUG image acquisition techniques, and imaging findings can aid the radiologist in forming accurate diagnoses of urethral and bladder pathologies.
