Congenital posterior urethral diverticulum, a rare condition, can lead to infections and stones. Dynamic MRI offers a novel imaging approach for this anomaly, complementing traditional methods like voiding cystourethrogram.
Area of Science:
- Pediatric Urology
- Diagnostic Imaging
- Medical Device Technology
Background:
- Congenital posterior urethral diverticulum (CPUD) is a rare congenital anomaly of the male urethra.
- CPUD can lead to complications such as urinary tract infections and calculus formation.
- Conventional diagnostic imaging relies on voiding cystourethrogram (VCUG).
Observation:
- A case of CPUD with secondary calculi is presented.
- Dynamic magnetic resonance imaging (MRI) was utilized for patient evaluation.
- Conventional VCUG was also performed for comparison.
Findings:
- Dynamic MRI provides detailed anatomical visualization of the posterior urethra and diverticulum.
- MRI may offer complementary diagnostic information in complex CPUD cases.
- The study highlights the potential utility of dynamic MRI in evaluating CPUD.
Implications:
- Dynamic MRI may become a valuable tool in the diagnosis and management of congenital posterior urethral diverticulum.
- Further research is warranted to establish the role of dynamic MRI in CPUD.
- This case contributes to the limited literature on advanced imaging techniques for CPUD.
