[Percutaneous demonstration of ectopic megaureters]

Area of Science:

• Pediatric Urology
• Diagnostic Imaging
• Minimally Invasive Surgery

Background:

• Ectopic megaureter diagnosis can be challenging, impacting timely treatment for pediatric patients.
• Accurate preoperative identification of ureteral abnormalities is crucial for surgical planning and patient outcomes.

Observation:

• A novel technique utilizing percutaneous transvesical fine needle puncture was employed.
• Sonographic visualization of a retrovesical megaureter guided the fine needle puncture.
• Antegrade ureterography with contrast and indigocarmine dye was performed.

Findings:

• The procedure successfully demonstrated the megaureter via roentgenology.
• The ectopic orifice was identified using direct vision or colposcopy in all three cases.
• This method simplifies the preoperative diagnosis of ectopic megaureter.

Implications:

• This minimally invasive approach offers a more straightforward method for diagnosing ectopic megaureter.
• Improved diagnostic accuracy can lead to better surgical planning and outcomes in affected girls.
• The technique holds potential for wider adoption in pediatric urology practices.
