Antegrade pyelography in ureteric duplications with obstructed upper segments
Journal of the Canadian Association of Radiologists
|December 1, 1983
Summary
This study used fluoroscopic-guided percutaneous puncture and antegrade pyelography to diagnose complete ureteral duplication in infants. The method effectively confirmed the condition and visualized the affected ureter.
Area of Science:
- Pediatric Urology
- Diagnostic Imaging
- Congenital Abnormalities
Background:
- Complete ureteral duplication can lead to urinary tract obstruction, particularly in neonates.
- Accurate diagnosis is crucial for appropriate management and preventing renal damage.
- Excretory pyelography and ultrasonography can suggest ureteral duplication but may require definitive confirmation.
Observation:
- Three children, including two neonates, with suspected complete ureteral duplication underwent the procedure.
- The technique involved percutaneous puncture under fluoroscopic guidance.
- Antegrade pyelography was performed following the puncture.
Findings:
- The fluoroscopic-guided percutaneous puncture with antegrade pyelography proved to be a simple and definitive diagnostic method.
- The procedure successfully confirmed the diagnosis of complete ureteral duplication.
- It clearly demonstrated the course, termination, and effects of the dilated ectopic ureter.
Implications:
- This technique offers a reliable approach for diagnosing complex ureteral anomalies in pediatric patients.
- Early and accurate diagnosis facilitates timely intervention, potentially improving outcomes.
- The study highlights the value of minimally invasive imaging in pediatric urology.
