Summary
This study details the first reported neonatal case of congenital giant megaureter (CGM), a rare urinary tract abnormality characterized by significant ureteral dilation. The findings highlight the varied distal ureter morphologies associated with CGM in infants.
Area of Science:
- Pediatric Urology
- Congenital Anomalies
- Urinary Tract Imaging
Background:
- Congenital giant megaureter (CGM) is a rare unilateral urinary anomaly.
- CGM is defined by congenital, focal, and segmental ureteral dilation exceeding 10 times normal diameter.
- Normal bladder volume and function are present in CGM cases.
Observation:
- This report presents the first neonatal case of congenital giant megaureter.
- The anomaly was unilateral, affecting the urinary tract.
- The patient presented with symptoms in the neonatal period.
Findings:
- A series of 21 CGM cases, including 12 in duplex systems, were analyzed.
- Distal ureter morphology in CGM varied significantly.
- Observed morphologies included near-normal caliber, ureteral stenosis, ureterocele, and complete ureteral atresia.
Implications:
- Neonatal presentation of CGM is possible and requires early recognition.
- The diverse distal ureter morphologies underscore the complexity of CGM.
- Understanding these variations is crucial for accurate diagnosis and management of neonatal urinary anomalies.
