[Ureteral triplication]
Ureteral triplication, a rare anomaly, can present with an ectopic ureterocele. Accurate presurgical diagnosis is challenging, often requiring intraoperative findings for complex cases of urinary tract anomalies.
Area of Science:
- Urology
- Pediatric Surgery
- Medical Imaging
Background:
- Ureteral triplication is an exceptionally rare congenital anomaly.
- Its co-occurrence with an ectopic ureterocele is highly unusual and presents diagnostic challenges.
Observation:
- A male patient presented with recurrent urinary tract infections and left vesicoureteral reflux.
- Initial investigations suggested ureteral duplication, but a third ureter was identified during vesicostomy.
Findings:
- The third ureter terminated in an ectopic ureterocele associated with an upper pole ectopic kidney.
- This case highlights the complexity of diagnosing rare urinary tract malformations.
Implications:
- Accurate presurgical diagnosis of such complex pathologies is difficult.
- Surgical treatment requires individualized planning based on renal function and ureteral anatomy.
