Insights
This study reports on two girls with a rare congenital anomaly: a single ectopic ureter opening into the proximal urethra. This condition caused small, hydronephrotic kidneys and dilated ureters, confirmed by imaging.
Area of Science:
- Pediatric Urology
- Congenital Anomalies
- Renal Imaging
Background:
- Ectopic ureters are congenital anomalies where the ureter does not enter the bladder at the normal trigone location.
- While ectopic ureters are known, a single ureter inserted into the proximal urethra is a rare presentation.
Observation:
- Two pediatric cases presented with a single ureter inserting into the proximal urethra.
- Abdominal ultrasonography revealed small, hydronephrotic kidneys in both patients.
- Associated ureters were noted to be dilated and terminated in the proximal urethra.
Findings:
- The primary finding was a unilateral ectopic ureter terminating abnormally in the proximal urethra in two female patients.
- Renal ultrasonography demonstrated significant hydronephrosis and reduced kidney size, indicating potential renal dysplasia or obstruction.
- Voiding cystourethrogram (VCUG) confirmed the diagnosis, visualizing the ectopic ureter's course and termination point.
Implications:
- This case report highlights the importance of considering proximal urethral insertion for ectopic ureters in pediatric patients with renal anomalies.
- Early diagnosis through imaging modalities like ultrasonography and VCUG is crucial for appropriate management and preventing long-term renal damage.
- Understanding this specific ectopic ureter variant aids in surgical planning and prognosis for affected individuals.
Abstract:
Two girls, each with a single ectopic ureter inserted into the proximal urethra, are reported. Abdominal ultrasonography showed that the involved kidneys were small and hydronephrotic. The associated ureters were dilated and opened into the proximal urethra. Diagnosis was confirmed by voiding cystourethrogram.
