Single system ureteral ectopia in boys can mimic posterior urethral valves, causing bladder outlet obstruction. Surgical intervention, including reconstruction, is crucial for managing this rare anomaly.

Area of Science:

  • Pediatric Urology
  • Congenital Anomalies
  • Urological Surgery

Background:

  • Ureteral ectopia with renal dysplasia is common in girls with ureteral duplication.
  • Single system ureteral ectopia is a rare anomaly, more prevalent in boys.
  • This condition can lead to significant clinical challenges.

Observation:

  • This study reports on 6 boys with single system ureteral ectopia into the prostatic urethra.
  • Patients presented with radiological and clinical signs of bladder outlet obstruction.
  • Antenatal ultrasounds identified abnormalities, and postnatal studies suggested obstruction.

Findings:

  • Ectopic ureters were found inserting into the prostatic urethra in all 6 boys.
  • Dilated distal ureters elevated the bladder neck, causing obstruction.

  • Surgical management involved nephrectomy or nephroureterectomy with urethral reconstruction.
  • Two younger boys developed voiding dysfunction post-surgery.

    • Implications:

    • Single system ectopic ureters in boys can present atypically, resembling posterior urethral valves.
    • Surgical treatment should address the ectopic ureter and reconstruct the prostate.
    • Long-term voiding dysfunction is a potential complication requiring monitoring.
