Anterior urethral valves are rare causes of urinary obstruction in boys. Surgical treatment leads to good long-term outcomes and normal renal function.

Area of Science:

  • Pediatric Urology
  • Congenital Anomalies
  • Urethral Obstruction

Background:

  • Anterior urethral valves are rare congenital obstructive lesions in male children.
  • These valves can cause a range of symptoms from mild voiding difficulties to severe renal impairment.

Observation:

  • This study reviewed four pediatric cases of anterior urethral valves.
  • Presentations varied from antenatal findings to postnatal symptoms like poor urinary stream, frequency, and dysuria.

Findings:

  • Diagnosis was confirmed via micturating cystourethrogram (MCU) or cystoscopy.
  • All patients underwent successful cystoscopic ablation of the valves.
  • One patient required additional surgery for postablation stricture and vesicoureteric junction obstruction.

Implications:

  • Early evaluation of the anterior urethra is crucial in male children with suspected infravesical obstruction.
  • Surgical intervention, including transurethral ablation or open resection, is the standard treatment.
  • Long-term follow-up indicates good urinary stream, normal renal function, and absence of incontinence or infections.
