Insights
Cowper's duct syringocele, a rare cause of urethral obstruction in boys, can present with severe voiding issues. Surgical incision of the bulbous ostia effectively relieved obstruction and improved urinary flow in a pediatric patient.
Area of Science:
- Pediatric Urology
- Urethral Obstruction
- Congenital Anomalies
Background:
- Cowper's duct syringocele is an uncommon cause of urethral obstruction in children.
- It is often overlooked and can lead to significant voiding difficulties.
Abstract:
Cowper's duct syringocele is an uncommon and often overlooked cause of urethral obstruction in children. We report a 7-year-old boy who had experienced severe voiding difficulty, frequency, and urgency for three months and could void only while sitting. Ultrasonography, computed tomography, magnetic resonance imaging, and voiding cystourethrography were nondiagnostic. Cystourethroscopy revealed a prominent posterior urethral crest and verumontanum, two ectopic pinpoint ostia in the bulbous urethra, and a blind membranous pouch. Incision of the bulbous ostia released abundant proteinaceous material, relieved the obstruction, and improved postoperative uroflowmetry. Syringocele should be considered in boys with unexplained infravesical obstruction.
