Cowper's glands and ducts: radiological findings in children.

PURPOSE: The aim of this study was to describe the radiological features of simple or dilated (syringocele) Cowper's ducts in a large paediatric population.

MATERIALS AND METHODS: Voiding cystourethrography procedures performed during the past 24 years were evaluated taking into special account urethral morphology. The procedures were performed to study all sorts of possible urinary affections.

RESULTS: A total of 1,676 male children (age: newborn to 18 years) underwent 2,340 voiding cystourethrographies. Opacification of Cowper's ducts was observed in nine children (0.53%) - in six (0.35%) as a thin, radiopaque image running parallel to the inferior edge of the membranous-bulbar urethra and in three (0.18%) as a dilated structure (syringocele); this was a source of significant voiding problems.

CONCLUSIONS: Opacification of Cowper's ducts - even if rare - has to be recognised as a possible anatomical finding during voiding cystourethrography in paediatric patients. An accessory finding devoid of pathological meaning in most cases, it can, however, be a possible cause of voiding disorders in some instances.
