The aim of this study was to describe the radiological features of simple or dilated (syringocele) Cowper's ducts in a large paediatric population.
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.
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.
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.
本研究旨在描述大量儿科人群中单纯性或扩张性（尿道球腺囊肿）尿道球腺导管的放射学特征。
对过去24年中进行的排尿性膀胱尿道造影检查进行评估，特别考虑尿道形态。这些检查用于研究各种可能的泌尿系统疾病。
共有1676名男童（年龄：新生儿至18岁）接受了2340次排尿性膀胱尿道造影检查。在9名儿童（0.53%）中观察到尿道球腺导管显影——6名（0.35%）表现为与膜部-球部尿道下缘平行的细的不透射线影像，3名（0.18%）表现为扩张结构（尿道球腺囊肿）；这是导致明显排尿问题的原因。
尿道球腺导管显影——即使罕见——在儿科患者排尿性膀胱尿道造影检查中也必须被视为一种可能的解剖学发现。在大多数情况下，这是一个无病理意义的附带发现，但在某些情况下，它可能是排尿障碍的一个可能原因。
