The authors present the case of 4-month-old girl with a midline prepubic sinus extending from the skin overlying the pubis to the superior surface of the bladder, and continuing to the umbilicus via the median umbilical ligament. The distal portion of the exicised sinus was surrounded by concentric bundles of collagen and smooth muscle with minimal inflammatory infiltrates, which suggests a developmental origin. According to Stephens' classification, the sinus appears to be a variant of dorsal urethral duplication of Stephens type 3.
作者报告了一名4个月大女孩的病例，其耻骨前正中窦从耻骨上方的皮肤延伸至膀胱上表面，并通过脐正中韧带延续至脐部。切除的窦道远端被同心束状的胶原蛋白和平滑肌包围，炎症浸润极少，这提示其起源于发育异常。根据斯蒂芬斯分类法，该窦道似乎是斯蒂芬斯3型背侧尿道重复畸形的一种变体。
