To assess the association between the congenital narrowing of the bulbar urethra and syringoceles.
Eleven boys were investigated, 10 with a cystogram and 9 with video endoscopy. The video tapes were reviewed with the radiology and the relationship between the syringocele and the narrowing of the bulbar urethra (Cobb's collar) was particularly noted.
Seven of the 9 boys examined endoscopically were found to have a Cobb's collar near the proximal extent of the syringocele; the proximal extent of external sphincter appeared to be above and separate from the syringocele in all cases. Six of 10 patients had a syringocele and bulbar urethral narrowing seen at cystogram.
It would appear that syringoceles are often associated with a Cobb's collar, in keeping with the possible origin of both structures from the region of the urogenital membrane. The narrowing in the bulbar urethra may, however, be an incidental finding in many of the cases.
评估球部尿道先天性狭窄与尿道囊肿之间的关联。
对11名男孩进行了研究，其中10名进行了膀胱造影，9名进行了视频内镜检查。对录像带进行了放射学检查，并特别注意了尿道囊肿与球部尿道狭窄（科布环）之间的关系。
在接受内镜检查的9名男孩中，有7名在尿道囊肿近端附近发现有科布环；在所有病例中，外括约肌近端似乎位于尿道囊肿上方且与之分开。10名患者中有6名在膀胱造影时发现有尿道囊肿和球部尿道狭窄。
尿道囊肿似乎常与科布环相关，这与这两种结构可能均起源于泌尿生殖膜区域相符。然而，球部尿道狭窄在许多病例中可能是偶然发现。
