Retention cysts arising from obstructed Cowper's ducts are rare lesions of the anterior urethra. Five cases are reported, 3 in male infacts and 2 in young boys. In children and adults the cysts may cause dysuria, urinary frequency, or urinary retention. The etiology of Cowper's duct cysts remains uncertain, but both congenital and acquired cysts have been described. The radiographic findings are characteristic: a smooth, rounded filling defect is seen on the ventral wall of the proximal bulbous urethra during voiding cystourethrography. After fulguration of the cyst, urethrography may reveal reflux into a dilated Cowper's duct.
由受阻的考珀腺管引起的潴留囊肿是前尿道的罕见病变。本文报告了5例，其中3例为男婴，2例为幼童。在儿童和成人中，囊肿可能导致排尿困难、尿频或尿潴留。考珀腺管囊肿的病因尚不确定，但先天性和后天性囊肿均有相关描述。影像学表现具有特征性：排尿性膀胱尿道造影时，在近端球部尿道的前壁可见光滑、圆形的充盈缺损。囊肿电灼术后，尿道造影可能显示造影剂反流至扩张的考珀腺管。
