This report describes a case with an ectopic ejaculatory duct opening into the bladder trigone in Zinner syndrome, congenital unilateral renal agenesis, and an ipsilateral seminal vesicle cyst.
The patient was identified when no left kidney was detected in the fetal period. Abdominal ultrasonography and pelvic plain MRI at 6 months old revealed a 10-mm cystic lesion on the dorsal aspect of the bladder. Cysto-urethroscopy at 1 year old revealed a rather short posterior urethra and right and left inferior crests extending from the posterior urethra beyond the bladder neck. The ejaculatory duct opening was identified on the bladder trigone.
Anatomical abnormality of the ejaculatory duct may represent a cause of infertility and ejaculatory dysfunction in Zinner syndrome. Endoscopic evaluation should be performed for this rare anomaly, even in children.
本报告描述了一例患有齐纳综合征(Zinner syndrome)的病例,其射精管异位开口于膀胱三角区,同时伴有先天性单侧肾缺如和同侧精囊囊肿。
该患者在胎儿期未检测到左肾。6个月大时的腹部超声检查和盆腔平扫磁共振成像(MRI)显示膀胱背侧有一个10毫米的囊性病变。1岁时的膀胱尿道镜检查显示后尿道较短,左右下嵴从后尿道延伸至膀胱颈以外。射精管开口位于膀胱三角区。
射精管的解剖异常可能是齐纳综合征患者不孕和射精功能障碍的原因。即使是儿童,对于这种罕见异常也应进行内镜评估。
