Absence of a vas deferens is a marker for more serious anomalies of the genitourinary tract. It is highly probable that the ipsilateral kidney, ureter or bladder is deformed or absent. The complete physical examination and the preoperative examination for vasectomy should include palpation to identify the vas. The existence of an accessory vas could explain failure of azoospermia following a ligation procedure.
输精管缺如是泌尿生殖道更严重异常的一个标志。同侧肾脏、输尿管或膀胱很可能存在畸形或缺失。输精管结扎术前的全面体格检查应包括触诊以确定输精管。副输精管的存在可能解释结扎手术后无精子症的失败。
