Congenital unilateral absence of the vas deferens occurs in 0.5%-1.0% of males. It has been associated with various genitourinary abnormalities, including renal agenesis. We report a case of congenital unilateral absence of the vas deferens found incidentally during vasectomy in a patient with known unilateral renal agenesis.
A 24-year-old male presented to our urology clinic requesting vasectomy. His past history was significant for left renal agenesis. Following successful right vasectomy, several attempts to locate the left vas deferens were unsuccessful. We diagnosed congenital unilateral absence of the vas deferens. Follow-up semen analysis showed azoospermia.
As vasectomies are increasingly performed in outpatient settings, it is imperative that physicians be aware of this condition, which can be recognized by a simple physical exam. Recognition could prevent unnecessary surgery and prompt providers to investigate for associated abnormalities.
先天性单侧输精管缺如在0.5% - 1.0%的男性中出现。它与各种泌尿生殖系统异常有关，包括肾缺如。我们报告一例在已知单侧肾缺如的患者行输精管结扎术时偶然发现先天性单侧输精管缺如的病例。
一名24岁男性到我们的泌尿外科门诊要求行输精管结扎术。他既往有左肾缺如病史。成功进行右侧输精管结扎术后，多次尝试寻找左侧输精管均未成功。我们诊断为先天性单侧输精管缺如。后续精液分析显示无精子症。
由于输精管结扎术越来越多地在门诊进行，医生必须了解这种情况，通过简单的体格检查即可识别。识别这种情况可以避免不必要的手术，并促使医疗人员对相关异常进行检查。
