The diagnosis of azoospermia or severe oligospermia that is made using conventional techniques (testicular biopsy, epididymal exploration, and vasovesiculography) may in some cases remain a dilemma. In such circumstances, post-testicular causes of obstruction must be evaluated. Following the clinical experience acquired in a selected population of 150 severely infertile subjects, the total sperm count in the fluid obtained from the bladder after a seminal tract washout during vasovesiculography has proved to be a valid tool to diagnose the location of the (sub-)obstruction in the seminal tract in complicated cases. Some representative cases are presented. In particular, seminal tract washout (STW) helps to identify functional distal seminal tract emptying disturbances and epididymal incomplete obstruction.
使用传统技术（睾丸活检、附睾探查和输精管造影）诊断无精子症或严重少精子症在某些情况下可能仍然是一个难题。在这种情况下，必须评估睾丸后梗阻的原因。根据在150名严重不育受试者的特定人群中获得的临床经验，输精管造影期间精道冲洗后从膀胱获得的液体中的总精子计数已被证明是诊断复杂病例中精道（亚）梗阻位置的有效工具。本文介绍了一些典型病例。特别是，精道冲洗（STW）有助于识别功能性远端精道排空障碍和附睾不完全梗阻。
