精索静脉曲张(Varicocele,VC)是一种外周血管疾病,为各种原因引起的精索内静脉血液回流受阻及反流、瓣膜失效而致蔓状静脉丛扩张、伸长、弯曲。一般病变较轻者可无明显临床表现,症状较重者主要表现为患侧睾丸迂曲包块、疼痛坠胀,步行或站立位过久时症状可加重。它是导致男性不育的常见原因,其中约21%~41%的患者因不育而就诊。因双侧睾丸静脉系统间有丰富的吻合支,所以单侧发生VC往往也会导致健侧的睾丸损害~([1])。现普遍认为认
Varicocele (VC) is a type of peripheral vascular disease that hinders and reflows blood flow to the spermatic vein due to various causes. The varicocele causes expansion, elongation, and curvature of the varicocele due to failure of the valve. The lesser general lesion may have no obvious clinical manifestations, the symptoms are mainly manifested as ipsilateral testicular tortuous mass, pain bulge, walking or standing position for too long may aggravate the symptoms. It is a common cause of male infertility, of whom about 21% to 41% of patients treated for infertility. Due to a rich anastomosis between the bilateral testicular venous system, unilateral VC may also cause contralateral testicular damage ~ ([1]). Now generally recognized
