摘要
目的：为输精管外科、尤其是长段输精管丢失再通提供解剖学基础。方法：观察18具成人尸体的输精管行程，测量各段输精管的长度及输精管末端至外环的距离。结果：输精管从外环经内环到壶腹，行程中绕了个大弯。使输精管从外环穿出，消除该弯曲，可缩短输精管6．1～12．9（9．31±1．30）cm。输精管各段的长度分别为：附睾段3．2～5．6（4．53±0．79）cm，阴囊段4．5～9．5（7．31±1．78）cm，腹股沟段4．4～7．5（5．52±0．74）cm，后腹膜段12．5～19．5（16．75±1．87）cm，壶腹段2．9～3．8（3．63±0．23）cm。输精管长度、各段长度、两侧对比差异无显着性。结论：①游离输精管使之直接从外环穿出可缩短输精管行程6．1～12．9（9．31±1．30）cm，这是长段输精管丢失缩短行程再通的解剖学基础。②两侧输精管各段及总长差异无显著性。③输精管的外科手术与各段位置密切相关。
Objective： Studying on the routes of vas deferens to provide anatomy basis for surgical operation, especially, reconstruction of long segment loss of vas deferens. Methods ： The routes of vas deferens were observed and anatomic distances along epididymal, infrainguinal, inguinal, retroperitoneal and ampullar segments of vas dcferens, the distances from external ring to extremity of vas defcrens were measured respectively in 18 formalin fixed adult cadavers. Results： The vas deferens have a large curve from external ring to extremity in its route, draw it out from the external ring. Eliminating this curve will allow to shorten this segment of vas deferens for vasovasostomy by 6.1- 12.9（9.31±1.30） cm. The length of each segment of vas deferens, respectively, is epididymal： 3.2 -5.6（4.53±0.79） cm, infrainguinal： 4.5-9.5（7.31±1.78） cm, inguinal： 4.4-7.5（5.52±0.74） cm, retroperineal： 12.5- 19.5 （ 16.75±1.87） cm and ampullar： 2.9 - 3.8 （3.63±0. 23 ） cm. There was no significant differences in segment length and the distances from external ring to extremity of vas deferens between the right and left. Conclusion ： Recontruction of long segment loss of vas deferens can be performed by mobilization retroperitoneal vas deferens and draw it out from external ring. There were no significant differences in lengths of vas deferens and the distances from external ring to vassal extremity between the left and right in adults. The surgical operations of vas deferens are closely related each segment of vasa.
