[Routing reseach of vas deferens on anatomy and clinical application].
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 deferens, the distances from external ring to extremity of vas deferens 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, retroperitoneal: 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.


CONCLUSIONS
Reconstruction 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.
