Abstract

The function of a new experimental microsurgical model of tubulovasostomy is evaluated. The model is represented by an end-to-end tubulodeferential anastomosis after removal of the proximal (juxtaepididymal) half of the vas deferens and segmental unfolding of the distal part of the epididymal tubule. Both anastomosed segments are evaluated for responsiveness to norepinephrine and field stimulation. The results are discussed in terms of accurate selection of segments to be anastomosed on the basis of their morphofunctional correlates; in fact, it seems worth replacing the segments removed only with others endowed with equivalent properties.

摘要

对一种新的显微外科输精管吻合术实验模型的功能进行评估。该模型的特点是在切除输精管近端（附睾旁）一半并将附睾管远端进行节段性展开后进行端端输精管-输精管吻合。对两个吻合段进行去甲肾上腺素反应性和场刺激评估。根据吻合段形态功能相关性准确选择吻合段进行讨论；实际上，似乎值得仅用具有同等特性的其他段来替换切除的段。
