  • Title: Microsurgical vasoepididymostomy: a comparison between the end-to-side anastomosis and the invagination technique.
    Author: Shekarriz M, Pomer S.
    Journal: Urol Res; 1991; 19(5):285-7. PubMed ID: 1949427.
    Abstract:
    In this study we compared the invagination technique with the commonly used end-to-side anastomosis. A total of 30 invaginations and 30 end-to-side anastomoses was performed randomly in 30 Wistar rats. We checked the patency of the anastomoses 4 months after operation by macroscopic examination, spermiogram, methylene blue injection, and X-radiography studies as well as histology. The examination of the anastomoses showed patency in 19 (63.2%) compared with 24 patent invaginations (80%). The introduction of the simple time-saving technique of invagination could be useful for clinical purposes, since it is easier to learn and to practise and might also improve the clinical results concerning the patency of anastomoses.
