    Journal: Urologiia; 2006; (3):79-80, 82-3. PubMed ID: 16889099.
    Abstract:
    A variant of microsurgical invagination vasoepididymostomy (patent of the Russian Federation N 2195205, 2002) was developed in 2001-2004 in experiment on 21 mongrel dogs. Fourteen dogs have undergone 22 vasoepididymostomies according to the novel technique and 5 control vasoepididymoanastomoses side-to-side. The proposed operation implies deep antegrade submersion and fixation of the stump of the epididymis duct in the lumen of the deferent duct through a small slit wound of the latter. Duration of the operation is 62 +/- 3 min. Passability of the anastomosis was assessed 6 months after the operation with ejaculate microscopy, retrograde staining of the deferent ducts on the preparations and with microscopy of stained histological sections. Spermatozoa were detected in ejaculate of all the operated on dogs. By microscopy, 20 anastomoses were capable. This operation technique was introduced into clinical practice: 3 patients with epididymic obstruction were operated on. Passability recovered 1.5-2 months after the operation in two of them. Thus, this variant of invagination vasoepididymostomy is perspective for wide clinical practice.
