S. Pomer et al., THE INVAGINATION-METHOD FOR THE MICROSURG ICAL EPIDIDYMOVASOSTOMY - OPERATIVE TECHNIQUE AND EXPERIMENTAL-STUDY OF PATENCY, Aktuelle Urologie, 25(2), 1994, pp. 88-92
To improve the results of epididymovasostomy, a technique of invaginat
ion of a single epididymal loop into the vas deferens was developed in
the rat. The epididymal loop is inserted after its fenestration into
the lumen of the vas by pushing the needle with the ends of a U-turn s
titch into the lumen and through the vas wall and then tying the ends
outside. Compared to the commonly used end-to-side anastomosis, this t
echnique proved to be time-saving, showed better patency rates and was
easier to learn than the conventional method. In addition, anastomose
s at the proximal level of the caput epididymis, as yet not practicabl
e due to the small size of the tubules and considered to be technicall
y too difficult, can also be performed.
