[Surgical results of epididymovasostomy and vaso-vasostomy].

In the Urology Clinic of the University of Hamburg 326 epididymo-vasostomies have been done. A follow-up of 241 men was possible. Bilateral anastomosis resulted in a 47% permeability; after unilateral recanalisation a patency-rate of 32% was obtained. Vaso-vasotomy after vasoresection was performed in 56 men. Following a splinted one-layer anastomosis, which we abandoned in the meantime, patency was obtained in 64% of patients. Current techniques in one or two-layers without a splint resulted in a 88% permeability. The double layer anastomosis does not offer an advantage over the one-layer method.
