title: Microsurgical two-layer vasovasostomy. Simplified technique using hinged, folding-approximating clamp.
abstract: Microsurgical two-layer vasovasostomy appears to yield improved results over conventional methods but is not widely used because of technical difficulties. A technique is reported which utilizes a hinged folding vas approximating clamp and allows the two-layer anastomosis to be performed with greater ease because the details of the vas ends are visualized constantly. The danger of mucosal tears is lessened by posterior muscular layer approximation before mucosal approximation, thus relieving mucosal tension during suturing.
