Description

The invention relates to medicine, more specifically to urology, in relation to the formation of anastomoses and suturing during operations on the family duct.

The aim of the invention is to improve the tightness and adequacy of the comparison of the walls and the lumen of the duct by creating a cuff of adventitia casing turned in the iroximal direction, layer-by-layer dissection of the duct at the edges of the contractile muscle fibers of the outer longitudinal layer, sewing it proximal. the end with a similar layer and adventitial sheath of the distal end and the second row of adventitial transverse U-shaped seams with a distal-turnable cuff.

The left-sided oblique incision in the downspace region made access to the spermatic cord. The spermatic cord is opened along the fluted probe. The vas deferens was isolated by a stupid path, and arteries, veins and nerves were removed from it. 2 mm distal to the intended excision site, a circular incision to the minor sheath dissected the adventitial sheath and turned in a proximal direction at a distance of 1 cm. Cut the outer longitudinal muscular layer on both sides of the intended excision site. The duct was resected along the contracted edge of the constrictor fibers. The anesthetic edges are mapped, the first row consisting of four nodal seams is superimposed on the adventitia membrane and the outer longitudinal distal distal layer and the outer lining; the end layer of the proximal segment of the duct. Adventitious exoprosthesis is formed by turning in the distal direction of adventitia

5 - the formation of an adventitial cuff and the imposition of a second row of U-shaped adventitio-adventitial seams with a transverse position of the hidden part of the suture line

The method is carried out as follows.

Distal to the occluded area of the vas deferens, dissect the adventitia and turn it in the proximal direction for the length of the intended resection. A circular longitudinal incision is dissected from both sides of the outer longitudinal sac layer and along the edge of its contracted fibers a resection of the occluded section is made. Then, firstly, adjacent adventitious membrane and outer longitudinal miniature layer of the distal section with the outer longitudinal muscle layer of the proximal section are stitched. The adventitial cuff is turned in the distal direction and a second row of adventitio-adventitial U-shaped sutures is applied to fix it in such a way that part of the suture line is hidden in the transverse direction.

The second row of continuous U-shaped adventitio-adventitial sutures is footed. Fourteen days after the operation, the duct patency was determined radiographically. Macroscopically duct viable. In a semen smear, spermatozoa are determined from an incision distal to the site of the anastomosis.

The proposed method creates good conditions for a high-quality passable and hermetic junction of the seminal duct and provides optimal conditions for reparative regeneration.

The application of the proposed method provides primary healing of the anastomosis with the formation of a thin linear scar and the rapid restoration of the physiological function of sperm transport.
