V1592: Modified Intussusception Vasoepididymostomy: Does it has benefits?


Introduction and Objectives
Two-suture intussusception vasoepididymostomy does not achieve water-tight anastomosis with 4 dot sewing .We modifide the two-suture intussusception vasoepididymostomy by adding another two suture to prevent the potential leakage and decrease the late failure rate.

Between June 2012 to October 2012, 9 patients with epididymal obstructive azoospermia were enrolled in this study. In order to make the waterproof anastomosis, after two double-armed 10-0 parallel sutures were placed and epididymal tube incision was made between them as described previously, we add another two 11-0 sutures through the epididymal incision corresponding the 6 o'clock and 12 o'clock of the distal vas respectively. The six needles attached to the suture were passed into the vas lumen and brought out through the muscularis (Firstly the needle of the third, the initially two and then the fourth suture sequentially). The initially passed two sutures were tied first to achieve the intussusception, and then the other two were tied to accomplish the water-proof procedure.

A semen analysis was obtained 1 to 3 months postoperatively in 6 compliable patients, sperm were found in the ejaculates of 3of 6 (50%).

Because the follow up was too short, the modified intussusception vasoepididymostomy has not shown the evident superiority compare to two-suture intussusception vasoepididymostomy, however, further studies with large sample and long-term follow up are needed to testify the effectiveness of this technique .
