ABSTRACT

Background: Although the number of patients receiving vasoepididymostomies is gradually increasing, these individuals are limited in the recent advanced assisted reproductive technology (ART) era. A novel technique involving vasoepididymostomy with epididymal tubular invagination has been reported. We attempted to define the results of this method and to compare them with the conventional end-to-side technique in patients with suspected epididymal obstruction and no previous history of vasectomy. Methods and Results: Eight eligible triangulation end-to-side vasoepididymostomy procedures performed on five azoospermic patients exhibiting either unilateral or bilateral epididymal obstruction are described. The overall patency rate following operation was 100% (five of five). Two pregnancies were achieved by natural intercourse and one was accomplished via artificial insemination. A single pregnancy was obtained with an intracytoplasmic sperm injection using frozen-thawed sperm collected during the operation. Conclusion: Vasoepididymostomy, using the triangulation technique for epididymal obstruction, resulted in an earlier patency in all patients. This method may afford advantages when compared with the conventional end-to-side approach; however, larger subject populations are required in order to assess further the efficacy of this procedure. In addition, long-term follow up is necessary. (Reprod Med Biol 2003; 2: 101-104). More... »
