A novel technique for vas deferens transection repairs

Abstract

The purpose of this study is to describe a technique, that is as successful as microsurgery in terms of patency rates and histopathologic assessments, and can be performed even by untrained hands in microsurgery, for repairing vas deferens injuries that can be perceived during inguinal herniorrhaphy. Thirty male Wistar-Albino rats were randomly allocated to five groups. In control group, the vas deferens was harvested without any surgical intervention (Group 1) and in sham group the vas was harvested after a limited dissection (Group 2). Three suture approximation technique was carried out in Group 3, and a novel vasovasostomy technique was carried out by using a hypodermal needle in Groups 4 and 5, with polypropylene and polyglactin 910 (rapid vicryl), respectively. Results were evaluated in terms of operative time, patency and flow rates, inflammation and sperm granuloma. The mean operative times for hypodermal needle assisted approximation of Groups 4 and 5 were found significantly less than Group 3. The compared results of the groups in terms of patency, flow rate, inflammation and spermatic granuloma indicated Group 4 to be superior to the other groups. We have found the hypodermal needle assisted approximation technique to be easier, less time consuming and cost effective. With these promising results, this modus operandi can be described as an appropriate technique for vas deferens transection repairs.
