Extended Varicocelectomy Using Blue Dye

Kang, Yun Seog; Han, Sang Won

Abstract

Varicocele is the most common correctable cause of infertility, however current varicocelectomy carries high incidence of recurrences and postoperative complications. Thus a new method which can minimize recurrences and postoperative complications is devised, by performing varicocelectomy using intraoperative injection of blue dye. Followings are benefits of blue-dye varicocelectomy, first, small-caliber internal spermatic veins, not readily visible at intraoperative venography, can be easily identified. The testicular artery and veins can be easily differentiated without using the magnifying devices. Obviously it is radiation-free, and utilizes readily available substance (i.e. methylene blue or indigocarmine) and can preserve internal spermatic artery and lymphatics. This method can be applied successfullyin pediatric patients with previous varicocelectomy and inguinal operation.
