Answer

The inguinal and subinguinal approaches are those most commonly used by the vast majority of adult urologists and infertility specialists. The familiar anatomy, low morbidity, and high efficacy make these approaches almost ideal. Inguinal ligation is achieved by incising the inguinal canal down to the external inguinal ring. After cord isolation, the testicular artery is preserved and the veins of the cord are ligated and divided.

The subinguinal approach is performed in a similar fashion, but access is achieved through an incision at or near the pubic tubercle that obviates the opening of the external oblique aponeurosis. The advantages of subinguinal varicocele ligation, especially with use of magnification, include decreased pain and easier access to the spermatic cord, especially among obese men and those with a history of inguinal surgery. However, at this level, a greater number of veins are present, especially periarterial anastomosing veins, which makes subinguinal ligation technically challenging.

The use of the microsurgical technique has advanced the surgical treatment of this disorder by allowing optimal visualization. While the approach to cord isolation is no different, the 6-25X magnification facilitates the identification of small anastomosing veins that might otherwise be missed. Furthermore, the risk of testicular ischemia and testis atrophy due to inadvertent ligation of the testicular artery is greatly reduced with this improved visualization. This risk of arterial ligation can be further reduced by using a mini-Doppler ultrasound probe (Vascular Technology, Inc. [VTI] 20-MHz microvascular Doppler) with the use of a topical vasodilator.
