title: Varicocelectomy: incidence of external spermatic vein involvement in the clinical varicocele.
abstract: The vascular anatomy of the clinical varicocele, and the incidence of involvement of the external spermatic vein were studied. Dilation of the external spermatic vein (4 mm) was found in 49.5 percent of 93 varicoceles in 67 patients. The location of this vein, its potential involvement in a varicocele, and its management were reviewed.
