Abstract
To assess whether an experimental endoscopic study of the vasa deferentia is feasible. Endoscopic study of the seminal tracts was carried out during three vasectomies performed prior to open prostatectomy. A flexible endoscope, 0.56 mm in diameter, with a depth of field of 5 mm and a 3000 fiberoptic light source was used for the procedure. Endoscopy was possible for the inguinoscrotal segment of the vas deferens. The curvature at the opening of the internal inguinal ring proved impassable. Endoscopy of the vas deferens is possible with a 0.56-mm flexible endoscope, but because of the extreme curvature of the vas at the inguinal ring, the complete vas cannot be evaluated in an antegrade manner.
