Why are the vas deferens and gonadal vessels ligated separately during radical orchiectomy?
allow easier identification during future RPLND.

What is intratubular germ cell neoplasia (ITGCN)?
pre-invasive lesion where abnormal germ cells are confined inside seminiferous tubules without invading surrounding tissue.
approximate incidence of synchronous bilateral testicular tumors?
Around 1%.
