[Conservative elective surgery in kidney neoplasms]

After the good results of "necessary" conservative surgery in the treatment of kidney neoplasms (bilateral neoplasms, congenital, acquired or functional solitary kidney), conservative surgery itself has been employed as elective treatment in selected cases presenting without the overmentioned problems. The authors report two cases of elective conservative surgery in kidney neoplasm with good results after 18 and 24 months.
