Idiopathic Renal Vein Varicosities

Abstract
Two cases of idiopathic peripelvic renal vein varicosities are reported. From a literature review the aethilogy, incidence, symptomatology, radiographic appearance and treatment of this lesion is elucidated. The importance of selective renal vein phlebography in the evaluation of unexplained hematuria and filing defects in the excretory urogram is illustrated.
