Normal and Variant Anatomy of Renal Hilar Structures and its Clinical Significance

Advanced imaging techniques have resulted in increasing use of minimally invasive approaches for nephron sparing surgeries of kidney. Need for precise knowledge of normal and variant anatomy of vascular pedicle of kidney is thus justified. Ample literature is available on the variations in the intra...

In majority (73%), the arrangement was not according to the normal textbook description i.e. renal vein, renal artery and pelvis arranged antero-posteriorly.
