Address   for   Correspondence:    Mr.   Ajay   Babu   Kannabathula,   Assistant   Professor,      Anatomy   Department   ,   Heritage   Institute   of   Medical      sciences,         Varanasi   -           221311, Uttar Pradesh, India.   E-Mail:  ajaykbabu57@gmail.com ABSTRACT The   development   of   the   renal   vessels   account   for   the   fact   of   the   complicate   development   of   the   kidney.   The   unilateral   bifid   ureter   with   associated   bilateral renal   vascular   variations   in   routine   cadaveric   dissection.   The   bifid   ureter   may   develop   due   to   delayed   development   of   the   metanephric   tissue   or   a   relatively rapid   development   of   the   uretric   bud.   The   anatomical   variations   of   the   renal   collecting   system   associated   with   renal   vessels   are   of   great   importance   for surgical approaches radiology other evaluative methods like cystoscopy and retrograde pyelography and renal transplantation KEY WORDS:  Kidney- Double Renal pelvis - Ureter - Renal Arteries - Renal Veins, Hilar structures variations.
