Anatomical Variations Of Branching Pattern Of Main Renal Artery In Hilum And Prehilar Area

ABSTRACT

The hila and adjacent pre-hilar parts of 72 kidneys (35 right and 37 left) isolated from formalin fixed cadaverswere examined. The hilum and prehilar area of each kidney was dissected to observe the total number ofbranches of the main renal artery. This information is useful in nephron sparing surgeries such as partialnephrectomy by laparoscopic approach. Subsequently, prehilar branching of the main renal artery before itenters the hilum was observed in 48.6% of kidneys with a higher incidence of 51.3% in left kidneys as comparedwith the incidence of the right side (45.7%). We further observe the variations of branching patterns in the mainrenal artery and calculate the incidences. Finally, our results are compared with that of similar studies conductedpreviously.
