| description | Introduction: Classically each kidney is supplied by a single
renal artery. In its course renal artery divides into anterior and
posterior division, both of these division further divide into
segmental arteries that are apical, upper, middle, lower and
posterior. Segmental arteries are representing an end artery and
they form independent renal segments. In their course they are
closely related with collecting system. So, a thorough in depth
knowledge of the variations in segmental arteries is a basic
requirement for surgeons.
Aim: To observe and investigate the anatomical variations in
arterial pattern of upper segmental renal artery and its relations
with collecting system of ducts in human kidneys.
Materials and Methods: Fifty human kidneys of both sexes
were observed and studied by corrosion cast method. Different
colour coded cast material (butyl butyrate) like red for artery
and black for collecting ducts were used. 20% solution of butyl
butyrate in acetone was injected into renal artery and ureter of
the kidneys. After polymerization (24 hours) these kidneys were
kept immersed in a bath of concentrated KOH solution at 500
C
for 24-48 hours for corrosion to obtain the endocasts. These
endocasts were cleaned and washed under running tap water
and photographed.
Results: In present study upper segmental artery was found in
49 (98%) kidneys. It was absent in 1 (2%) kidney. We observed
four types of variations in arterial pattern of upper segmental
artery namely Upper Segmental Artery Type-1 (USAT1), Upper
Segmental Artery Type-2 (USAT2), Upper Segmental Artery
Type-3 (USAT3), Upper Segmental Artery Type-4 (USAT4) and
they were found in 20 (40%), 14 (28%), 10 (20%), 5 (10%)
kidneys respectively. We also observed two different variations
in the anatomical relations between upper segmental artery
and collecting system namely Upper Segmental Artery Group
-1 (USAG1) and Upper Segmental Artery Group-2 (USAG2).
USAG1 was found in 40 (80%) kidneys and USAG2 in 9 (18%)
kidneys respectively.
Conclusion: Anatomical knowledge of these variations is very
important and useful for the uro-surgeons for best outcome and
minimal complications in and during nephrectomies, removal
of calculi, surgery of renal tumors or other various intrarenal
surgeries. |
