Abstract

|
The selective renal angiographies were done in 105 kidneys of the healthy Koreans to determine the normal ranges of the renal arterial distribution based on the investigative methods of Graves, Lofgren and Boijsen. The study was also aimed to the radiological search of the various renal diseases such as neoplastic or inflammatory origins.
Following were the results:
1) The courses of renal artery from abdominal aorta to renal hilum were; horizontal in 80 , ascending in 5.7% and descending in 14.3% of the cases.
2) All renal arteries (right 53, left 52) were originated at the levels of first to second lumbar vertebra. Of these, 55.2% of cases had the origins at the level of the first lumbar intervertebral space, 45.7% at the level of the lower part of the first lumbar vertebra, 22.8;! at the intermediate level of the first lumbar vertebra and 26.6% at the level of the upper- part of the second lumbar vertebra. Locations of the intermediate part of the kidney were at the level of the first Iumbar intervertebral space in 32.4% and at the level of the upper part of the second lumbar vertebra in 16.2%.
3) Renal arteries had their branching proximal to the renal hilum in 49.500. Of these, 71.1% were branched to the upper pole, 7.6% to the pars intermedia, 19.3% to the lower pole and 1.9% to both the upper and lower poles of the kidneys.
4) The distributional types of renal arteries within the kidney were; basic types were in 52.4%, modified basic types in 36.2%, trifurcaticn types in 9.5% and quadrifurcaticn types in 1.9%.
5) Arterial supply of the upper pole was originated; from both the ventral and dorsal branches in 49.5%, from ventral alone in 19.00, from dorsal alone in 17.1(,´,x, directly from renal artery in 5.7%, and from both the smaller ventral and dorsal branches (which leave the renal artery at or proximal to the bifurcation into larger ventral and dorsal branches) in 8.6%.
6) Blood supply to the pars intermedia of kidney was mostly derived from the ventral branch of renal artery. It was found that the branch sent independent segmental branches to each of the 3rd, 4th and 5 th ventral pyramids in 4.8 / and that it gave off one independent branch to one pyramid and one common branch to the other two pyramids in 55.2%.
7) Arterial branch supplying the lower pole was usually singular and was derived from the ventral branch in 67.6% and directly from the renal artery in 32.4.
