Jorge Villagra C. Severe growth retardation is one of the complications of chronic renal failure that is the most important factor that affects the normal social and academic integration of the uraemic child. This continues to be a problem in the post transplant period, in part caused by the continuing use of steroid immunosuppression. Objective: to evaluate the effect of using alternate day steroids on the growth of transplanted children compared with those treated with daily steroids.

Any variant in arterial supply is important to clinicians undertaking surgery or other interventional renal procedures. They arise from the abdominal aorta at the L vertebral body level, inferior to the origin of the superior mesenteric artery. The right renal artery courses inferiorly and passes posterior to the IVC and the right renal vein to reach the renal hilum.

The left renal artery is much shorter and arises slightly more superior to the right main renal artery. The left renal artery courses more horizontally, posterior to the left renal vein to enter the renal hilum. Renal arteries are between cm in length and usually mm in diameter. Each renal artery gives off small branches in its proximal course, prior to dividing into dorsal and ventral rami.

These branches are very small and often not visible on imaging studies:. The dorsal and ventral rami divide into segmental branches within the renal hilum before entering the parenchyma: apical, anterior superior, anterior inferior middle , inferior and posterior segmental renal arteries. These then divide into lobar branches which successively branch into interlobar, arcuate, and interlobular arteries.

The afferent arterioles, which supply the glomeruli , originate from the interlobular arteries. Anatomy: Abdominopelvic.
