Normally, kidneys are about the size of a fist or 10 to 12 cm (about 5 inches). Kidney atrophy means that the kidney is smaller than normal. This can happen for two basic reasons.

What is kidney segmentation?

Kidney segmentation is an important step for computer-aided diagnosis or treatment in urology. In this paper, we present an automatic method based on multi-atlas image registration for kidney segmentation. The method mainly relies on a two-step framework to obtain coarse-to-fine segmentation results.

Why size of kidney is different?

The kidneys are just naturally unequal in size. The right kidney is commonly slightly bigger than the left, but some people are born with a larger left kidney than right. The kidneys are generally close to each other in size with the size difference generally less than one centimeter in length.

Which kidney is small in size?

The left kidney is usually a little larger than the right. The left kidney is usually also positioned slightly higher and closer to the heart than the right. One or both kidneys can atrophy, but it may be more likely to occur to the left kidney.

Does kidney size change with age?

Total kidney volume decreases by about 16 cm3 per decade, although most of the decline occurred after the age of 60 years old. Small kidney volume (below the sex-specific tenth percentile among healthy adults) associates with older age, even after adjustment for other risk factors.

What is normal size of female kidney?
