Renal Cortical Atrophy

[JHoosier]

About a month ago I had an ultrasound on my gallbladder, but they also looked at surrounding organs. Everything came back fine except that my right kidney had cortical atrophy and increased echogenicity. Last week I had an ultrasound on both kidneys. Nothing came back about echogenicity, but it said that both kidneys had mild cortical atrophy. I had an ultrasound on my kidneys in 2017 because I was peeing frequently. So comparing the measurements from 2017, my kidneys have shrunk slightly.

2017

Right = 11.1x6.6x5.6 cm

Left = 11.6x5.7x6.1 cm

Dec, 2023

Right = 10.7x5.2x4.5

Left = 11.2x5.7x5.7

The most recent ultrasound was done by a trainee. He was being indirectly guided through the ultrasound by another person.

All of my blood and urine labs are completely normal. Nothing points to kidney issues.

I have to wait until February 14th to go to a specialist.

Anyone have any thoughts? Thanks!

The low side of normal is usually about 10cm in length, although some people's normal may be slightly lower. My bet is that you're fine, but only a nephrologist can tell you for sure.
