Overview

Abdominal ultrasound may be helpful in the diagnosis of nephrolithiasis Findings on an ultrasound suggestive of/diagnostic of nephrolithiasis include: echogenic or hyperechogenic foci, acoustic shadowing, twinkle artefact on colour Doppler, colour comet-tail artefact , and increased resistive index which signifies acute obstruction.

  • Abdominal ultrasound may be helpful in the diagnosis of nephrolithiasis Findings on an ultrasound suggestive of/diagnostic of nephrolithiasis include:[2][3]
    • Echogenic or hyperechogenic foci
    • Acoustic shadowing
    • Twinkle artefact on colour Doppler
    • Colour comet-tail artefact
    • Increased resistive index which signifies acute obstruction
  • Abdominal ultrasound can help in avoiding the effects of radiation at first in about 70% cases.[2]
  • It can be used to watch for complications such as hydronephrosis.
  • Abdominal ultrasound can be used to look for stones in adjacent areas such as ureters where it can be 100% specific.[4]
