Overview[edit | edit source]

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.

Echocardiography/Ultrasound[edit | edit source]

• 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]
