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.
Echocardiography/Ultrasound
- 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]
