Can color ultrasound detect kidney stones and kidney tumors?

Color ultrasound usually refers to color ultrasound examination. Color ultrasound examination can generally detect kidney stones and kidney tumors.

Stones will block the transmission of ultrasound, so patients with kidney stones will show high echo when doing color ultrasound examination. Kidney tumors will also block the transmission of ultrasound, but depending on the texture of the tumor, it may be reflected as high echo or low echo, and there will be obvious differences from normal tissues. Therefore, color ultrasound examination can generally detect kidney stones and kidney tumors.

Patients should drink plenty of water before examination and keep bladder filled so that doctors can observe the lesion site.
