Experiencing renal colic ~ 7 mo including 1 episode tht required ed visit. dr ordered us radiologist describes "a 1.3cm hyperechoic nodule" in kidney. does this mean it's not a stone? have history of ks.

Sono doesn't sound..: like stone. Needs further evaluation. see urologist, likely CT scan.

Kidney stone: It is unclear what this finding represents. If it is "non shadowing" meaning that the souls wave energy used to produce a sonogram image penetrates the lesion, it is often not a stone but a benign mass called an angiomyolipoma or AML. If it shadows, it is likely a stone. An X-ray (KUB) or a CT scan can help determine the nature of this finding. If it is a 1.2 cm stone it needs to be treated.
