Is Hydronephrosis on Ultrasound Predictive of Ureterolithiasis in Patients with Renal Colic?

Abstract

Hydronephrosis on ultrasound did not accurately predict the presence or absence of a ureteral stone on computerized tomography in 25.0% of the patients in this study. Ultrasound is an important tool for evaluating hydronephrosis associated with renal colic but patients may benefit from other studies to confirm the presence or absence of ureteral stones.
