Message for the clinic: what is the ‘take-home’ message for the clinician?
We determined that microscopic hematuria was associated with stone size and hydronephrosis severity. If a patient with suspected ureteral stone disease does not have microscopic hematuria, we consider that non-contrast CT imaging is necessary for diagnosis and treatment, since the size of the stone may be larger and the degree of hydronephrosis may be more severe.
