At basal a blood sample was drawn for glucose, creatinine and uric acid measurement and a 24 hour urine sample was collected for evaluation of daily uric acid excretion Radiolucent stones, which do not appear on KUB, may show up on ultrasound imaging studies. Other advantages of renal ultrasonography include its low cost and absence of radiation exposure. Ultrasound imaging is useful for detecting stones in situations where X-rays or CT scans are discouraged, such as in children or pregnant women Uric acid stones are radiolucent - invisible on a plain X-ray. Therefore, either a CT scan or an ultrasound is necessary to detect them. In addition, uric acid stones are one of the few stone types that may be dissolved Multiple stones may show flattened sides called faceted stones.
