“…Imaging techniques are considered very helpful in the diagnosis, and routine ultrasound is the preferred choice due to its non-invasiveness. 7 , 9 In this study, the lesions were found by routine ultrasound during routine physical examination in 254 patients.…”

BackgroundThere are a variety of space-occupying lesions of the kidney, and the benign lesions may be difficult to differentiate from the malignant ones. Therefore, an accurate judgment of the benign and malignant nature of the space-occupying lesions of the kidney is of high importance for the treatment and prognosis of these patients.ObjectiveTo evaluate the diagnostic value of contrast-enhanced ultrasound (CEUS) combined with contrast-enhanced computed tomography (CECT) in space-occupying lesions of the kidney.Data and methodsThree hundred and sixty-seven patients with space-occupying lesions of the kidney (378 lesions) were examined by CEUS and CECT, respectively, then, a combined diagnosis was made after the combination of CEUS and CECT by a multidisciplinary team. The diagnoses from the three methods were compared. The pathological results were taken as the gold standard. The sensitivity, specificity, positive and negative predictive values and area under the receiver operating characteristic (ROC) curve were calculated for the three methods. Thus, the diagnostic value of the three methods was assessed.ResultsOf the 378 lesions examined, there were 301 malignant lesions and 77 benign lesions. The combined examination revealed 303 malignant lesions, with 9 benign lesions mistakenly diagnosed as malignant ones; thus, the misdiagnosis rate was 11.7%. By using the combined examination, 75 benign lesions were diagnosed, with the missed diagnosis of 7 malignant lesions, so the missed diagnosis rate was 2.3%. The sensitivity, specificity, positive and negative predictive values and area under the ROC curve with the combined examination of CEUS and CECT were 97.67% (0.950–0.989), 88.31% (0.785–0.942), 97.03% (0.942–0.985), 90.67% (0.811–0.958) and 0.930 (0.887–0.973), respectively. As compared with either CEUS or CECT alone, the difference in these indicators was of statistical significance (P<0.05). The combined examination greatly improved the sensitivity, specificity and accuracy of the diagnosis of the space-occupying lesions of the kidney.ConclusionCEUS and CECT each have advantages and disadvantages in the diagnosis of the space-occupying lesions of the kidney. The two techniques can be used in combination to compensate for the respective defects. More salient benefits can be reaped from the combined examination than from either technique used alone.

Ultrasound is an essential and often initial visualization diagnostic procedure in all algorithms for urgent care of acute abdominal conditions. Ultrasound is a fast, accessible, non-invasive diagnostic examination method that does not involve ionizing radiation and can be repeated. It is vital in detecting free fluid in the abdominal cavity, acute pathological conditions of parenchymal and hollow organs, and assessing volemic status. Ultrasound efficiently and accurately diagnoses acute pathological conditions of the hepatobiliary and urogenital system. It certainly makes a significant contribution to the definitive diagnosis of pathological conditions of the gastrointestinal and vascular systems and can help detect pneumoperitoneum as an indication for urgent surgical treatment.
