technetium-tc-99m-gluconate and Wilms-Tumor

In static scintigraphy with 99m Tc-pertechnetate of primary lesions of the retroperitoneal space in children 4 types of scintigraphic pictures were singled out for differential diagnosis of Wilms' tumors, avascular benign lesions of the retroperitoneal space and neurogenic retroperitoneal tumors. The sensitivity of diagnosis of Wilms' tumor was 92.6%, specificity 90.9%. The most objective and complete information on the kidney involvement in tumor process could be obtained in static scintigraphy with 99m Tc-pertechnetate combined with scintigraphy with 99m Tc-gluconate or 99m Tc-pyrophosphate. The sensitivity of diagnosis of secondary lesions of the lymph nodes of the retroperitoneal space was 76.8%.
