Abstract

A retrospective analysis was made in 189 cases with palpable abdominal mass in children including a comparison of ultrasonography and computed tomography. Of the 189 cases, 100(52.9%) were of urological cause and, of those, 89 were renal in origin Extraurinary origins included gastrointestinal and hepatobiliary tract, and ovary in order. Among 100 cases of urological cause, hydronephrosis (63 cases) was the most common cause. Remaining was Wilms' tumor (16 cases) and cystic renal disease (10 cases) respectively. Most cases of Wilms tumor (15/16) were presented beyond 1 year of age. The diagnostic accuracy of ultrasonography and computed tomography was 91.2% and 89.2% respectively in this series. In 22 cases of combined study of ultrasonography and computed tomography, no additional information has obtained from the computed tomography in terms of diagnosis and staging of the disease. It is concluded that ultrasonography accurate and useful diagnostic method for the evaluation of the disease and the staging of neoplastic disease in children.
