Ultrasonography in the Diagnosis of Wilms’ Tumor in Children

Abstract

Background: Ultrasound is a noninvasive imaging modality aids in diagnosis of abdominal complicacy without any potentially damage of paediatric patients. Wilms’ tumor is the second most common abdominal tumor in childhood and the most common primary pediatric renal malignancy.

Objective: The present study aims to evaluate the effectiveness of abdominal ultrasonography (USG) in the diagnosis of Wilms’ tumor and compare the results of USG with those of other methods.

Materials and methods: This descriptive, cross-sectional study was carried out in the Department of Paediatric Surgery of Mymensingh Medical College Hospital, Mymensingh, Bangladesh, from June 2015 to September 2016. A total of thirty patients with palpable abdominal masses in children were selected in this study. Among them, eighteen were male and twelve were female. Age ranged between 6 months and 12 years. Among thirty patients, twenty-five were operated and remaining five were inoperable and underwent enhanced abdominal CT scan.

Results: The results suggested that the predominance of male over female in the ratio of 3:2. This study confirms that Wilms’ tumor accounted for 30%. The sensitivity of ultrasonogram is 96.30% and the specificity is 60%. The positive predictive value is 92.86% and negative predictive value is 75% and the overall diagnostic accuracy of this series is 90.62%. In this study false positive rate of ultrasonogram diagnosis is 6.66% and false negative rate of ultrasonogram diagnosis is 3.33%.

Conclusion: Ultrasonography is a non-invasive, safe, inexpensive, and rapid diagnostic tool for determination of Wilms’ tumor. It may be the first line of investigation in the evaluation of Wilms’ tumor in paediatric surgical practice.
