Wilms’ tumor being the most common malignant renal tumor in children with long term survival rates, proper staging and assessment of invasion is important. Our study is a retrospective study of 60 children diagnosed to have wilms’ tumor. out of 60 cases, 25 cases were stage II accounting for 41.7%, 36.7% were stage III, 11.7% were stage I and 10% were stage IV (NWTS staging). 45% of cases were found to have capsular / vascular invasion which is the most common route of spread of wilms’ tumor; the next being parenchymal invasion with 23%, followed by hilar/renal sinus invasion – 20 %
