Kidney failure in children with Wilms tumor: A study based on urine analysis and ultrasound

Renal insufficiency is one of the inevitable complications in patients with Wilms tumor (WT). The purpose of this study was to assess the renal function in children with WT at baseline and every 3 months to 2 years.In a descriptive-analytical study from 2018 to 2020, 48 children with WT were included in the study. Urine creatinine (UThe mean age of patients at follow-up was 7.3 years. There was no significant difference in mean UThis study showed that as WT progressed, the size of the kidneys increases without any renal insufficiency. Therefore, it seems that urinalysis of patients with WT along with sonography is necessary to determine renal insufficiency and the use of ultrasound alone to determine kidney insufficiency is not recommended.
