Objectives: The kidney is a vulnerable organ for acute lymphoblastic leukemia (ALL), by the disease, and various associated clinical pictures. This retrospective study aims to document renal ultrasound abnormalities in children with newly diagnosed ALL as well as to investigate the correlation between renal findings and clinical/laboratory/survival data. Methods: All children (age <18 years) with ALL were included in the study. An increase in size/nephromegaly (NM) or hyperechogenicity (HE) of the kidneys at first admission was accepted as a pathological renal abnormality. The clinical/laboratory findings, survival, and long-term renal functions were compared between patients with and without NM/HE. Results: The incidence of NM±HE was 12% in 163 patients. Enlargement of spleen, liver, or both and, hypercreatininemia was independently correlated with the presence of NM/HE. After the induction therapy, ultrasound findings were resolved in all patients, and NM/HE did not influence ALL prognosis. All survivors had normal renal functions in long term. Conclusion: The renal ultrasound abnormalities are not uncommon in children with leukemia at admission, without a negative impact on leukemia prognosis and on long-term renal functions.
