Opinion-based recommendation for the clinical follow-up of Wilms tumor survivors with a solitary functioning kidney

	No progressive renal injury	eGFR < 60 ml*min−1*1.73 m−2 and/or medication for proteinuria/hypertension
Blood pressure	Once yearly	2–4/year
Albuminuria	Once yearly	2–4/year
Serum creatinine/GFR	Every 5 years	2–4/year

24-h ambulatory blood pressure measurement is preferred in children and adults

Albuminuria may be estimated through the urinary albumin-to-creatinine ratio and should be determined in a first fresh morning sample (normal value <30 mg/g)

GFR can be estimated using the commonly used Schwartz formula (see Materials and methods)

Last ultrasound to be performed at 15–16 years of age

eGFR estimated glomerular filtration rate
