Background: The aim of this study was to assess long-term residual kidney function after unilateral nephrectomy for non-syndromic Wilms tumor (NSWT). Methods: Of the patients who underwent one-sided NSWT at Tohoku University Hospital between 1977 and 2003, nine were followed up until age ≥18 years. For these nine patients, we retrospectively evaluated estimated glomerular filtration rate (eGFR) in childhood (3–10 years old), adolescence (11–17 years old) and adulthood (≥18 years). Results: Mean age at the last follow up was 23.0 years. Tumor classification was as follows: stage I tumor, n = 6; stage II tumor, n = 3; mixed-type nephroblastoma, n = 8; and congenital mesoblastic nephroma, n = 1. Mean eGFR was 101.3 ± 21.2 mL/min/1.73 m2 in childhood, 106.0 ± 32.1 mL/min/1.73 m2 in adolescence and 100.5 ± 20.7 mL/min/1.73 m2 in adulthood. Therefore, no significant change in eGFR was observed over the three life stages evaluated. Further, none of the patients met the diagnostic criteria for chronic kidney disease by early adulthood. Conclusions: eGFR after unilateral nephrectomy in patients with NSWT remained ≥60 mL/min/1.73 m2 during the transition from childhood to early adulthood, with no development of chronic kidney disease or end-stage kidney failure.
