Abstract
Twenty-nine patients who had had unilateral nephrectomy for Wilms' tumour in one hospital were known to have survived more than 12 years. Sixteen agreed to attend for clinical review, of whom 14 had estimation of serum creatinine, 24-h urine protein excretion and endogenous creatinine clearance. The follow-up period was 13–26 years (median 17 years). All but one had had radiotherapy and all had chemotherapy (actinomycin D, 16; vincristine, 5). Some degree of kyphoscoliosis was present in all except the patient who did not receive radiotherapy. Four patients had diastolic blood pressure 90 mmHg or greater. Two patients had mild proteinuria (392, 361 mg/day). Serum creatinine ranged from 53 to 125 μmol/l and endogenous creatinine clearance ranged from 39 to 173 ml/min (median 81, mean 89). Of the 7 patients who were 20–26 years postnephrectomy, 2 were hypertensive and 1 had elevated urinary protein excretion. We conclude that the long-term prognosis of unilateral nephrectomy in childhood is good.
