Long-term follow-up of patients who underwent unilateral nephrectomy in childhood.


The long-term damaging potential of remnant nephron hyperperfusion was investigated in patients who had undergone unilateral nephrectomy in childhood. 27 such patients were examined after a mean of 23.3 years postnephrectomy. The average creatinine clearance was 83.9 +/- 16.5 ml/min/1.73 m2 or 74.3% of that in healthy controls with two kidneys; it was a value similar to that reported 3 to 6 months postnephrectomy in kidney donors. Age at the time of nephrectomy, duration of follow-up, or sex had no influence on the residual creatinine clearance. None of these patients had clinically important hypertension or proteinuria. Since so little evidence of kidney damage could be documented after such a long observation period, hyperperfusion would seem to be seldom of clinical importance in man unless other factors were present.
