[Compensatory hyperfunction in living kidney donors].
Renal transplantation using living donors still remains of interest, given the shortage of cadaveric donors. Using reference methods for measuring kidney function, we studied the adaptation to nephrectomy in 99 living donors. The glomerular filtration rate and renal plasma flow showed long lasting increase (by 40 and 33% respectively). Age and the glomerular filtration rate at surgery had a clear-cut effect on these changes. The spontaneous changes in protein intake further influence the value of post-nephrectomy glomerular filtration rate. The analysis of serial changes in serum creatinine or creatinine clearance would falsely have suggested a late increase in renal function. Microalbuminuria increased in few patients, pointing to the need for careful long term follow-up of such donors.
