Abstract:
PURPOSE: To evaluate the pathology of prospective kidney donors and assess the clinical outcomes of the renal allografts. METHODS: We reviewed the records of 12 prospective kidney donors who underwent kidney biopsy. The indications of kidney biopsy were asymptomatic microscopic hematuria (n=88, 66.7%), decreased glomerular filtration rate (GFR, n=22, 16.7%), mild proteinuria (n=11, 8.3%), history of gross hematuria (n=11, 8.3%). RESULTS: Kidney biopsy in 8 prospective donors with asymptomatic microscopic hematuria showed: 5 (62.5%) thin basement membrane disease (TBMD); 1 IgA nephropathy; 1 Alport's syndrome; 1 mild mesangial widening. Two prospective donors with decreased GFR showed IgA nephropathy and tubulointerstitial lesion. The one with mild proteinuria showed arterionephrosclerosis and the one with a history of gross hematuria showed tubulointerstitial lesion. 4 (33.3%) of the 12 who underwent kidney biopsy were accepted as kidney donors.; 3 donors with TBMD and the donor with mild mesangial widening, who all had microscopic hematuria. Among the 4 donations, there was 1 graft failure and 3 allografts (1 mild mesangial widening, 2 TBMD) have maintained graft function at latest follow up. CONCLUSION: The most common cause of asymptomatic microscopic hematuria in prospective kidney donors was TBMD. Long-term follow up is needed to assess the clinical outcomes of these allografts.
