10	71 M	1st transplant Living related	Endstage renal failure due to diabetes mellitus type 2 and hypertension Here for 2-year protocol biopsy	27	128/61

The most common etiology for renal failure requiring transplantation was proliferative glomerulonephritis (4/10 patients). One patient (Patient #4) had had multiple transplants; the others still had their initial transplant. One patient was here for the first annual protocol biopsy; four patients for the 2-year protocol biopsy; one patient for a 4-year post-transplant biopsy; and, four patients for the 5-year protocol biopsy.
