End-stage renal disease among living-kidney donors: single-center experience.

OBJECTIVES: Renal transplant from living donors is widely accepted as a highly effective treatment for end-stage renal disease. Donors undergo a major operation with considerable perioperative risks of morbidity and mortality. Living with a single kidney also confers long-term risks. This study sought the incidence and causes of end-stage renal disease among living kidney donors. MATERIALS AND METHODS: This study included all donors who had reached end-stage renal disease among 2000 consecutive living-kidney donors. All operations and follow-up were performed in a single center. We studied the onset of renal disease, cause of end-stage renal disease, date of replacement therapy, and outcome. We also revised the donor's medical records related to their corresponding recipients. RESULTS: Of 2000 living donors, 8 developed end-stage renal disease; 6 were men (mean age, 30.87 ± 5.84 years. Renal failure occurred 5 to 27 years after donation. Renal transplant was done in 1 donor. Medical complications were proteinuria (6 patients), hypertension (7 patients), diabetes (3 patients), gout (3 patients), ischemic heart disease (5 patients), and hepatitis viral infection (4 patients). The causes of end-stage renal disease were diabetic nephropathy in 3 patients. Other possible causes included toxic nephropathy, chronic pyelonephritis, and preeclampsia. CONCLUSIONS: Living kidney donation is safe, and development of renal failure after donation is caused by the same causes as in the general population.
