Quality of Life of Living Kidney Donors: A Single-Center Experience

Abstract

Renal transplantation improves the quality of life (QoL) of patients with end-stage renal disease. The preservation of QoL of living kidney donors is paramount. The aim of this study was to assess the QoL pre- and postdonation using Medical Outcome Survey Short Form-36 (SF-36) and to compare with a control group of potential donors who did not proceed with donation. Over a period of 28 years (1978 to 2006), 82 living donor renal transplantations were performed. Of the 78 eligible donors, 66 (85%) participated in the survey. The median postdonation period was 4.6 years (range, 3 months to 27 years). Thirty eight individuals were assessed in the control group. The postdonation SF-36 scores of the donors were not statistically significantly different from those of the control group except in one out of eight dimensions, which was physical role. However, in 44/66 (66%) donors, the postdonation scores were significantly lower compared to their predonation scores because of development of comorbidities such as musculoskeletal pain, migraine, myocardial infarction, diabetes, and peptic ulcers as the time progressed since kidney donation. The age, sex, time since donation, and relationship to recipient did not affect QoL. Eighty three percentage of the donors would have donated again if possible, and 90.9% wished to encourage living kidney donation. We conclude that the QoL of living kidney donors was not different from the healthy controls, although with the passage of time, there was some deterioration of QoL due to development of comorbidities.
