Impacto de la donación renal de vivo en la evolución de la función renal del donante

Resum

Background: Living donor kidney transplantation represents the best therapeutic option for patients with chronic terminal renal failure. However, nephrectomy bears certain short-as well as long-term risks for the living donor. In this study we want to evaluate the impact of donation on donor renal function.Materials and Methods: We retrospectively evaluated live kidneydonors in the period between 2010 and 2018 at the Ramón y Cajal University Hospital. A descriptive analysis of the sample was carried out and it was used in analysis of variance (ANOVA) to compare the age and the BMI with the clearance measured at the different moments of time. Likewise, the Kaplan-Meier survival curve was performed according to sex to see how many patients developed post-nephrectomy renal failure(CKD).Results: Of the 39 patients, one year after the nephrectomy, 34.4% had renal failure (<60ml / min / 1.73m2). No patient ended up on ESKD. The older patients had a greater deterioration of renal function. There is no greater deterioration of renal function in subjects with higher BMI.Conclusions: Age seems to be a risk factor for renal failure while BMI and sex do not seem to cause a greater risk in the deterioration of the glomerular filtration rate.
