Characteristics and survival of the kidney donor in Peru

Abstract

The kidney is an organ that is frequently transplanted, often coming from living donors, with few reports of survival in our environment. Objective: To identify the characteristics of kidney donors in a reference hospital of Lima, Peru. Material and Methods: Retrospective study in kidney donors of a hospital between 2015 and 2021. Performing a follow-up in the institutional registry system until December 2022. Glomerular filtration rate (GFR) (mL/min/1.73m2) was calculated based on the modified four-parameter MDRD-6 equation and the classification of chronic kidney disease into five stages. Results: Out of 305 renal transplants, 44.9% were in female patients and 15.5% in patients younger than 18 years old. The 34.4% of transplants corresponded to living donor (105 cases), who are between 25 to 65 years old (median 41, interquartile range 19), they was female (52.4%) and parents of the recipient 46.67%. Survival time from donation was 5.14 years (SD 2.33) with a range of 1 to 9 years, with GFR greater than 60% in 85.7% of patients, with no deaths identified. Conclusions: 45% of renal transplants between 2015-2021 in the hospital evaluated came from living donor, donors had a median age of 41 years, with direct blood relationship (mostly parents of the recipient). The average follow-up period was 5.14 years.
