Concerns regarding age-related comorbidities and perioperative risks have historically limited the use of older donors. This study aimed to compare perioperative outcomes between geriatric and young living kidney donors.

Materials and Method: Data from donors who underwent laparoscopic living donor nephrectomy at a single tertiary center between June 2018 and December 2024 were retrospectively reviewed. Donors were divided into two groups according to age: a Geriatric Group (≥60 years, n=29) and a Young Group (≥40 years, n=100). Donors aged 41-59 years were excluded by design to maximize between-group contrast. Demographic characteristics, comorbidities, perioperative morbidity parameters, length of hospital stay, and recipient outcomes were compared. Missing BMI data (32.5%) were handled by multiple imputation using Rubin"s rules.

Results: The mean age was 65.4±5.5 years in the geriatric group and 29.9±5.5 years in the young group (p<0.001). Hypertension was more prevalent among geriatric donors (31.0% vs. 1.0%; p<0.001), and surgical drains were used more frequently (58.6% vs. 23.0%; p=0.001). After multiple imputation, BMI was significantly higher in geriatric donors (28.4±5.1 vs. 25.4±5.6; p=0.029). Length of hospital stay was longer in the geriatric group (4.62±1.08 vs. 4.11±0.85 days; p=0.013). No significant differences were found in postoperative infection, bleeding, or creatinine levels. No graft loss or mortality occurred.

Conclusion: With careful selection, geriatric living kidney donors demonstrate acceptable perioperative outcomes comparable to younger donors. Chronological age alone should not be an exclusion criterion for living kidney donation. Keywords : Kidney Transplantation; Living Donor; Aged; Nephrectomy; Perioperative Care
