Clinical Outcomes in Living Donor Kidney Transplantation: A Single Center Experience in Latin America.

Background: In Latin America, few reports are available about the clinical outcomes of living donor kidney transplants (LDKT). We aim to evaluate the main clinical outcomes for LDKT patients in a single center's experience.

Methods: We retrospectively evaluated 530 LDKT patients who underwent transplantation from August 2008 to December 2020 at Colombiana de Trasplantes. Graft survival censored for death and patient survival were determined up to 5 years post-transplantation by the Kaplan-Meier method. Vascular and urinary complications, readmission, and reintervention rates were documented.

Results: A total of 530 LDKT patients were analyzed. Most of the recipients were men (56%). There were 123 patients (23.2%) with a preemptive transplant. Panel reactive antibody type I and II had higher immunologic risk (>20%) in 15.9% of the patients. The donor mean age was 37.8 ± 11.5 years. Most of the donors were women (52.6%) and related to the recipient (69.1%). Multivariate analysis identified panel reactive antibody type II (P = 0.003), female donor (P = 0.001), surgical reintervention at 30 days post-transplantation (P < .01), and delayed graft function (P < .01) as risk factors for graft loss. The graft survival death-censored rates were 93.7% and 89% at 1 and 5 years, respectively. Patient survival rates were 97.0% and 94.1% at 1 and 5 years after transplantation, respectively.

Conclusions: The long-term graft and patient survival rates in our center are comparable to previous reports from other leading centers. The clinical outcomes from a medium-sized center can be noteworthy, although not entirely new.
