It is unknown whether differences exist between body fat distribution and surgical outcomes in renal transplant recipients. The objective of this study was to identify whether the distance from external iliac vessels to skin correlates with findings in both surgical and long-term outcomes. METHODS: A retrospective chart review was completed of patients who underwent a renal transplant from 2016 to the end of 2019 at a single center. The Clavien-Dindo classification system was used to define post-operative complications. Descriptive statistics were analyzed, logistic regression determined predictors of differences between skin to vessel distance and other variables. RESULTS: Complete data were available for 96 patients undergoing renal transplant in 2016 to the end of 2019. 48% of patients (n=46) had 1 post-operative complication in the year following renal transplantation. Patients with complications had a significantly higher mean vessel to skin distance (138.8±4.5 mm vs. 123.8±4.1 mm; p=0.017) without a significant difference in BMI (28.3±0.8 kg/m2vs. 27.4±0.8 kg/m2; P=0.49). Median overall survival was longer in those without a post-operative complication (38 vs. 21.5 months; p=0.0295). There were no significant differences in warm ischemic time, sex, age, or other comorbidities. In the cohort with the greater skin to vessel distance, there were higher rates of delayed graft function (15 vs. 8 patients; p=0.0349) and longer lengths of stay (11.6±1.5 vs. 7.1±0.3; p=0.0021). Logistic regression for the skin to vessel distance and BMI revealed an area under the ROC curve of 0.641 (p=0.0175) and 0.541 (p=0.4860), respectively. CONCLUSIONS: These data suggest that a longer skin to external iliac vessel distance, as determined by cross sectional imaging, is more predictive (p=0.0175) of post-operative complications than BMI. Additionally, longer distances from skin to the external iliac vessels were associated with higher rates of delayed graft function, longer length of hospital stay and shorter median overall survival.
