Kidney transplant recipients are at increased risk of surgical site infections (SSIs) due to procedural complexity and immunosuppression. This retrospective single-centre study examines the influence of BMI on SSI risk and identifies common pathogens. A total of 230 renal transplant patients were included in this analysis 2017 and 2019. All patients received a cephalosporin for prophylaxis, and wound swabs were taken from those who developed SSIs. SSIs occurred in 45 patients (19.6%) and were not significantly associated with age, sex or donor type. The most common organisms were coagulase-negative staphylococci (26.7%), Staphylococcus epidermidis (24.4%), Enterococcus faecalis (22.2%) and Candida albicans (22.2%). SSIs were significantly linked to surgical revision (p < 0.001) and higher BMI (p = 0.027). A BMI ≥ 28.1 was associated with threefold higher odds of SSIs (OR = 3.0; p = 0.001). Each one-unit increase in BMI was associated with a 7.2% increase in the odds of SSI occurrence (OR = 1.072; p = 0.020). Staphylococcus (p = 0.019) and Enterococcus (p = 0.048) infections were more common in patients with BMI > 28.1. Therefore, SSIs are a frequent complication posttransplant and are strongly associated with high BMI. Standard antibiotic regimens may not cover all relevant pathogens in obese patients, underscoring the need for tailored prophylactic strategies.
