Renal transplant is an important treatment option for end-stage renal disease. A successful kidney transplant improves the quality of life and reduces the mortality risk compared with maintenance dialysis in patients with end-stage renal disease. Several immunologic and nonimmunologic factors are responsible for graft outcomes in renal transplant patients. Our study was performed to evaluate the role of smoking on postoperative pulmonary complications and graft outcomes in renal transplant patients. Our study retrospectively analyzed 1740 patients who had renal transplants between 1987 and 2014 at Baskent University. Patients with smoking data were included in the study. Patient demographic, smoking status, comorbid diseases, postoperative pulmonary complications, graft outcomes, and clinical features were recorded. The relation between postoperative pulmonary complications and risk factors was investigated. Our study included 131 adult renal transplant recipients who had smoking data. The incidence of postoperative pulmonary complications was 16% (21 patients) in the first month after surgery. Smoking history was found in 52 patients (39.7%). There was a statistically significant relationship between the presence of atelectasis and smoking history (P = .004). A positive and statistically significant correlation was detected between atelectasis and pack-years smoking (r = 0.424; P = .001). We evaluated graft rejection within 1 month after transplant regardless of being acute cellular or humoral rejection. The relation between smoking history and graft rejection within 1 month after transplant was significant (P = .011). Renal transplant patients who are smokers have an increased risk for early postoperative pulmonary complications. Furthermore, cigarette smoking contributes to allograft loss in renal transplant patients. Smoking cessation before surgery can reduce the risk of early postoperative complications.
