The authors review the case of their young patient, who underwent a lung transplantation in Vienna because of an end stage idiopathic pulmonary fibrosis. During the prolonged postoperative phase renal failure full of complications developed, which necessitated haemodialysis. As the pulmonological rehabilitation was complete, but the regular dialyses considerably raised the risk of opportunistic infections, and also significantly reduced the quality of life of the patient, renal transplantation was performed in Debrecen four years after the lung transplantation. This is the first lung transplanted patient in Hungary who also underwent renal transplantation. Now, more than two years after the renal transplantation the patient lives a compensated, rehabilitated life, the respiratory function values have improved and the renal function values are also acceptable. The number of transplanted patients has significantly increased in recent years worldwide, and also in Hungary. However, due to immunosuppressive medications, calcineurin inhibitors mainly, numerous complications must be reckoned with. An outstanding one among them is the secondary renal failure which may occur both in acute and chronic form and may even necessitate renal transplantation. Renal transplantation is an excellent treatment option for end stage renal failure patients, who had received another organ transplant earlier. Kidney transplantation improves quality of life and increases expected survival, too.
