Objective: In ischemia-reperfusion, Iloprost decreases neutrophil activation and aggregation besides inhibition of oxygen-free radical production. Pentoxifylline (Ptx) attenuates reperfusion-associated membrane injury and tissue edema, suppresses leukocyte adhesion and improves hindlimb blood flow during the reperfusion period. The primary hypothesis in this study was that Iloprost could present better protection than pentoxyfillin on renal ischemia-reperfusion in rabbit model.Materials and Methods: Forty rabbits were grouped into four. Iloprost was continuously infused starting half an hour before the reperfusion after 2 hours ischemia and during the 4 hours reperfusion period in Group 1 whereas the Group 2 was treated with pentoxyfillin. Group 3 was the control group which didn't receive any medication. Forth group was sham group. Renal tissues were histologically and biochemically evaluated.Results: The histologic scores were obtained according to presence of tubuler necrosis and atrophy, regenerative atypia, hydropic degeneration (Group 1 vs Group 3; p
