Classic (post diarrheal) the disease occurs frequently during warmer months. Objective: To assess the epidemiology, clinical presentation, laboratory studies, and important risk factor that affect the outcome. Patients and method: A prospective cross-sectional study included thirty-six consecutive patients with Hemolytic – uremic syndrome in this study who fulfil the criteria of the diagnosis of HUS (microangiopathic hemolytic anemia, acute renal failure and Thrombocytopenia.Patients who need dialysis referred to the renal unit AL- Yarmouk Teaching Hospital for peritoneal dialysis.
