Renal complications are rare in patients with Prader-Willi syndrome (PWS). We herein experienced a 31-year-old woman with PWS, in whom a renal biopsy showed IgA nephropathy and severe intimal thickening of the interlobular arteries. The patient was admitted to our hospital due to proteinuria and microscopic hematuria after an upper respiratory infection. The occurrence of cardiovascular events has been reported as a cause of death in obese PWS patients. Because chronic kidney disease is generally a risk factor for cardiovascular disease, early detection checkups are essential in obese PWS patients to monitor the possible development of cardiovascular disease.
