Renal cyst infection is a frequent and serious complication of autosomal dominant polycystic kidney disease (ADPKD) that is often difficult to treat and can be fatal. While nephrectomy is the standard therapy for severe refractory renal cyst infection, it can be associated with severe adverse events. We experienced a case of repetitive renal cyst infection in a 58-year-old Japanese man with ADPKD on dialysis. He underwent renal transcatheter arterial embolization (TAE) four months after the last episodes of renal cyst infection, and his renal cyst infection has not recurred since renal TAE. This case suggested that renal TAE is effective for preventing repetitive renal cyst infection.
