[Successful renal contraction therapy in polycystic kidney patient with renal transcatheter arterial embolization prior to ABO incompatible kidney transplantation].

28-year-old female received dialysis treatment due to chronic renal failure caused by polycystic kidney disease. Later, she underwent a laparoscopic splenectomy and ABO incompatible living kidney transplantation successfully following bilateral renal contraction therapy with renal transcatheter arterial embolization (renal TAE). A unilateral or bilateral native nephrectomy of a massively enlarged kidney performed at the time of renal transplantation is a common treatment in polycystic kidney patients scheduled for transplantation. On the other hand, when treated with renal TAE, such patients can avoid a laparotomy, which provides several advantages when undergoing peritoneal dialysis in the future or a laparoscopic splenectomy prior to ABO incompatible kidney transplantation. Furthermore, we consider that bilateral renal TAE is necessary for polycystic kidney patients prior to renal transplantation for a variety of reasons, including problems associated with contrast nephropathy if renal TAE for left kidney is remained after renal transplantation.
