Lutetium-177 prostate-specific membrane antigen (177Lu-PSMA) radioligand therapy is an option that is increasingly being used for treatment of metastatic castration-resistant prostate cancer. This delivers β-radiation to cells expressing PSMA and high accumulation of the radiopharmaceutical occurs in the kidneys. Here we report three cases of radiation nephropathy with severe chronic kidney disease induced by renal thrombotic microangiopathy following extensive treatment with 177Lu-PSMA radioligand therapy.
