Purpose After peptide receptor radionuclide therapy (PRRT), renal toxicity may occur, particular in PRRTwith Y-labelled somatostatin analogues. Risk factors have been identified for increased probability of developing renal toxicity after PRRT, including hypertension, diabetes and age. We investigated the renal function over time, the incidence of nephrotoxicity and associated risk factors in p...
