Current indications to parathyroidectomy in CKD patients before and after renal transplantation

Secondary hyperparathyroidism (SHP) is one of the most challenging complications in the most advanced stages of end-stage renal disease. In the last decade, newly available medical tools have greatly increased the possibilities for controlling SHP. However, one of these tools, cinacalcet, has not yet been approved 
for its use in transplanted patients and the evidence for its safety in this clinical setting is still incomplete. For these reasons, many questions still remain open for the clinical nephrologist: when to consider a parathyroidectomy (PTX)  in a patient on a waiting list for kidney transplant  (KTx); when to recommend PTX after KTx; when could a regression of parathyroid hyperplasia 
be expected at any time after KTx. In the present paper, we will briefly deal with these questions in the light of an unusual clinical case.
