[The pathway of vasopressin as a pharmacological target in nephrology: a narrative review].

ADH is a hormone secreted by neurohypophysis that plays different roles based on the target organ. At the renal level, this peptide is capable of causing electrolyte-free water absorption, thus playing a key role in the hydro-electrolytic balance. There are pathologies and disorders that jeopardize this balance and, in this field, ADH receptor inhibitors such as Vaptans could play a key role.

[Salvage of vascular access: a case study from the Columbus nephrology division, Rome, Italy].

Introduction: Arteriovenous fistula (AVF) salvage procedures play a crucial role in the care of the uremic patient, influencing quality of life and overall survival. In this study, we report on our centre's experience and analyse the outcomes, in terms of cumulative patency, of surgical salvage procedures on complicated AVFs.

Methods: Our study included patients who underwent surgical salvage procedures of their AVFs in our centre from 22/12/2009 to 29/12/2011.
