Safety of renal biopsy bleeding prophylaxis with desmopressin.

Background: Percutaneous renal biopsy (PRB) is invasive, and bleeding-related complications are a concern. Desmopressin (DDAVP) is a selective type 2 vasopressin receptor-agonist also used for haemostasis.

Aim: To evaluate the side effects of intravenous (IV) weight-adjusted desmopressin preceding PRB.

Acute renal infarction: Clinical characteristics and prognostic factors.

Introduction: Acute renal infarction (ARI) is an uncommon disease, whose real incidence is probably higher than expected. It is associated with poor prognosis in a high percentage of cases.

Objectives: To describe the main clinical, biochemical and radiologic features and to determine which factors are associated with poor prognosis (death or permanent renal injury).
