Shunt nephritis is a rare complication in patients with ventricular atrial shunt (VAS) infection, used in the treatment of congenital or acquired hydrocephalus (1). Nevertheless, nowadays its incidence has decreased considerably, affecting only 0,7 – 2.25% of all the patients with ventricular atrial shunt (2,3). It is thought that shunt nephritis is due to the formation of immune complexes, which deposits on the glomerular base membrane in the kidney, because of a chronic bacteremia (5). A good prognosis of this pathology is achieved if an early antibiotic treatment is established, and the infected shunt is removed.
