Perioperative predictors for complications in patients with Xanthogranulomatous Pyelonephritis treated with nephrectomy.

Xanthogranulomatous pyelonephritis is an inflammatory disease characterized by chronic obstruction and infection. This pathology is a life-threatening condition when surgical treatment is carried out. We decided to retrospectively evaluate whether there were perioperative factors that predict complications in patients who undergo nephrectomy. We reviewed all nephrectomies done in the period of 2013-2018, in a tertiary referral Hospital with the histopathological diagnosis of Xanthogranulomatous Pyelonephritis. The presence of renal abscess at admission was observed as a risk factor associated with perioperative complications ( Anemia and the presence of abscess were important perioperative factors that predict perioperative complications.
