Introduction: 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. Methods: We reviewed all nephrectomies done in the period of 2013–2018, in a tertiary referral Hospital with the histopathological diagnosis of Xanthogranulomatous Pyelonephritis. Results: The presence of renal abscess at admission was observed as a risk factor associated with perioperative complications (p = 0.002), presence of abscess was observed in 47.4% of subjects without complications compared to 89.3% of the perioperative complication group. Higher rates of blood transfusion requirement were observed in the perioperative complication group, 89.3% compared to 68.4% (p = 0.029), furthermore, perioperative bleeding was slightly greater in the complication group compared to its counterpart, 700 mL, and 600 mL, respectively (p = 0.01). Conclusions: Anemia and the presence of abscess were important perioperative factors that predict perioperative complications.
