Objectives: To determine predisposing factors in perinephric abscesses and to find events associated with unfavourable outcome. Methods: We carried out a clinical, descriptive, retrospective and cross-sectional study, including 23 patients diagnosed of perinephric abscess admitted to our hospital. Results: In patients with perinephric abscess, cli-nical charts included diabetes mellitus in 65.2%, history of nephrolithiasis in 43.47% and history of urological surgery in 17.38%. On hospital admission, haemoglobin greater than 10.5 g/dL and white blood cell count lower than 15 x 10³ / µL were associated with nephrectomy, and platelet count lower than 140 x 10³ / µL with septic shock. General mortality was 8.69%, and 78.3% if patient required nephrectomy. Patients who died had fever, anaemia, white blood cell count greater than 16 x 10³ / µL, platelet count lower than 130 x 10³ / µL, and hyponatremia of 125 mEq/L or lower at hospital admittance, and all of them had septic shock and required nephrectomy. Conclusions: In our series, a higher percentage of patients had diabetes mellitus and/or nephrolithiasis. Haemoglobin level and white blood cells count were associated with loss of the renal unit, thrombocytopenia was associated with septic shock and hyponatremia with mortality.
