PLEURAL EMPYEMA AND PERINEPHRITIC INFECTI ON ASSOCIATION - A PROPOS OF 4 CASES

Empyema of renal origin is very rare (3% in our series). We discuss 4 cases of empyemas associated to perirenal infection. Two of them were diabetic and all of them have renal lithiasis. They made their debut t hrough pleural effusions, isolating Escherichia coli in all of them. T reatment was antibiotics and drainage in both foci, three of them evol ved to healing and one of them died being the abdominal foci without d rainage. This association must be suspected when no clear etiology of the empyema is present in patients with history of renal lithiasis and diabetes
