ABSTRACT

Emphysematous pyelonephritis is a urologic emergency characterized by an acute necrotizing, perinephric, and parenchymal infection caused by gas-forming uropathogens. It is considered a rare entity, with greater incidence in developing countries. Even though its pathogenesis is not fully understood, there are several well-identified factors involved in the spectrum of elements that result in the production of gas in the renal parenchyma. Various poor outcome factors associated with a high mortality rate have been described in different cohorts. The treatment of those patients can typically be divided into medical management, medical management plus endoscopic or percutaneous drainage, and emergency nephrectomy. Nevertheless, given that there are very few guidelines or treatment algorithms, there is no consensus on the management of patients with emphysematous pyelonephritis.
