Clinical outcomes of patients with emphysematous pyelonephritis according to type of treatment and classification of severity by Huang-Tseng.

BACKGROUND

Emphysematous pyelonephritis (EP) is an acute, necrotizing infection of the renal parenchyma and surrounding tissues, characterized by the presence of gas in the renal parenchyma and adjacent structures.

OBJECTIVE

To analyze the outcomes of patients with EP, treated at the General Hospital of Mexico.

MATERIAL AND

METHODS

An observational, analytical study was carried out, between January 2018 and December 2023. Clinical data, urine cultures and tomographic findings (severity classification by Huang-Tseng) were collected.

RESULTS

51 clinical records were included, 64.7% women, and average age 52 years. 70% lived with diabetes type 2 and 60% had uro-renal lithiasis, about 30% had severe EP. 80% of cases were resolved with treatment based on antibiotics and drainage by interventional radiology. There was an average of 10 days of hospitalization and fatality of 5.9%; the severity of the acute kidney injury showed an association with mortality (p ≤ 0.05).

CONCLUSIONS

The combined use of antibiotics with drainage of the abscess through interventional radiology was associated with a decrease in morbidity and mortality in these cases.
