Clinical Trial Summary

Emphysematous pyelonephritis is a lifethreatening necrotizing infection of the kidney characterized by accumulation of gas in the renal parenchyma and within the surrounding tissues. The aim of the study is to report the outcome of the management of this condition at the investigators institution and to determine the microbiological characteristics, antibiotic resistance patterns, and to analyze factors predicting mortality and intensive care unit admission.


Description:

The investigators are planning to perform a retrospective study analyzing cases of emphysematous pyelonephritis from a single tertiary care institution in the north of Mexico in the period of 2011-2021. The diagnosis of emphysematous pyelonephritis is confirmed by computed tomography. Demographic, clinical, biochemical, therapeutic management, and outcomes will be collected. Variables will be analyzed to determine factors associated with admission to intensive care unit and mortality. Urine cultures will be analyzed and drug resistance profile will be determined using microdilution plate. Clinical and demographic characteristics will be analyzed using Chi square test for categorical variables, and T-test for numerical variables. Statistical significance is set at p<0.05. Statistical analysis will be performed with the SPSS software version 20.0.

Intervention

Procedure:
Nephrectomy
Different therapeutic options are described in literature for emphysematous pyelonephritis. In our center, medical treatment (no invasive procedure), ureteral stent (endourologic procedure), percutaneous drainage (minimally invasive procedure), and nephrectomy are the therapeutic options for this disease.
