Abstract:
Introduction:
A severe kidney infection associated to gas production in the renal parenchyma and/or collecting system is known as emphysematous pyelonephritis. The aim of this study was to assess the effects of urolithiasis on the severity of emphysematous pyelonephritis in a modern cohort of patients and their outcomes.
Methods:
From 2023 to 2024, a study was conducted for the word “emphysematous pyelonephritis” in all imaging reports at Bharati Hospital and Research Centre. Patients were considered for inclusion if they had computed tomography showing gas in the renal parenchyma or collecting system, no recent urologic instrumentation, and clinical signs of infection. The laboratory and clinical characteristics were taken from patient medical records.
Results:
Twenty cases in all were identified. Sixty percent of the patients had gas that was confined to the collecting system. Gas was present in the renal parenchyma in four patients (20%) and in the perirenal tissues in four patients (20%). Twelve individuals, or 60% of the total, also had concurrent urolithiasis. DJ stenting, either bilateral or unilateral, was done for every patient. None of the patients needed a nephrectomy right away. There were no deaths. Emphysematous pyelonephritis with urolithiasis was less severe than non-urolithiasis patients.
Conclusions:
Most of the study’s patients had gas confined to the collecting system, and DJ stentning proved to be an effective treatment for them. No patients needed a nephrectomy on emergency basis. Patients with urolithiasis had less severe emphysematous pyelonephritis than those without urolithiasis.
