A case of hematuria and vomiting in the emergency room: Never forget the emphysematous pyelonephritis

Abstract

We describe the case of a 68-year-old man with a known history of hypertension and diabetes mellitus presented to our Emergency Department, complaining of hematuria and vomiting in the last 12 hours, stypsis and urinary incontinence in the last week, and worsening hyporexia in the last 6 months. Bedside ultrasound documented a slight right pleural effusion with B lines in the middle and basal right field, gastrectasis, dilated fluid-filled bowel loops, potential signs of gas in the upper right quadrant, grade 3 bilateral hydronephrosis, and bladder globe. Abdominal CT scan confirmed the bilateral hydroureteronephrosis and showed the right kidney with Emphysematous Pyelonephritis (EPN) with extension into the perinephric and muscular planes for 24 cm, and initial EPN in the left kidney. A RT-PCR nasopharyngeal swab for SARS CoV-2 was negative. A diagnosis of ileum paretic, acute renal failure and urosepsis due to EPN was made.
