Extended-spectrum beta-lactamase-producing Enterobacteriaceae urinary tract infections are challenging infections with increased mortality, morbidity, and failure of therapy. A 44-year-old Saudi male diabetic patient was seen at the ER of IMC Hospital with features of acute pyelonephritis: fever, burning urine, and left flank pain for three days. He was treated for cystitis at the Endocrine Clinic two weeks prior to his ER visit with nitrofurantoin and levofloxacin orally according to urine culture and sensitivity result. The patient was admitted, received IV meropenem, and continued to be febrile for three days. His urine and blood culture at ER grew the same ESBL-producing E. coli as in his urine culture from the Endocrine Clinic. His abdomen CT scan showed two left renal abscesses at the upper and middle poles. His temperature resolved on the fourth day of IV therapy. Intravenous meropenem was continued for 4 weeks after inserting PICC line and the patient was followed up by home healthcare. He was feeling better with occasional left flank pain and repeated abdomen CT scan showed complete resolution of both renal abscesses.

Diabetes mellitus (DM) is a common disease in Oman as in rest of Gulf Cooperation Council where metabolic syndrome is of high prevalence. DM is a foremost risk factor for urinary tract infections (UTIs). It is also linked to more complicated infections such as emphysematous pyelonephritis (EPN), emphysematous pyelitis (EP), renal/perirenal abscess, emphysematous cystitis, xanthogranulomatous pyelonephritis, and renal papillary necrosis. The diagnosis of these cases is frequently delayed because the clinical manifestations are generic and not different from the typical triad of upper UTI, which include fever, flank pain, and pyuria. A middle-aged female with DM and chronic kidney disease stage IV was admitted with recurrent UTI with extended-spectrum beta-lactamase-producing Escherichia coli. At presentation, she was afebrile, clinically stable, had no flank pain and there was no leukocytosis. Laboratory test for C- reactive protein done twice and was only mildly elevated at 7 and 11 mg/dL. A computed tomography scan of kidney-ureter-bladder (CT-KUB) was recommended and reported as "no KUB stone but small atrophic left kidney with dilatation of the pelvicalycial system and ureter and the presence of air in the collecting system suggestive of EP." Thus, commonly associated with DM, especially in females, debilitated immune-deficient individuals, and patients harboring obstructed urinary system with infective nidus. Air in the kidney is not always due to EPN. UTI with a gas-producing organism can ascend to the kidney in the presence of vesicoureteral reflux.

Acute pyelonephritis is a bacterial infection of the kidney and renal pelvis and should be suspected in patients with flank pain and laboratory evidence of urinary tract infection. Urine culture with antimicrobial susceptibility testing should be performed in all patients and used to direct therapy. Imaging, blood cultures, and measurement of serum inflammatory markers should not be performed in uncomplicated cases. Outpatient management is appropriate in patients who have uncomplicated disease and can tolerate oral therapy. Extended emergency department or observation unit stays are an appropriate option for patients who initially warrant intravenous therapy. Fluoroquinolones and trimethoprim/sulfamethoxazole are effective oral antibiotics in most cases, but increasing resistance makes empiric use problematic. When local resistance to a chosen oral antibiotic likely exceeds 10%, one dose of a long-acting broad-spectrum parenteral antibiotic should also be given while awaiting susceptibility data. Patients admitted to the hospital should receive parenteral antibiotic therapy, and those with sepsis or risk of infection with a multidrug-resistant organism should receive antibiotics with activity against extended-spectrum beta-lactamase-producing organisms. Most patients respond to appropriate management within 48 to 72 hours, and those who do not should be evaluated with imaging and repeat cultures while alternative diagnoses are considered. In cases of concurrent urinary tract obstruction, referral for urgent decompression should be pursued. Pregnant patients with pyelonephritis are at significantly elevated risk of severe complications and should be admitted and treated initially with parenteral therapy.
