Acute pyelonephritis on a single ectopic kidney revealing newly diagnosed diabetes: A case report

We report the case of a 62-year-old male presenting with polyuria-polydipsia syndrome and acute abdominal pain. The diagnosis of diabetic ketoacidosis complicated by acute pyelonephritis on a single ectopic kidney was confirmed through biological, radiological, and bacteriological assessments, with Escherichia coli identified as the causal pathogen. Insulin therapy and targeted antibiotic treatment led to a favorable outcome. This case highlights the importance of early diagnosis and prompt management of urinary tract infections in diabetic patients with renal anatomical anomalies.
