A 69-year-old man presented with voiding difficulty, nocturia, and fever for 2 days. He had hypertension, diabetes mellitus, and benign prostate hyperplasia. On physical examination, there were no both costovertebral angle tenderness (CVAT). But urinalysis resusts show blood in urine and the extended-spectrum β-lactamase (ESBL)-producing Escherichia coli grow from the urine culture. He had undergone endoscopic mucosal resection (EMR) for about 3cm sized distal ascending-colon (A-colon) polyp that was later revealed to be intramucosal adenocarcinoma with free resection margins. Prophylactic hemoclips had been placed to prevent delayed bleeding after the procedure. Abdomen and pelvic computed tomography (CT) scan show right renal subcapsular hematoma with suspicious ureteritis and cystitis. Hemoclips on distal A-colon EMR site may induce traumatic right subcapsular hematoma because his distal A-colon is located near the right kidney. And the iatrogenic right renal subcapsular hematoma might make him susceptible to urinary tract infection. The patient had taken intravenous carbapenem antibiotics during hospitalization. The patient was discharged without fever and lower urinary tract symptoms. Such renal subcapsular hematoma following colon EMR is rare, and clipping on colon EMR site may be rare cause of retroperitoneal injury.
