Abstract: Renal abscess caused by fish bone ingestion is extremely rare and has not been reported in the literature. A male patient presented with a 1-week history of flank pain and a 2-day history of fever. Urinary ultrasound and CT scan showed an irregular hypodense lesion in the left kidney and blurred thickening of the descending colon wall. Three-dimensional CT reconstruction images revealed a needle-like foreign body, which perforated from the descending colonic lumen to the left kidney. The patient had accidentally eaten fish bone one week prior. On the basis of clinical data, the diagnosis of renal abscess caused by foreign body was suspected. Accordingly, laparotomy was performed, the abscess was drained, and the colon was repaired. The foreign body was confirmed to be fish bone. The postoperative condition of the patient was uneventful, and the patient remained well in the 3 months' follow-up without any further complaints.
