Retained foreign bodies in the urinary system are commonly found in the urinary bladder but are a rare finding in the renal pelvis. Foreign objects can reach the renal pelvis via different pathways. The presence of a foreign body could be iatrogenic, or via direct penetration from the gastrointestinal tract. Presentation could mimic tumor, abscess, hematoma, or even renal stone. We report an unusual case of intrarenal foreign body presenting as renal stone. The patient presented with flank pain and symptoms suggestive of renal stone and a non-contrast CT scan was also indicative of stone, however on endoscopy a foreign body was identified and retrieved.
泌尿系统中的异物通常见于膀胱，但在肾盂中则较为罕见。异物可通过不同途径进入肾盂。异物的存在可能是医源性的，或经胃肠道直接侵入。其表现可能类似肿瘤、脓肿、血肿，甚至肾结石。我们报告一例罕见的肾内异物表现为肾结石的病例。该患者表现为胁腹疼痛及提示肾结石的症状，非增强CT扫描也显示有结石，然而在内镜检查时发现并取出了异物。
