Horseshoe kidney injuries are rare, and whether their management is similar to that of common renal injuries remains unclear. We present the case of a 41-year-old man who bruised his abdomen while riding a bicycle and experienced persistent abdominal pain. His vital signs were stable, but he had significant tenderness below the umbilicus. Contrast-enhanced abdominal computed tomography revealed a horseshoe kidney injury, urine leakage, and a urinoma. Conservative treatment was performed, but the urinoma continued to enlarge. Percutaneous drainage was performed on the seventh day in the hospital. The urinoma improved, and the patient was discharged on day 24. As in this case, horseshoe kidney injuries can easily lead to deep damage and associated complications compared to a normal kidney. Therefore, they are more likely to require surgical intervention. Although there are many methods of intervention, including endovascular treatment for bleeding, surgery, and drainage for urinoma, the management of horseshoe kidney injury requires consideration of the complex anatomy of the vascular and urogenital systems and identification of appropriate treatment modalities.
马蹄肾损伤较为罕见，其治疗方式是否与常见肾损伤相似尚不清楚。我们报告一例41岁男性病例，该患者骑自行车时腹部擦伤，随后持续腹痛。其生命体征稳定，但脐下有明显压痛。腹部增强计算机断层扫描显示马蹄肾损伤、尿液渗漏和尿瘤形成。我们进行了保守治疗，但尿瘤持续增大。患者住院第7天接受了经皮引流。尿瘤情况改善，患者于第24天出院。与正常肾脏相比，如本病例所示，马蹄肾损伤容易导致深部损伤及相关并发症。因此，它们更有可能需要手术干预。虽然有多种干预方法，包括针对出血的血管内治疗、手术以及针对尿瘤的引流，但马蹄肾损伤的治疗需要考虑血管和泌尿生殖系统的复杂解剖结构，并确定合适的治疗方式。
