目的总结闭合性肾损伤的诊断与治疗。方法回顾性分析168例闭合性肾损伤患者的诊治资料。结果 168例均行尿液常规检查,血尿149例(88.7%);B超检查154例,阳性131例(85.1%);CT检查118例,阳性118例(100.0%),静脉尿路造影(IVU)检查28例,阳性19例(67.9%);保守治疗132例(78.6%),手术36例(21.4%),治愈165例,死亡3例。其中106例随访12~60个月,尿常规、肾功能、血压表现正常。结论闭合性肾损伤初步检查首选B超,CT评估肾损伤程度和分型最准确,如无严重腹腔脏器并发伤,CT检查和血流动力学指标改变表现严重时也有较大的保守治疗的可能性。 Objective To summarize the diagnosis and treatment of closed renal injury. Methods A retrospective analysis of 168 cases of renal failure patients with diagnosis and treatment of data. Results Of the 168 cases, urinalysis was performed routinely in 149 cases (88.7%); in the B ultrasound examination, 154 cases were positive (131 cases, 85.1%); CT examination was performed in 118 cases (118.0% IVU), 28 were positive and 19 were positive (67.9%). Conservative treatment was performed in 132 patients (78.6%) and surgery was performed in 36 patients (21.4%). 165 were cured and 3 died. 106 cases were followed up for 12 to 60 months, urinary routine, renal function, blood pressure showed normal. Conclusions The primary examination of closed renal injury preferentially chooses B-ultrasound and CT to evaluate the degree of renal injury and the most accurate classification. In the absence of serious abdominal organ injury, CT examination and hemodynamic changes are also more serious conservative treatment possibility.
