男34岁，车祸后20分钟出现休克，腹穿检查提示腹腔内大量积血，留置尿管尿液呈淡血色，无血块；急诊超声显示脾破裂，左肾被膜下血肿2cm×2cm。以下哪一种处理最为正确

A．积极抗休克同时急诊行脾切除和肾切除术

B．积极抗休克同时急诊行脾切除并修补肾脏，防止肾继续出血

C．积极抗休克同时急诊脾切除术，肾保守治疗

D．积极抗休克同时急诊肾切除术

E．积极抗休克同时急诊肾修补术

答案

参考答案：C

解析：该患者外伤后很快就出现休克，说明脾破裂非常严重，严重的脾破裂出血比较凶猛，况且往往难以修复，应该立即手术切除；该患者肾脏的损伤只表现为被膜下的血肿，属于肾挫伤病理类型，不必做特殊处理，一般的止血和预防感染抬疗就可以。
