影像学检查阴性的输尿管结石致急性肾功能衰竭的急诊处理

目的 探讨影像学检查阴性的输尿管结石致急性肾功能衰竭的急诊处理方法。方法 回顾分析影像学检查阴性的输尿管结石致急性肾功能衰竭的患者36例，采用输尿管镜检查确诊，并行输尿管镜直视下取石、气压弹道碎石，术后均留置双J管。结果 36例患者均在入院当天解除梗阻。尿量增加，尿毒症的症状消失，BUN、Cr恢复正常。结论 应用输尿管镜诊疗影像学检查阴性的输尿管结石致急性肾功能衰竭，具有迅速明确诊断、疗效可靠、安全性高、创伤小的优点，并能同时处理双侧输尿管结石，是首选的诊疗方法。

Emergency treatment for acute renal failure caused by negative imaging ureterolith

Objective To explore emergency treatment methods for acute renal failure caused by negative imaging ureterolith. Methods There were 36 cases of acute renal failure caused by negative imaging ureterolith, which were finally diagnosed by ureteroscope examination. The negative imaging ureterolith were broken by air pressure ballistic curve shock wave, and taken out of ureter by ureteroscope. All cases were put double- J in ureter. Results Thirty- six cases were got success relieves of ureter obstruction in 24 hours. The urine volume of them were increased, symptoms of urinemia were disappeared, BUN and creatinine were normal after operations. Conclusions The treatment and diagnosis methods by ureteroscope for acute renal failure caused by negative imaging ureterolith are quick and safety, which can treat both side ureterolith at the same time and get reliable and safe effect with less trauma. It should be the first choice to treat acute renal failure caused by negative imaging ureterolith.
