目的探讨常规手术后患者短期卧床诱发输尿管结石的病因及诊治方法。方法对 3例术后卧床 7～ 10天诱发输尿管结石梗阻致急性肾功能衰竭患者进行分析。结果B超检查患者均有轻度肾积水 ,X线片未见阳性结石影。 3例中 2例经逆行插管治愈 ,1例经开放手术治愈。结论根据临床表现并结合B超检查均可明确诊断。确诊后应尽早进行逆行插管。 Objective To investigate the etiology and diagnosis and treatment of ureteral calculi induced by short-term bed rest after conventional surgery. Methods Three patients with acute renal failure induced by obstruction of ureteral calculi 7 to 10 days after operation were analyzed. Results B-ultrasound patients had mild hydronephrosis, X-ray film showed no positive shadow. Two of three cases were cured by retrograde intubation and one was cured by open surgery. Conclusions According to the clinical manifestations combined with B-ultrasound can confirm the diagnosis. Retrograde intubation should be done as soon as possible after diagnosis.
