螺旋CT诊断髓质海绵肾

目的：为了提高对髓质海绵肾的螺旋CT诊断。方法：回顾性总结分析27例髓质海绵肾患者,包括临床表现、影像学检查,所有患者均采用西门子16排螺旋CT机扫描,全腹部CT平扫,必要时加增强扫描。结果：患者临床表现各异,病程10余天至1年。主要症状有腰胀、腰痛,1例有纳差、恶心、无尿、水肿（临床考虑有急性肾功能衰竭）,1例无临床症状,体检B超发现有双侧海绵肾。髓质海绵肾的CT表现为肾脏皮髓质交界处斑点或斑片状高密度影（结石或钙质沉着）。结论：螺旋CT对髓质海绵肾的诊断敏感性高、准确率高,可以定性诊断,而且还可以判断是否合并其他泌尿系结石及积水,图像直观,有利于临床进一步制定治疗方案。

Spiral CT diagnosis of medullary sponge kidney

Objective：To improve spiral CT diagnosis of medullary sponge kidney.Methods：Retrospectively analyzed 27 patients with medullary sponge kidney disease,included clinical manifestations,imaging examinations.All patients were siemensed 16 slice CT scan machine,full abdominal CT scan,if necessary,enhanced scan.Results：The clinical manifestations of patients were vary,the course was more than 10 days to 1 year.The main symptoms were lumbar swelling and back pain.1 patient had anorexia,nausea,no urine,edema（clinical considerations of acute renal failure）;1 patient had no clinical symptoms,ultrasound diagnosis found bilateral sponge kidney.Medullary sponge kidney CT showed renal corticomedullary junction spots or patchy high density（stones or calcinosis）.Conclusion：Spiral CT diagnosis of medullary sponge kidney has high sensitivity,high accuracy,and can be qualitative diagnosis.It also can determine whether combined with other urinary stones and water.it has visual images,and is conductive to the further development of clinical treatment.
