肾缺如或发育不良的影像学诊断

Imaging Diagnosis of Renal Agenesis or Dysplasia

目的探讨肾缺如或发育不良在腹部及盆腔中的影像学特征。方法回顾性分析临床诊断的21例肾缺如或肾发育不良的患者,均行腹、盆腔CT平扫和(或)增强以及MRI扫描检查,分析其影像特征。结果21例患者中,男性占7例,女性占14例,7例男性患者均行CT全腹部平扫及增强扫描检查,其中4例考虑Zinner综合征,3例考虑肾发育不良合并患者输尿管下段囊肿、扩张。14例女性患者均行全腹部CT或MRI检查,3例仅行全腹部CT平扫检查,均考虑阴道斜隔综合征,8例女性患者行全腹部CT平扫及增强扫描检查,5例考虑肾缺如或发育不全合并子宫畸形,3例考虑肾低位并发育不良合并患侧输尿管异位,3例仅行MRI平扫检查,考虑肾缺如合并子宫和(或)阴道畸形。结论肾缺如或发育不良往往是影像学的一个征象,应全面观察腹部及盆腔区的情况,进行全面诊断,以免延误患者在其他方面的治疗。

Objective To investingate the imaging feature of the renal agenesis or dysplasia in abdomen and pelvic cavity.Methods The clinical diagnosis of 21 patients with renal agenesis or renal dysplasia was retrospectively analyzed.All patients underwent abdominal and pelvic CT plain scan and/or enhancement and MRI scan to analyze their image characteristics.Results Among the 21 patients,7 cases were male and 14 cases were female.All the 7 cases were examined by CT plain scan and enhanced scan.Among them,4 cases were considered Zinner syndrome and 3 cases were considered renal dysplasia complicated with lower ureteral cyst and dilatation.14 cases of female patients were also full abdominal CT or MRI,3 cases only whole abdominal CT scan,all consider oblique vaginal septum syndrome,8 cases of female patients with total abdominal CT scan and enhanced scan,5 cases were considered kidney agenesis or hypoplasia with uterine malformation,3 cases of considering kidney and dysplasia combined with low side ectopic ureter,3 cases of MRI scan line inspection,only consider the kidney deficiency such as combination of uterus and(or)vaginal deformity.Conclusion Renal agenesis or dysplasia is often a sign of imaging,should be a comprehensive observation of the abdominal and pelvic area,a comprehensive diagnosis,so as not to delay the patient in other aspects of treatment.
