摘要
目的评价和比较B超、腹部平片、静脉肾盂造影、CT及MRI对髓质海绵肾的诊断价值。方法分析6例髓质海绵肾的影像学表现,其中6例行B超检查,5例行腹部平片、IVP和CT检查,1例行MRI检查。并进行文献复习。结果①髓质海绵肾以肾结石及血尿为主要临床表现,本组6例均有双肾多发性小结石及血尿;②腹部平片显示双肾区小斑点状高密度影;③静脉肾盂造影或CT显示肾锥体集合管扩张,充盈造影剂,呈小囊状,内可有小结石。结论髓质海绵肾影像学表现具有特征性,CT较IVP更敏感发现肾锥体内细小结石及早期的肾集合管扩张,是诊断本病的首选检查方法。
ObjectiveTo evaluate and compare the value of B-mode ultrasonography, plain abdomen films, intravenous urography,computed tomography and magnetic resonance imaging in the diagnosis of medullary sponge kidney (MSK). Methods6 patientswith MSK were included in this study. 6 cases were examined by B-mode ultrasonography, 5 cases by plain abdomen films, IVP andCT, one cases by MRI.Results① Renal stone and hematuria were the main clinical manifestations of MSK, which were found in6 cases. ② Multiple small calculus in renal medulla were showed in plain abdomen films. ③ When the patients were examined byintravenous urography and / or computed tomography, the dilated collecting ducts were felt with contrast medium, presenting astriped or small cystlike features. The dilated renal collecting ducts could contain small stones.ConclusionThe imaging manifes-tation of MSK is special. CT is more sensitive than IVP to reveal the calculus and the early dilatation of the renal collecting ducts. Itis the best way to diagnosis of MSK.
