肾柱肥大在影像学检查中，尤其一般超声诊断，常被误诊为肾内占位病变，使得这一原本无危害的解剖变异具有一定的临床意义。本文总结了３０例肾柱肥大的超声检查工作，部分患者备有ＩＶＵ、ＣＴ等资料，我们对肾柱肥大的声像图特征加以报道，并对其近年来的学术进展作了扼要介绍。我们认为超声是一种简单可行的检查方法，它可以为肾柱肥大提供明确的诊断依据。 Renal enlargement in imaging examination, especially in general ultrasonic diagnosis, often misdiagnosed as intrahepatic space-occupying lesions, making this originally non-hazardous anatomic variation has some clinical significance. This article summarizes the 30 cases of renal hypertrophy ultrasound examination work, some patients with IVU, CT and other data, we report on the characteristics of renal hypertrophy sonography are reported, and its academic progress in recent years made a brief introduction. We believe that ultrasound is a simple and feasible method of examination, which can provide a clear basis for the diagnosis of renal hypertrophy.
