Ultrasound diagnosis of horseshoe kidneys depends on the demonstration of an isthmus or band of renal tissue across the midline of abdomen connecting the lower poles of the kidneys. In a number of cases this band of renal tissue may evade ultrasonic detection. In a series of 11 patients with horseshoe kidneys, sonographic detection of renal isthmus was achieved in seven patients, but in all 11 cases there was demonstrable alteration of renal outlines. Instead of normal reniform shape, the kidneys appeared "inverted pyriform" or "inverted triangular". Detection of such an altered renal outline should raise suspicion of horseshoe kidney.
马蹄肾的超声诊断依赖于显示一条肾组织峡部或带，其穿过腹部中线连接肾下极。在许多病例中，这条肾组织带可能逃避超声检测。在一组11例马蹄肾患者中，7例实现了肾峡部的超声检测，但在所有11例中均有可证实的肾轮廓改变。肾脏不是正常的肾形，而是呈“倒梨形”或“倒三角形”。检测到这种改变的肾轮廓应引起对马蹄肾的怀疑。
