A prospective sonographic analysis of kidneys in 136 adults without clinical or radiologic evidence of renal disease revealed 22 cases of large columns of Bertin. Most were located in the middle third of the kidney, more frequently on the left side. They were bilateral in 18%. Water bath sonograms of normal cadaver kidneys and subsequent anatomic correlation revealed hypertrophied columns and confirmed the sonographic findings seen in vivo. The following are characteristic of a hypertrophied column of Bertin: It is a projection of cortex into the renal sinus (and therefore is isoechogenic with it). The sinus may engulf it in a clawlike fashion. The renal contour is smooth. Sonography is characteristic and obviates further investigation.
对136例无肾脏疾病临床或放射学证据的成年人进行肾脏前瞻性超声分析，发现22例存在巨大的贝尔廷柱。大多数位于肾脏的中三分之一，左侧更为常见。18%为双侧性。正常尸体肾脏的水浴超声图像及随后的解剖学对照显示为柱状肥大，并证实了活体中的超声检查结果。贝尔廷柱肥大具有以下特征：它是皮质向肾窦的突出（因此与肾窦等回声）。肾窦可能呈爪状包绕它。肾脏轮廓光滑。超声检查具有特征性，无需进一步检查。
