To illucidate the diagnostic accuracy of ultrasound in the detection of renal stones we performed a blind comparative study of ultrasonography and i.v. urography. In 92 kidneys with 58 stones, 10 stones smaller than 6 mm were overlooked by ultrasound, whereas all stones 6 mm or larger were correctly detected. In one case of uric acid stone disease i.v. urography was inconclusive in determining the true nature of a renal pelvic filling defect, whereas ultrasound correctly diagnosed a stone. We conclude that ultrasonography has a place in diagnosis and control of renal stones.
为了阐明超声检查在肾结石检测中的诊断准确性，我们对超声检查和静脉肾盂造影进行了一项盲法对比研究。在92个肾脏中的58颗结石中，超声检查漏诊了10颗小于6毫米的结石，而所有6毫米及以上的结石均被正确检测到。在1例尿酸结石病中，静脉肾盂造影在确定肾盂充盈缺损的真正性质时未能得出明确结论，而超声检查正确诊断出结石。我们得出结论，超声检查在肾结石的诊断和监测中具有一定作用。
