Ultrasonographic records of 239 patients with unexplained renal insufficiency were reviewed to determine the efficacy of renal ultrasonography as a screening examination. Ninety-five (40%) examinations were normal; 24 (10%) examinations showed no renal lesion, but some important incidental finding was discovered; 120 (50%) examinations showed a renal abnormality, including 24 (10%) that showed bilateral urinary tract obstruction. The discovery of bilateral urinary tract obstruction was of particular importance and, in the majority of cases (16/24), led to some type of definitive interventional procedure. Sonography in patients with renal insufficiency, whether normal or abnormal, provides useful information to the practicing physician with a potentially significant impact on the patient's clinical course.
回顾了239例不明原因肾功能不全患者的超声检查记录，以确定肾脏超声作为筛查检查的有效性。95例（40%）检查结果正常；24例（10%）检查未发现肾脏病变，但发现了一些重要的偶然发现；120例（50%）检查显示肾脏异常，其中24例（10%）显示双侧尿路梗阻。双侧尿路梗阻的发现尤为重要，在大多数病例（16/24）中，导致了某种类型的确定性介入治疗。肾功能不全患者的超声检查，无论结果正常与否，都能为执业医师提供有用信息，对患者的临床病程可能产生重大影响。
