Two boys investigated for gross hematuria and left loin pain were found on ultrasound (US) to have left renal vein (LRV) entrapment associated with isomorphic urinary red blood cells, but normal renal venograms. Over the next 18 months ten children with gross hematuria were investigated and two more boys were discovered with the LRV entrapment syndrome, i.e., isomorphic red cells and a diagnostic US. Venography has a low yield in detecting renal venous compression, and since urinary red cell morphology may localize the origin of renal bleeding, we strongly recommend simple procedures, i.e., phase microscopy and renal US to evaluate all cases of hematuria before employing invasive or radiation dependent investigations. Since there is a range of LRV compression and associated dilatation in asymptomatic patients, strict criteria must be applied to diagnose renal vein entrapment.
两名因肉眼血尿和左腰部疼痛接受检查的男孩，经超声（US）检查发现左肾静脉（LRV）受压，伴有均一性尿红细胞，但肾静脉造影正常。在接下来的18个月里，对10名肉眼血尿患儿进行了检查，又发现了两名患有LRV压迫综合征的男孩，即均一性红细胞和诊断性超声检查结果。静脉造影在检测肾静脉受压方面的阳性率较低，而且由于尿红细胞形态可能有助于定位肾出血的来源，我们强烈建议在采用侵入性或依赖辐射的检查之前，通过简单的程序，即相差显微镜检查和肾脏超声，对所有血尿病例进行评估。由于无症状患者存在一系列的LRV受压和相关扩张情况，因此必须应用严格的标准来诊断肾静脉受压。
