We studied 98 kidneys in 55 patients with bone scintiscans and renal sonography. Among the 29 kidneys in which hydronephrosis was suspected on bone scintiscans only 12 were truly hydronephrotic by renal ultrasound. In the other 17 cases extrarenal pelves, postural stasis, early urinary tract obstruction or renal parenchymal disease may have contributed to the discrepant findings. By ultrasound criteria there were no false negative readings for hydronephrosis on scintiscan. While it is safe to interpret absence of hydronephrosis caution should be used in diagnosing hydronephrosis, since less than half of the cases actually will have the disease when suspected on a bone scintiscan.
我们对55例患者的98个肾脏进行了骨闪烁扫描和肾脏超声检查。在29个仅通过骨闪烁扫描怀疑有肾积水的肾脏中，经肾脏超声检查仅有12个确实存在肾积水。在其他17例中，肾外肾盂、体位性淤滞、早期尿路梗阻或肾实质疾病可能导致了检查结果的差异。根据超声标准，闪烁扫描对肾积水没有假阴性结果。虽然可以放心地解读为不存在肾积水，但在诊断肾积水时应谨慎，因为在骨闪烁扫描怀疑有肾积水的病例中，实际患有该病的病例不到一半。
