本研究应用单光子发射型计算机断层(SPECT)对83例肾移植作了95次检测。本研究发现上尿路梗阻的 SPECT 图像分两种:普通型占大多数,特征是肾实质早期放射性稀疏区伴肾盂输尿管显像剂滞留;肾小管梗阻型少见,特征是肾皮质放射性滞留及髓质全程放射性稀疏而呈特征性“空心”肾。假性梗阻图像与普通上尿路梗阻的相同,利尿试验可区别之。排斥及急性肾小管坏死(ATN)时,放射性滞留在肾实质并伴其它功能损伤。
In this study, 95 single-photon emission computed tomography (SPECT) were performed in 83 renal transplant recipients. The study found that upper urinary tract obstruction SPECT images are divided into two types: the majority of common type, characterized by early renal parenchymal radioactive sparse with ureteropelvic imaging agent retention; renal tubular obstruction is rare, characterized by renal cords radioactive retention and medullary The whole radioactive sparse nature was characteristic “hollow ” kidney. Pseudo-obstruction images and the same general upper urinary tract obstruction, diuretic test can be distinguished. Exclusion and acute tubular necrosis (ATN), radioactive retention in the renal parenchyma with other functional damage.
