Retrograde pyelography in 140 transplanted kidneys within 3 days of the operation showed a high frequency (29%) of pyelorenal backflow. Pyelotubular backflow, ordinarily a rare form of backflow, was seen in one-third of the patients whose transplants were removed within 60 days because of rejection, but in only 4% of the patients with surviving grafts. Pyelosinus backflow was found in 61% of the patients with signs of urinary obstruction, but in only 9% of the other patients. No relationship was found between pyelosinus backflow and graft rejection, or between pyelotubular backflow and urinary obstruction. Pyelotubular backflow may be an early radiographic sign of impending and serious rejection.
对140例移植肾在术后3天内行逆行肾盂造影检查，结果显示肾盂肾反流的发生率较高（29%）。肾盂肾小管反流通常是一种罕见的反流形式，在因排斥反应于60天内摘除移植肾的患者中，有三分之一出现这种情况，但在移植肾存活的患者中仅占4%。肾盂窦反流在有尿路梗阻体征的患者中占61%，而在其他患者中仅占9%。未发现肾盂窦反流与移植肾排斥反应之间、肾盂肾小管反流与尿路梗阻之间存在关联。肾盂肾小管反流可能是即将发生严重排斥反应的早期影像学征象。
