Acute renal failure after exercise with frank pain and patchy renal vasoconstriction is a clinical syndrome that occurs in young, previously healthy persons. The authors describe a 24-year-old man who had this syndrome. CT scan showed wedge-shaped contrast enhancement of both kidneys, which suggested patchy renal vasoconstriction. Tc-99m MDP imaging revealed diffuse increased uptake of both kidneys. After renal function was improved, Tc-99m MDP imaging showed normal uptake of both kidneys. Acute renal failure due to acute tubular necrosis was confirmed by renal biopsy. The authors conclude that Tc-99m MDP may be useful in evaluation of acute renal failure after exercise with flank pain and patchy renal vasoconstriction due to acute tubular necrosis.
运动后出现明显疼痛和散在性肾血管收缩的急性肾衰竭是一种发生在年轻、既往健康人群中的临床综合征。作者描述了一名患有此综合征的24岁男性。CT扫描显示双肾楔形强化，提示散在性肾血管收缩。锝-99m亚甲基二膦酸盐（Tc-99m MDP）显像显示双肾摄取弥漫性增加。肾功能改善后，Tc-99m MDP显像显示双肾摄取正常。肾活检证实为急性肾小管坏死所致的急性肾衰竭。作者得出结论，Tc-99m MDP可能有助于评估运动后因急性肾小管坏死导致的伴有胁腹痛和散在性肾血管收缩的急性肾衰竭。
