Complementary Role of Dual Isotope in Non-Bacteriuric Renal Infection - A Case Report

糖尿病患中，尿液細菌培養陰性之腎臟感染，雖不易診斷但卻非常重要，因為早期診斷以及早期治療，可以避免如腎臟膿瘍、腎因性高血壓、或甚至末期腎病等併發症。在此，我們報告一例患有菌血症的糖尿病患，其最初的尿液培養以及腎臟超音波皆呈現陰性。藉由雙核種核醫造影以及單光子斷層掃描顯示出一個位於左側腎臟上極的感染病灶，四天後電腦斷層掃描確立此病灶為急性局部細菌性腎炎。此一病例報告顯示67Ga併99mTc DMSA造影對於臨床上懷疑腎臟感染的病患，特別是尿液細菌培養陰性者有一定的貢獻。

To detect non-bacteriuric renal infection in a diabetic patient, though difficult but is very important because early diagnosis and early treatment can prevent later complications such as renal abscess, renal hypertension or even end stage renal disease. Herein, we presented a case of diabetic patient with septicemia whose urine culture and renal ultrasonography were negative initially. By using a combination of dual isotope images and single photon emission computed tomography technique, an infectious lesion in the upper pole of left kidiney was revealed, which was identified as acute focal bacterial nephritis by computed tomography four days later. This case report showed that 67Ga plus 99mTc dimercaptosuccinic acid images are useful in patients under clinical suspicion of renal infection, especially for those with negative urine analysis and/or urine culture initially.
