摘要
目的：探讨99mTc-二乙三氨五醋酸（DTPA）肾动态显像在先天性肾发育不良诊断中的临床应用价值。方法：12例先天性肾发育不良患者均行99mTc-DTPA肾动态显像和腹部超声检查，其中11例行腹部增强CT扫描，8例行静脉肾盂造影（IVP）。结果：99mTc-DTPA肾动态显像发现肾发育不良7例（58.3％，7/12），探测灵敏度与增强CT相当（χ2＝1.5，P>0.05），优于B超（χ2＝4.4，P<0.05）；8例行IVP检查者仅发现肾发育不良2例。患侧肾小球滤过率（GFR）明显低于健侧（t=10.2，P<0.05）。结论：99mTc-DTPA肾动态显像是一种能有效诊断肾发育不良、并同时评价肾功能的无创性影像手段。
Abstract
Objective: To discuss the clinical application value of renal dynamic imaging in the diagnosis of patients with congenital renal dysplasia. Methods: Twelve cases with congenital renal dysplasia underwent 99mTc-DTPA renal dynamic imaging and abdominal ultrasound examination, 11 cases among them underwent abdominal enhanced CT scan, and 8 cases among them underwent intravenous pyelography(IVP). Results: Seven cases were diagnosed by 99mTc-DTPA renal dynamic imaging(58.3%, 7/12). The detection sensitivity by DTPA imaging was equivalent to enhanced CT scan(χ2＝1.5, P>0.05), and was superior to ultrasound(χ2＝4.4, P<0.05). Only 2 cases among 8 cases underwent IVP. The average values of GFR in the affected side kidney were obviously lower than normal side kidney(t=10.2, P<0.05). Conclusions: 99mTc-DTPA renal dynamic imaging is an effective tool to diagnose renal dysplasia and evaluate kidney function at the same time.
