目的:评价肾动态显像后排尿再显像和侧位显像及必要时实测肾脏深度的临床价值。方法:对310例肾动态显像患者的影像结果进行回顾分析。结果:(1)肾动态显像与排尿后再显像肾盏、肾盂放射性滞留差异有显著性(P<0.01)。(2)肾后位显像小者,与侧位显示肾脏大小差异有显著性(P<0.01)。(3)特殊体型者常规计算与实测肾脏深度所得GFR值差异有显著性(P<0.01)。结论:肾动态显像后排尿再显像和侧位显像及对特殊体型者肾脏深度进行实测,可提高上尿路引流不畅的诊断率和GFR的准确性。
OBJECTIVE: To evaluate the clinical value of urinalysis and lateral imaging after renal dynamic imaging and to measure the depth of kidney when necessary. Methods: The imaging results of 310 patients with renal dynamic imaging were retrospectively analyzed. Results: (1) There was a significant difference in the radioactive retention between renal dynamic imaging and renal calyx after urination (P <0.01). (2) Small posterior kidney imaging showed significant differences in kidney size compared with those in lateral (P <0.01). (3) There was a significant difference (P <0.01) between the GFR values calculated by conventional calculation and measured kidney depth in special body types. Conclusions: Urinalysis and lateral scintigraphy after renal dynamic imaging and the measurement of kidney depth of special body type can improve the diagnosis rate of poor upper urinary tract drainage and the accuracy of GFR.
