目的 探讨核素肾动态显像对输尿管结石的诊断价值 .并检测病情发展 ,确定治疗时机及疗效观察 .方法35例输尿管结石左侧 2 1例 ,右侧 2 7例 ,患者常规肾动态显像检测分肾功能 ,其中 2 3例行取石后复查 .综合分析动态图像 ,清除曲线 ,肾小球滤过率 (GFR) .结果 35例病人中病肾 48个 (肾功能受损轻度 12个 ,中度 18个 ,重度 9个 ,无功能肾 9个 ) .肾曲线受损为B段较低平 ,C段下降延迟、中度为基本呈抛物线型 .重度为低水平延长线型 .GFR随病程不同而有不同程度降低 .轻度GFR无明显降低、中度GFR下降较为明显 (p <0 .0 5 )、重度GFR降低更为明显 .无功能肾GFR均 <10ml/min .病程不同GFR在轻度、重度、无功能组前后无显著变化 (p >0 .0 5 ) ,中度受损组GFR明显增高(p <0 .0 5 ) .结论 肾动态功能对了解分肾功能 ,病情发展 ,选择治疗方法有很高价值 .
Objective To investigate the diagnostic value of radionuclide renal dynamic imaging in the diagnosis of ureteral calculi and to detect the progression of the disease and to determine the timing of treatment and observation of the curative effect.Methods Totally 35 cases of ureteral calculi were treated with 21 cases of left ureteral calculi and 27 cases of right ureteral calculi Detection of renal function, of which 23 routine stone review after a comprehensive analysis of dynamic images, clear curve, glomerular filtration rate (GFR) .Results 35 patients with pathological kidney 48 (mild impaired renal function 12 , Moderate 18, severe 9, non-functional kidney 9) .The renal curve was lower for the B segment, C segment decreased for the delay, moderate for the basic parabolic type, severe for the low level extension type.GFR With different duration of disease have different degrees of reduction.Mild GFR no significant reduction, moderate GFR decreased more significantly (p <0. 05), severe GFR decreased more significantly.Fifty kidney GFR were <10ml / min. The course of the disease is different There was no significant change of GFR in mild, severe and non-functional groups (p> 0.05), while GFR in moderately damaged group was significantly higher (p <0.05) .Conclusion The renal dynamic function is of great value in understanding the renal function, Disease progression, the choice of treatment has a high value.
