摘要
【目的】利用超声背向散射积分(IBS)技术评价多发性骨髓瘤(MM)患者肾脏改变。【方法】选取MM患者71例,根据血肌酐水平分为MM无肾损害组(≤173umol/L,45例)及MM肾损害组(〉173μmol/L,26例),选取20例健康者作为对照。观察肾脏长度、体积、皮质与髓质IBS%等指标。【结果】MM无肾损害组肾脏长度、体积及皮质与髓质IBS%均正常,MM肾损害组肾长度及体积较无肾损害者稍减小、肾皮质及髓质IBS%均明显增高。左肾皮质IBS%和左肾髓质IBS%判断MM患者有无肾损害最佳阈值分别为80.1%、67.7%。【结论】MM肾损害患者肾脏稍变小,皮质及髓质IBS0.4均明显增高,利用左肾皮质及髓质IBS%可以较好的评价肾脏损害。
[Objective] To study the ultrasonic integral backscatter for assessing renal changes in patients with multiple myeloma(MM). [Methods] According to serum creatinine, 71 MM patients were divided into MM with- out renal impairment group( n=45, ≤173μmol/L) and MM with renal impairment group( n=26,〉173μmol/ L). Other 20 healthy people were selected as control group. The parameters such as length and volume of kidney and IBS% of renal cortex and medulla were observed. [Results] The length and volume of kidney and IBS% of re- nal cortex and medulla in MM without renal impairment group were normal. Compared with MM without renal im- pairment group, the length and volume of kidney in MM with renal impairment group slightly decreased, and IBS% of renal cortex and medulla obviously increased. The best threshold of IBS% of cortex and medulla of left kidney for discriminating between MM patients with and without renal impairment was 80. 1% and 67. 7%. [Conclusiol] The length and volume of kidney of MM patients with renal impairment slightly decreases, and IBS% of renal cortex and medulla obviously increase. The IBS% of cortex and medulla of left kidney can well as- sess renal impairment.
