摘要
目的探讨肾结石形成的影响因素和超声检查的诊断价值。方法使用凸阵探头,对158例肾结石患者进行超声检查,并与CT、X线平片和静脉肾盂造影进行对比分析。结果本组病例均有不同程度的腰部不适、肾绞痛和血尿等临床表现,超声检查表现为肾脏内强回声光团及其后方伴随声影的结石病灶显示,可引起肾周水肿,且肾周水肿的出现与结石发生的部位有关。结论肾草酸钙结石的形成可能与尿草酸排泄过多和草酸的代谢异常有关。伴随肾结石强回声后方的声影为肾结石的另一超声学表现,超声检查能清晰地显示肾内液区,对肾结石具有确诊价值。
Objective To investigate the diagnostic value of ultrasonographic examination and factors on nephrolithiasis. Methods 158 cases of kidney stones were examined by ultrasonography and all sonographic examinations were performed using curvilinear phased array probe, compared with those of CT, radiogram, intravenous pyelography. Results 158 cases were with different degrees of lumbar ache, nephritic colic and blood urine on clinical symptoms. There were the shadows of the calculi imaging showing strong echos on kidney ultrasonographic appearances. The kidney stones caused circumrenal edema at renal upper pole or lower pole, and the position of circumrenal edema had relation to the position of kidney stones. Conclusion The formation of urinary calcium oxalate stone probably relating to the oxalate load on urinary oxalate excretion and abnormal oxalate metabolism. The shadows showing strong echos of the calculi may be considered as an additional sonographic feature of kidney stones, ultrasonographic examination can show clearly fluid area in the kidney and diagnose accurately the kidney stones.
