| 摘 要： | 目的分析输尿管膀胱壁内段结石并发膀胱充盈缺损(bladder filling defect,BFD)的CT征象以及两者的关系。资料与方法回顾分析52例急性肾绞痛患者伴输尿管膀胱壁内段结石的CT图像,包括结石是否伴BFD,结石的大小和梗阻情况与BFD的关系。结果52例中,32例可见BFD,其中28例为形态规则的充盈缺损,4例为形态不规则的充盈缺损。在输尿管膀胱壁内段结石伴有BFD阳性者中,69.5%出现明显的输尿管梗阻征象。输尿管膀胱壁内段结石伴有BFD阳性者结石平均直径为4.01mm,阴性者平均直径为4.55mm,结石大小与BFD征象无明显关系(P>0.05)。结论急性肾绞痛患者中,膀胱充盈缺损征阳性强烈提示膀胱输尿管口的钙化为结石。

| Abstract: | Objective To evaluate the prevalence of a bladder filling defect (BFD)in patients with ureterovesical junction calculus,and to analyze the relationship between the BFD with the calculi. Materials and Methods Ureterovesical junction calculi was confirmed to be present in 52 patients who had acute renal colic. The CT features including the presence or absence of the BFD,the sizes of calculi and the degree of obstruction were reviewed retrospectively. Results 32 patients had the BFD which was located at ipsila... |
