输尿管口梗阻疾病的超声显像诊断价值

Ultrasonograghic Evaluation of Obstructive Disease at Ureterovesical Junction

报告资料完整经手术及病理证实的８６例输尿管口梗阻疾病的超声显像诊断结果，声像图所见患侧输尿管扩张内径为０．８～３．２ｃｍ。并发肾积水者７６例，占８８．４％。其中轻度肾积水３６例（占４７．４％），中度肾积水３７例（占４８．７％），重度肾积水３例（占３．９％）。超声显像对输尿管口梗阻病因的诊断符合率为９１．９％（７９／８６）。本文就输尿管口梗阻疾病的超声显像检查方法、声像图表现及诊断与鉴别诊断等问题进行了讨论。

This paper reports the ultrasonographic results of 86 cases of obstructive disease at ureterovesical junction. All the results were confirmed with the complete data of surgery and pathology. The. results showed the typical sonographic pattrern of the disease with ureter dilated in 0.8￣～3. 2cm in diameter. Of the 86 cases, 76 were complicated by hydronephrosis(88. 4% ), which include 36 cases in slight hydronephrosis (47. 4%), 37 cases moderate (48. 7%) and 3 cases serious (3. 9%). The accuracy wad 91.9% (19/86) for the etiological ultrasonographic diagnosis of obstructive disease at ureterovesical junction. The ultrasonographic procedure and method, the characteristics of sonographic Pattern, and the diagnosis and differential diagnosis of obstructive disease at ureterovesical junction are discussed.
