先天性输尿管不全梗阻的X线与B超表现分析

目的：探讨先天性输尿管不全梗阻的X线与B超表现，提高对本病的认识水平。方法：回顾性分析24例先天性输尿管不全梗阻的X线B超检查资料。全部病例均经静脉尿路造影(intravenous urograghy，IVU)，8例行逆行尿路造影(retrograde ruography，RUG)，4例行经皮肾穿刺造影，3例行经肾造瘘造影；24例均行B超检查。结果：24例均经手术及病理证实，输尿管狭窄16例；迷走血管压迫3例，1例伴肾旋转不良；纤维束带粘连、牵拉和压迫3例；输尿管瓣膜形成2例。泌尿系造影诊断符合率为80．7％、B超诊断符合率为58．3％，两者互补诊断符合率为100％。结论：静脉尿路造影、逆行尿路造影、经皮肾穿刺造影和B超检查优势相互弥补，可对此病做出较确切诊断。

The diagnostic value of X-ray and B-ultrasound in 24 cases with congenital ureter obstruction

Objective:To explore the value of X-ray and B-ultrasound in diagnosis of congenital ureter obstruction in order to improve the recognition of the disorder.Methods:The data of 24 cases with congenital ureter obstruction diagnosed with X-ray and B-ultrasound were analyzed retrospectively. The diagnosis of the disease was confirmed by intravenous urography (IVU) in all the 24 cases, retrograde urography (RUG) in 8 and percutaneous trans-renal puncture in 4. All the cases in this group were also examined by B-ultrasound.Results:The main causes for the disease included ureteric stenosis in 16 cases, pressure by vagrant vessel in 3, renal mal-rotation in one, adherence, attraction and pressure of fibrous band in 3, and formation of ureteric valve in 2. The agreement of urography in diagnosis of the disease was 80.7%. The agreement of B-ultrasound in the diagnosis of the disease was 58.3%. When both urography and B-ultrasound were used,the agreement diagnosis of the disease was 100%. All cases were confirmed by operation and pathological examination.Conclusion:IVU,RUG and percutaneous trans-renal puncture are common and useful methods in the diagnosis of congenital ureter obstruction. If both X-ray and B-ultrasound exams are used, generally, the diagnosis can be made correctly.
