目的探讨螺旋CT尿路成像 (CTU)对双肾盂输尿管畸形的诊断价值。 方法 选择2013年9月至2017年8月我院 收治的双肾盂输尿管畸形患者68例，均 进行螺旋CTU检查和超声检查，以手术结 果为标准，比较其检出情况。结果 螺旋 CTU双肾盂输尿管畸形准确检出者64例， 24例为单纯左侧双肾盂输尿管畸形，22 例为单纯右侧双肾盂输尿管畸形，3例为 单纯双侧双肾盂输尿管畸形，7例为双肾 盂输尿管畸形合并肾结石，5例为双肾盂 输尿管畸形合并输尿管结石，2例为右侧 输尿管畸形合并输尿管囊肿，1例为左侧 输尿管畸形合并输尿管异位开口。另有1 例误诊，3例无法确诊。螺旋CTU双肾盂 输尿管畸形准确检出率为94.12%，显著 高于超声双肾盂输尿管畸形准确检出率 的79.41%(P<0.05)。结论 CTU对双肾盂输 尿管畸形具有一定诊断价值。

Objective To explore the diagnostic value of spiral CT urography (CTU) for double renal pelvis ureter malformation. Methods 68 cases of patients with double renal pelvis ureter malformation treated in our hospital from September 2013 to August 2017 were selected for the study and were given spiral CTU and ultrasound. The surgical outcomes were used as standards to compare the detection results. Results 64 cases were accurately detected by spiral CTU with double renal pelvis ureter malformation, including 24 cases of simple left double renal pelvis ureter malformation, 22 cases of simple right double renal pelvis ureter malformation, 3 cases of simple bilateral double renal pelvis ureteral malformation, 7 cases of double renal pelvis ureter malformation with renal calculi, 5 cases of double renal pelvis ureteral malformation with ureteral calculi, 2 cases of right ureteral malformation with ureteral cyst and 1 case of left ureteral malformation with ectopic ureter opening. Another 1 case was misdiagnosed and 3 cases were undiagnosed. The accurate detection rate of spiral CTU was significantly higher than that of ultrasound in the detection of double renal pelvis ureter malformation (94.12% vs 79.41%) (P<0.05). Conclusion CTU has certain diagnostic value for double renal pelvis ureter malformation.
