摘　　要：目的比较64排容积CT尿路造影(VCTU)、超声在诊断成人肾盂输尿管重复畸形的应用价值。方法选取2016年5月至2020年7月我院及广州医科大学附属第一医院泌尿外科收治的成人肾盂输尿管重复畸形病例58例,均行VCTU及超声检查,分析VCTU诊断结果,以手术病理结果为准,比较VCTU及超声对本病的诊断价值。结果手术病理显示:诊断为肾盂输尿管重复畸形共58例、65侧,其中单侧51例,双侧7例,VCTU准确判断55例为肾盂输尿管重复畸形(单侧48例+双侧7例)。以手术结果为准,VCTU准确检出的55例肾盂输尿管重复畸形中包括19例单纯右侧、17例单纯左侧、7例单纯双侧,肾盂输尿管重复畸形合并肾结石6例(结石直径2.6~4.0 mm),肾盂输尿管重复畸形并输尿管结石4例(结石直径2.8~4.3mm),1例为左侧输尿管畸形合并输尿管囊肿,2例难以确诊;以手术结果为准,VCTU准确检出肾盂输尿管重复畸形率为94.83%(55/58),高于超声75.86%(44/58)(P<0.05)。结论与超声相比,VCTU通过多种图像后处理可清晰显示重复畸形的肾盂、输尿管,诊断准确性高,为临床治疗提供依据,有临床价值。Objective To compare the value of 64-slice volume CT urography(VCTU)and ultrasound in diagnosing adult duplication of renal pelvis and ureter.Methods A total of 58 adult patients with duplication of renal pelvis and ureteradmitted to the hospital from May 2016 to July 2020 were enrolled.All of them were subjected to VCTU and ultrasound examination,and the diagnosis results of VCTU were analyzed.Taking surgical pathology results as the standard,the diagnostic value of VCTU and ultrasoundwas compared.Results Surgical pathology showed that there were 58 cases(65 sides)with duplication of renal pelvis and ureter,including 51 cases with unilateral duplication and 7 cases with bilateralduplication.VCTU showed that there were 55 cases with duplication of renal pelvis and ureter,including 48 cases with unilateral duplication and 7 cases with bilateralduplication.Taking surgical results as the standard,there were 55 cases with duplication of renal pelvis and ureter accurately detected by VCTU,including 19 cases with simple duplication on the right side,17 cases with simple duplication on the left side,7 cases with simple duplication on bilateral sides,6 cases with duplication of renal pelvis and ureter complicated with kidney stones(2.6~4.0 mm),4 cases with duplication of renal pelvis and ureter complicated with ureteral calculi(2.8~4.3 mm),1 case with left ureteral malformation and ureteral cyst,1 case with right ureteral malformation and ectopia of uretal orifice,1 case with duplication of renal pelvis and ureter complicated with ureteral calculi who was misdiagnosed as simple kidney stones,and 2 cases could not be confirmed.Taking surgical results as the standard,the accurate detection rate of duplication of renal pelvis and ureter by VCTU was94.83%(55/58),higher than 75.86%(44/58)by ultrasound(P<0.05).Conclusion Compared with ultrasound,VCTU can clearly display duplication of renal pelvis and ureter with a high diagnostic accuracy,which provides reference for clinical treatment.
