摘　　要：目的:探讨MRI在输尿管开口异位畸形及其合并畸形诊断中的价值。方法:回顾性分析经手术证实的21例输尿管开口异位患者的临床及影像资料。结果:输尿管异位开口于阴道12例,异位开口于尿道1例,异位开口于尿道前庭1例,异位开口于后尿道或直肠前间隙6例,异位开口于膀胱颈部1例。结论:MRI在显示扩张的集合系统、异位输尿管方面更有优势,能更好地提示输尿管开口异位于膀胱外及其合并畸形,有利于连续完整地显示尿路畸形,做出全面正确的诊断。Objective：To investigate the value of MRI in the diagnosis of ectopic ureter insertion. Methods：The clinical and imaging material of 21 patients with surgery proven ectopic ureter insertion were retrospectively analyzed. Results： 12 patients had ectopic ureter inserted into vagina; 6 patients into posterior urethra or anterior rectal space; ectopic ureter in- serted into urethra,into urethral vestibule,and into the neck of bladder was seen for 1 patient each. Conclusion： MRI is supe- rior for the assessment of urinary tract morphology which could demonstrate the ectopic extravesical ureteric insertion and its associated anomalies,is helpful in displaying the whole course of urinary tract as well as its malformation,and is important for the accurate diagnosis.
