A case of a 2-year-old female with right ectopic ureter opening in vestibule vaginae and without urinary incontinence is reported. Excretory urogram showed mild dilatation of the upper right segment with bilateral complete duplication. Right ectopic ureter some functioning upper segment of the kidney was reimplanted into the bladder to avoid surgical intervention for heminephrectomy. According to the retrograde ureterogram of ectopic ureter the running courses and shapes of the dilated distal portions of ureters were compared between two groups, ectopic ureter with incontinence and that without incontinence. We suppose the continence mechanism of ectopic ureter is kept when the running course of the ureter through some portion of the urethral sphincter musculature.
报告了一例2岁女性，其右侧异位输尿管开口于阴道前庭且无尿失禁。排泄性尿路造影显示右上段轻度扩张，双侧完全重复肾。将右侧异位输尿管及部分有功能的上段肾重新植入膀胱，以避免进行半肾切除术的手术干预。根据异位输尿管的逆行输尿管造影，比较了两组异位输尿管（有尿失禁和无尿失禁）扩张远端输尿管的走行和形态。我们推测，当输尿管走行穿过尿道括约肌肌肉组织的某些部分时，异位输尿管的控尿机制得以维持。
