A case of ectopic ureter without urinary incontinence despite its ureteral orifice in the vestibulum is reported. A 2-year-and-9-month-old female was referred to our hospital with the pain of external genitalia, pollakisuria and macroscopic hematuria. Examination revealed a complete double system of the left upper tract with vestibular opening from the upper moiety. She did not show any signs of ureteric incontinence after the establishment of voiding habits. Because radioisotope (RI) scintigram showed apparent uptake in the upper half of the left kidney we performed left ureterocystoneostomy with psoas hitch procedure. We postulate that the incontinence mechanism is maintained when the running course of the ectopic ureter is through some portion of the urethral sphincter musculature. This is the 10th case reported in Japan.
本文报告了一例异位输尿管病例，尽管输尿管口位于前庭，但未出现尿失禁症状。一名2岁9个月大的女性因外生殖器疼痛、尿频和肉眼血尿被转诊至我院。检查发现左上尿路完全重复畸形，上半部分有前庭开口。在养成排尿习惯后，她未表现出任何输尿管失禁的迹象。由于放射性同位素（RI）闪烁扫描显示左肾上部有明显摄取，我们进行了左输尿管膀胱吻合术并采用腰大肌悬吊术。我们推测，当异位输尿管的走行经过尿道括约肌肌肉组织的某些部分时，失禁机制得以维持。这是日本报告的第10例病例。
