输尿管末端正常开口于膀胱三角区内,但由于胚胎期间发育异常,有时出现单侧或双侧重复肾和重复输尿管,并且往往其中一根输尿管终止于异常位置。如果其终止位置超出膀胱括约肌,在女性除显示正常排尿外,并自幼出现尿失禁症状。本病虽不常见,但因外科治疗的效果卓著,所以在诊断上是值得重视的。我院在1978和1979两年内先后收治三例,均获成功,兹报告如下:例一:李××,女,10岁,学生。患儿自幼每天尿液滴沥不尽,但又能定时从尿道排尿。尿次白天4~5次,晚上0~1次,每次尿量约100~150ml,尿液清亮。无尿频、尿急、尿痛及血尿史。在当地经药物治疗,未见好转;曾试行控制饮食及饮水,但尿失禁依然如故。入院检查:患儿发育营养正常,见患儿前庭部尿道口右外侧0．5cm处有一直径1mm之裂隙,不断有尿液溢出,每分钟约3—5滴。行排泄性尿路造影,

If the termination position beyond the bladder sphincter, in addition to showing normal urination in women, and childhood urinary incontinence. Although the disease is not common, but the effect of surgical treatment is remarkable, so the diagnosis is worthy of attention. Three cases were admitted to our hospital in 1978 and 1979, all of which were successful. The report is as follows: Example 1: Li XX, female, 10 years old, student. Urine drip dripping urine every day since childhood, but also regular urination from the urethra. Urine times 4 to 5 times a day, 0 to 1 night, each urine output of about 100 ~ 150ml, urine clear. Urinary frequency, urgency, dysuria and hematuria history. In the local drug treatment, no improvement; have tried to control diet and drinking water, but urinary incontinence remains the same.
