A rare case of an incompetent urethral sphincter associated with a unilateral single ectopic ureter is reported. Urinary incontinence persisted even after removal of a dysplastic kidney draining into the vagina. No neurological defect was found. Manual compression of the bladder elicited urine leakage from the urethra, and the urethral closure pressure was markedly low. Cystometry and voiding cystourethrography were normal. Continence was restored completely by a urethral sling operation.
报告了一例罕见的尿道括约肌功能不全合并单侧单根异位输尿管的病例。即使切除了向阴道引流的发育异常肾脏后，尿失禁仍持续存在。未发现神经缺陷。手动压迫膀胱会引起尿道漏尿，且尿道闭合压明显偏低。膀胱测压和排尿性膀胱尿道造影均正常。通过尿道悬带手术完全恢复了控尿功能。
