Nineteen cases of feline congenital urinary incontinence (10 cats with ureteral ectopia and nine with incompetence of the urethral sphincter mechanism) are reviewed. The 10 cats with ureteral ectopia are considered together with 13 from previous reports. There was no apparent breed predisposition. Most of the 23 cats were presented for urinary incontinence but two of them were continent. Thirteen were females and ectopia was unilateral in 13 and bilateral in 10. Twenty-eight of 31 ectopic ureters terminated in the urethra. The commonest complication was hydroureter/hydronephrosis (10 cases). Eighteen of the cats were treated surgically, 13 by ureteral transplantation, four by ureteronephrectomy and one by ligation of the renal blood vessels; 16 of them were cured by surgery. Congenital urethral sphincter mechanism incompetence has not been reported previously in the cat. Nine cases are presented and the urethras of all were markedly hypoplastic. A common concomitant abnormality was vaginal aplasia, with the uterine horns terminating in the dorsum of the bladder. Bacteriuria was more common in this group than in the cats with ureteral ectopia.
回顾了19例猫先天性尿失禁病例（10例输尿管异位和9例尿道括约肌功能不全）。将10例输尿管异位的猫与之前报告中的13例放在一起考虑。没有明显的品种易感性。23只猫中的大多数因尿失禁就诊，但其中2只能够自主控制排尿。13只为雌性，13例输尿管异位为单侧，10例为双侧。31条异位输尿管中有28条终止于尿道。最常见的并发症是输尿管积水/肾盂积水（10例）。18只猫接受了手术治疗，13例行输尿管移植，4例行输尿管肾切除术，1例行肾血管结扎术；其中16只通过手术治愈。先天性尿道括约肌功能不全在猫中此前未见报道。本文报告了9例，所有病例的尿道均明显发育不全。常见的伴随异常是阴道发育不全，子宫角终止于膀胱背侧。该组猫的菌尿比输尿管异位的猫更常见。
