Urinary incontinence after surgical repair of ureteral ectopia in dogs.

Eleven of 20 dogs (55%) were incontinent after surgical treatment of ureteral ectopia. Ureterocystostomy was performed in 15 dogs, ureteral transection and bladder reimplantation in four dogs, and ureteronephrectomy in one dog. Siberian huskies had a significantly higher rate of persistent postoperative incontinence than other breeds. There was no difference in postoperative incontinence between dogs with unilateral and bilateral ectopia. Concurrent bacterial cystitis was not associated with persistent postoperative incontinence. Age at the time of surgical correction had no effect on the rate of postoperative incontinence. Eight incontinent dogs were treated medically; three are continent with medication, three are improved but still incontinent, and two did not improve.
