“…Congenital abnormalities accounted for only 18% of our series of incontinent cats and included 4 cats with congenital spinal canal malformations (eg, Manx syndrome or spinal dysraphism), 1 cat with bilateral ureteral ectopia, 2 cats with presumed congenital USMI, and 1 cat with urethral hypoplasia . These and other congenital causes of UI in cats have been reported previously .…”

“…In our series of cats, UI was associated with a variety of congenital and acquired disorders that affected both phases of micturition with similar frequency. The proportional morbidity of causes, sex, age distribution, and outcomes of UI in our series of cats differed substantially from previous reports of UI in cats and dogs . Our observations indicated that spinal cord disorders were a common cause of UI in cats and were associated with less favorable outcomes compared to bladder and urethral disorders.…”

However, descriptions of disorders associated with UI in cats often have been limited to anecdotal case reports or selected case series.…”

Background: In contrast to dogs, the causes and outcomes of urinary incontinence (UI) in cats are largely unknown.Objectives: To determine the causes, identify comorbid conditions, and assess outcomes of cats with micturition disorders presenting as UI.Animals: Forty-five cats with UI.Methods: Retrospective study. Medical records of cats presented from January 2006 to December 2017 were searched using 45 keywords related to UI. History, presenting complaint, and physical examination findings were used to confirm a diagnosis. Cases were categorized based on functional and anatomic localizations.Results: Forty-five cats met inclusion criteria. Spinal cord disease was the most common cause of UI (n = 18), followed by urethral (n = 17), bladder (n = 9), and ureteral (n = 1) disorders. Proportions of voiding and storage phase disorders were similar (53% and 47%, respectively). However, voiding-phase disorders were observed more frequently in males and younger-aged cats (P < .03). Urinary tract infection was detected in 11 of 28 (39%) cats. Outcomes were available in 38/45 cases; 16 cats (42%) regained continence, 3 (8%) improved with treatment, and 19 (50%) remained incontinent or were euthanized. Multiple variable logistic regressions indicated that spinal cord disease was significantly more likely to be associated with poor outcomes compared to bladder or urethral disorders (P < .04).Conclusions and Clinical Importance: Urinary incontinence in cats was associated with a variety of congenital and acquired disorders that affected both phases of micturition with similar frequency. Incontinent cats with spinal cord disorders were common and warrant a more guarded prognosis than do cats with bladder or urethral disorders.

A 6‐months‐old male intact Maine Coon cat presented for investigation of urinary incontinence and a palpable mass in the right cranial abdomen. Abdominal ultrasonography (US) revealed marked right hydronephrosis and hydroureter and raised a suspicion of ureteral ectopia, but the exact location of the ureterovesical junction was not visualised. Abdominal CT was performed and provided excellent information about opening of the ureter and confirmed the diagnosis of right extramural ureteral ectopia. The patient underwent ureteronephrectomy and recovered without complications. No urinary incontinence was detected after surgery. The patient continues to do well and remains free from clinical signs up to date. This is the first case report describing the use of CT and US in diagnosis of a rare anomaly of ureteral ectopia in a cat. It also highlights the important role of diagnostic imaging modalities in investigating and treatment planning of ectopic ureters in feline patients.

ObjectiveTo describe the signalment, treatment, complications, and outcomes of cats treated surgically for ectopic ureters.Study designRetrospective, multi‐institutional study.AnimalsTwelve client‐owned cats.MethodsMedical records of cats diagnosed with unilateral or bilateral ectopic ureters were reviewed and analyzed. Data reported included signalment, clinical signs, diagnostics, open celiotomy, or cystoscopic surgical interventions, and outcomes.ResultsSeven of the 12 cats in the study population were female or female spayed and the median age at time of presentation was 4 years, with an interquartile range (IQR) of 6 months–14 years. Presurgical diagnostic imaging diagnosed ectopic ureters by abdominal ultrasound (8/10), contrast enhanced computed tomography (3/3), fluoroscopic urography (3/4), or cystoscopy (6/7). Eight of 12 cats had extramural ectopic ureters and six cats were affected bilaterally. Eight affected cats underwent ureteroneocystostomy, one cat underwent neoureterostomy, two cats underwent cystoscopic laser ablation, and one cat underwent nephroureterostomy. Immediate postoperative complications occurred in three cats; one cat required additional surgical intervention. Short‐term complications occurred in three cats, and long‐term complications in two cats. All cats that underwent surgical or cystoscopic intervention had improvement of their urinary incontinence scores, with complete resolution in 11 cats.ConclusionSurgical correction of ectopic ureters in cats is associated with good long‐term outcomes. Ectopic ureters in cats are commonly extramural and bilateral. Postoperative outcomes were acceptable and there were few postoperative complications, with varying forms of surgical correction.Clinical significanceEctopic ureters in cats are rare but urinary incontinence can be corrected or improved successfully with surgery.
