Abstract

An 8-year-old spayed female, Yorkshire terrier dog was presented with a urinary incontinence. Unaware urine dribbling during sleeping was observed eight months after spaying. Polyuria and polydipsia were also reported. Physical examination revealed obesity and hypertension. Characteristic laboratory findings in this dog were polycythemia, hyperlipidemia and elevated hepatic enzyme. Other causes of the urinary incontinence were ruled out through further diagnostic tests and spay-related urethral sphincter mechanism incompetence (USMI) was made as a presumptive diagnosis. In addition, the dog was also diagnosed with pituitary-dependent hyperadrenocorticism. Both conditions can cause urinary incontinence in dogs; therefore, definite diagnosis was made through a therapeutic approach. The synthetic estrogen, diethylstilbesterol, was initially administered and successfully managed the urinary incontinence in this dog. To the best of the author's knowledge, this is the first case report describing the clinical and laboratory features of spay-related USMI concurrent with hyperadrenocorticism and treatment outcomes in our country.

8연령의 암컷 요크셔 테리어견이 요실금을 주증으로 내원하였다. 환축은 요실금 증상이 나타나기 이전부터 다음다뇨 증상을 가지고 있었으며, 난소제거 8개월 이후 야뇨증이 나타났다. 신체검사 상에서 비만과 고혈압이 확인되었다. 실험실 검사에서 적혈구증가증, 지질혈증 및 간수치 증가가 관찰되었다. 다양한 검사를 통하여 난소제거 이후 발생한 요도 괄약근 기능부전증이 가장 의심되었다. 이와 더불어 본 환축은 부신피질기능 항진증을 가진 것으로 진단되었다. 합성 에스트로겐인 디에틸스틸베스테롤을 통한 치료적 접근에서 요실금 증상의 개선이 확인 되었으며, 이를 통하여 요도 괄약근 기능부전증이 요실금의 원인으로 확진 되었다. 결론적으로 본 증례는 부신피질기능 항진증과 더불어 암캐의 난소 제거 이후 발생한 요도 괄약근 기능부전의 임상증상과 실험실 검사 결과 그리고, 치료 반응에 대한 국내 첫 증례보고이다.
