초록

하부 비뇨기계 폐색을 주증상으로 내원한 11살령의 암컷 시쭈견에서 실시한 초음파 검사에서 뚜렷한 경계를 가지는 저에코의 종괴가 근위 요도의 내강에서 관찰되었다. 조영 검사를 통해 요도의 완전 폐색을 확인하였고, 종양의 범위를 평가하여 방광은 이상 소견이 없으며 종괴가 요도에만 국한하여 발생한 것을 확인하였다. 이를 바탕으로 근위요도에서 유래한 원발성 종양으로 잠정 진단하였다. 수술적으로 종괴와 요도를 함께 제거한 후 요도 문합술을 실시하였다. 이후 임상 증상은 모두 소실되었다. 조직 검사를 통해 종괴는 평활근종으로 진단되었다. 하부 비뇨기계 유래 평활근종은 매우 드물게 보고되어 있으며, 본 보고에서는 영상 진단 과정과 수술적 교정에 대해 소개하였다.

An 11-year-old, intact female Shihtzu showing anuria was diagnosed as a urethral leiomyoma. The tumor occupied and obstructed the urethral lumen. In this report, the urethral tumor and secondary obstruction could be diagnosed via ultrasonography and contrast study such as excretory urography and voiding urethrography. Ultrasonography revealed a hypoechoic, demarcated urethral mass in proximal urethra. Contrast study confirmed the urethral obstruction and ruled out the expansion of the tumor into the urinary bladder. The clinical signs of the dog were completely resolved after removing the urethral mass and urethral anastomosis. Leiomyoma is a benign smooth muscle tumor, and rarely reported in lower urinary tract.
