Abstract

A one-month-old, 0.9 kg BW, male Korean Sapsal dog with anorexia, anuria, ataxia and depression was referred. On physical examination, the dog was showed tachycardia, hypothermia and pale mucous membrane. Hematologic values showed leukocytosis and mild anemia. Serum chemistry profile results revealed increased BUN (57.3 mg/dl) and $NH_3$ ($584\;{\mu}g/dl$), decreased albumin, sodium and potassium. Urinalysis showed hematuria, proteinuria, glucosuria, bacteriuria (Staphylococcus spp.) and magnesium ammonium phosphate crystalluria. On radiographic finding, urinary bladder was enlarged and 2 mm diameter radiopaque urolith was showed between os penis and prescrotal region. Urolithiasis was surgically corrected by urethrostomy.

생후 1개월령의 0.9 kg수컷 삽살개가 식욕부진, 배뇨곤란, 기립곤란, 침울을 주증으로 병원에 내원하였다. 신체검사에서는 빈맥, 저체온증, 점막창백 소견을 보였다. 혈액검사에서는 백혈구증가증과 빈혈소견이 있었고, 혈청생화학검사에서는 BUN (57.3 mg/dl)과 $NH_3$ ($584\;{\mu}g/dl$)의 증가, 알부민과 나트륨 및 칼륨의 저하소견을 보였다. 뇨검사에서는 혈뇨, 단백뇨, 당뇨, 세균뇨(Staphylococcus spp.)와 인산암모늄마그네슘결정뇨의 소견을 보였다. 방사선 검사에서는 확장된 방광과 요도내 2 mm크기의 결석을 발견할 수 있었다. 요도절개술로 요도내 결석을 제거하였고, 수술 후 환자는 정상적으로 회복되었다. 본 케이스는 요소분해효소 생산 세균의 감염과 고암모니아증을 동반한 어린 삽살개에서 스트루바이트 결석증 발생하였음을 보고한다.
