Abstract

A 3-year-old, female spotted hyena (Crocuta crocuta) was referred with dystocia. The hyena had been in labor for over 5 days, but she failed to expel the infant. The blood biochemistry profiles showed severe azotemia. During caesarian section, we confirmed that the uterus had expanded and contained 1 dead, decayed infant, which compress the urethra, leading to the expansion of the urinary bladder and that the dead fetus was nearly 3 kg in weight (approximately 5% of the maternal weight). Thus, we confirmed that the dystocia caused by oversized fetus and malposture, and the severe azotemia resulted in compression of the urethra by fetus in the hyena. This report is the first to show that the dystocia can induce postrenal azotemia in female spotted hyenas.

3년령, 암컷 점박이 하이에나가 분만의 증상을 나타내나 분만이 이루어지지 않아 이를 교정하기 위해 충북대학교 동물의료센터에 의뢰되었다. 분만 징후가 관찰된 후 5일이 경과되었고, 스스로 분만이 불가능하였기 때문에 제왕절개를 계획하였다. 수술 전 혈액화학검사 결과 심각한 질소혈증이 관찰되었으며, 수술 중 골반입구를 폐쇄하고 있는 태아의 두부가 요도를 압박하여 배뇨가 불가능하였음을 확인하였다. 또한 확장된 자궁내의 태아는 견관절굴절위를 나타내고 있었으며, 태아의 두부가 골반입구로 진입할 수 없을 정도의 크기를 나타내고 있었다. 태아의 상태는 폐사 후 부패가 진행된 상태였으며, 과다 체중(모체의 약 5%)을 나타냈다. 이 증례는 점박이 하이에나에서 과대태아 및 견관절굴절위로 인한 난산이 신후성 질소혈증을 일으킨 최초의 보고이다.
