A Case of a Cat with Left Uterine Dysplasia and Kidney Defects

Abstract

Dysplasia of the left uterus and ipsilateral renal deficiency were confirmed during ovarian hysterectomy in a 6-month-old female mongrel cat. As the proximal part of the uterus could be accessed with the animal in the normal position, we resected it along with an ovary. Dysplasia of the cat's uterus is usually confirmed with a frequency of approximately 0.1%. In addition, it has been reported in other countries that 30% of cats with uterine dysplasia may have ipsilateral kidney defects. This is the first study from Japan reporting a kidney defect on the ipsilateral side in a cat with segmental uterine dysplasia. As ovariohysterectomy is one of the most frequently performed operations on cats in Japan, clinicians are more likely to encounter cases of uterine defects during this procedure. If uterine abnormalities are confirmed, it is necessary to assess for other ipsilateral embryological abnormalities in the cats.
