UNILATERAL NEPHROLITHIASIS AND HYDRONEPHROSIS TREATED WITH NEPHRECTOMY IN A CAPTIVE MOUNTAIN TAPIR (TAPIRUS PINCHAQUE).
Mountain tapirs (Tapirus pinchaque) are endangered land mammals and there are few descriptions of urinary diseases that affect them. This report describes a 17-year-old mountain tapir presenting with hyporexia and chronic weight loss caused by unilateral nephrolithiasis and hydronephrosis. Unilateral nephrectomy returned this mountain tapir to normal weight with resolution of clinical signs. Characteristics of the smooth circular uroliths found in this mountain tapir were consistent with the rarer type II variant found in horses and was composed of 100% calcium carbonate. Type II uroliths in horses typically have amorphous shapes and include phosphate. This case showed that mountain tapirs are susceptible to nephrolithiasis, which may progress to hydronephrosis, and that unilateral nephrectomy is a feasible treatment. Despite the success of nephrectomy in this case, further investigation is required in captive mountain tapirs to more clearly understand management of nephrolithiasis and how it equates with what is known in horses.
期刊介绍：
The Journal of Zoo and Wildlife Medicine (JZWM) is considered one of the major sources of information on the biology and veterinary aspects in the field. It stems from the founding premise of AAZV to share zoo animal medicine experiences. The Journal evolved from the long history of members producing case reports and the increased publication of free-ranging wildlife papers.
The Journal accepts manuscripts of original research findings, case reports in the field of veterinary medicine dealing with captive and free-ranging wild animals, brief communications regarding clinical or research observations that may warrant publication. It also publishes and encourages submission of relevant editorials, reviews, special reports, clinical challenges, abstracts of selected articles and book reviews. The Journal is published quarterly, is peer reviewed, is indexed by the major abstracting services, and is international in scope and distribution.
Areas of interest include clinical medicine, surgery, anatomy, radiology, physiology, reproduction, nutrition, parasitology, microbiology, immunology, pathology (including infectious diseases and clinical pathology), toxicology, pharmacology, and epidemiology.
