Ultrasonographic evaluation of the renal dimensions in captive tigers

Abstract

Ultrasonographic measurements of kidney size are useful in the practical diagnosis of kidney diseases in animals. In tigers, there is a lack of information regarding the ultrasonography methods used to measure the kidney size of the tiger. Thirty-three healthy captive tigers (Panthera tigris) were placed in lateral recumbency for ultrasonography. The measurements obtained from the ultrasonography were computed, and the results showed that there was a statistically significant difference between genders in terms of body weight and renal length. The length of the right kidney was significantly different from that of the left kidney (10.23 ± 0.76 cm in males versus 9.94 ± 0.80 cm in females; P<0.05). Interestingly, this study demonstrated that kidney length was statistically significantly associated with the body weight, and it also had a positive linear relationship with the body weight. Therefore, ultrasonographic renal dimensions could prove to be beneficial and modality for use in the evaluation of kidneys in unconscious tigers. However, kidney size evaluation must be performed using not only ultrasound but other clinical forms of technology and parameters.

Profiling and bioinformatic analysis reveal differential microRNA expression in the left and right kidneys in normal mice

“…Lauder et al [7] demonstrated that the right main renal artery was longer than the left, but the left renal artery had a greater diameter in patients with hypertension. There is significant difference between right and left kidney length among schoolage children [8] and nondiabetic patients without CKD [9]. In a study performed by Ito et al [10], the differences in apparent diffusion coefficient (ADC) values of each kidney during different cardiac phases were compared.…”
