Abstract：
BACKGROUND: Marmosets, Callithrix spp, are small New World monkeys that have gained importance as an experimental animal model for human. Despite its use, information on its renal morphometry, vascularization, and location are limited. Therefore, this study will supply basic anatomy for applied studies and for comparative anatomy.
METHODS: Fifty cadavers of Callithrix spp were collected on highways from the Atlantic Forest biome, identified and injected with a 10% formaldehyde solution. Later, the specimens were dissected and the measurements and topography of the kidneys and renal vessels were recorded. Both left and right kidneys were significantly larger in females.
RESULTS: In the specimens studied, the average body length was 20.00 ± 2.46 cm in males and 20.50 ± 1.98 cm in females (p = .43). The kidneys of the Callithrix spp. were symmetrical in shape and resembled a \"bean.\" They were also pale brown with a smooth surface. In males, the most frequent location of the right kidney was at the L1-L2 level (92%), while the location of the left kidney was between L2 and L3 (76%). In females, the most frequent location of the right kidney was at the L1-L2 level (56%), while the location of the left kidney was between L2 and L3 (32%) (Table 1). However, in seven (28%) males and nine (36%) females, the kidneys were at the same level.
CONCLUSIONS: In both sexes, there was a positive and significant linear correlation between body length and kidney length. Regardless of the variable location of the kidneys in both sides and in either sexe, the right kidney was always located more cranially than the left, similar to observations in other non-human primates.

摘要：
背景：Marmosets，Callithrixspp，是新世界的小猴子，已成为人类实验动物模型的重要性。尽管它使用,关于其肾脏形态测量的信息，血管化,位置有限。因此,本研究将为应用研究和比较解剖学提供基础解剖学。
方法：在高速公路上从大西洋森林生物群落中收集了50具Callithrixspp的尸体，确认并注射10%甲醛溶液.稍后，解剖标本，并记录肾脏和肾血管的测量值和形貌。女性的左肾和右肾均明显较大。
结果：在所研究的样本中，男性平均身长为20.00±2.46厘米，女性为20.50±1.98厘米（p=0.43）。Callithrixspp的肾脏。形状对称，类似于“豆”。“它们也是浅棕色，表面光滑。在男性中，右肾最常见的位置是L1-L2水平（92％），而左肾的位置在L2和L3之间(76%)。在女性中，右肾最常见的位置是在L1-L2水平（56％），而左肾的位置在L2和L3之间(32%)(表1)。然而,在7名(28%)男性和9名(36%)女性中，肾脏处于同一水平。
结论：在两性中，体长和肾脏长度之间存在正相关和显着的线性相关。无论两侧和性别的肾脏位置如何，右肾的位置总是比左肾靠头颅,与其他非人灵长类动物的观察结果相似。
