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.
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.
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.
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.
狨猴，Callithrix spp，是一种小型新世界猴子，已成为人类实验动物模型的重要物种。尽管已经被广泛应用，但关于其肾脏形态学、血管化和位置的信息仍然有限。因此，本研究将为应用研究和比较解剖学提供基础解剖学知识。
从大西洋森林生物群落的高速公路上收集了 50 具狨猴尸体，对其进行识别并注入 10%甲醛溶液。然后，对标本进行解剖，并记录肾脏和肾血管的测量值和 topography。雄性和雌性的左肾和右肾均显著较大。
在研究的标本中，雄性的平均体长为 20.00±2.46cm，雌性的平均体长为 20.50±1.98cm（p=0.43）。Callithrix spp 的肾脏形状对称，类似于“豆形”。它们的颜色呈浅棕色，表面光滑。在雄性中，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%）。在雌性中，右肾最常见的位置是 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%）雄性和 9 名（36%）雌性中，肾脏位于同一水平。
在两性中，体长与肾脏长度之间存在正相关和显著的线性关系。无论肾脏在两侧的位置如何变化，右肾总是比左肾更靠近颅侧，这与其他非人类灵长类动物的观察结果相似。
