Complete absence of kidneys was observed in 3 neonatal guinea pigs which died 2-3 da after birth. Congestion of intestines and other organs was also observed. Renal agencies in the guinea pigs appeared to be of rare occurrence. Agenesis of right kidney was observed in 2 of over 500 opossums examined. Both opossums were males, and the corresponding ureters were smaller in diameter than the contralateral ureters. The left kidney was enlarged as a result of compensatory hypertrophy. The lumina of right ureters were found to be obliterated on microscopic examination.
在3只出生后2 - 3天死亡的新生豚鼠中观察到完全没有肾脏。还观察到肠道和其他器官的充血。豚鼠的肾发育不全似乎很少见。在检查的500多只负鼠中，有2只观察到右肾缺如。这两只负鼠均为雄性，相应的输尿管直径比另一侧输尿管小。由于代偿性肥大，左肾增大。显微镜检查发现右输尿管腔闭塞。
