Bilateral renal agenesis is characterized by the absence of kidneys and of urine in a baby. The face usually consists of wide-set eyes; a “parrot beak” nose; a receding chin, and large low set ears deficient in cartilage. Other symptoms may include excess and dehydrated skin, a prominent fold at the corner of each eye, the facial expression of an older infant, and deformities of the hands and feet.
Premature labor, breech delivery and a disproportionately low birthweight are often associated with bilateral renal agenesis. The baby may also have multiple malformations including in females the absence of a uterus and upper vagina, or in males an absence of seminal vesicles and spermatic duct. Gastro-intestinal malformations such as the absence of a rectum, esophagus and duodenum may also occur. Symptoms may further include the presence of only a single umbilical artery, and major deformities of the lower part of the body and the lower limbs.
