Renal agenesis is a medical condition where one or both kidneys fail to develop properly before birth. This means that a person may be born with one kidney (unilateral renal agenesis) or no kidneys at all (bilateral renal agenesis).
Pathophysiology
- Structure:
- Kidneys are two bean-shaped organs located in the lower back. They filter waste from the blood, regulate blood pressure, and maintain the body’s fluid balance.
- In renal agenesis, one or both kidneys are either absent or very small.
- Blood Supply:
- The kidneys receive blood through the renal arteries, which branch off from the abdominal aorta. In cases of agenesis, the blood flow to the absent kidney is not established.
- Nerve Supply:
- Kidneys are innervated by the autonomic nervous system, which controls involuntary body functions. The absence of a kidney affects this nerve supply but often does not lead to noticeable symptoms.
Types of Renal Agenesis
- Unilateral Renal Agenesis:
- One kidney is absent. The other kidney usually grows larger to compensate.
- Bilateral Renal Agenesis:
- Both kidneys are absent. This is a more severe condition and can be life-threatening.
Causes of Renal Agenesis
Here are 20 possible causes:
- Genetic Factors: Certain genes may predispose individuals to renal agenesis.
- Environmental Factors: Exposure to certain drugs or chemicals during pregnancy.
- Maternal Health: Conditions like diabetes or hypertension during pregnancy.
- Infections: Maternal infections that affect fetal development.
- Vascular Issues: Problems with blood supply to the developing kidneys.
- Chromosomal Abnormalities: Conditions like Turner syndrome.
- Teratogenic Effects: Substances that disrupt normal development.
- Smoking: Maternal smoking can increase risks.
- Obesity: Maternal obesity may impact fetal development.
- Advanced Maternal Age: Older mothers may have higher risks.

- Multiple Gestations: Higher risk in twins or triplets.
- Family History: A family history of renal issues.
- Abnormal Placenta: Issues with the placenta’s health can affect development.
- Exposure to Radiation: Radiation during pregnancy.
- Medication Side Effects: Certain medications may cause issues.
- Chronic Illnesses: Conditions like lupus in the mother.
