Is it suitable for someone born with a congenital kidney deficiency to become pregnant?


Hello Dr.
Yang,
I recently underwent an examination due to gastritis, and during the ultrasound, it was discovered that I only have one kidney.
Additionally, my liver detoxification function is not good.
What should I pay attention to in my daily life? Also, since I have a uterus with a double configuration, am I suitable for pregnancy? I have a friend who, like me, has one kidney and a double uterus.
She has two children; the eldest has congenital heart disease, and the younger one also has only one kidney.
Is this type of congenital condition hereditary? Thank you for your assistance.

Xiao Qi, 20~29 year old female. Ask Date: 2002/06/18

Dr. Yang Jun reply Internal Medicine


Hello, Xiao Qi: In response to your inquiry, I will address your questions in three parts:
1.
The human body has two kidneys, and as long as one kidney functions normally, the body can effectively excrete toxins, regulate water, maintain electrolyte balance, control blood pressure, and support hematopoiesis.
Individuals who are born with or lose one kidney due to congenital or acquired factors must take care to protect their remaining kidney.
It is advisable to reduce salt and oil intake in daily life and to undergo regular health check-ups, including urine tests and kidney function assessments or ultrasounds, annually.
2.
If kidney function tests are normal, pregnancy should not adversely affect bodily functions.
However, if there is a decline in kidney function, it is advisable to consult a nephrologist and closely monitor kidney function.
3.
Congenital absence of one kidney is influenced by individual genetics or acquired factors and is not related to heredity.
However, some kidney diseases are hereditary, such as "congenital polycystic kidney disease," and direct relatives of affected patients should undergo screening.

Women with one kidney and a condition known as uterus didelphys can indeed become pregnant, but there are several important considerations and potential risks involved in such pregnancies. Uterus didelphys is a congenital anomaly where a woman has two uteri, two cervices, and sometimes two vaginas. This condition can affect pregnancy in various ways, but many women with this condition have successful pregnancies.


Considerations for Pregnancy with One Kidney
1. Kidney Function: The most crucial factor for women with a single kidney is the health and function of that kidney. If the remaining kidney is functioning well, the woman can generally conceive and carry a pregnancy to term. Regular monitoring of kidney function through blood tests and urine analysis is essential. Women should work closely with their nephrologist to ensure that their kidney health is stable before attempting to conceive.

2. Potential Risks: Women with a single kidney may face increased risks during pregnancy, including hypertension (high blood pressure) and proteinuria (excess protein in urine). These conditions can lead to complications such as preeclampsia, which poses risks to both the mother and the fetus. Therefore, it is vital to have a comprehensive preconception evaluation and ongoing prenatal care.

3. Nutritional Considerations: Maintaining a healthy diet is crucial for women with one kidney. This includes adequate hydration, a balanced intake of nutrients, and possibly limiting sodium and protein intake, depending on the kidney's function. Consulting with a nutritionist who specializes in renal health can be beneficial.


Uterus Didelphys and Pregnancy
1. Pregnancy Outcomes: Women with uterus didelphys can have successful pregnancies, but they may be at a higher risk for certain complications, such as preterm labor, miscarriage, and abnormal fetal positioning. The presence of two uteri can sometimes lead to complications if one uterus is less developed or if there are structural abnormalities.

2. Monitoring and Care: It is essential for women with uterus didelphys to receive specialized prenatal care. This may involve more frequent ultrasounds to monitor fetal growth and development, as well as the health of both uteri. A multidisciplinary team, including obstetricians familiar with uterine anomalies, can provide the best care.

3. Genetic Considerations: Regarding the concerns about congenital conditions in children, such as heart defects or kidney anomalies, it is important to understand that while some congenital conditions can have a genetic component, many are sporadic and not directly inherited. However, if there is a family history of congenital anomalies, genetic counseling may be advisable to assess risks and provide guidance.


Conclusion
In summary, women with one kidney and uterus didelphys can safely get pregnant, provided they have good kidney function and receive appropriate prenatal care. It is crucial to work closely with healthcare providers to monitor both kidney health and pregnancy progress. Regular check-ups, a healthy lifestyle, and a supportive medical team can help ensure a successful pregnancy outcome. If there are concerns about genetic risks or specific congenital conditions, consulting with a genetic counselor can provide valuable insights and support.
