Kidney Stones in Pregnancy: Pregnancy brings several physical and hormonal changes, but certain symptoms should never be ignored. Severe pain in the lower back, discomfort on one side of the abdomen, burning during urination, or blood in the urine could indicate kidney stones. Although this condition can often be managed safely, delayed treatment may increase the risk of complications for both the mother and the developing baby.

Kidney stones during pregnancy require special medical attention because doctors must consider the health of two individuals while deciding on treatment. From diagnosis to medication and surgical procedures, every decision must be made carefully to minimize potential risks.

Why Can Kidney Stones Become a Concern During Pregnancy?

During pregnancy, hormonal changes can affect the urinary system. The growing uterus may also put pressure on the urinary tract, slowing urine drainage and making it more difficult to identify certain urinary problems.

Kidney stones are hard deposits of minerals and salts that develop inside the kidneys. Small stones may pass naturally through urine, while larger stones can become trapped in the urinary tract, causing severe pain or obstruction.

According to Dr. Ajit Kumar, Assistant Professor at Rajiv Gandhi Hospital, managing urinary stones during pregnancy requires additional precautions because treatment decisions must prioritize the safety of both the pregnant woman and her unborn child.

What Are the Common Symptoms of Kidney Stones During Pregnancy?

Kidney stone symptoms can sometimes resemble other pregnancy-related discomforts. However, certain warning signs require immediate medical evaluation.

Common symptoms include:

• Severe pain in the lower back or on one side of the abdomen.

• Pain or a burning sensation while passing urine.

• Blood appearing in the urine.

• Frequent urges to urinate.

• Nausea or vomiting accompanied by intense pain.

• Difficulty passing urine or reduced urine output.

• Fever and chills, particularly when an infection is present.

Not every pregnant woman with these symptoms necessarily has kidney stones. Urinary tract infections and other medical conditions can cause similar problems, making a proper diagnosis essential.

Which Test Is Safest for Detecting Kidney Stones During Pregnancy?

When doctors suspect kidney stones, ultrasound is generally the first imaging test recommended during pregnancy.

Ultrasound uses sound waves rather than ionizing radiation, making it a preferred initial examination for pregnant patients.

The scan helps doctors examine the kidneys and urinary tract for possible stones, swelling, or signs of obstruction.

However, ultrasound may not detect every stone. If the diagnosis remains uncertain, doctors may recommend additional imaging based on the patient's condition and the potential benefits and risks.

Can Kidney Stones Be Treated Without Surgery?

The good news is that not every kidney stone diagnosed during pregnancy requires an operation.

If the stone is relatively small, pain is manageable, kidney function remains stable, and there is no significant blockage or infection, doctors may recommend conservative treatment.

This approach may involve appropriate hydration, pregnancy-safe pain management, observation, and follow-up examinations.

Doctors monitor the patient's condition to determine whether the stone passes naturally or further treatment becomes necessary.

However, pregnant women should never attempt to flush out stones by drinking excessive amounts of water or taking unprescribed medication.

Is It Safe to Take Painkillers During Pregnancy?

Taking painkillers without medical advice can be risky during pregnancy.

Certain medications commonly used to relieve kidney stone pain may not be appropriate at particular stages of pregnancy. For example, nonsteroidal anti-inflammatory drugs (NSAIDs) can pose fetal risks, especially later in pregnancy.

Therefore, doctors select pain-relieving medicines after considering the stage of pregnancy, the severity of symptoms, and the patient's overall health.

Pregnant women should also avoid herbal stone-removal remedies or over-the-counter medicines unless their healthcare professional confirms they are safe.

When Is Surgery Necessary for Kidney Stones During Pregnancy?

Although many cases can be managed without surgery, some situations require urgent medical intervention.

A procedure may become necessary when:

• A kidney stone causes significant urinary obstruction.

• Severe pain continues despite appropriate treatment.

• Kidney function becomes impaired.

• An infection develops behind a blocked urinary tract.

• Conservative treatment fails to improve the condition.

Depending on the situation, doctors may recommend a ureteric stent or nephrostomy tube to allow urine to drain properly.

In selected cases, ureteroscopy may be performed to remove or treat the stone. Specialists decide on the safest approach after assessing the pregnancy and the patient's medical condition.

Can Kidney Stones Harm the Unborn Baby?

Kidney stones do not automatically cause harm to the baby. However, complications associated with untreated stones may create additional pregnancy risks.

Severe urinary obstruction, kidney infection, or persistent illness can increase the likelihood of maternal complications. Some studies have also linked kidney stone episodes during pregnancy with a higher risk of preterm delivery.

The level of risk depends on the severity of the condition, whether an infection is present, and how quickly appropriate treatment begins.

Timely diagnosis and medical care can help reduce these risks.

When Should Pregnant Women Seek Immediate Medical Attention?

Doctors advise pregnant women to seek prompt medical attention if they experience intense or persistent abdominal or back pain, fever, chills, blood in the urine, or difficulty urinating.

Fever combined with suspected kidney stones is particularly concerning, as it may indicate an infection associated with urinary blockage. This situation can become a medical emergency and requires urgent hospital assessment.

Pregnant women experiencing these symptoms should not wait for the pain to disappear naturally.

Final Advice: Do Not Ignore Unusual Pain During Pregnancy

While back pain and abdominal discomfort can occur during a normal pregnancy, severe or unusual symptoms should not automatically be considered harmless.

Kidney stones can often be treated successfully during pregnancy with careful medical supervision. Early diagnosis, suitable medication, and timely intervention when necessary are important for protecting maternal and fetal health.
