Physiological changes that cause kidney stones in pregnant women
- Bodily changes affect the urinary tract and increase the risk for kidney stone formation.
- Position and the growing size of the uterus tend to restrict the flow of the urine. Thus, too often urine is retained in the kidneys and the bladder. This can result in the development of stones in the urinary tract.
- If a pregnant female frequently catches urinary infections, she is more prone to kidney stones.

Diagnosis of kidney stones during pregnancy
Urolithiasis in pregnancy is often a diagnostic challenge. Approximately 80-90% of urinary stones are diagnosed after the first trimester completes. Here are various ways to diagnose kidney stones during the pregnancy:
- Urine Culture: A laboratory assessment of urine culture will confirm the infection. Blood work can check the kidney function and increased serum calcium requires investigation.
- Radiological diagnosis of kidney stones: It includes magnetic resonance imaging, the risks from radiation are dependent on fetus age. Obtaining the imaging with the lower dose to treat kidney stones is done in some cases. X-rays are absolutely contraindicated as they are risky to the fetus.
- Ultrasonography for kidney stones: This is the first option for diagnosing kidney stones present in pregnant women. Only specialists can perform the procedure. However, ultrasound does not always show the presence of stones.
- CT scanning: If the symptoms of kidney stones persist and they are causing complex problems, then CT scanning used for a pregnant woman.
- Nuclear renography: A radioisotope is injected into a vein which allows the radiologist to look at the kidneys. Nuclear renography allows a radiologist to clearly visualize the kidneys and check their functioning.
How to get rid of kidney stones while pregnant?
Let’s check out the kidney stone treatment during pregnancy.
Conservative management of urinary stone in pregnancy
The doctor advises the patient for bed rest. The patient should take proper fluid intake and medications to manage the kidney stone symptoms. Most of the stones that are up to 4mm in size can pass normally with high fluid consumption and other dietary suggestions by the doctor. However, stones of size 5-6mm in size do not easily pass on their own through the urinary tract and have high chances of getting stuck in the ureter or urethra. If this happens, surgical intervention becomes necessary for the patient.
Safe surgical treatment for kidney stones during pregnancy
Any type of manipulation in the pelvis, bladder, or ureter could result in premature labor or life-threatening complications for the fetus. That is why any major surgeries are avoided while pregnant. The only safe and minimally invasive surgery is ureteroscopy for pregnant women.
URS (Ureteroscopy)
URS is the recommended method for pregnant women when it is necessary to remove the kidney stone. Holmium is used in ureteroscopy to break down kidney stones. URS is used as an alternative to ESWL in pregnant women.
It is a minimally invasive procedure to get rid of kidney stones. There are no stitches involved in the procedure of ureteroscopy with laser lithotripsy. The laser beam directly acts upon the kidney stones and crushes them down to pass along with the urine. This modern treatment of kidney stones does not require the patient to remain admitted to the hospital for a long time. The patient recovery fully within3-5 days. Hence, it is an absolutely safe treatment for kidney stones.
Kidney stone surgeries that are safe only after pregnancy are:
- Stenting
A stent is placed in the ureter. The tube passes the urine which lessens the burden on the contraction of the urinary tract. The tube won’t be removed till the end of pregnancy. This decreases the chances of kidney stones obstructing the ureter and causing pain. Stenting for kidney stones is a conventional surgical procedure that is invasive and the recovery period is long and discomfort for the patient.
- ESWL (Extracorporeal Shock Wave Lithotripsy)
ESWL uses ultrasonic pulses called shockwaves to break the stones. This surgery is not performed during pregnancy as it can cause fetal damage and death. But, shockwave lithotripsy is highly recommended for non-pregnant women to treat the complicated kidney stones.
PCNL (Percutaneous Nephrolithotomy)
In PCNL, an access tract is created in the kidney's collecting system. PCNL's safety makes it a good treatment option for non-pregnant women. However, PCNL is not recommended during pregnancy. The major reasons to avoid PCNL during pregnancy are because it involves anesthesia and prone position. The prone position is dangerous for a pregnant woman as it requires the patient to lie down on the stomach. Hence, PCNL cannot be carried out in pregnant women to treat kidney stones.
