What Are Struvite Stones
Struvite stones are a type of kidney stone that form mainly due to urinary tract infections (UTIs).
When bacteria enter the urinary tract, they cause an infection. These bacteria can easily reach the bladder or urethra and create an infection there.
They are made of:
- Magnesium
- Ammonium
- Phosphate
These stones grow very quickly and can become large in a short time, sometimes forming a “staghorn” shape that fills the kidney.
This is very harmful for the kidneys. If it is not treated properly, it can lead to serious problems.
Why Are Struvite Stones More Common in Women?
Women are more likely to get struvite stones because:
- Women get UTIs more often than men
In women, the urethra is very short, which allows bacteria to easily reach the bladder.
– Due to shorter urethra
– Bacteria reach the bladder more easily
- Recurrent or untreated UTIs
– Repeated infections create the perfect environment for struvite stones to form. - Certain bacteria common in women’s UTIs produce an enzyme called urease, which:
- Breaks down urea
- Increases urine pH (makes it alkaline)
- Leads to formation of struvite stones
How Do Struvite Stones Form?
- UTI occurs
- Bacteria (like Proteus, Klebsiella, Pseudomonas) release urease
- Urine becomes highly alkaline
- Magnesium + ammonium + phosphate combine
- Stones form rapidly and grow large
Symptoms of Struvite Stones
Repeated UTIs
Whenever a woman goes to urinate, if she feels a burning sensation during or after urination, it can be considered a symptom. However, this should happen repeatedly. Sometimes it may occur once in a while, which is normal, but if it continues, it is important to consult a doctor immediately.
If you feel the need to urinate again and again, or if you feel like urine is coming frequently, this is also a symptom. Along with that, if the urine becomes very foul-smelling—stronger than before—this can also be a symptom. In such cases, it is important to consult a doctor immediately.
- Burning during urination
- Frequent urge to urinate
- Cloudy or foul-smelling urine
Flank or back pain
If there is an infection, then during urination or even after urination it can cause a lot of pain. This pain often affects the lower back and the sides of the back.Pain near the lower back or sides.
Fever and chills
Because infection is present with the stone.
Blood in urine
When blood starts to appear in the urine while urinating, the color of the urine will automatically begin to change.Pink, red, or brownish urine.
Nausea and vomiting
During this time, the person will feel like vomiting again and again. They will not feel like eating, and there will also be mild pain in the stomach.
Sudden severe pain if the stone moves
Although struvite stones are often large, some parts can break off and cause intense pain.
Struvite stones can lead to:
- Kidney damage
- Chronic infections
- Blockage in the kidney
- Loss of kidney function
- Sepsis (life-threatening infection)
That is why early treatment is very important.
Treatment for Struvite Stones
Treatment aims to remove the stone and cure the infection.
1. Antibiotics
To treat the underlying UTI.
2. Surgical Removal (often required)
Because these stones grow large, they usually do not pass on their own.
Common procedures:
- PCNL (Percutaneous Nephrolithotomy) – Most common
- Ureteroscopy
- Shockwave Lithotripsy (SWL) (less effective for large stones)
3. Urease Inhibitors (in some cases)
To prevent stone regrowth.
Prevention – Especially Important for Women
1. Treat UTIs immediately
Avoid delaying treatment.
2. Drink plenty of water
Helps flush bacteria and reduce stone formation.
3. Maintain proper hygiene
Reduces chances of bacterial infections.
4. Avoid unnecessary antibiotics
To prevent resistant infections.
5. Regular follow-ups
If someone has had struvite stones once, monitoring is essential to prevent recurrence.
