Overview
Struvite kidney stones are a type of kidney stone that is composed of magnesium, ammonium, and phosphate. These stones form when bacteria in the urinary tract produce ammonia, which reacts with magnesium and phosphate in the urine, forming crystals that can grow into stones.
While these stones have traditionally been more common in women, recent studies have shown that they are on the rise in children. It increases due to the rise in antibiotic-resistant urinary tract infections, which can lead to chronic infections that increase the risk of struvite stone formation. Parents should be aware of the signs and symptoms of struvite kidney stones in children and seek medical attention if they suspect their child may be affected.
Signs and Symptoms in Children
Here are some of the signs and Struvite Stone symptoms that parents should watch out for:
-
- Pain: The stones can cause pain in the back, side, and lower abdomen. This discomfort might be intense or subtle, and it may appear and go.
- Blood in the urine: The stones can cause bleeding in the urinary tract and might be visible in the urine.
- Frequent urination: Children might have the urgency to urinate more frequently than usual or may experience a sudden urge to urinate.
- Nausea and vomiting: In some cases, stones can cause nausea and vomiting.
- Fever: Children may develop a fever if a bacterial infection causes struvite stones.
Causes of Struvite Stones
Here are some Struvite Stone Causes to look out for:
-
- Urinary tract infections (UTIs) are the primary cause of struvite stones in children. Bacteria such as Proteus and Klebsiella produce ammonia, raising urine pH and promoting struvite crystal formation. The bacteria produce ammonia as a waste product that can make the urine more alkaline or less acidic. When the urine becomes excessively alkaline, it leads to struvite stone formation.
- Children with conditions obstructing the urinary tract, such as vesicoureteral reflux or urethral strictures, are at a higher risk of stones due to urine stasis and bacterial overgrowth.
- Genetics may play a role in stone formation in some children, as inherited metabolic disorders can lead to elevated levels of certain minerals in the urine that can form crystals.
- Dehydration can increase the risk of struvite stone formation by concentrating urine and making it more alkaline, promoting crystal formation.
- Diet can influence struvite stone formation in children, as consuming foods high in certain minerals like calcium, magnesium, and phosphorus, such as milk and dairy products, leafy vegetables, fish bones, etc., can increase the likelihood of crystal formation.
- Children who have undergone urinary tract surgery, such as a ureteral reimplantation or bladder augmentation, may be at increased risk of developing struvite stones due to scar tissue and altered urinary flow.
Diagnosis of Struvite Stones
The diagnosis of Struvite stones might get done in the following ways:
-
- Diagnosis of struvite stones in children involves a combination of medical history and imaging tests.
- Ultrasound is often the first-line imaging modality for diagnosing struvite stones in children.
- Other imaging tests, such as X-rays, confirm the diagnosis.
- Blood tests assess kidney function and detect any underlying medical conditions.
- A urinalysis can help identify the presence of bacteria or other substances that may contribute to stone formation.
- Sometimes, a 24-hour urine collection may be necessary to evaluate urinary stone risk factors.
Treatment for Struvite Stones
Now let’s look at the Struvite Stone Treatment Options:
-
- Antibiotic therapy: Antibiotic therapy is an important treatment option for struvite stones in children. This treatment option can help to eliminate the bacterial infection that often causes struvite stones to form in the first place. It can also prevent the recurrence of stones by eliminating any remaining bacteria.
- Extracorporeal shock wave lithotripsy (ESWL): ESWL is a non-invasive treatment option that uses shock waves to break up struvite stones into smaller pieces that can be passed more quickly through the urinary tract. This treatment option is often used for children with larger or more complex struvite stones.
- Percutaneous nephrolithotomy (PCNL): PCNL is a minimally invasive surgical procedure that involves making a small incision in the back to remove larger struvite stones. This treatment option is typically used for children with larger or more complex stones that cannot be treated with ESWL.
- Ureteroscopy: Ureteroscopy is a minimally invasive surgical procedure that involves inserting a small camera through the urethra and into the urinary tract to locate and remove small stones. This treatment option is often used for children with smaller or less complex struvite stones.
Prevention Methods
A few Struvite Stone prevention methods can be to:
-
- Encourage children to drink plenty of water and stay hydrated.
- Teach children proper hygiene practices, including wiping from front to back after using the toilet. This prevents bacteria from spreading.
- Ensure that children empty their bladders when they urinate. It helps in reducing the amount of urine that remains in the bladder.
- Avoid giving children foods and drinks that can contribute to the formation of struvite stones, such as carbonated beverages, processed foods, and high amounts of animal protein.
- If a child has a history of urinary tract infections or struvite stone formation, consider consulting with a pediatric urologist or nephrologist for further evaluation and treatment.

When to Consult a Doctor?
It is important to consult a hyponatremia doctor if you are experiencing any of the symptoms associated with this condition. These include confusion, fatigue, headaches, muscle cramps or spasms and nausea. In addition, if your electrolyte levels have recently changed due to an illness such as diarrhoea or vomiting, seeking medical advice from a qualified healthcare professional is important.

Conclusion
In conclusion, preventing the formation of struvite stones is crucial for maintaining optimal urinary tract health. Furthermore, seeking medical attention at the earliest signs of urinary tract issues can help prevent the development of more serious complications.
