Do you often wonder what kidney stones are or how they form? Well, this blog will discuss it in detail. Kidney stones form when minerals and salts in the urine accumulate and create deposits in the kidneys. They can vary in size, ranging from tiny particles to larger stones, depending on factors like composition, duration, and rate of mineral buildup. While they are often manageable, untreated kidney stones can lead to severe pain and other complications. A urology expert from Sarjapur Road, Bangalore, discusses in detail all you need to know about kidney stones, including the common symptoms of kidney stones, their causes, management, and prevention.
Synopsis
How are kidney stones formed?
Understanding the causes of kidney stone formation can help you reduce your risk. These stones form due to an imbalance of substances in the urine, leading to crystallisation.
Here are some common causes:
-
Dehydration: Insufficient fluid intake concentrates minerals in the urine, increasing the likelihood of stone formation.
-
Dietary Factors: High consumption of oxalate-rich foods like spinach, nuts, chocolate, and beets can raise the risk.
-
High Salt Intake: Excessive salt can increase calcium levels in the urine, contributing to stone formation.
-
Obesity and Diabetes: Metabolic changes associated with obesity and diabetes can increase the risk of stones.
-
Genetic Predisposition: A family history of kidney stones can increase the risk, as some individuals inherit a predisposition to stone formation.
-
Digestive Diseases: Conditions like inflammatory bowel disease or gastric bypass surgery can increase oxalate absorption.
-
Certain Medications: Some drugs, including diuretics and calcium-based antacids, can raise the risk of stone formation.
What are common symptoms of kidney stones?
Complications can be reduced if you identify kidney stone symptoms early. Symptoms may depend greatly upon the size of the stone, its location within the kidney or urinary tract, and the degree to which it obstructs urine passage. Here are some common symptoms:
-
Severe Pain: Severe cramping pain in the lower back, side, or groin can increase in intensity as the stone progresses down the urinary tract.
-
Pain During Urination: Sharp or burning discomfort while urinating may indicate that the stone has migrated to the ureter or bladder, according to different experiences.
-
Blood in Urine: If the stone travels down the urinary passageway, it can irritate the lining of the urinary tract, causing inflammation and injury. This may result in haematuria or pink, red, or brown urine.
-
Frequent Urination: A frequent urge to urinate with small and frequent voids may indicate that the stone is moving toward the bladder.
-
Nausea and Vomiting: The severe pain can trigger nausea and vomiting, particularly if the stone causes a blockage.
-
Fever and Chills: If the stone is obstructive and has caused a blockage of the urinary tract, it may lead to urinary retention and urinary tract infection, eventually causing fever and chills.
-
Cloudy or Foul-Smelling Urine: This can result from an infection accompanying the stone.
What are the treatment options for kidney stones?
Kidney stone treatment options depend on the size and location of the stone and the severity of symptoms. Kidney specialist in Bangalore often suggest the following options for effective management of kidney stones:
-
Increased Fluid Intake: Drinking plenty of water naturally helps flush out small stones.
-
Pain Management: Over-the-counter pain relievers like paracetamol or tramadol can help manage discomfort.
-
Medical Procedures: Techniques like extracorporeal shock wave lithotripsy (ESWL), in which sound waves break up larger stones which eventually pass through the urine.
-
Ureteroscopy: Using a thin, flexible scope to remove or break the stones in the ureter or kidney.
-
Percutaneous Nephrolithotomy (PCNL): A minimally invasive surgery to remove large stones directly from the kidney.
-
Medication: Alpha-blockers can relax the ureter muscles, helping stones pass more easily.
-
Preventive Measures: Diet changes, increased hydration, and medication can prevent recurrence.
What happens if kidney stones are left untreated?
Kidney stones, if left untreated, can lead to several serious health complications. Here are some potential complications:
-
Severe Pain and Discomfort: Kidney stones can cause intense, sharp pain as they move through the urinary tract, often radiating from the lower back to the groin. This pain can disrupt daily activities and significantly impact the quality of life.
-
Urinary Tract Infections (UTIs): Stones can block the normal flow of urine, creating a favourable environment for bacterial growth. This can lead to frequent or painful urination, cloudy urine, and a persistent urge to urinate.
-
Kidney Damage: Persistent blockage can lead to hydronephrosis, in which the kidneys swell due to urine buildup. If not treated promptly, this can cause long-term kidney damage.
-
Sepsis: In rare cases, if a kidney stone causes a severe infection, it can lead to sepsis, a life-threatening condition where the body's response to infection causes widespread inflammation and organ failure.
-
Blood in Urine (Haematuria): The rough edges of a kidney stone can irritate the urinary tract, causing blood to appear in the urine, which may be pink, red, or brown.
How to Prevent Kidney Stones?
-
Stay Hydrated - Hydration is the golden rule to prevent kidney stones. Generally, it is recommended to drink about 2.5 to 3 litres or 10-12 glasses of water in a day. However, the water requirement may vary in each individual based on their body requirement, physical activity, and weather conditions. You should always aim for a clear or light-yellow urine, which is an indication of adequate hydration.
-
Limit Sodium Intake - Avoid consumption of processed and packaged foods which have high sodium content. Excessive sodium intake results in higher calcium concentration in the urine and an increased risk of kidney stones. Avoid processed and packaged foods
-
Monitor your Protein Intake - Reduce intake of the proteins that can increase the uric acid levels in the body. Choose lean meat over red meat. Include more plant-based proteins such as lentils, legumes, and tofu in your diet.
-
Include Adequate Calcium in Your Diet – Low calcium intake is proven to increase the risk of kidney stones. Include calcium-rich foods such as milk, paneer, and yoghurt in your regular diet. However, unless prescribed by your healthcare provider, do not take calcium supplements.
-
Avoid Carbonated Drinks – Sodas, colas, and other sugary and fizzy drinks usually contain phosphoric acid, which alters the urine composition, increasing the risk of kidney stones.
-
Watch Your Weight – Overweight and obesity increase the risk of metabolic syndrome, which is linked to a higher risk of kidney stones. Maintaining a healthy weight with a balanced diet and regular physical activity can help lower the risk of kidney stones.
Conclusion
Kidney stones can be excruciating and disruptive, but with the proper knowledge and proactive measures, you can reduce your risk and manage symptoms effectively. If you are experiencing any of the symptoms indicative of kidney stones, it is recommended to consult experienced urologists in Manipal Hospital, Sarjapur, Bangalore for timely diagnosis and appropriate treatment.
FAQ's
Kidney stones form when minerals and salts in urine crystallise and clump together, often due to dehydration, high salt intake, or genetic predisposition. Other risk factors include obesity, medical conditions like diabetes, and diets high in oxalates or animal protein. Proper hydration and balanced nutrition can reduce the risk of stone formation.
Kidney stones are diagnosed using imaging tests like CT scans, ultrasounds, X-rays, and urine and blood tests to detect mineral imbalances. Early detection helps identify the size and location of the stone, guiding treatment options and preventing complications. In some cases, further metabolic testing may be needed for recurrent stones.
Smaller kidney stones often pass naturally with increased fluid intake, pain management, and supportive care. However, larger stones may require medical intervention, such as extracorporeal shock wave lithotripsy (ESWL), ureteroscopy, or surgical removal. Early medical evaluation can help determine the best approach for stone management.
Preventing kidney stones involves staying well-hydrated, reducing salt and oxalate-rich foods, maintaining a healthy weight, and moderating protein intake. Regular checkups can help identify risk factors and prevent recurrence. Specific dietary adjustments, like reducing sodium and increasing citrate-rich foods, can also minimize stone formation risk.
A family history of kidney stones can increase your risk, as certain genetic conditions make individuals more prone to forming stones. Inherited disorders like cystinuria and renal tubular acidosis can significantly raise the likelihood of stone formation. Genetic counselling and preventive lifestyle changes can help reduce this risk.
