kidney Stone: Symptoms, Causes, Treatment, Diagnosis & Stages

Kidney stones are hard deposits that form in the kidneys. They comprise minerals and salts that are usually present in the urine. Kidney stones can vary in size from a grain of sand to a golf ball. The incidence of kidney stones is about 12% worldwide. The prevalence is higher in men than in women and increases with age.

The incidence of kidney stones in India is also about 12%. The prevalence is higher in northern India, where it is 15%. This higher prevalence is likely due to the hot and dry climate promoting dehydration.

Some studies that have looked at the incidence of kidney stones in India:

The study "Risk Factors of Incident Kidney Stones in Indian Adults: A Hospital-Based Cross-Sectional Study" (2013) found that the prevalence of kidney stones in Indian adults was 11.8%. The risk factors for kidney stones were male gender, family history of kidney stones, high blood pressure, diabetes, obesity, and low fluid intake.

Doctors can classify kidney stones on two parameters: 

• Composition
• Size

Composition 

• Calcium oxalate stones: These are the most common type of kidney stones, accounting for about 80% of all cases. They form when calcium combines with oxalate in the urine to create solid crystals.
• Calcium phosphate stones: These stones are less common than calcium oxalate stones, making up 10-15% of cases. They form when calcium combines with phosphate in the urine to create crystals.
• Uric acid stones: Uric acid stones are responsible for 5-10% of kidney stone cases. They develop when there is an excess of uric acid in the urine, often associated with conditions like gout or a diet high in purines.
• Struvite stones: Struvite stones comprise around 10% of cases and typically occur due to urinary tract infections (UTIs). They can grow large and quickly and are composed of magnesium, ammonium, and phosphate.
• Cystine stones: Cystine stones are rare, accounting for less than 1% of kidney stones. They form when an inherited disorder causes excessive cystine (an amino acid) to leak into the urine.
• Mixed stones: Sometimes, kidney stones can be composed of a combination of minerals, such as calcium oxalate mixed with calcium phosphate or uric acid mixed with calcium oxalate.
• Other rare stones: In sporadic cases, kidney stones can be composed of other substances, such as xanthine, 2,8-dihydroxyadenine, or drugs like indinavir (a medication used to treat HIV).

Size 

• Small kidney stones (Less than 5 mm): These tiny kidney stones measure under 5 millimeters. They can be as small as grains of sand and may quietly exit the urinary tract with enough hydration and over-the-counter pain relief.
• Medium-sized kidney stones (5-10 mm): They fall into the 5 to 10-millimeter range, and these medium-sized kidney stones are more common. They often require a watchful eye and extra fluids to encourage passage, sometimes accompanied by prescribed medications to alleviate discomfort.
• Large kidney stones (More than 10 mm): Large kidney stones exceed 10 millimeters and can be formidable. These sizable intruders are less likely to leave voluntarily. They typically demand medical attention, potentially involving surgical procedures, shock wave treatments, or other specialized interventions to remove or fragment them.
• Staghorn calculi: Staghorn calculi are the heavyweight contenders among kidney stones. They are notorious for occupying a significant portion of the kidney's complex internal structures. Removing these tenacious occupants necessitates intricate surgical approaches due to their size and complicated growth patterns.

One may experience a range of symptoms due to kidney stones depending on the size of the stone, its location, and the physical status of the patient.

The following are some common symptoms of kidney stones are:

• Severe flank pain: Kidney stones commonly cause excruciating pain in the back or side, known as flank pain, which can radiate to the lower abdomen and groin.
• Frequent urination: Some individuals experience an increased frequency of urination, often accompanied by a strong urge to urinate.
• Hematuria (blood in urine): Hematuria, or the presence of blood in the urine, can occur, giving the urine a pink, red, or brownish color.
• Painful urination: Passing urine may be painful or uncomfortable, with a burning sensation.
• Nausea and vomiting: Kidney stone pain can trigger feelings of nausea and may lead to vomiting in some cases.
• Urinary urgency: An urgent need to urinate can be a distressing symptom associated with kidney stones.
• Cloudy or foul-smelling urine: Kidney stones may cause changes in urine appearance, such as cloudiness or an unusual odor.
• Difficulty passing urine: As a stone moves through the urinary tract, it can obstruct urine flow, causing difficulty emptying the bladder fully.
• Fever and chills: Kidney stones can sometimes lead to fever and chills, indicating a possible infection associated with the stone.
• Renal colic: This term refers to intense, crampy pain as the stone moves through the urinary tract, often causing restlessness and discomfort.
• Groin pain: Kidney stone pain can radiate into the groin area, contributing to discomfort and making it challenging to pinpoint the exact source of pain.
• Painful fluctuations: The pain associated with kidney stones can vary in intensity, with intermittent bouts of severe pain interspersed with periods of relative comfort.
• Abdominal discomfort: Some individuals may experience generalized abdominal discomfort, which can be mistaken for gastrointestinal issues.
• Cold sweats: Kidney stone pain can trigger cold sweats, particularly during intense pain episodes.
• Restlessness: The discomfort and pain from kidney stones may cause restlessness and difficulty finding a comfortable position.

The following are some of the common causes of kidney stones are: 

• Dietary factors: An imbalanced diet high in animal protein, sodium, and sugar promotes the concentration of calcium and oxalate in the urine, providing the raw materials for stone formation.
• Dehydration: Inadequate fluid intake reduces urine volume, allowing minerals like calcium, oxalate, and uric acid to become more concentrated and form crystals, which can eventually merge into stones.
• Family history: Genetic factors can influence how the kidneys handle minerals and salts, potentially leading to an increased risk of stone formation, as seen in familial patterns.
• Metabolic conditions: Conditions like hyperparathyroidism disrupt the regulation of calcium in the body, leading to higher levels of calcium in the urine, a crucial step in stone development.
• Obesity: Excess body fat increases insulin resistance, affecting the body's handling of calcium and uric acid, increasing their excretion into the urine and promoting stone formation.
• Certain medications: Diuretics, for example, can lead to increased urinary excretion of calcium and magnesium, contributing to stone formation through elevated urine concentrations of stone-forming minerals.
• Urinary tract infections (UTIs): Specific bacteria, such as Proteus species, produce urease enzymes that hydrolyze urea into ammonia, leading to an alkaline urine environment conducive to struvite stone formation.
• Gout has elevated uric acid levels, which can lead to the oversaturation of uric acid in the urine, resulting in crystal formation and uric acid stone development.
• Inflammatory bowel disease (IBD): Chronic inflammation in the digestive tract can disrupt the absorption of nutrients, leading to increased oxalate absorption and the potential for calcium oxalate stone formation.
• Excessive vitamin D or calcium supplementation: Overconsumption of these supplements can lead to hypercalcemia, increasing calcium excretion in urine and elevating the risk of calcium-based stone formation.
• Sedentary lifestyle: Physical inactivity can contribute to obesity and insulin resistance, disrupting the balance of calcium and uric acid metabolism and predisposing individuals to stone formation.
• Geographical location: Hot and arid climates can lead to increased perspiration, potentially leading to chronic low-level dehydration and an environment conducive to stone crystallization due to concentrated urine.

Some of the most common ways to prevent the occurrence of kidney stones are: 

• Stay hydrated: Drinking ample fluids, particularly water, is paramount in kidney stone prevention. Aim for eight glasses of water daily, or more if you reside in a warm climate or maintain an active lifestyle. Adequate hydration dilutes urine and aids in the removal of stone-forming substances. A 2012 study in "Kidney International" revealed that individuals consuming eight or more daily glasses of water had a lower kidney stone incidence than those drinking less than four glasses.
• Adopt a balanced diet: Prioritize a diet low in sodium while rich in fruits, vegetables, and whole grains. These dietary choices help maintain an alkaline urine environment, reducing the propensity for stone formation. A 2015 study published in "Nutrition Reviews" found that a diet rich in fruits and vegetables correlated with a reduced risk of kidney stones.
• Moderate animal protein: Curtail your animal protein intake, especially if you're prone to calcium oxalate stones. Substituting some animal protein with plant-based sources can mitigate the risk.
• Limit sugary beverages: Avoid sugary drinks, as they can elevate oxalate levels in urine, heightening the risk of kidney stones. Opt for water, unsweetened tea, or coffee as healthier alternatives.
• Manage weight: If you're overweight or obese, shedding even a modest amount of excess weight can significantly decrease your susceptibility to kidney stones, as obesity is a risk factor.
• Medication adherence: If you've experienced kidney stones, follow your doctor's prescribed medications diligently. Some doctors may recommend Potassium citrate, thiazides, or allopurinol to prevent stone recurrence. In 2016, "The American Journal of Clinical Nutrition" published a study demonstrating that potassium citrate supplementation decreased the risk of kidney stone development.

The diagnosis of kidney stones involves a comprehensive process encompassing various medical assessments and imaging techniques to accurately identify the presence, location, and characteristics of these mineral deposits within the urinary tract.

• Medical history and symptoms assessment: The initial step in diagnosing kidney stones involves taking a comprehensive medical history and evaluating the patient's symptoms. Physicians inquire about symptoms like flank pain, hematuria, and urinary urgency, gathering crucial information to guide further testing.
• Physical examination: A thorough physical examination helps healthcare providers identify signs of kidney stone-related distress, such as tenderness or pain upon palpation of the lower back or abdomen.
• Urinalysis: Urinalysis involves examining a urine sample for blood, crystals, or abnormal levels of minerals like calcium, oxalate, or uric acid, which can signal kidney stone formation.
• Imaging studies: Various imaging techniques are employed for kidney stone diagnosis, including:
• Ultrasound: Ultrasound employs sound waves to create images of the kidneys and urinary tract, often used for initial screening due to its non-invasive nature.
• CT scan (Computed Tomography): CT scans offer detailed cross-sectional images of the urinary tract, facilitating precise identification of stone location, size, and obstruction.
• Intravenous pyelogram (IVP): IVP involves injecting a contrast dye intravenously and tracking its passage through the urinary system via X-rays. This method helps visualize stones and assess urinary flow.
• Stone analysis: Analyzing a passed or surgically removed stone can provide valuable information about its composition, aiding in treatment and prevention strategies.
• Blood tests: Blood tests, such as serum creatinine and electrolyte levels, may be conducted to assess kidney function and determine if kidney stones have led to any complications.
• Pain assessment: The evaluation of the location, nature, and intensity of pain experienced by the patient can offer valuable diagnostic clues, as different stone types and locations often elicit distinct pain patterns.
• Infection testing: If signs of infection, such as fever or chills, are present, your doctor may prescribe blood and urine cultures to identify the causative organism.
• Metabolic evaluation: For recurrent stone formers, the healthcare provider may conduct a metabolic evaluation to assess underlying conditions contributing to stone formation, including urinary pH, calcium, oxalate, and citrate levels.

Kidney stones typically progress through several stages during their formation and passage. These stages help describe the lifecycle of a kidney stone, from its initial development to its eventual elimination or management, including:

• Formation (nucleation): The process initiates as specific substances in the urine combine and crystallize, creating minute particles within the kidney. These microscopic crystals serve as the foundational building blocks for kidney stone development.
• Growth (crystal aggregation): Over time, these crystals tend to adhere and accumulate, resulting in the enlargement of these solid masses. The rate of gain varies depending on factors such as urine composition and the presence of promotive or inhibitory elements.
• Stone formation (aggregation into stones): As these crystals continue to coalesce and amass, they eventually merge into compact kidney stones, manifesting in diverse sizes and compositions, such as calcium oxalate, calcium phosphate, uric acid, or struvite stones.
• Migration (renal colic): Once a kidney stone surpasses a specific size threshold, it may commence movement within the kidney or traverse down the narrow ureter, thereby eliciting intense, cramp-like pain recognized as renal colic.
• Obstruction and pain: Should the stone impede urinary flow, it can cause augmented pressure, discomfort, and pain, with the severity contingent on the stone's location within the urinary system, thereby giving rise to various symptoms.
• Complications: Kidney stones carry the potential for complications like urinary tract infections (UTIs), hydronephrosis (kidney swelling due to urine obstruction), and plausible renal tissue damage, warranting timely medical attention if left unaddressed.
• Passage or intervention: Depending on their dimensions and position, kidney stones may either navigate the urinary tract independently or necessitate medical procedures like lithotripsy (shock wave therapy), ureteroscopy, or percutaneous nephrolithotomy to facilitate extraction.

The management of kidney stones depends on the size of the stone and the person's physical status. Some of the treatment modalities for kidney stones are:

• Hydration: Adequate fluid intake is a fundamental aspect of kidney stone management. Consistently maintaining proper hydration helps dilute urine, reducing the concentration of stone-forming substances and facilitating their passage.
• Pain management: Pain relief is essential during kidney stone episodes. Over-the-counter pain medications, nonsteroidal anti-inflammatory drugs (NSAIDs), or prescribed pain relievers can alleviate discomfort.
• Observation and monitoring: Smaller kidney stones (typically less than 5mm) may pass spontaneously with increased fluid intake and pain management. Close monitoring with periodic imaging ensures their progress.
• Medical expulsion therapy: Alpha-blocker medications may help relax the ureter's muscles, aiding the stone's passage. This approach is more suitable for stones located in the lower ureter.
• Lithotripsy (ESWL): Extracorporeal Shock Wave Lithotripsy (ESWL) employs shock waves to break down stones into smaller fragments, facilitating their natural passage.
• Ureteroscopy (URS): Ureteroscopy involves the insertion of a thin, flexible tube into the ureter to visualize and remove or fragment stones using laser or mechanical devices.
• Percutaneous nephrolithotomy (PCNL): For more extensive or complex stones, PCNL is a minimally invasive procedure with a small incision to access and remove the stone from the kidney.
• Surgical removal: In some instances, particularly with large or complicated stones, open surgery may be necessary to extract the stone directly from the kidney or urinary tract.
• Stone analysis: Analyzing the composition of a passed or surgically removed stone helps identify its type and informs targeted prevention strategies.
• Metabolic evaluation: A comprehensive metabolic evaluation may help to assess underlying factors contributing to stone formation for recurrent stone formers, allowing for tailored dietary and medication recommendations.
• Dietary modifications: Dietary changes may include reducing sodium and animal protein intake, limiting foods high in oxalate, and increasing consumption of fruits and vegetables to promote urine alkalinity.
• Hydration: Adequate fluid intake is paramount. Drinking plenty of water, typically aiming for at least 8 to 10 cups daily, helps dilute urine, reducing the concentration of stone-forming minerals.
• Sodium reduction: Cutting back on high-sodium foods, like processed snacks and canned soups, helps lower the risk of calcium-based stone formation. Reduced sodium intake decreases the amount of calcium excreted in the urine.
• Limiting animal protein: Moderation in consuming animal proteins such as meat, poultry, and fish can be beneficial, as excessive protein intake can increase the excretion of calcium and uric acid in the urine, contributing to stone formation.
• Calcium consumption: Paradoxically, maintaining an adequate calcium intake from dietary sources (about 1,000-1,200 milligrams per day) can prevent oxalate absorption in the intestines, thus reducing the risk of calcium oxalate stones.
• Oxalate management: Be mindful of foods high in oxalate, including spinach, beets, nuts, and chocolate. While these foods offer nutritional benefits, limiting their consumption can reduce oxalate levels in urine.
• Moderation in vitamin C: Excessive vitamin C intake can lead to the formation of oxalate crystals. It's advisable to obtain vitamin C from natural food sources rather than supplements.
• Alkalinizing diet: Incorporating fruits and vegetables rich in citrate, such as citrus fruits, can help alkalinize urine, inhibiting the formation of calcium stones.
• Limiting caffeine and alcohol: Reducing caffeine and alcohol consumption can be advantageous, as they can increase urine output and potentially lead to dehydration.
• Portion control: Paying attention to portion sizes can aid in managing calorie intake and body weight, factors that influence stone formation risk.
• Meal planning: Regular, balanced meals can help stabilize blood sugar levels and prevent fluctuations that affect calcium excretion in urine.
• Moderate sugar intake: High sugar consumption can increase the excretion of oxalate in urine. Choosing unsweetened beverages and minimizing sugary snacks is advisable.
• Consultation with a dietitian: For individuals with a history of kidney stones or specific dietary needs, consulting a registered dietitian can be invaluable. They can provide tailored dietary guidance to reduce stone recurrence risk.

The prognosis of kidney stones is favorable. Most of the patients recover fully after the treatment and management of kidney stones. It encompasses:

• Medications: Depending on stone type and underlying conditions, healthcare providers may prescribe thiazides, potassium citrate, or allopurinol to modify urine composition and reduce stone formation risk.
• Regular follow-up: Continuous follow-up appointments are crucial to monitor progress, evaluate treatment effectiveness, and adjust management strategies.
• Lifestyle adjustments: Incorporating regular physical activity and maintaining a healthy body weight are essential in reducing stone recurrence risk.
• Preventive measures: Understanding one's risk factors, adhering to dietary and lifestyle modifications, and staying hydrated are essential preventative measures to minimize the likelihood of future kidney stone formation.
• Favorable outcomes: In many cases, kidney stones have a good prognosis. Smaller stones, particularly those less than 5mm in size, often pass spontaneously and without complications.
• Natural passage: The prognosis is especially promising when a stone moves naturally through the urinary tract without causing obstruction or significant pain. Most individuals experience relief once the stone they expel the stone through urine.
• Prompt intervention: When intervention is required, the prognosis remains positive with timely medical attention. Treatments like lithotripsy, ureteroscopy, or percutaneous nephrolithotomy are highly effective in stone removal.
• Preventive strategies: Following kidney stone management adopting preventive measures, including dietary modifications and hydration, significantly reduces the risk of stone recurrence.
• Complications: In cases where stones lead to complications like infections or kidney damage, prompt treatment is essential. Early intervention can mitigate the risk of long-term complications and support a more favorable prognosis.
• Chronic kidney disease (CKD): In rare instances, severe or recurrent kidney stone episodes can contribute to the development of chronic kidney disease. However, early detection and appropriate management can help mitigate this risk.
• Individual factors: Prognosis can vary based on stone size, composition, and location. Stones causing persistent obstruction or those requiring surgical intervention may have a slightly less favorable prognosis.
• Recurrence risk: The prognosis regarding stone recurrence is generally good when individuals adhere to preventive measures and lifestyle modifications, reducing the likelihood of future stone formation.
• Long-term health: Maintaining overall health through a balanced diet, regular physical activity, and hydration is crucial for preventing kidney stone recurrence and supporting long-term well-being.
• Consultation with a healthcare provider: Consulting a healthcare provider after experiencing kidney stones is advisable. They can provide personalized guidance, monitor stone-related risk factors, and tailor preventive strategies for each patient, ultimately contributing to a favorable prognosis.
