Is 7mm Kidney Stone Dangerous? Symptoms, Risks, and Treatment Options

July 22, 2025

Kidney stones are a common urological problem affecting people of all ages. If you or a loved one has been diagnosed with a 7mm kidney stone, it’s natural to feel concerned. But is a 7mm kidney stone dangerous? The answer depends on several factors including its location, symptoms, and whether it’s causing complications.

In this detailed guide from Kolekar Hospital, we explain everything you need to know about 7mm kidney stones their risks, symptoms, diagnosis, treatment options, and when to seek urgent medical help.

What Is a Kidney Stone?

Kidney stones are hard deposits made of minerals and salts that form inside your kidneys. They can vary in size—from as small as a grain of sand to several centimeters in diameter.

Common Causes of Kidney Stones:

  • Low fluid intake (dehydration)
  • High intake of oxalate-rich foods (spinach, nuts, chocolate)
  • High sodium or protein diet
  • Obesity
  • Certain medical conditions (hyperparathyroidism, UTIs)
  • Family history of kidney stones

Is a 7mm Kidney Stone Dangerous?

Yes, a 7mm kidney stone can be dangerous if not managed properly. Stones larger than 5mm are considered moderate to large and may not pass naturally. A 7mm stone is unlikely to pass on its own and often requires medical or surgical intervention.

Why a 7mm Kidney Stone Can Be Dangerous:

FactorRisk
SizeToo large to pass through ureter without assistance
LocationCan block urine flow if stuck in the ureter
PainSevere flank pain due to blockage or inflammation
InfectionRisk of kidney or urinary tract infection
HydronephrosisSwelling of the kidney due to blocked urine
Kidney damageProlonged obstruction can damage kidney function

Symptoms of a 7mm Kidney Stone

While some kidney stones remain asymptomatic, a 7mm stone is more likely to cause noticeable and painful symptoms, especially if it obstructs the urinary tract.

Common Symptoms:

  • Severe back or flank pain, often radiating to the groin
  • Nausea and vomiting
  • Pain during urination
  • Frequent urge to urinate
  • Blood in urine (hematuria)
  • Foul-smelling or cloudy urine
  • Fever and chills (indicating infection)

Can a 7mm Kidney Stone Pass Naturally?

It is rare for a 7mm stone to pass without medical intervention. The chances of spontaneous passage decrease significantly for stones above 5mm.

Stone SizeChance of Natural Passage
Less than 4mm80% or higher
4-6mm50-60%
6-8mm20-30%
Over 8mmRarely pass without treatment

A 7mm kidney stone is likely to get stuck in the ureter, causing obstruction and complications. Hence, timely medical management is crucial.

Diagnosis of a 7mm Kidney Stone

If you’re experiencing symptoms, a urologist at Kolekar Hospital may recommend the following diagnostic tests:

Common Diagnostic Tests:

  • Ultrasound of the abdomen and pelvis
  • Non-contrast CT scan (gold standard)
  • X-ray (KUB)
  • Urinalysis (to detect blood, infection, or crystals)
  • Blood tests (to evaluate kidney function and detect infection)

Treatment Options for a 7mm Kidney Stone

At Kolekar Hospital, we offer a range of advanced and minimally invasive treatments for kidney stones based on the stone’s size, location, symptoms, and overall health of the patient.

1. Medical Management

  • Alpha-blockers (e.g., Tamsulosin) may be prescribed to relax the ureter and facilitate passage.
  • Adequate hydration and pain relief medications are essential.
  • This is generally attempted only if the stone is in the lower ureter and the patient is stable.

Limitations: Medical management is often not effective for a 7mm stone due to its size.

2. Extracorporeal Shock Wave Lithotripsy (ESWL)

What It Is: A non-invasive treatment that uses sound waves to break the stone into smaller fragments.

Best For: Stones in the kidney or upper ureter.

Limitations:

  • May require multiple sessions
  • Less effective for hard or lower ureteric stones

3. Ureteroscopy (URS)

What It Is: A thin scope is passed through the urethra and bladder into the ureter to directly visualize and remove or fragment the stone using a laser.

Best For: Stones located in the middle or lower ureter.

Benefits:

  • Minimally invasive
  • High success rate
  • Can be done as day-care surgery

4. Percutaneous Nephrolithotomy (PCNL)

What It Is: A small incision is made in the back to access the kidney directly and remove the stone.

Best For:

  • Very large or complex kidney stones
  • Stones causing severe blockage or infection

Consideration: Invasive but highly effective when other methods fail.

Risks of Leaving a 7mm Kidney Stone Untreated

Ignoring or delaying treatment for a 7mm kidney stone can lead to serious complications, including:

  • Recurrent infections
  • Hydronephrosis (kidney swelling)
  • Permanent kidney damage
  • Urosepsis (a life-threatening infection)
  • Chronic pain and urinary problems

When to Seek Immediate Medical Help

You should consult a urologist immediately if you experience:

  • Fever with chills (sign of infection)
  • Persistent nausea and vomiting
  • Severe pain unrelieved by medication
  • Inability to urinate
  • Blood in urine
  • Decreased urine output

Emergency care is essential to prevent long-term kidney damage.

Preventing Kidney Stones After Treatment

Once treated, it’s important to prevent future stones through lifestyle modifications and follow-up care.

Prevention Tips:

  • Drink at least 2.5 to 3 liters of water daily
  • Limit sodium and animal protein intake
  • Avoid foods high in oxalates (nuts, spinach, beets)
  • Reduce sugar and cola consumption
  • Maintain a healthy weight
  • Follow your doctor’s dietary advice
  • Regular check-ups and urine analysis as advised

What is the First Sign of Kidney Problems? Early Warning Signs You Shouldn’t Ignore

July 18, 2025

Your kidneys silently work 24/7 to keep your body balanced and healthy. They filter waste, regulate blood pressure, manage fluid levels, and support bone and blood health. When kidney function begins to deteriorate, the early signs can be easy to miss. Understanding what is the first sign of kidney problems can be life-saving.

In this detailed article from Kolekar Hospital, we explore what is the first sign of kidney problems, why it happens, what other early symptoms to look for, and how to protect your kidneys through early diagnosis and prevention.

Understanding the Role of Kidneys

Before diving into what is the first sign of kidney problems, it’s important to understand what kidneys do for the body:

  • Filter waste and toxins from the blood
  • Balance electrolytes like sodium and potassium
  • Regulate blood pressure
  • Control fluid levels
  • Support red blood cell production
  • Maintain bone health

Because kidneys are so vital, even mild dysfunction can lead to serious health issues. That’s why recognizing what is the first sign of kidney problems is critical.

What is the First Sign of Kidney Problems?

Swelling (Edema) is Often the First Noticeable Symptom

When discussing what is the first sign of kidney problems, the most common and visible symptom is persistent swelling, especially in the feet, ankles, face, or hands. This occurs due to the kidneys’ reduced ability to eliminate excess sodium and fluid from the body, leading to fluid retention in tissues.

Why Does Swelling Happen?

  • Damaged kidneys can’t maintain proper sodium-water balance
  • Protein leaks into the urine, reducing blood protein levels
  • Fluid shifts from blood vessels into tissues, causing puffiness

Common Areas Where Swelling Occurs:

  • Under the eyes (especially in the morning)
  • Feet and ankles (worsens during the day)
  • Hands and fingers

Recognizing what is the first sign of kidney problems like swelling can help initiate early tests and treatment, preventing long-term damage.

Other Early Symptoms of Kidney Problems

While swelling is often what is the first sign of kidney problems, several other symptoms may appear early on. Being aware of them improves early diagnosis.

SymptomWhat It Means
Changes in urinationFrequent urination at night, foamy or dark urine, or blood in urine
Fatigue and weaknessToxin buildup and reduced red blood cell count lead to low energy levels
Loss of appetiteWaste accumulation affects digestion and metabolism
Dry and itchy skinPoor kidney function can affect mineral balance, leading to itchy, flaky skin
Nausea and vomitingToxin overload can irritate the stomach
Shortness of breathFluid buildup in lungs or anemia due to reduced kidney hormone production
Trouble concentratingToxins in the bloodstream can impair mental clarity
Metallic taste in mouthWaste buildup can cause a persistent foul or metallic taste

Even if swelling is what is the first sign of kidney problems, other symptoms can follow quickly if left untreated.

Causes of Kidney Problems

To understand what is the first sign of kidney problems, it’s essential to know what causes kidney function to deteriorate in the first place.

1. Diabetes Mellitus

  • High blood sugar damages kidney blood vessels over time
  • Leading cause of chronic kidney disease (CKD)

2. High Blood Pressure

  • Damages the delicate filtering structures inside kidneys

3. Recurrent UTIs

  • Can lead to infection and scarring of kidney tissues

4. Glomerulonephritis

  • Inflammation of kidney filters that can cause protein and blood leakage

5. Polycystic Kidney Disease

  • A genetic disorder that leads to cysts forming in the kidneys

6. Overuse of Certain Medications

  • NSAIDs, antibiotics, and contrast dyes can be nephrotoxic

Avoiding these causes—or managing them proactively—is key once you know what is the first sign of kidney problems to watch for.

How Are Kidney Problems Diagnosed?

If you’re experiencing swelling or other symptoms, here’s how doctors at Kolekar Hospital determine if your kidneys are involved.

1. Blood Tests

  • Creatinine and BUN levels rise when kidneys aren’t functioning well
  • eGFR (Estimated Glomerular Filtration Rate) measures overall kidney function

2. Urine Tests

  • Urinalysis can detect protein, blood, and infections
  • Albumin-to-Creatinine Ratio (ACR) identifies early signs of damage

3. Imaging Tests

  • Ultrasound or CT scan to assess kidney size, shape, and possible blockages

4. Kidney Biopsy

  • A small tissue sample may be taken for detailed lab analysis

If you’ve been wondering what is the first sign of kidney problems, testing these markers provides accurate answers.

When to See a Doctor

Recognizing what is the first sign of kidney problems is only helpful if followed by timely medical evaluation. You should visit a nephrologist if you notice:

  • Swelling around eyes, feet, or hands
  • Unusual changes in urination pattern
  • Feeling unusually tired or breathless
  • Loss of appetite or nausea
  • Skin dryness or itchiness
  • High blood pressure that is hard to control

Prompt consultation ensures early-stage kidney disease can be managed effectively.

Preventing Kidney Problems: What You Can Do

Knowing what is the first sign of kidney problems gives you a head start. Here are preventive steps to protect your kidney health:

Healthy Diet

  • Reduce salt and processed food
  • Eat a balanced diet with fruits and vegetables
  • Limit red meat and high-protein diets if at risk

Hydration

  • Drink plenty of water daily unless advised otherwise
  • Avoid sugary drinks and alcohol

Lifestyle Habits

  • Maintain a healthy weight
  • Quit smoking
  • Exercise regularly (at least 30 mins/day)

Regular Health Checks

  • Monitor blood sugar and blood pressure
  • Get annual urine and blood tests for kidney function
  • Avoid self-medicating with over-the-counter painkillers

By taking these steps after noticing what is the first sign of kidney problems, you can slow or stop the progression of kidney disease.

Is dialysis painful
Kidney

Is dialysis painful? In-depth guide

June 24, 2025

These eight repeating questions reflect the common anxiety many face when told they need dialysis. The question “Is dialysis painful?” echoes in the minds of patients and families alike. Let’s explore it together, because understanding what dialysis feels like and how discomfort is managed can ease fears, improve quality of life, and empower informed decisions.

What Is Dialysis?

Dialysis is a life-saving medical technique that mimics kidney function by removing waste, excess fluid, and toxins. The two main types include hemodialysis, which uses a machine and filter outside the body, and peritoneal dialysis, which uses the lining of the abdomen. Though essential, dialysis is not always pain-free. Healthcare providers emphasise that while dialysis isn’t typically painful, some discomfort can occur, and it’s important to recognise when and why.

When Pain or Discomfort Can Occur

Though dialysis generally isn’t painful, some parts of the process may cause discomfort:

1. Needle Insertion in Hemodialysis
 During hemodialysis, needles are inserted into the access site (AV fistula, graft, or catheter). Most patients compare it to a mild pinch or sting, similar to a blood draw. Experience shows that this discomfort typically lessens over time as the access site matures.

2. Catheter or Fistula Surgery
 Access surgery, whether to insert a catheter or create a fistula, is performed under local anaesthesia. Post-surgery discomfort can last a couple of days, manageable with pain relief such as paracetamol.

3. Muscle Cramps and Hypotension
 A common side effect during treatment includes muscle cramps and sudden drops in blood pressure. Up to 54% of patients report cramps, and hypotension often leads to nausea or headache. Adjustments in fluid removal and warm saline can alleviate these issues.

4. Drain or Fill Pain in Peritoneal Dialysis
 Some peritoneal dialysis patients experience abdominal discomfort during fluid fill or drain cycles, described as burning, pressure, or even sharp pain. This often resolves with technique adjustments, positioning, or switching to slower drain cycles (like tidal peritoneal dialysis). 

5. Access Site Pain During Dialysis
Occasionally, the fistula needle area might feel throbbing or achy during treatment. Generally, this eases quickly, and proper needle placement prevents long-term discomfort. 

6. Chronic Pain
 Chronic pain, from back pain, joint aches, neuropathy, or bone pain, affects over 50% of patients on long-term hemodialysis. It may impair mobility, sleep, and mood if not managed proactively.

Is dialysis painful

What Patients Say

Patients’ voices often shed light on reality:

  • It’s not painful, only a little more than a typical blood draw… after that, the process is usually painless.
  • Overfill pain is the worst pain I’ve ever experienced. …I still had that pain! … it is so bad I just lay there crying.”
  • Drain and fill pain is unbearable…

These firsthand accounts highlight contrasts: while many find dialysis manageable, some do experience significant discomfort during specific steps or initial learning curves.

Effective Strategies to Reduce Discomfort

There are proven ways to prevent or ease dialysis-associated pain:

Needle Fear and Skin Sensitivity

  • Use numbing creams (e.g., EMLA) or ice sticks before each session.
  • Choose experienced technicians for access cannulation.

Preventing Muscle Cramps and Hypotension

  • Monitor and limit weight gain between sessions.
  • Adjust the ultrafiltration settings and use warm saline boluses to stabilise blood pressure. 

Managing Peritoneal Dialysis Discomfort

  • Experiment with fill volumes, switching to manual drains or slower tidal cycles. 
  • Ensure regular bowel movements and optimal catheter placement to reduce pressure. 

Chronic Pain Management

  • Use multimodal pain relief: safe analgesics, physical therapy, relaxation, CBT, biofeedback, and music therapy.
  • Participate in comprehensive pain-coping programs integrated into dialysis care. 

Patient Education and Comfort

  • Educate on what to expect and involve them in decisions about their settings.
  • Offer environment-enhancements: music, movies, blankets, or distraction tools.

So, Is Dialysis Painful?

Generally speaking, dialysis isn’t meant to be painful. Most discomfort is minor and preventable. The biggest pain moments tend to be during access creation or initial procedures, and even these are short-lived and treatable. Most intradialytic discomfort can be managed through proactive care and patient participation. 

Of course, individual experiences vary. For some, especially during peritoneal dialysis or with chronic pain, it can be significantly painful, highlighting the need for personalised care plans.

Why It Matters

Understanding whether dialysis is painful is critical because:

  • It helps reduce patient anxiety before treatment.
  • It encourages active communication with healthcare teams.
  • It promotes adherence to treatment by addressing discomfort head-on.
  • It opens pathways for non-drug support and holistic pain relief.

Final Thoughts & Expert Care

If you or someone you love is beginning dialysis, trust that modern medical protocols aim for comfort and dignity. Through proper needle techniques, pain relief options, fluid balance management, and chronic-pain strategies, dialysis can be a manageable journey, not a painful burden.

Key takeaway: So, “Is dialysis painful?” Rarely in the long term, discomfort is usually short-lived and manageable. But informed care, communication, and expert medical teams (like those at Kolekar Hospital’s dialysis unit) make all the difference in experience and quality of life.

Kidney

Kidney Dialysis: A Life-Saving Treatment for Kidney Failure

March 17, 2025

Kidney dialysis is a critical medical procedure that helps patients whose kidneys can no longer function effectively. When chronic kidney disease (CKD) or acute kidney failure progresses to an advanced stage, the body is unable to filter waste, excess fluids, and toxins. Dialysis steps in as an artificial filtration process, ensuring that patients maintain a proper balance of fluids and electrolytes.

In this article, we will explore the types of dialysis, who needs it, how it works, and what to expect from treatment

What is Kidney Dialysis?

Kidney dialysis is a treatment that performs the function of the kidneys when they fail. It removes waste, excess fluid, and toxins from the blood, helping to maintain a healthy balance of potassium, sodium, and bicarbonate levels.

Dialysis is not a cure for kidney disease, but it significantly improves quality of life and prolongs survival for patients with kidney failure.

Who Needs Dialysis?

Dialysis is required when kidneys lose about 85-90% of their function. Common conditions that lead to kidney failure include:

  • Chronic Kidney Disease (CKD) – Progressive loss of kidney function over time.
  • Diabetes – High blood sugar can damage kidney tissues.
  • High Blood Pressure (Hypertension) – Strains kidney function and leads to damage.
  • Polycystic Kidney Disease – Genetic condition causing cyst growth in kidneys.
  • Severe Acute Kidney Injury – Sudden kidney failure due to infections, trauma, or medication side effects.

Types of Kidney Dialysis

There are two primary types of kidney dialysis:

1. Hemodialysis

This is the most common type of dialysis, where a dialysis machine and artificial kidney (dialyzer) filter waste and excess fluids from the blood.

Procedure:

  • Blood is drawn from the body through a vascular access.
  • The dialyzer cleans the blood by removing toxins and excess fluid.
  • The filtered blood is returned to the body.

Frequency:

  • Typically 3 times a week, with each session lasting 3-5 hours.
  • Can be done in a hospital, dialysis center, or at home (home hemodialysis).

Pros:
✔ Effective in filtering blood.
✔ Can be done at a medical facility with supervision.

Cons:
✘ Requires frequent visits to the dialysis center.
✘ Risk of infection at the access site.

2. Peritoneal Dialysis (PD)

Peritoneal dialysis is an alternative that allows treatment at home. It uses the body’s peritoneal membrane in the abdomen to filter blood.

Procedure:

  • A special dialysis fluid is introduced into the abdomen through a catheter.
  • The fluid absorbs waste and excess fluid.
  • After a few hours, the fluid is drained and replaced with fresh solution.

Types of Peritoneal Dialysis:

  • Continuous Ambulatory Peritoneal Dialysis (CAPD) – Done manually 4-5 times daily.
  • Automated Peritoneal Dialysis (APD) – A machine cycles the fluid overnight while the patient sleeps.

Pros:
✔ Can be done at home or while traveling.
✔ No need for regular hospital visits.

Cons:
✘ Higher risk of peritoneal infections.
✘ Requires patient responsibility and discipline.

Choosing the Right Dialysis Option

The choice between hemodialysis and peritoneal dialysis depends on:

  • Medical condition and overall health
  • Lifestyle preferences (home vs. center-based treatment)
  • Doctor’s recommendation
  • Availability of support from family or caregivers

For patients with severe conditions, a kidney transplant may be considered as a long-term solution instead of lifelong dialysis.

Living with Dialysis: What to Expect

While dialysis sustains life, it does require adjustments to daily routines. Here’s what patients should be mindful of:

1. Diet and Fluid Intake

  • Limit sodium, potassium, and phosphorus intake to reduce strain on the kidneys.
  • Control fluid intake to prevent swelling and high blood pressure.
  • Eat protein-rich foods to maintain muscle strength.

2. Managing Side Effects

Some patients may experience:

  • Fatigue or weakness due to fluid and electrolyte loss.
  • Low blood pressure (hypotension) during or after hemodialysis.
  • Cramps, itching, or nausea, which can be managed with medications and diet changes.

3. Emotional and Mental Health

Dialysis can be physically and emotionally challenging. Joining support groups, practicing stress management, and maintaining an active lifestyle can help improve mental well-being.

Conclusion

Kidney dialysis is a life-saving treatment that helps patients with kidney failure maintain a healthy and active life. Whether through hemodialysis or peritoneal dialysis, the right treatment plan ensures effective waste removal and improves overall well-being.

At Kolekar Hospital, we provide advanced kidney dialysis in Chembur, ensuring expert care, state-of-the-art facilities, and a compassionate approach. Our specialized nephrologists and dialysis team offer personalized treatment plans to help patients lead a healthier life.
