Understanding Kidney Stones

Kidney stones are hard deposits made of minerals and salts that form inside the kidneys. They can vary in size, from tiny grains like sand to large stones that fill the kidney.
Common causes include:

  • Dehydration

  • High salt intake

  • Excess consumption of oxalate-rich foods

  • Family history of kidney stones

  • Certain medical conditions such as hyperparathyroidism or urinary tract infections

When Do Kidney Stones Need Surgery?

Not all kidney stones require surgery. In fact, small stones (less than 5 mm) often pass naturally. Surgery is usually recommended when:

1. The Stone Is Too Large

  • Stones larger than 6–7 mm in diameter rarely pass on their own.

  • Large stones can block the urinary tract and cause kidney damage.

  • Surgical procedures like Percutaneous Nephrolithotomy (PCNL) or Ureteroscopy (URS) are often advised in such cases.

2. Persistent and Severe Pain

  • Intense flank or back pain that doesn’t improve with painkillers may indicate the need for surgical removal.

  • If the pain continues for days despite medication, it suggests the stone is not moving or is causing significant obstruction.

3. Recurrent Urinary Tract Infections (UTIs)

  • Kidney stones can harbor bacteria, leading to repeated infections.

  • If antibiotics are not controlling the infection due to the presence of a stone, surgery is necessary to eliminate the root cause.

4. Kidney Function Decline

  • A blocked urinary tract can increase pressure in the kidney, leading to damage.

  • If diagnostic tests show reduced kidney function due to obstruction, surgery becomes urgent to restore normal flow.

5. Uncontrolled Bleeding

  • Some stones cause injury to the urinary tract lining, resulting in blood in urine (hematuria).

  • If bleeding persists and is linked to a kidney stone, surgical intervention may be needed.

6. Stones in Only One Functioning Kidney

  • People with a single functional kidney cannot risk prolonged blockage.

  • Immediate removal of the stone is crucial to prevent kidney failure.

7. Failure of Other Treatments

  • If medical therapy, hydration, and lifestyle changes fail to help after several weeks, surgery is often the next step.

Types of Kidney Stone Surgeries

Modern urology offers several minimally invasive options, which are available at leading centers like Sarvesh Health City.

1. Extracorporeal Shock Wave Lithotripsy (ESWL)

  • Uses sound waves to break stones into small pieces.

  • Suitable for stones less than 2 cm in the kidney or upper ureter.

  • Outpatient procedure with minimal recovery time.

2. Ureteroscopy (URS)

  • A thin scope is passed through the urethra and bladder into the ureter to remove or break the stone.

  • Ideal for mid to lower ureter stones.

  • Often combined with laser technology for precision.

3. Percutaneous Nephrolithotomy (PCNL)

  • Recommended for large stones or multiple stones.

  • A small incision is made in the back to access and remove stones directly.

  • Performed under general anesthesia.

4. Laparoscopic or Open Surgery

  • Rarely needed, only in cases where other procedures are not possible.

  • Used for extremely large or complex stones.

Medical Guidelines for Surgery

The decision for kidney stone surgery is based on several standard medical guidelines:

  1. Stone Size and Location

    • 6 mm: Surgery is often considered.

    • Stones in lower ureter with severe symptoms may be treated earlier.

  2. Pain Duration

    • Severe pain lasting more than 48–72 hours without improvement.

  3. Obstruction Severity

    • Complete or partial blockage seen on imaging tests like ultrasound or CT scan.

  4. Presence of Infection

    • Fever with urinary blockage requires urgent drainage or stone removal.

  5. Kidney Function

    • Reduced glomerular filtration rate (GFR) or hydronephrosis is a surgical indication.

  6. Patient Health

    • Overall health, comorbidities, and surgical risk factors are assessed before proceeding.

Post-Surgery Recovery

Recovery depends on the type of procedure performed:

  • ESWL: Resume daily activities in 1–2 days.

  • URS: Slight discomfort for 2–3 days, normal activities within a week.

  • PCNL: Hospital stay of 1–2 days, complete recovery in 2–3 weeks.

Preventing Future Kidney Stones

Even after surgery, lifestyle changes are vital to avoid recurrence:

  • Drink 2–3 liters of water daily.

  • Reduce salt and processed food intake.

  • Limit foods high in oxalates like spinach, nuts, and chocolate.

  • Include citrus fruits to increase urinary citrate, which prevents stone formation.

  • Follow your doctor’s dietary recommendations based on stone type.
