Treatment of kidney and ureteral with Dr. Alaa Abdel-Hadi Al-Saghir

Kidney and ureteral stones are among the most common medical conditions affecting the urinary system. They can cause severe pain in the sides and lower back, difficulty urinating, and blood in the urine in some cases. These stones develop when minerals and salts in the urine accumulate and form crystals, which may gradually grow into stones of different sizes inside the kidneys or ureters.

Treatment options for kidney and ureteral stones vary depending on the stone's size, location, composition, and its effect on urine flow and kidney function. Therefore, accurate diagnosis is an essential step in selecting the appropriate treatment and preventing complications such as ureteral obstruction, urinary tract infections, and impaired kidney function.

Dr. Alaa Abdel Hady El-Saghir, Consultant of Urology, Kidney Surgery, Andrology, and Male Infertility in Alexandria, provides specialized diagnostic and treatment services for kidney and urinary tract conditions, including the assessment of kidney and ureteral stones and determining the most appropriate treatment approach according to each patient's test results and medical condition.

What Are Kidney and Ureteral Stones?

Kidney stones are hard deposits formed from minerals and salts in the urine inside the kidneys. They can vary in size, ranging from tiny crystals that cause no noticeable symptoms to large stones that may obstruct the urinary tract.

Ureteral stones are stones that move from the kidneys into the ureters, the tubes responsible for carrying urine from the kidneys to the bladder.

Ureteral stones may cause severe pain due to obstruction of urine flow and increased pressure within the urinary system. Some cases require medical intervention to remove the stone and restore normal urine flow.

Causes of Kidney and Ureteral Stones

Several factors can increase the likelihood of developing kidney and ureteral stones, including:

1. Insufficient Water Intake: Inadequate fluid consumption increases the concentration of minerals and salts in the urine, encouraging crystal and stone formation.
2. High Urinary Mineral Levels: Elevated levels of calcium, oxalate, or uric acid in the urine may increase the risk of stone formation.
3. Excessive Salt Consumption: High sodium intake can increase urinary calcium excretion, raising the risk of certain types of kidney stones.
4. Genetic Factors: A family history of kidney stones may increase an individual's risk.
5. Recurrent Urinary Tract Infections: Certain types of bacterial infections can contribute to the formation of specific kidney stones.
6. Metabolic Disorders: Some metabolic and hormonal conditions affect the balance of minerals and salts in the body.
7. Obesity and Excess Weight: Certain metabolic abnormalities associated with obesity may increase the risk of kidney stone formation.
8. Excessive Animal Protein Consumption: High animal protein intake may increase the risk of certain types of stones in susceptible individuals.

Symptoms of Kidney and Ureteral Stones

Symptoms vary depending on the size and location of the stone and whether it causes urinary obstruction.

Common symptoms include:

• Severe pain in one side of the abdomen or lower back.
• Pain extending to the lower abdomen or groin.
• Recurrent episodes of intense pain.
• Burning sensation during urination.
• Frequent urination or a persistent urge to urinate.
• Blood in the urine, which may be visible or detectable only through laboratory testing.
• Nausea and vomiting accompanying episodes of pain.
• Changes in urine color or odor in some cases.

When Are Kidney Stones a Medical Emergency?

Immediate emergency medical attention is necessary if severe pain is accompanied by fever or chills, inability to urinate, or persistent vomiting, particularly when urinary obstruction is suspected. An obstructed urinary system accompanied by infection can be a serious medical emergency requiring urgent intervention.

Types of Kidney and Ureteral Stones

Kidney stones differ according to their chemical composition. The most common types include:

1. Calcium Oxalate Stones

These are among the most common types of kidney stones. They form when calcium combines with oxalate in the urine.

2. Uric Acid Stones

These stones develop when uric acid levels in the urine become elevated or when urine becomes excessively acidic. They may be associated with certain metabolic disorders and gout.

3. Struvite Stones

These stones may form as a result of recurrent urinary tract infections caused by bacteria that produce the enzyme urease. They can grow rapidly and sometimes reach considerable sizes.

4. Cystine Stones

These are less common stones caused by an inherited disorder that affects the kidneys' ability to reabsorb the amino acid cystine.

Identifying the type of stone helps the doctor select the appropriate treatment and develop an effective prevention plan.

How Are Kidney and Ureteral Stones Diagnosed?

Diagnosing kidney and ureteral stones involves a medical examination, laboratory tests, and imaging investigations. These tests help determine the stone's location, size, degree of obstruction, and potential effect on kidney function.

1. Urinalysis

A urine test helps detect blood, crystals, and signs of infection. A urine culture may also be requested if a bacterial infection is suspected.

2. Kidney Function Tests

Blood tests measuring creatinine and estimated glomerular filtration rate (eGFR) help assess kidney function, particularly in cases involving urinary obstruction or recurrent stones.

3. Kidney and Urinary Tract Ultrasound

Ultrasound imaging helps identify many kidney stones and detect signs of urine accumulation inside the kidneys due to urinary obstruction.

4. Non-Contrast CT Scan

A non-contrast computed tomography (CT) scan is one of the most important investigations used to diagnose urinary stones. It helps determine their size, number, location, and the degree to which they affect urine flow.

5. Stone Analysis

When a stone passes naturally or is surgically removed, the doctor may request a chemical analysis to identify its composition and determine the most appropriate preventive measures.

Treatment Options for Kidney and Ureteral Stones

There is no single treatment suitable for every case of kidney or ureteral stones. Treatment selection depends on the stone's size, location, composition, the presence of obstruction or infection, kidney function, and the patient's overall health.

The main treatment options include:

First: Medical Treatment for Kidney and Ureteral Stones

Some small stones can be managed conservatively, particularly when they do not cause significant obstruction or serious complications.

Treatment may include:

• Drinking an appropriate amount of fluids when medically suitable.
• Using appropriate pain-relieving medications.
• Medications that relax the ureter and help facilitate the passage of certain stones, particularly some stones located in the lower ureter.
• Monitoring the stone's size and location through appropriate imaging investigations.

The likelihood of spontaneous stone passage depends on its size and location. Medical treatment alone should not be relied upon in cases requiring intervention.

Second: Extracorporeal Shock Wave Lithotripsy (ESWL)

Extracorporeal shock wave lithotripsy is a procedure that uses focused energy waves to break kidney stones into smaller fragments that can pass naturally through the urine.

It is used in selected cases depending on the stone's size, location, and composition. Some patients may require more than one treatment session.

Third: Ureteroscopy for Stone Treatment

Ureteroscopy is a modern technique used to treat ureteral stones. A thin endoscope is inserted through the urethra and bladder to reach the stone.

The doctor may use laser energy to break the stone into smaller fragments, which can then be removed or allowed to pass naturally, depending on the case.

One of the main advantages of this procedure is that it usually does not require an external surgical incision and allows direct access to the stone.

Fourth: Flexible Ureteroscopy for Kidney Stones

Flexible ureteroscopy allows the doctor to reach different areas of the kidneys through the urinary tract. Laser energy can then be used to fragment stones located inside the kidneys.

It is an important treatment option for selected kidney stones, particularly those that are difficult to reach using conventional endoscopic techniques.

The suitability of this procedure depends on the stone's size, location, number, and the patient's medical condition.

Fifth: Percutaneous Nephrolithotomy (PCNL)

Percutaneous nephrolithotomy is used to treat certain large or complex kidney stones, particularly stones occupying substantial portions of the kidney.

During the procedure, a small access tract is created through the skin to reach the kidney. An endoscope is then inserted to fragment and remove the stones.

This procedure may be suitable for large or staghorn stones that are not appropriate for other treatment methods.

Can Kidney and Ureteral Stones Be Treated with Laser Technology?

Yes. Laser technology is used to treat many types of kidney and ureteral stones through specialized endoscopic procedures.

The technique involves inserting a thin endoscope to reach the stone and using laser energy to break it into smaller fragments.

The main advantages of laser stone treatment include:

• Accessing kidney and ureteral stones in selected cases.
• Precise stone fragmentation.
• Avoiding external surgical incisions in many endoscopic procedures.
• Treating multiple stones when appropriate.
• Reducing the need for open surgery in many cases.

However, laser treatment is not necessarily the best option for every patient. The appropriate technique depends on the stone's size, location, composition, and the presence of complications.

When Do Kidney Stones Require Surgery?

A surgical or endoscopic intervention may be necessary in the following situations:

• Large stones that are unlikely to pass naturally.
• Persistent pain despite appropriate medical treatment.
• Ureteral obstruction or impaired kidney function.
• Recurrent urinary tract infections associated with stones.
• Large or complex kidney stones.
• Failure of other treatment methods to remove the stone.

In certain cases of urinary obstruction accompanied by infection, the priority is to drain the urinary system and treat the infection urgently. Definitive stone removal is then performed after the patient's condition has stabilized.

Can Kidney and Ureteral Stones Cause Kidney Failure?

Kidney and ureteral stones may affect kidney function if they cause prolonged or recurrent urinary obstruction, particularly when both kidneys are obstructed or when the patient has only one functioning kidney.

Repeated infections associated with stones may also damage kidney tissue in certain cases.

Therefore, stone-related symptoms should never be ignored. Early diagnosis and appropriate treatment are essential to preventing complications.

Important Tips to Prevent Kidney and Ureteral Stones

Healthy lifestyle habits can help reduce the risk of stone formation, particularly in people who have previously experienced kidney stones.

1. Drink Water Regularly: Adequate fluid intake increases urine volume and reduces the concentration of minerals that contribute to stone formation.
2. Reduce Salt Intake: Excessive sodium consumption may increase the risk of certain types of kidney stones.
3. Moderate Animal Protein Consumption: This is particularly important for individuals at risk of uric acid stones.
4. Maintain Adequate Dietary Calcium: Calcium from normal food sources should not be unnecessarily restricted, as low dietary calcium may increase oxalate absorption.
5. Eat Vegetables and Fruits: Include a variety of vegetables and fruits in a balanced diet.
6. Maintain a Healthy Weight: This helps reduce some metabolic risk factors associated with kidney stone formation.
7. Attend Regular Medical Checkups: Particularly important for patients with recurrent stones or a family history.
8. Analyze Recurrent Stones: Identifying the stone's composition helps develop an individualized prevention plan.

Some patients may also require specialized 24-hour urine testing to identify the underlying causes of stone formation and establish appropriate preventive measures.
