Urinary Calculi

Urinary Calculi

Definition Urinary calculi, also known as kidney stones, are small, hard mineral deposits that form inside the urinary tract. They can cause severe pain and other complications if they block the flow of urine.

Causes / Etiology The causes of urinary calculi can be broadly divided into two categories - intrinsic and extrinsic factors.

Intrinsic factors are due to the abnormalities in the urinary tract itself. These include:

• Imbalanced pH levels in the urine
• Presence of certain chemicals or minerals in the urine
• Abnormalities in the shape or function of the urinary tract
• Presence of certain medical conditions like kidney disease or urinary tract infections

Extrinsic factors are due to external factors that can influence the formation of urinary calculi. These include:

• Genetics: Some people may be more prone to developing urinary calculi due to their genetic makeup.
• Diet: A diet that is high in animal protein, sodium, and sugar can increase the risk of urinary calculi.
• Lifestyle factors: Factors like dehydration, lack of physical activity, and smoking can also increase the risk.

Types or Classification Urinary calculi can be classified into several types based on their composition and location. These include:

• Calcium stones: These are the most common type of urinary calculi and are usually composed of calcium oxalate or calcium phosphate.
• Uric acid stones: These stones are usually composed of uric acid and can form in people with gout or kidney disease.
• Cystine stones: These stones are usually composed of cystine and can form in people with a genetic disorder called cystinuria.
• Struvite stones: These stones are usually composed of magnesium ammonium phosphate and can form in people with urinary tract infections.
• Xanthine stones: These stones are usually composed of xanthine and can form in people with certain genetic disorders.

Pathology The formation of urinary calculi is a complex process that involves several steps. Here's a simplified explanation:

Step 1 → Step 2 → Step 3 → Step 4

• Step 1: The urine in the kidneys becomes concentrated due to a variety of factors like dehydration or an imbalance in the pH levels.
• Step 2: Minerals and salts in the urine start to precipitate out and form crystals.
• Step 3: These crystals continue to grow and aggregate, eventually forming a stone.
• Step 4: The stone can then migrate down the urinary tract, causing blockages and other complications.

Clinical Features The clinical features of urinary calculi can vary depending on the location and size of the stone. General clinical features include:

• Severe pain in the flank or side
• Nausea and vomiting
• Frequent or painful urination
• Blood in the urine
• Fever and chills
• Abdominal tenderness

Specific clinical features depend on the location of the stone. For example, a stone in the kidney can cause pain in the flank or side, while a stone in the ureter can cause pain in the lower abdomen or groin.

Complications Urinary calculi can cause several complications if left untreated. Acute complications include:

• Obstruction of the urinary tract
• Infection of the urinary tract
• Kidney damage
• Blood clots

Chronic complications include:

• Kidney damage or disease
• Urinary tract infections
• Bladder problems like incontinence or urine retention
• Increased risk of other urinary tract problems like kidney stones or urinary incontinence.

Diagnosis / Investigations The diagnosis of urinary calculi is usually made based on a combination of symptoms, physical examination, and medical imaging tests. Routine investigations include:

• Urine analysis to check for blood, infection, or abnormal chemical levels
• Imaging tests like ultrasound, X-ray, or CT scan to visualize the stone
• Blood tests to check for kidney function or other underlying conditions

Special investigations include:

• Intravenous pyelography (IVP) to visualize the urinary tract
• Retrograde pyelography to visualize the ureter and bladder
• Ureteroscopy to visualize the inside of the ureter

Management The management of urinary calculi depends on the size, location, and composition of the stone. General management includes:

• Pain relief medication to manage pain and discomfort
• Fluid therapy to stay hydrated and help flush out the stone
• Dietary changes to reduce the risk of future stones
• Medical treatment to manage underlying conditions like kidney disease or urinary tract infections

Modern treatment includes:

• Extracorporeal shock wave lithotripsy (ESWL) to break up the stone
• Ureteroscopy to remove the stone
• Percutaneous nephrolithotomy (PCNL) to remove the stone through the skin
• Open surgery to remove the stone

Dietary advice includes:

• Increasing fluid intake to stay hydrated
• Reducing animal protein and sodium intake
• Increasing potassium and citrate intake
• Avoiding foods that are high in oxalate or other minerals that can contribute to stone formation.
