Ureteral hernia causes symptoms treatment and when it becomes dangerous

Ureteral hernia is a rare medical condition that many people may not have heard of, yet it can cause significant problems in the urinary system if it is not detected early. This disorder occurs when the ureter—the tube responsible for carrying urine from the kidneys to the bladder—moves out of its normal anatomical position or slips into a hernia in the abdominal wall. This displacement can lead to impaired urine flow or increased pressure on the kidneys over time.Although symptoms may be mild or unclear in the early stages, ignoring them can result in serious complications such as urinary tract obstruction or a gradual decline in kidney function. Therefore, early diagnosis and a proper understanding of the condition are essential for effective treatment and for preventing potential risks.In this article from Delili Medical, we will take you on a simple and comprehensive journey to understand ureteral hernia from all aspects: its causes, symptoms, diagnostic methods, available treatments, and when it becomes a medical emergency requiring urgent intervention.

❓ 1. What is a ureteral hernia?

It is a rare condition in which part of the ureter moves out of its normal position within the abdominal wall or enters a hernia sac. This can affect the normal flow of urine.

❓ 2. Is a ureteral hernia dangerous?

Not always, but it can become serious if it leads to:

Urinary tract obstruction
Damage to kidney function
Recurrent urinary tract infections

❓ 3. Can a ureteral hernia be treated without surgery?

In most cases ❌ no.

Medications may help relieve symptoms, but the definitive treatment is usually surgical repair to fix the problem permanently.

❓ 4. Does a ureteral hernia cause pain?

Yes ✔️

Pain may appear in:

Lower abdomen or groin area
Flank or lower back in some cases

❓ 5. Does a ureteral hernia affect urination?

Yes, it may cause:

Difficulty urinating
Slow urine flow
Frequent urinary tract infections
Sometimes blood in the urine

❓ 6. Can a ureteral hernia heal on its own?

❌ No, in most cases it does not heal on its own and may worsen over time if left untreated.

❓ 7. What is the difference between a ureteral hernia and a ureteral stone?

Ureteral stones: Hard deposits of salts and minerals formed inside the urinary tract.
Ureteral hernia: A condition where the ureter moves out of its normal position or slips into a hernia sac in the abdominal wall.

❓ 8. When should you see a doctor urgently?

Seek medical attention immediately if you experience:

Severe and persistent pain
Difficulty or inability to urinate
Fever or repeated infections
Swelling in the abdomen or groin

Types of ureteral hernia

A ureteral hernia is rare, and its types depend on where the ureter enters the hernia sac and the type of abdominal wall defect.

1. Inguinal hernia

Most commonly associated with ureteral hernia
Occurs in the groin area
Part of the ureter may slip into the hernia sac without early detection
✔️ This is the most common type in this condition

2. Femoral hernia

Appears below the inguinal region
Less common
May compress or displace the ureter in rare cases

3. Incisional hernia

Occurs at the site of a previous abdominal surgery
Caused by weakness in the abdominal wall after operations
May allow the ureter to enter the weakened area

4. Congenital hernia

Present at birth
Caused by a developmental defect in the abdominal wall or ureter position
Very rare and more commonly seen in children

⚠️ Causes of ureteral hernia

A ureteral hernia usually occurs due to weakness in the abdominal wall or increased internal pressure, and it is often associated with inguinal hernia.

Main causes:

1. Weak abdominal wall

The most common cause
Allows internal organs, including the ureter, to protrude

2. Inguinal hernia

Strongly associated with the condition
The ureter may slip into the hernia sac unnoticed

3. Congenital defects

Birth-related abnormalities in the abdominal wall or ureter pathway
Increase the risk of hernia formation

4. Aging

Muscle and tissue weakness over time
Reduces abdominal wall strength

⚖️ 5. Increased intra-abdominal pressure

Such as:

Heavy lifting
Chronic coughing
Severe constipation
Obesity

These factors increase internal pressure and contribute to hernia formation.

6. Previous abdominal surgeries

Weaken the abdominal wall
Increase the risk of later hernia development

⚖️ 7. Obesity

Increased constant pressure on the abdominal wall
It is an important factor in the development of hernias

Stages of ureteral hernia

Ureteral hernia is a rare condition, and its progression is gradual depending on how much the ureter has displaced and how this affects urine flow and kidney function.

Stage 1: Mild stage

A small part of the ureter enters the hernia sac
Usually no clear symptoms
May only cause mild discomfort
Often difficult to detect at this stage

Stage 2: Early symptoms

Mild pain in the lower abdomen or groin
Feeling of heaviness or pulling in the hernia area
Slight effect on urine flow in some cases

Stage 3: Ureter involvement

Noticeable pressure on the ureter
Slow or difficult urine flow
Early mild kidney swelling (urinary congestion)
Possible recurrent urinary tract infections

Stage 4: Partial obstruction ⚠️

Clear blockage of urine flow
Pain in the flank or back similar to kidney colic
Swelling of the kidney pelvis (hydronephrosis)
Increased risk of urinary infections

Stage 5: Complete obstruction and severe risk

Severe or complete urinary blockage
Strong and persistent pain
Decline in kidney function
Possible permanent kidney damage if untreated

⚠️ Symptoms of ureteral hernia

Ureteral hernia may not cause clear symptoms in early stages, but as it progresses, symptoms begin to appear.

Main symptoms:

1. Lower abdominal or groin pain

Mild to moderate pain
Worsens with standing or physical effort

2. Swelling in the hernia area

Usually in the groin region
Becomes more visible with coughing or lifting heavy objects

3. Symptoms of ureteral obstruction

Pain in the flank or back
Weak urine flow
Feeling of incomplete bladder emptying

4. Recurrent infections

Due to urine retention
Burning sensation during urination or frequent urination

5. Blood in urine

Caused by irritation or pressure on the ureter

6. Increased pain with movement

Such as coughing, standing for long periods, or lifting heavy objects

7. Advanced cases ⚠️

Severe ureteral blockage
Strong pain similar to kidney colic
Increased size of swelling

Diagnosis of ureteral hernia

Diagnosing ureteral hernia requires high accuracy because it is rare and may resemble kidney stones or urinary tract infections. Therefore, doctors use multiple diagnostic tools.

1. Medical history and physical examination

Asking about pain location and severity
Checking for groin or lower abdominal swelling
Urinary symptoms such as burning or difficulty urinating
Physical exam of the groin area for visible hernia

2. Urine analysis

Helps evaluate:

Blood in urine
Signs of infection such as pus or bacteria
General urinary tract health

3. Blood tests

Kidney function tests (creatinine and urea)
Assessing kidney damage due to obstruction

4. Imaging (most important)

⭐ CT Urography (CT scan with contrast)

Most accurate test
Shows the full ureter path
Identifies hernia location
Detects obstruction or kidney swelling

Ultrasound

Shows kidney or ureter swelling
Helps suspect obstruction
Less accurate for confirming hernia

Plain X-ray

Does not clearly show hernia
Mainly used to rule out kidney stones

5. Additional tests

Contrast studies of the urinary tract
Functional tests to track urine flow

⚠️ Complications of ureteral hernia

Ureteral hernia may seem mild at first, but it can lead to serious complications if untreated.

Main complications:

1. Ureteral obstruction

One of the most serious complications
Blocks normal urine flow
Increases pressure on the kidneys

2. Hydronephrosis (kidney swelling)

Caused by urine buildup behind the blockage
Leads to kidney enlargement
Causes flank or back pain

3. Kidney function decline

Occurs with long-term obstruction
Reduces the kidney’s ability to filter blood
May lead to permanent damage in advanced cases

4. Urinary tract infections

Caused by urine stagnation
Symptoms: fever, burning urination, pain

5. Chronic or recurrent pain

In lower abdomen or groin
Worsens with movement or physical activity

6. Blood in urine

Due to irritation or pressure on the ureter

7. Progression over time

Gradual increase in hernia size
Increased pressure on ureter and nearby organs

Prevention of ureteral hernia

Ureteral hernia is rare and usually related to abdominal wall weakness or increased abdominal pressure, so prevention focuses on reducing risk factors.

Main preventive measures:

1. Strengthen abdominal muscles

Regular light exercise
Maintaining core muscle strength
Helps reduce risk of hernia in general

2. Maintain a healthy weight

Obesity increases abdominal pressure
Weight loss reduces hernia risk

3. Avoid improper heavy lifting

Do not lift heavy objects suddenly
Use correct lifting techniques (legs instead of back)

4. Treat chronic constipation

Straining increases abdominal pressure
Eat fiber-rich foods and drink plenty of water

5. Treatment of chronic cough

Persistent coughing increases pressure inside the abdomen
The underlying cause should be treated, such as smoking or chest diseases

6. Follow-up after surgery

Especially abdominal surgeries
Weakness in the abdominal wall after surgery increases the risk of hernia

⚠️ 7. Early symptom awareness

Pain or swelling in the abdomen or groin
See a doctor immediately if any abnormal sign appears

⚠️ Complications of ureteral hernia

Ureteral hernia can lead to serious complications if not treated in time, especially if it affects urine flow and kidney function.

Main complications:

1. Ureteral obstruction

One of the most serious complications
Prevents urine from flowing from the kidney to the bladder
Causes pressure on the kidneys

2. Hydronephrosis (kidney swelling)

Caused by urine buildup behind the blockage
Leads to enlargement of the kidney pelvis
Causes pain in the flank or back

3. Decline in kidney function

With prolonged obstruction
The kidney loses its ability to filter blood effectively
May lead to permanent damage in severe cases

4. Urinary tract infections

Due to urine retention
Symptoms include fever, pain, and burning during urination
Infection may reach the kidneys

5. Chronic or recurrent pain

In the lower abdomen, groin, or flank
Worsens with movement or physical effort

6. Blood in urine

Due to pressure or irritation of the ureter

7. Worsening over time

Gradual increase in hernia size
Increased pressure on the ureter
Progression of obstruction and complications

Medical treatment of ureteral hernia

Ureteral hernia cannot be permanently treated with medications because the main issue is the displacement or compression of the ureter, not just infection or pain.

However, medications are used as supportive treatment to relieve symptoms and prevent complications.

Goals of drug treatment:

Pain relief
Treat infections if present
Indirectly improve urine flow
Protect kidney function

1. Painkillers

Non-steroidal anti-inflammatory drugs (NSAIDs)
Or stronger pain relievers depending on severity
Help reduce pain and muscle spasms

2. Antibiotics (if infection is present)

Used only when there is a urinary infection such as:

Fever
Burning during urination
Pus in urine

Goal: prevent infection from reaching the kidneys

3. Medications to improve urine flow

Relax urinary tract muscles
Reduce resistance to urine flow
⚠️ They do not treat the hernia itself

4. Symptom-relief medications

Such as:

Anti-spasmodic drugs
Bladder soothing medications
Medicines to reduce urinary discomfort

Surgical treatment of ureteral hernia

Ureteral hernia cannot be cured with medication alone. If it affects urine flow or kidney function, surgery is the main treatment to restore the ureter to its normal position and repair the hernia.
