Hydronephrosis means that urine has accumulated in the kidney because its normal drainage is impaired. This can cause the kidney's collecting system to become enlarged or dilated.

It is not a separate disease with one universal treatment. Instead, hydronephrosis is usually a sign of an underlying problem affecting urine drainage.

Possible causes include:

• Kidney or ureteral stones

• Narrowing of the ureter

• Enlarged prostate

• Urinary tract abnormalities

• Tumors or masses

• Blood clots

• Bladder emptying problems

• Congenital abnormalities

• Pregnancy-related urinary changes in selected cases

Because the cause determines treatment, there is no proven natural remedy that can remove every cause of hydronephrosis.

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation of kidney swelling, reduced kidney function and conditions associated with urinary obstruction.

Can Hydronephrosis Be Treated Naturally?

The answer depends on why the kidney is swollen and whether urine flow is obstructed.

Mild hydronephrosis caused by a temporary or reversible condition may improve when the underlying problem resolves.

However, if a stone, narrowing or another physical blockage is preventing urine from leaving the kidney, diet, herbs or extra water generally cannot remove that obstruction.

Therefore, the safest approach is to identify the cause first.

The term “natural treatment” should not be interpreted as replacing medical treatment when obstruction is significant.

Why Does Hydronephrosis Happen?

Urine normally travels from the kidneys through the ureters into the bladder.

If something interferes with this pathway, urine may accumulate upstream.

Kidney Stones

A stone can become lodged in the ureter and interfere with urine drainage.

Depending on the stone's size and location, observation, medication, ureteroscopy, shock wave treatment or another procedure may be considered.

Ureteral Narrowing

A scar or narrowing of the ureter can restrict urine flow.

Persistent narrowing may require specialist treatment rather than home remedies.

Enlarged Prostate

In men, prostate enlargement can interfere with bladder emptying and may contribute to urinary tract dilation.

Urinary Tract Abnormalities

Some people have structural abnormalities that affect urine drainage from childhood or develop them later in life.

Masses or Tumors

A mass in or around the urinary tract can sometimes compress or obstruct the normal drainage pathway.

This requires appropriate imaging and specialist evaluation.

Can Mild Hydronephrosis Go Away on Its Own?

Sometimes.

If the cause is temporary and urine drainage returns to normal, mild hydronephrosis may improve.

For example, some cases associated with a passing stone or temporary urinary changes can resolve after the obstruction is relieved.

However, the disappearance of pain does not necessarily prove that hydronephrosis has resolved.

Follow-up imaging may be needed to determine whether the kidney has returned to normal.

Is Drinking More Water a Natural Treatment for Hydronephrosis?

No, not in every case.

Drinking an appropriate amount of fluid is important for general health and may be part of kidney-stone prevention for selected people.

But if urine cannot pass because of a physical obstruction, drinking large amounts of water does not remove the blockage.

In some circumstances, excessive fluid intake may increase discomfort or worsen fluid-related problems.

People with kidney disease, heart disease, reduced urine output or prescribed fluid restrictions should follow individualized medical advice.

Can Lemon Water Treat Hydronephrosis?

Lemon water is sometimes promoted online as a natural remedy for kidney problems.

While citrus beverages can contribute dietary citrate, which may be relevant to prevention of some types of kidney stones, lemon water does not directly open a blocked ureter or reverse established hydronephrosis.

It should therefore not be considered a treatment for urinary obstruction.

If a kidney stone is responsible for hydronephrosis, the stone's size, location and effect on urine flow need to be evaluated.

Can Herbal Remedies Cure Hydronephrosis?

There is no established herbal remedy that reliably removes urinary obstruction and treats every form of hydronephrosis.

Herbal products may also contain ingredients that interact with prescribed medicines or may be unsuitable for people with impaired kidney function.

Patients with kidney disease should be particularly cautious about unverified “kidney cleansing” or “kidney detox” products.

Do not delay appropriate medical evaluation in favor of herbal treatment.

Natural and Supportive Measures That May Help

Although natural measures cannot replace treatment for an obstruction, some lifestyle measures can support general urinary and kidney health.

Maintain Appropriate Fluid Intake

Fluid requirements should be individualized.

For some people with recurrent kidney stones, adequate hydration is an important preventive measure.

However, fluid intake should not be forced when urine flow is obstructed or when a doctor has prescribed a fluid restriction.

Avoid Excessive Salt

A high-sodium diet can contribute to several kidney and cardiovascular problems and may increase urinary calcium in some people who form calcium stones.

Reducing excessive dietary salt can therefore be useful as part of a broader kidney-health plan.

Follow an Appropriate Diet

Dietary recommendations depend on the underlying condition.

Someone with recurrent calcium stones may receive different advice from a patient with chronic kidney disease, diabetes or another kidney disorder.

Avoid extreme diets based on internet recommendations.

Avoid Unnecessary Painkillers

Some pain medicines, particularly NSAIDs, can affect kidney function in susceptible people.

If hydronephrosis is accompanied by kidney-function impairment or dehydration, medication choices should be discussed with a healthcare professional.

Monitor Symptoms

If hydronephrosis has already been diagnosed, keep track of:

• Pain

• Fever

• Urine output

• Burning while urinating

• Blood in urine

• Vomiting

• Changes in general health

Worsening symptoms may require prompt reassessment.

How Is the Cause of Hydronephrosis Diagnosed?

Finding the cause is more important than simply treating the appearance of a swollen kidney.

Ultrasound

Ultrasound can identify dilation of the kidney's collecting system and may provide information about the urinary tract.

CT Scan

When a stone or other obstruction is suspected, CT imaging may provide more detailed information about:

• Stone size

• Stone location

• Urinary obstruction

• Kidney anatomy

• Other structural abnormalities

The type of CT required depends on the clinical situation.

Blood Tests

Doctors may assess:

• Serum creatinine

• eGFR

• Electrolytes

• Blood count

• Other tests when indicated

These help determine whether the obstruction is affecting kidney function.

Urine Tests

Urinalysis may detect:

• Blood

• Infection

• Protein

• Other abnormalities

A urine culture may be recommended when infection is suspected.

What Symptoms Can Hydronephrosis Cause?

Hydronephrosis may cause no symptoms, particularly when it develops gradually.

When symptoms occur, they can include:

• Flank or side pain

• Back discomfort

• Abdominal pain

• Nausea

• Vomiting

• Changes in urination

• Blood in urine

• Burning during urination

• Recurrent urinary infections

Symptoms depend largely on the underlying cause and whether urine drainage is significantly impaired.

Can Hydronephrosis Damage the Kidney?

Persistent or severe obstruction can impair kidney function.

The degree of risk depends on factors such as:

• Severity of obstruction

• Duration of obstruction

• Whether one or both kidneys are affected

• Presence of infection

• Baseline kidney function

• Underlying cause

Early evaluation can help determine whether intervention is needed to protect kidney function.

What If Both Kidneys Have Hydronephrosis?

Hydronephrosis affecting both kidneys deserves careful evaluation because obstruction involving both sides can significantly reduce overall urine drainage and kidney function.

Possible causes may include:

• Bladder outlet obstruction

• Enlarged prostate

• Urethral or bladder abnormalities

• Certain pelvic masses

• Bilateral urinary tract obstruction

If urine output falls significantly or kidney-function tests worsen, urgent medical assessment may be required.

Hydronephrosis With Kidney Stones

When a kidney stone causes hydronephrosis, treatment depends on the stone's characteristics.

Possible approaches include:

Observation

Selected small stones with a reasonable likelihood of spontaneous passage may be monitored.

Medical Treatment

Pain control and, in selected situations, medication to facilitate passage may be considered.

Shock Wave Lithotripsy

Shock waves can fragment certain stones from outside the body.

Ureteroscopy and Laser Treatment

A ureteroscope can be passed through the urinary tract to reach the stone, where laser lithotripsy may fragment it.

Other Procedures

Larger or complex renal stones may require procedures such as percutaneous nephrolithotomy.

The appropriate option depends on the stone's size, location, density, anatomy, infection status and kidney function.

When Does Hydronephrosis Need a Procedure?

A procedure may be considered when there is:

• Significant or persistent obstruction

• Declining kidney function

• Severe or persistent pain

• Recurrent infection

• A stone unlikely to pass

• Complete or near-complete blockage

• Obstruction affecting both kidneys

• Obstruction of a solitary functioning kidney

• Another structural cause requiring correction

The purpose of intervention is to restore or protect urine drainage and prevent kidney damage.

What Is Urgent Hydronephrosis?

Hydronephrosis becomes particularly concerning when obstruction is accompanied by infection.

Warning signs can include:

• Fever

• Chills

• Severe flank pain

• Vomiting

• Reduced urine output

• Confusion

• Severe weakness

• Rapid deterioration

An infected obstructed urinary system can become a serious medical emergency.

In such cases, urgent drainage of the urinary system may be necessary, often using a ureteral stent or nephrostomy, followed by definitive treatment of the underlying cause when the infection has been appropriately managed.

Can Hydronephrosis Be Treated Without Surgery?

Sometimes.

Not every patient with hydronephrosis needs surgery.

Management can range from observation and treatment of the underlying medical condition to minimally invasive procedures.

For example, if a small stone is likely to pass and there is no infection or significant kidney impairment, a doctor may recommend observation with appropriate follow-up.

However, a persistent physical blockage generally cannot be reliably treated with diet or home remedies alone.

How Long Does Hydronephrosis Take to Improve?

There is no fixed recovery period.

The time depends on:

• Cause of obstruction

• Duration of obstruction

• Severity of hydronephrosis

• Kidney function

• Whether the blockage is completely or partially relieved

• Presence of infection

• Individual healing response

Some cases improve relatively quickly after urine flow is restored, while long-standing obstruction may cause damage that takes longer to recover or may not completely reverse.

How Is Hydronephrosis Monitored After Treatment?

Follow-up may include:

• Repeat ultrasound

• CT imaging when appropriate

• Creatinine and eGFR

• Urine testing

• Assessment of urine output

• Review of symptoms

The timing of follow-up depends on the cause and treatment.

A reduction in symptoms is helpful but may not be enough to confirm that the obstruction has completely resolved.

How Can Future Kidney Stones and Obstruction Be Prevented?

Prevention depends on the cause.

For people prone to kidney stones, preventive strategies may include:

• Appropriate fluid intake

• Reducing excessive dietary sodium

• Maintaining an appropriate dietary calcium intake

• Stone analysis when a stone is recovered

• Metabolic evaluation for recurrent stone formers

• Taking prescribed preventive medicines

• Treating recurrent urinary infections

• Following recommended imaging and specialist follow-up

Not every patient requires the same diet or preventive medication.

Hydronephrosis Evaluation at Prabhakar Bhurke Clinic

At Prabhakar Bhurke Clinic, Dr. Sandip Prabhakar Bhurke, super specialist nephrologist and transplant physician, provides individualized evaluation for patients with hydronephrosis and related kidney-function concerns.

Depending on the clinical situation, assessment may include:

• Review of ultrasound or CT findings

• Kidney-function evaluation

• Creatinine and eGFR testing

• Urine examination

• Assessment of urinary obstruction

• Evaluation for kidney stones

• Infection assessment

• Review of medications and medical history

• Monitoring after obstruction treatment

• Coordination with appropriate urological specialists when a procedure is required

The goal is to identify the cause of hydronephrosis, assess its effect on kidney function and determine whether observation, medical management or an intervention is appropriate.

Frequently Asked Questions

What is the best natural treatment for hydronephrosis?

There is no universal natural treatment for hydronephrosis. Mild cases caused by a temporary problem may improve after the underlying issue resolves, but a physical obstruction may require medical or procedural treatment.

Can drinking water cure hydronephrosis?

No. Adequate hydration may support general kidney health and help prevent some kidney stones, but drinking excessive water cannot reliably remove a blocked ureter.

Can hydronephrosis go away without surgery?

Yes, some cases can improve without surgery if the underlying obstruction is temporary or resolves naturally. However, persistent or significant obstruction may require intervention.

Can lemon juice cure hydronephrosis?

No. Lemon juice does not directly remove urinary obstruction or reverse hydronephrosis. Citrus may have a role in some kidney-stone prevention plans, but it is not a treatment for a blocked urinary tract.

Is hydronephrosis dangerous?

It can be, particularly when obstruction is severe, prolonged, associated with infection or affecting kidney function. The seriousness depends on the cause and degree of obstruction.

Does hydronephrosis always cause pain?

No. Some people have hydronephrosis without obvious symptoms, particularly when it develops gradually.

Can a kidney stone cause hydronephrosis?

Yes. A stone lodged in the ureter can interfere with urine drainage and cause dilation of the kidney's collecting system.

When should hydronephrosis be treated urgently?

Fever or chills with urinary obstruction, very low urine output, severe pain, persistent vomiting, confusion or rapidly worsening symptoms require urgent medical assessment.

Conclusion

Hydronephrosis natural treatment depends largely on what is causing the kidney to become swollen.

There is no single food, drink, herb or home remedy that can safely remove every cause of hydronephrosis. If the problem is mild and temporary, the condition may sometimes improve after the underlying cause resolves. However, a persistent obstruction caused by a stone, narrowing, prostate problem or another structural condition may require medical or minimally invasive treatment.

Appropriate evaluation can determine whether observation is reasonable or whether the urinary tract needs to be relieved of obstruction. Kidney-function testing and follow-up imaging are important when hydronephrosis has been diagnosed.

If you have been told that you have hydronephrosis, do not rely solely on natural remedies or excessive water intake before determining the cause.
