Ketamine and bladder problems: symptoms you shouldn’t ignore

Ketamine use can cause significant damage to the bladder and other parts of the urinary system. A constant urge to urinate, pain or a burning sensation when doing so, blood in the urine and difficulty controlling the bladder should not be regarded as minor or temporary effects.

These symptoms may be linked to what is known as ketamine-induced cystitis, also known as ketamine bladder syndrome or ketamine uropathy.

The risk is particularly heightened when use is frequent, prolonged or in large quantities. However, urinary problems may arise before the person realises they have developed a dependence. The available evidence links the frequency and quantity consumed to a higher likelihood of developing urinary symptoms.

Recognising the early signs and seeking specialist medical care can help prevent the damage from progressing further.

What is the link between ketamine and the bladder?

Ketamine is a substance used in medicine as an anaesthetic. Outside a healthcare setting and without supervision, its use can lead to dependence and various physical and psychological consequences.

Some of the ketamine and its metabolites are excreted in the urine. Repeated contact between these substances and the lining of the urinary tract can contribute to inflammation and damage to the bladder.

The layer lining the inside of the bladder acts as a protective barrier against urine. When this barrier breaks down, the tissues can become irritated, inflamed and ulcerated. Over time, thickening, scarring and a loss of elasticity in the bladder wall may also occur.

As a result, the bladder may struggle to expand and store a normal amount of urine. The person then feels the need to go to the toilet constantly, even though they are only able to pass a very small amount.

In the most severe cases, the damage may also affect the ureters and kidneys. For this reason, urinary symptoms associated with ketamine use require medical assessment and should not be treated merely as a temporary nuisance.

What is ketamine-induced cystitis?

Ketamine cystitis is an inflammation of the bladder associated with the use of this substance. It can cause symptoms similar to those of a urinary tract infection, although its cause and treatment are not necessarily the same.

It may also be referred to by other names:

• Ketamine-induced cystitis.
• Ketamine bladder syndrome.
• Ketamine bladder.
• Ketamine-induced uropathy.
• Ketamine cystopathy.
  
  

The term ‘uropathy’ is used when the damage is not limited solely to the bladder and may affect other structures of the urinary tract.

The most characteristic symptoms include frequent urination, urgency, pain when urinating, pain in the lower abdomen and blood in the urine.

Main symptoms of ketamine-induced bladder problems

Symptoms vary from person to person. They may begin as seemingly mild discomfort and gradually become more severe.

Frequent urge to urinate

One of the first signs may be the need to go to the toilet much more often than usual.

The person may urinate repeatedly during the day and wake up several times during the night. Sometimes, they feel an urgent need to urinate, but only a very small amount comes out.

This frequency may interfere with:

• Sleep.
• Work or study.
• Commuting.
• Social life.
• Personal relationships.
• The ability to stay away from home.
  
  

Frequent urination and the need to get up at night are two common symptoms of ketamine-associated nephropathy.

Urinary urgency

Urinary urgency is the sudden onset of an intense urge to urinate that is difficult to delay.

It is not simply a matter of feeling the need to go to the toilet. The sensation can be so strong that the person needs to find a toilet immediately.

When the bladder is inflamed or has lost capacity, it can send signals that it is full even when it contains only a small amount of urine.

Pain or a burning sensation when passing urine

Pain when passing urine, known as dysuria, may feel like:

• Burning sensation.
• Stinging.
• A cutting sensation.
• Pressure.
• Sharp pain.
• Severe pain at the end of urination.

This symptom can be mistaken for a urinary tract infection. However, taking antibiotics without a proper assessment does not reverse the damage caused by ketamine when there is no bacterial infection.

The cause of the symptoms must be assessed through the patient’s medical history and any tests deemed necessary by the healthcare team.

Pain in the bladder or lower abdomen

Inflammation can cause pressure or pain in the area below the navel.

The discomfort may occur when the bladder begins to fill, whilst passing urine, or continuously. Some people also experience pain in the back or sides when there are complications affecting other parts of the urinary system.

Blood in the urine

The presence of blood can make the urine appear pink, red or brown. On other occasions, the amount is so small that it can only be detected through a test.

Blood in the urine always requires medical assessment, even if it has only occurred once or the person thinks they know the cause.

It should not automatically be assumed that it is due to ketamine, as it may also be related to infections, stones or other problems with the urinary tract.

Difficulty controlling the bladder

Urgency and a reduced bladder capacity can lead to involuntary leakage of urine.
Some people begin to:

• Not making it to the toilet in time.
• Leaking urine during the day.
• Wetting the bed at night.
• Avoiding going out for fear of not being able to find a toilet.
• Using incontinence products.
• Excessively reducing the amount of water they drink.

Incontinence is one of the possible symptoms of urinary damage associated with repeated ketamine use.

Passing small amounts of urine

The person may feel the constant need to urinate, but only pass a few drops or a very small amount.

When the bladder wall becomes inflamed, thickens or loses elasticity, its capacity to store urine can be significantly reduced. In advanced stages, this reduction can seriously affect quality of life

How might urinary damage progress?

Ketamine-induced cystitis does not always remain stable. If use continues, the inflammation and damage may progress.

Progression may include:

1. Urgency and frequent urination.
2. Pain or a burning sensation when passing urine.
3. Persistent inflammation of the bladder.
4. Ulceration of the inner lining.
5. Thickening and fibrosis of the bladder wall.
6. Reduced bladder capacity.
7. Incontinence and chronic pain.
8. Affection of the ureters or kidneys.
   
   

Not everyone necessarily goes through all these stages. The course of the condition depends on factors such as the amount consumed, the frequency, the duration of exposure, individual susceptibility and how quickly consumption is stopped and medical attention is sought.

In the most serious cases, complex urological treatments and even surgical procedures may be necessary. The latest medical information warns that some injuries may be permanent and may require reconstructive surgery or, in exceptional cases, removal of the bladder.

Can the bladder recover after stopping ketamine?

Stopping use is the main way to prevent the damage from progressing further.

In the early stages, some people experience an improvement in their symptoms after stopping ketamine. The frequency and pain may gradually decrease if the damage is not yet severe.

However, recovery is not guaranteed. Where fibrosis, significant loss of bladder capacity or upper urinary tract involvement is already present, some of the damage may persist despite stopping use.

The likelihood of improvement depends, amongst other factors, on:

• The severity of the injuries.
• The length of time over which the substance has been used.
• The frequency and quantity.
• Sustained abstinence.
• The presence of renal complications.
• The speed with which care is received.
• Adherence to the prescribed treatment.

Resuming use after improvement can lead to a recurrence of symptoms and a further deterioration. Sustained abstinence is therefore an essential part of both the urological approach and the treatment of addiction.

How is ketamine-induced cystitis diagnosed?

Urinary symptoms can have various causes. For this reason, the diagnosis must be made by a healthcare professional.

It is important to be honest about your ketamine use. Withholding this information may delay the diagnosis or lead to the symptoms being repeatedly mistaken for conventional urinary tract infections.

The assessment may include:

• Consultation regarding fluid intake.
• Physical examination.
• Urinalysis.
• Blood tests.
• Ultrasound scan of the bladder and kidneys.
• Measurement of bladder capacity.
• Urodynamic studies.
• Cystoscopy.
• Additional imaging tests.
  
  

Not all of these tests are necessary in every case. The medical team will select them based on the symptoms and the suspected severity.

Co-ordinated involvement of specialists in urology, mental health and addiction treatment may also be required.

What should you do if urinary symptoms appear?

If you experience pain, urgency, incontinence, excessive frequency or blood in the urine, it is recommended that you:

1. Seek medical advice

It is not advisable to wait for the problem to go away on its own. A medical assessment can rule out infections, stones, blockages and other conditions, as well as determine whether there is any ketamine-related damage.

2. Be honest about your use

Healthcare professionals need to know:

• How long the person has been using the substance.
• How often.
• Approximate quantity.
• When the symptoms began.
• Whether other substances are being used.
• Whether there have been any previous attempts to stop using the substance.

This information helps to ensure that tests and treatment are appropriately targeted.

3. Stopping ketamine use

Continuing to use ketamine may maintain inflammation and contribute to further damage.

Giving up ketamine can be difficult when there is tolerance, a strong craving, or psychological dependence. In such circumstances, it is advisable to seek specialist addiction support rather than attempting to go through the process without help.

4. Do not use ketamine to relieve pain

Ketamine has analgesic effects, and some people return to using it in an attempt to manage the pain caused by the substance itself.

This can create a vicious circle: the medication temporarily relieves the pain, but continues to damage the bladder and may make the problem worse.

5. Do not self-medicate

You should not take antibiotics, anti-inflammatories, strong painkillers or other treatments without professional advice.
The appropriate medication depends on the cause of the symptoms, the severity of the damage and the person’s general state of health.

When should you seek urgent medical attention?

You should seek urgent medical attention if:

• Visible blood in the urine.
• Severe pain in the bladder, abdomen, back or sides.
• Difficulty or inability to pass urine.
• Fever accompanied by urinary pain.
• Persistent vomiting.
• Confusion or general deterioration.
• Loss of consciousness.
• Difficulty breathing.
• Seizures.
• Suspected poisoning or overdose.
  
  

In an emergency, you should call 112.

Managing bladder problems is no substitute for treating addiction. Both issues need to be tackled in a coordinated manner to reduce the risk of continued substance use and the recurrence of injuries.

Addiction treatment and urological care

Where bladder problems co-occur with problematic ketamine use, two simultaneous courses of treatment may be required.

On the one hand, the medical or urology team will assess any urinary tract damage and decide how to treat the symptoms and complications.

On the other hand, a team specialising in addiction can help to:

• Stop using.
• Control the urge to use.
• Identify triggers.
• Address psychological dependence.
• Treat associated emotional problems.
• Prevent relapses.
• Involve the family.
• Maintain long-term abstinence.

How the family can help

The person affected may hide their symptoms out of embarrassment, fear or because they do not want to admit to their drug use.

The family may notice changes such as:

• Very frequent trips to the toilet.

• Constant waking during the night.

• Pain when passing urine.

• Constant concern about finding a toilet.

• Incontinence accidents.

• A reduction in social life.

• Take as required to relieve pain.

• Irritability when ketamine is not available.

• A gradual increase in quantities.

• Expenses that are difficult to explain.

It is best to approach the situation with concern rather than reproach. Phrases such as ‘We’ve noticed that you’re in pain and are constantly going to the toilet’ can make it easier to have a conversation than accusations or threats.

Family members can also seek professional guidance, even if the person affected is not yet willing to start treatment.

You don’t have to face this situation alone.

If you or a family member are struggling with an addiction, the team at CC Adicciones can listen to your situation, answer any initial questions and advise you on the most appropriate treatment.
