UTI in Rhodes: Symptoms, Treatment & When to See a Doctor

A urinary tract infection can quickly disrupt a holiday — especially when burning urination, urgency or frequent trips to the bathroom appear suddenly.

If you are currently in Rhodes and think you may have a UTI, the most important question is not simply “Do I need antibiotics?” It is whether the symptoms are likely to come from a lower urinary tract infection, such as cystitis, or whether there are signs that the kidneys or the rest of the urinary system may be involved.

Most uncomplicated lower urinary tract infections can be assessed and treated without hospital admission. However, fever, chills, pain in the side or back, vomiting or feeling significantly unwell require prompt medical assessment.

Burning when urinating, frequent urination, urgency and discomfort low in the abdomen are common symptoms of a lower urinary tract infection.

A medical assessment is particularly advisable if:

• this is your first episode
• symptoms are moderate or severe
• you are male
• you are pregnant or may be pregnant
• you have recurrent UTIs
• you recently took antibiotics
• you have a history of kidney stones
• you have difficulty emptying your bladder
• the diagnosis is uncertain

Seek prompt medical attention if you also have:

• fever or shaking chills
• pain in the side or back below the ribs
• nausea or vomiting
• significant weakness or feeling seriously unwell
• difficulty or inability to urinate
• visible blood in the urine
• rapidly worsening symptoms

Severe illness, confusion, fainting or other signs suggesting sepsis require emergency medical care.

For a life-threatening emergency in Greece, call 112.

This is especially relevant for visitors to Rhodes.

After several hours in the sun, walking around Rhodes Old Town, spending a day at the beach or simply drinking less water than usual, urine may become darker, more concentrated and stronger-smelling.

That alone does not necessarily mean you have a urinary infection.

A UTI becomes more likely when there are symptoms such as:

• burning or stinging when urinating
• frequent urination
• sudden urinary urgency
• passing only small amounts of urine
• pressure or discomfort above the pubic bone
• cloudy urine
• blood in the urine

A useful travel rule

Dark or strong-smelling urine alone → consider dehydration.

Burning + frequency + urgency → possible UTI.

Urinary symptoms + fever, chills or flank pain → seek medical assessment promptly.

A urinary tract infection occurs when microorganisms, most commonly bacteria, infect part of the urinary system.

The urinary tract includes the:

• urethra
• bladder
• ureters
• kidneys

An infection affecting primarily the bladder is commonly called cystitis.

Current European urological guidance distinguishes between a localised UTI, where infection mainly affects the lower urinary tract without systemic symptoms, and a systemic UTI, where fever, chills, flank pain or other signs suggest more extensive infection.

This distinction matters because investigation, treatment and urgency may be very different.

Burning When Urinating

Pain, burning or stinging during urination — medically called dysuria — is one of the most typical symptoms.

Frequent Urination

You may suddenly need to visit the bathroom much more often than usual.

Urinary Urgency

The urge to urinate may become intense and difficult to postpone, even when the bladder contains very little urine.

Lower Abdominal Discomfort

Some people experience pressure, cramping or discomfort immediately above the pubic bone.

Blood in the Urine

A urinary infection can sometimes cause pink, red or blood-stained urine.

However, visible blood in the urine should not automatically be assumed to come from an infection, particularly if it persists after treatment or occurs without typical UTI symptoms.

A bladder infection and a kidney infection are not the same condition.

Symptoms that may suggest kidney involvement or a systemic urinary infection include:

• fever
• shaking or chills
• flank or back pain
• nausea
• vomiting
• marked fatigue
• feeling generally very unwell

These symptoms require more urgent medical evaluation.

Urine testing and urine culture are commonly considered when systemic infection is suspected, with additional investigations or imaging depending on the clinical situation.

UTIs are particularly common in women.

Travel can also change normal routines. Factors may include:

• reduced fluid intake
• long journeys
• delaying urination
• increased sexual activity
• spending long periods away from convenient bathroom facilities

Medical assessment becomes particularly important when:

• symptoms are unusual
• vaginal discharge or irritation is present
• there is fever or flank pain
• infections recur frequently
• previous treatment has failed
• pregnancy is possible
• antibiotics were recently taken

Vaginal infections and sexually transmitted infections can sometimes cause symptoms similar to a UTI, so identifying the exact symptom pattern matters.

Burning, frequency or urgency in a man should not automatically be treated as simple cystitis without assessment.

Possible causes include:

• urinary tract infection
• prostatitis
• urethritis
• sexually transmitted infection
• urinary retention
• enlarged prostate
• urinary stone disease

Pelvic or perineal discomfort combined with urinary symptoms and fever may indicate acute prostatitis and requires prompt medical evaluation.

Blood can occur during a urinary infection, but haematuria has several possible causes.

These include:

• urinary infection
• kidney or ureteric stones
• prostate conditions
• trauma
• anticoagulant medication
• bladder disease
• kidney disease

If visible blood persists after the presumed infection has resolved, repeatedly returns, contains clots or occurs without clear UTI symptoms, further urological evaluation may be required.

Kidney and ureteric stones can sometimes mimic urinary infection.

A stone more commonly causes:

• sudden severe flank pain
• pain travelling towards the groin
• nausea or vomiting
• blood in the urine
• difficulty finding a comfortable position

A lower UTI more commonly causes:

• burning when urinating
• frequent urination
• urgency
• bladder discomfort

However, stones and urinary infection can occur at the same time.

Fever combined with suspected urinary obstruction or stone disease requires urgent assessment because an infected obstructed urinary system can become a medical emergency.

Not everyone with classic symptoms of uncomplicated cystitis requires extensive testing.

However, urine testing becomes particularly useful when:

• symptoms are atypical
• infection is recurrent
• symptoms do not improve
• systemic infection is suspected
• the patient is pregnant
• antibiotic resistance is a concern
• antibiotics were recently used
• the patient is male

A urine culture with antimicrobial susceptibility testing can identify the organism responsible and determine which antibiotics are most likely to be effective.

Whenever possible, a urine sample for culture should be collected before antibiotics are started, especially in recurrent, complicated or higher-risk cases.

Avoid starting leftover antibiotics or medication prescribed to another person without medical advice.

The appropriate treatment may depend on:

• whether the infection is localised or systemic
• age and sex
• pregnancy
• kidney function
• allergies
• previous urine cultures
• antibiotics recently taken
• bacterial resistance
• possible involvement of the kidneys or prostate

Using the wrong antibiotic may fail to treat the infection and can make subsequent diagnosis and culture interpretation more difficult.

If you are otherwise well:

• drink enough water to avoid dehydration
• avoid deliberately holding urine for long periods
• rest if you feel unwell
• avoid excessive alcohol if it worsens urinary symptoms
• monitor for fever, chills, flank pain or vomiting

Drinking extremely large quantities of water is not a substitute for medical treatment.

Cranberry products, supplements or so-called cystitis sachets should also not be relied upon to treat an established bacterial infection.

Recurrent urinary tract infections deserve a different approach from a single isolated episode.

Possible contributing factors may include:

• sexual activity
• menopause
• urinary retention
• enlarged prostate
• kidney or bladder stones
• urinary tract abnormalities
• catheter use
• diabetes
• previous resistant bacteria

Repeated courses of antibiotics without confirming the diagnosis are not always the best long-term strategy.

Depending on the medical history, a doctor may recommend urine cultures and further urological investigation.

A mild lower urinary tract infection does not automatically prevent air travel.

However, flying may not be advisable if you have:

• high fever
• uncontrolled pain
• repeated vomiting
• significant dehydration
• suspected kidney infection
• urinary retention
• significant systemic illness

If you are due to fly and symptoms are significant, medical assessment before travelling is advisable.

If an airline or travel insurer requires medical documentation, a separate Fit-to-Fly assessment may be necessary.

Rhodes Medical Services can arrange assessment for international visitors experiencing urinary symptoms while staying on the island.

Depending on the situation, evaluation may include:

• medical history and clinical examination
• urine testing
• urine culture when indicated
• assessment for kidney infection
• evaluation for urinary stones or obstruction
• urological assessment where appropriate
• medical documentation for travel insurance reimbursement

Patients with straightforward urinary symptoms may initially be assessed by a General Practitioner.

Recurrent infections, urinary symptoms in men, persistent haematuria, suspected kidney stones, urinary retention or more complex urinary problems may require assessment by a Urologist.

Can I Get Treatment for a UTI While on Holiday in Rhodes?

Yes. A doctor can assess your symptoms and determine whether urine testing, prescription treatment or specialist evaluation is required.

Can Dehydration Cause UTI-Like Symptoms?

Concentrated urine caused by dehydration may become darker, stronger-smelling and sometimes irritating. Burning combined with urinary frequency and urgency is more suggestive of a urinary tract problem.

Do I Need Antibiotics for Every UTI?

Not necessarily. Treatment depends on the symptoms, patient characteristics and whether the infection appears localised or systemic. A healthcare professional should determine whether antibiotics are appropriate.

When Should I Worry About a UTI?

Fever, chills, flank or back pain, vomiting, marked weakness, inability to urinate or rapidly worsening symptoms require prompt medical assessment.

Can a UTI Become a Kidney Infection?

Yes. Urinary infection can sometimes involve the kidneys. Fever, flank pain, chills, nausea or vomiting are important warning symptoms.

Should Men See a Doctor for UTI Symptoms?

Yes. Urinary symptoms in men should generally be medically assessed because infection, prostatitis, urinary obstruction, stones and urethritis can produce similar symptoms.

Can a UTI Cause Blood in My Urine?

Yes, but blood in the urine has several possible causes. Persistent or recurrent haematuria should be investigated rather than automatically attributed to infection.

Can I Fly With a UTI?

Many people with a mild lower UTI can travel. However, fever, vomiting, severe pain, suspected kidney infection or significant systemic illness should be assessed before flying.
