Recurrent UTI Treatment in London

Urinary tract infections that keep coming back are exhausting, and being handed another prescription each time rarely feels like an answer. In men especially, repeated infection often points to something treatable — incomplete bladder emptying, a stone, a narrowing of the urethra, or bacteria sheltering in the prostate. Our consultant urologists assess the pattern of your infections, look for a cause, treat it where one is found, and set out a plan for reducing future episodes without relying on antibiotics indefinitely. Where nothing structural is wrong, we say so plainly and focus on prevention.

What counts as a recurrent UTI

A urinary tract infection is an infection of the bladder, the kidneys or, in men, sometimes the prostate. Most people have one at some point and it settles with a short course of antibiotics. Infections are usually described as recurrent when there have been two or more proven episodes in six months, or three or more in a year.

Recurrence takes two forms. A relapse is the same organism returning soon after treatment, which suggests bacteria survived somewhere the antibiotic could not reach properly — a stone, the prostate, or urine left sitting in the bladder. A reinfection is a different organism arriving weeks or months later. Telling one from the other is far easier when urine has been cultured before each course of antibiotics, so it is worth asking your GP for previous results and bringing them with you.

Urinary infections are uncommon enough in men that a single confirmed episode is usually worth looking into, and repeated episodes almost always deserve a urological assessment. In women, recurrent cystitis is much more common and often has no serious underlying cause, but the pattern still needs understanding before anyone commits to long-term antibiotics.

Symptoms, and the ones that need urgent care

A bladder infection usually causes some combination of:

• burning, stinging or pain when passing urine
• needing to pass urine more often, and more urgently
• passing only small amounts, or feeling the bladder has not emptied
• a dull ache or pressure low in the abdomen
• cloudy urine, or urine with a stronger smell than usual
• blood in the urine (haematuria), which may look pink, red or brown
• in older people, simply feeling unwell, tired or muddled, without much pain at all

Seek medical help the same day if you develop a temperature, shivering or shaking, pain in the back or side, vomiting, or new confusion. These suggest the infection has reached a kidney or the bloodstream, and that needs assessing quickly rather than treating with another repeat prescription. Go to A&E if you become unable to pass urine at all, or if you feel very unwell.

Why infections come back

The bladder clears bacteria mainly by emptying. Anything that leaves urine behind, gives bacteria somewhere to shelter, or weakens the body’s defences can allow infection to return. The usual explanations are:

• Incomplete bladder emptying — most often from an enlarged prostate, a narrowing of the urethra (a stricture), or a bladder that does not contract strongly
• Bacterial prostatitis — infection sitting within the prostate, which many antibiotics penetrate poorly, so the same organism returns once treatment stops
• Stones in the bladder or kidney, which bacteria can settle on and live within
• Catheters, or previous surgery and instrumentation of the urinary tract
• Diabetes, and other conditions or medicines that affect the immune response
• Structural differences such as a urethral stricture, an enlarged prostate, a pouch in the bladder wall (a diverticulum), or urine tracking back towards the kidney
• In women after the menopause, thinning of the vaginal and urethral tissues as oestrogen levels fall

Sometimes a thorough assessment finds nothing structurally wrong. That is a useful result rather than a wasted one, because it changes the plan from hunting for a cause to preventing episodes and using antibiotics more carefully.

How recurrent UTIs are assessed

The consultation begins with the pattern: how many episodes, how far apart, what grew on culture each time, which antibiotics were used and how quickly symptoms settled. Your urinary stream, how completely you empty, any history of stones, catheters or previous urological surgery, and your general health all shape what is worth testing.

Depending on that picture, assessment may include:

• a urine sample sent for culture and sensitivities, ideally taken before any new antibiotic is started
• blood tests, including kidney function and a check for diabetes
• a urinary flow rate, and a bladder scan afterwards to measure what is left behind
• an ultrasound scan of the kidneys and bladder
• flexible cystoscopy — a thin camera passed into the bladder, usually under local anaesthetic in the outpatient clinic
• a CT scan of the urinary tract, where a stone or another structural problem is suspected
• a sexual health screen in younger men, since inflammation of the urethra can produce very similar symptoms

Few patients need all of these. The point of the appointment is to choose the tests that answer the question in your case, and to explain what each is for.

Some people have typical symptoms with repeatedly negative cultures. That does not mean the symptoms are imagined. Bladder pain syndrome, an overactive bladder, prostate-related symptoms and urethral inflammation can all feel like infection, and each is managed differently. If your main difficulty is a poor stream, hesitancy or getting up at night, our page on problems passing urine may be more relevant.

Treatment

Treating the current infection

Antibiotic choice is guided by what has grown on culture and what has worked before, rather than by habit. Courses in men are generally longer than in women, usually at least seven days, and where the prostate is involved several weeks of an antibiotic that penetrates prostate tissue is often required. Completing the course matters, and a repeat sample afterwards is sometimes useful to confirm the urine has cleared.

Treating the reason it keeps happening

Where a cause is found, dealing with it does more than any antibiotic can. That might mean medical or surgical treatment for an enlarged prostate, management of a urethral stricture, removing a bladder or kidney stone, or reviewing a long-term catheter. In many men, improving bladder emptying alone reduces how often episodes occur.

Reducing the chance of the next episode

• drinking enough through the day that urine stays pale
• taking time to empty fully, and passing urine again a minute or two later (double voiding) if emptying is poor
• treating constipation, which affects bladder emptying more than most people expect
• good control of blood glucose if you have diabetes
• for some patients, a low-dose antibiotic taken at night, or a single dose after sex, for a defined period and with review
• methenamine hippurate, which is not an antibiotic, as an alternative for some people
• topical oestrogen for women after the menopause

Cranberry products and D-mannose come up in almost every consultation. The evidence behind them is mixed, they are not a substitute for finding out why infections recur, and they should not delay assessment. Repeated speculative courses of antibiotics without a culture are worth avoiding for a different reason: they encourage resistant organisms and make later infections harder to treat.

When antibiotics are not needed

Bacteria can be present in urine without causing illness. This is called asymptomatic bacteriuria and, in adults who are not pregnant, it usually does not need treating at all. Treating it does not prevent future infections and does encourage resistance. The main exceptions are certain urological procedures where the lining of the urinary tract will be broken, when treatment beforehand is appropriate.

Equally, cloudy or strong-smelling urine on its own, with no pain, no fever and no change in how often you go, is more often a sign of concentrated urine than of infection. Saying so plainly is part of the job, and a normal result is worth having.

Seeing a urologist in London

The Andrology Centre is led by Mr Maj Shabbir, Consultant Urological Surgeon and past National Chair for Andrology at BAUS, alongside Ms Raveen Kaur Sandher, Consultant Urological Surgeon, and Ms Elsie Mensah, Urology Specialist, whose interests include bladder cancer, benign prostate enlargement and prostate diagnostics. All three practise at Guy’s & St Thomas’, named by Newsweek in 2025 as the number one urology service in Europe.

Clinics are held at HCA at The Shard (SE1 9BS), HCA at Canary Wharf (E14 5NR) and HCA at Guy’s Hospital (SE1 9RT). Patients funding their own care do not need a GP referral. Insurers usually do require one, so it is worth checking with yours before booking. You can call +44 7889 318584 between 8am and 4pm, Monday to Friday, email contact@theandrologycentre.co.uk, or use our contact page.

Bringing previous urine culture results and a list of the antibiotics you have taken makes a first appointment considerably more useful.
