Key facts

Bladder stones at a glance.

The essentials, in plain English - what they are, why they form, and how they are treated in the UK today.

  • What they are

    Calculi that form in, or migrate into, the urinary bladder. Also known as vesical calculi.

  • Two big categories

    Primary (endemic) stones from childhood dietary deficiency, and secondary stones from bladder outlet obstruction, stasis or infection.

  • The usual driver

    In UK adults, bladder outlet obstruction from benign prostate enlargement is the most common cause.

  • Composition

    Uric acid, calcium oxalate, struvite (infection), cystine and mixed stones - composition guides prevention.

  • How they present

    About half are silent. When symptomatic - suprapubic pain, blood in the urine, LUTS and recurrent UTIs.

  • Definitive treatment

    Endoscopic cystolitholapaxy plus, crucially, treatment of the underlying cause to prevent recurrence.

Why this guide matters

Stones are the symptom, not the disease.

Three principles run through everything that follows - and they shape how modern UK urology treats bladder stones today.

  • Half are silent

    Around 50 percent of bladder stones are found incidentally on imaging - a good reason to look harder in men with LUTS or recurrent UTIs.

  • Endoscopy is the workhorse

    Modern cystolitholapaxy - usually with a holmium or thulium laser - clears most bladder stones as a day case.

  • Treat the cause, or they recur

    Removing the stone without addressing BPH, stricture, catheter dependence or neurogenic bladder simply resets the clock.

How the diagnosis is made

From first symptom to a clear plan.

The steps a UK GP or urologist will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Urinalysis, MSU and culture

    Dipstick for blood, nitrites and leucocytes, plus a mid-stream urine sample to identify infection and any urease-producing organisms.

  2. 02

    Assessing

    Bladder ultrasound

    A non-ionising first-line scan - picks up most bladder stones and gives a post-void residual volume in the same sitting.

  3. 03

    Assessing

    Plain X-ray KUB

    Around 80 percent of bladder stones are radiopaque and visible on a plain film of the kidneys, ureters and bladder.

  4. 04

    Confirming

    CT KUB

    The gold-standard imaging - confirms number, size and density of stones and screens the upper tracts for co-existing calculi.

  5. 05

    Confirming

    Flexible cystoscopy

    The definitive diagnostic test - visualises the stone, the bladder mucosa and the prostatic urethra, and often enables treatment at the same time.

  6. 06

    Preparing

    Underlying cause workup

    Uroflowmetry, post-void residual and urodynamics identify obstruction, poor detrusor function or a neurogenic bladder driving the stones.

  7. 07

    Preparing

    Stone analysis and metabolic panel

    Composition analysis, 24-hour urine, serum calcium, urate, oxalate and citrate for recurrent or metabolic stone-formers.

Typical timeline: a first visit to a settled plan in a few weeks.

Symptoms

What bladder stones actually feel like.

Suprapubic pain, blood in the urine, LUTS and recurrent infection - with a few classic features worth spotting early.

  • Suprapubic pain

    A dull ache or sharp discomfort over the lower abdomen - often worse at the end of urination.

  • Visible or microscopic blood

    Haematuria is common. Any visible blood in the urine deserves urgent urology assessment.

  • Lower urinary tract symptoms

    Frequency, urgency, hesitancy, intermittency and terminal dribbling - overlapping with, and often blamed on, prostate disease.

  • Sudden stop of stream

    A stone can ball-valve into the bladder neck, cutting off flow mid-stream. Relief often comes with a change of position.

  • Recurrent urinary infection

    Struvite stones harbour bacteria - a common pattern is repeated UTIs that clear on antibiotics but never fully settle.

  • Dysuria

    Burning during urination - especially when infection is present or a stone is irritating the bladder trigone.

  • Retention

    Acute or chronic urinary retention when a stone blocks the bladder outlet - a common trigger for first presentation.

  • Red flag - rupture or fistula

    Rare but serious - a neglected large stone can perforate the bladder or fistulate to bowel or vagina.

Treatment

How bladder stones are treated in the UK.

Endoscopic cystolitholapaxy first, concurrent BPH surgery where needed, and a prevention plan built around the underlying cause.

  • Transurethral cystolitholapaxy

    The workhorse - a cystoscope, a lithotripter (mechanical, pneumatic, electrohydraulic or laser) and fragment retrieval. Day-case for stones under about 2 cm.

  • Holmium or thulium laser

    Modern laser platforms fragment or dust stones of almost any composition. Moses pulse-modulation shortens theatre time and reduces retropulsion.

  • Percutaneous cystolithotomy

    A suprapubic port to remove very large or hard stones - useful when the urethra will not accept a rigid scope, or alongside abdominal surgery.

  • Open cystolithotomy

    Reserved for very large, dense or multiple stones where endoscopic clearance is impractical. Rare in modern UK practice.

  • Concurrent BPH surgery

    TURP, HoLEP, UroLift or Rezum treats the obstruction driving stone formation - often done in the same anaesthetic as stone removal.

  • Extracorporeal shockwave

    ESWL is selectively used for small, fragmentable bladder stones in patients unfit for anaesthesia.

  • Neurogenic bladder management

    Clean intermittent catheterisation, intradetrusor botulinum toxin and, in selected cases, bladder augmentation address the underlying stasis.

  • Prevention plan

    Hydration, dietary adjustment by stone type, urine acidification or alkalinisation, and long-term treatment of any residual obstruction or infection.

Multidisciplinary care

Complex stone disease is best managed by a team - urology, a specialist LUTS or BPH nurse, interventional radiology and, where relevant, spinal cord injury and neuro-urology services all play a part.

A quiet reminder

This guide is for information, not medical advice.

Your GP or urologist knows your history and imaging and can tell you which parts apply to you. If in doubt, get seen.

Red flags

When bladder stones need urgent attention.

Most bladder stones are treated electively. These are the situations where waiting is not safe - and a specialist opinion is needed the same day.

  • Acute urinary retention

    A painful, distended bladder that will not empty is a urological emergency - go to A&E for catheterisation.

  • Frank haematuria

    Visible blood in the urine always warrants urgent urology review to exclude bladder cancer alongside stone disease.

  • Sepsis from infected stones

    Fever, rigors, low blood pressure or confusion with a known stone is a urological emergency - immediate hospital care.

  • Bladder rupture

    Sudden severe abdominal pain, an inability to pass urine and a rigid abdomen - rare, catastrophic, and needs surgery.

  • Recurrent, treatment-resistant UTI

    Repeated infections despite appropriate antibiotics should trigger imaging for an occult stone or foreign body.

  • Long-term indwelling catheter

    Encrustation and stone formation are common - regular changes and imaging are essential.

  • Neurogenic bladder

    Spinal cord injury, spina bifida and multiple sclerosis raise the risk substantially - low threshold to image.

  • Rapidly worsening LUTS

    A sudden change in stream, frequency or urgency in a man with known BPH may signal a new bladder stone.

  • Migrated ureteric stone

    A stone that has passed from the kidney can lodge in the bladder or grow there - always image the upper tracts too.

Living with it

A treatable condition, with a clear plan.

Four things make the biggest difference to long-term outcomes - good hydration, addressing the root cause, planned cystoscopic follow-up and diet tailored to your stone type.

A quiet reminder

Fix the cause and the stones stop coming back.

A stone removed today, in a bladder that still cannot empty, is a stone that will form again. That is the whole prevention story in one sentence.

  1. 01 Hydration

    Drink to a pale urine

    Two to three litres of fluid a day dilutes crystal-forming solutes and lowers the recurrence risk.

  2. 02 Root cause

    Treat the obstruction

    Removing the stone without treating the prostate, stricture or neurogenic bladder is a recipe for recurrence.

  3. 03 Follow-up

    Cystoscopy at review

    A check cystoscopy after treatment confirms complete clearance and inspects the bladder lining.

  4. 04 Diet

    Match diet to stone type

    Uric acid stones favour alkalinising, purine-limited diets. Struvite needs infection control. Cystine needs high fluids and alkalinisation.

Frequently asked

Everything we get asked about bladder stones.

Quick answers on causes, imaging, cystolitholapaxy, laser treatment and preventing recurrence.

  • What are bladder stones?

    Bladder stones, or vesical calculi, are crystallised mineral deposits that form in the urinary bladder or migrate into it from the kidneys. In UK adults they almost always signal an underlying problem - most commonly bladder outlet obstruction from an enlarged prostate, a neurogenic bladder, a long-term catheter or chronic infection.

  • What causes bladder stones?

    Adult bladder stones are usually secondary - anything that stops the bladder emptying properly lets urine sit, concentrate and crystallise. Common triggers are benign prostatic enlargement, urethral stricture, neurogenic bladder, bladder diverticula, indwelling catheters, foreign bodies and migrated ureteric stones. Primary or endemic stones from childhood dietary deficiency are rare in the UK.

  • What do bladder stones feel like?

    Around half are silent and are picked up incidentally. When symptomatic, people describe suprapubic pain that worsens at the end of urination, blood in the urine, a stream that suddenly stops (often improving with a change of position), recurrent urinary infections and lower urinary tract symptoms such as frequency, urgency, hesitancy and terminal dribbling.

  • How are bladder stones diagnosed?

    The pathway starts with a urine sample and culture, then a bladder ultrasound and often a plain X-ray. A CT KUB is the most accurate imaging test, and flexible cystoscopy gives the definitive diagnosis - and usually allows treatment in the same visit. Uroflowmetry and urodynamics then look for the underlying cause.

  • How are bladder stones treated?

    Most stones are cleared endoscopically by cystolitholapaxy - a cystoscope is passed into the bladder, the stone is fragmented with a laser or lithotripter, and the pieces are removed. Very large or hard stones may need a percutaneous or, rarely, open approach. Treating the underlying obstruction - often with prostate surgery such as HoLEP, UroLift or Rezum - is essential to prevent recurrence.

  • Can bladder stones come back?

    Yes, and they will if the underlying cause is not addressed. Recurrence is common in men with untreated BPH, patients on long-term catheters and those with neurogenic bladders. A prevention plan built around treating the cause, hydration, dietary adjustment by stone composition and long-term follow-up is essential.
