Bladder stones and bladder tumours are different conditions affecting the urinary bladder. Bladder stones are hard mineral deposits that develop within the bladder, while bladder tumours are abnormal growths arising from bladder tissue.
Both conditions may cause blood in the urine, urinary discomfort or changes in urination. However, their causes, diagnostic evaluation and treatment approaches differ. A bladder tumour may be benign or malignant, and appropriate investigations are needed to establish its nature.
Dr. Prakash Sankapal, a urologist in Navi Mumbai , provides urological consultations at NewEra Hospitals, Vashi, and JP Kidney Care, Ulwe. Clinical assessment helps determine appropriate investigations and management options.
What Are Bladder Stones?
Bladder stones, also called vesical calculi, are hard deposits formed when minerals in urine crystallise within the bladder.
They commonly develop when the bladder does not empty completely, allowing urine to remain in the bladder for an extended period.
Some bladder stones are discovered incidentally, while others cause pain, urinary symptoms or infection.
Important: Small stones may sometimes pass naturally, but many bladder stones require treatment. Identifying the underlying cause is important for reducing the risk of recurrence.
What Causes Bladder Stones?
Bladder stones may form because of incomplete bladder emptying, urinary abnormalities or other medical conditions.
Possible contributing factors include:
- Enlarged prostate: Benign prostatic hyperplasia may obstruct urine flow and prevent complete bladder emptying.
- Bladder dysfunction: Neurological conditions may affect bladder contraction and emptying.
- Urinary tract infections: Certain infections may contribute to stone formation.
- Foreign materials: Long-term catheters or other foreign materials in the bladder can sometimes contribute to stone development.
- Urinary obstruction: Narrowing of the urethra or other obstructions may interfere with normal urine drainage.
- Urinary stone migration: Stones formed in the kidney may travel through the ureter into the bladder.
Bladder outlet obstruction may be related to prostate enlargement and other prostate diseases , while narrowing of the urinary passage may occur with urethral stricture disease .
What Are the Symptoms of Bladder Stones?
Bladder stones may cause symptoms when they irritate the bladder lining or interfere with urine flow.
- Pain or discomfort in the lower abdomen.
- Burning or pain during urination.
- Frequent urination.
- Sudden urgency to urinate.
- Interrupted or weak urinary stream.
- Difficulty emptying the bladder.
- Blood in the urine.
- Recurrent urinary tract infections.
Similar symptoms may occur with a urinary tract infection or other bladder conditions. Symptoms alone cannot establish the diagnosis.
How Are Bladder Stones Diagnosed?
Evaluation involves reviewing urinary symptoms, medical history and relevant investigations.
Tests may include:
- Urine examination: May identify blood, infection or other urinary abnormalities.
- Ultrasound: Commonly used as an initial imaging test to detect bladder stones.
- CT imaging: May be considered when further information is required.
- Cystoscopy: Allows direct examination of the bladder using a camera-equipped instrument.
- Uroflowmetry: May help assess urinary flow.
- Post-void residual test: Measures urine remaining after bladder emptying.
The European Association of Urology recommends evaluating the cause of bladder stone formation alongside the stone itself.
Read the EAU guidelines on bladder stones for further clinical information.
What Are the Treatment Options for Bladder Stones?
Treatment depends on stone size, composition, symptoms, bladder function, infection status and the underlying cause.
1. Observation
Selected small stones that have migrated into the bladder may pass naturally. Observation is considered only when appropriate after clinical assessment.
2. Medical Management
Some selected uric acid bladder stones may be suitable for dissolution through medically supervised urinary alkalinisation.
Medicines cannot dissolve every type of bladder stone.
3. Transurethral Cystolithotripsy
Transurethral cystolithotripsy is an endoscopic procedure in which an instrument is passed through the urethra into the bladder.
The stone is fragmented using suitable equipment, and fragments are removed. This is a commonly used procedure for adults with bladder stones.
4. Percutaneous Cystolithotripsy
In selected circumstances, the bladder may be accessed through a small opening in the lower abdomen to remove or fragment stones.
5. Open Bladder Stone Surgery
Open surgery may be considered for very large stones or when other procedures are unsuitable.
Treatment may also need to address the cause of incomplete bladder emptying to reduce future stone formation.
What Is a Bladder Tumour?
A bladder tumour is an abnormal growth arising from tissues within the bladder.
Bladder tumours may be benign or malignant. Most bladder cancers arise from the urothelial cells lining the bladder.
A tumour seen on imaging or cystoscopy requires appropriate assessment. Tissue examination is generally needed to determine the tumour type and other relevant pathological features.
Important: Bladder stones and bladder tumours are different conditions. A bladder stone is not the same as cancer, and finding a bladder tumour does not by itself establish the final cancer diagnosis.
What Factors May Increase Bladder Cancer Risk?
Certain exposures and medical factors are associated with increased bladder cancer risk.
- Smoking: Tobacco use is an important recognised risk factor.
- Occupational exposure: Certain industrial chemicals may increase risk.
- Age: Bladder cancer is more common in older adults.
- Previous treatment: Certain chemotherapy medicines or pelvic radiation may increase risk.
- Chronic irritation: Selected chronic bladder conditions may contribute to particular cancer types.
- Previous bladder cancer: A history of bladder cancer increases the risk of recurrence.
These factors do not mean that an individual will necessarily develop bladder cancer.
What Are the Symptoms of a Bladder Tumour?
Blood in the urine is an important possible symptom of bladder cancer.
Other possible symptoms include:
- Visible or microscopic blood in the urine.
- Frequent urination.
- Urinary urgency.
- Burning or discomfort during urination.
- Recurrent urinary symptoms without an established cause.
- Pelvic or lower abdominal discomfort in some cases.
Early bladder cancer may cause painless blood in the urine. However, these symptoms may also be caused by non-cancerous conditions.
Medical advice: Visible blood in the urine should be medically evaluated, even if it occurs only once or is not accompanied by pain.
How Are Bladder Tumours Diagnosed?
Evaluation is based on clinical history, urine investigations, imaging and endoscopic examination as indicated.
1. Urine Examination
Urine tests may identify blood, infection or other abnormalities.
2. Urine Cytology
Urine cytology examines urine for abnormal cells. It may be useful in selected cases, particularly when high-grade disease is suspected.
A negative cytology result does not exclude bladder cancer.
3. Ultrasound or CT Imaging
Imaging may help evaluate the urinary tract and identify some bladder abnormalities. CT urography may be appropriate in selected patients.
4. Cystoscopy
Cystoscopy allows the urologist to inspect the bladder lining using a camera-equipped instrument.
It is a key investigation for suspected bladder tumours.
5. Biopsy or TURBT
Tissue may be obtained through biopsy or transurethral resection of bladder tumour (TURBT).
Histopathology helps establish the diagnosis, tumour grade and relevant staging information.
Further information: EAU guidelines on bladder cancer diagnosis .
What Are the Treatment Options for Bladder Tumours?
Management depends on whether the tumour is cancerous, its type, grade, stage and the patient’s overall medical condition.
1. Transurethral Resection of Bladder Tumour
TURBT is an endoscopic procedure used to remove visible bladder tumours and obtain tissue for pathological examination.
It is an important part of diagnosis and treatment for many non-muscle-invasive bladder cancers.
2. Intravesical Treatment
Selected patients may receive medicines placed directly into the bladder after TURBT.
Treatment may include intravesical chemotherapy or BCG immunotherapy, depending on cancer characteristics and guideline-based risk assessment.
3. Radical Cystectomy
Radical cystectomy involves removal of the bladder and creation of an alternative urinary drainage pathway.
It may be considered for muscle-invasive bladder cancer or selected high-risk situations.
4. Bladder-Preserving Treatment
Selected patients with muscle-invasive bladder cancer may be considered for combined treatment approaches involving surgery and chemoradiotherapy.
5. Systemic Treatment
Advanced or metastatic bladder cancer may require systemic therapies such as chemotherapy, immunotherapy or other appropriate cancer treatments.
Selection requires specialist oncology and multidisciplinary assessment.
Treatment pathways differ significantly between non-muscle-invasive and muscle-invasive bladder cancer. No single approach is suitable for everyone.
Bladder Stones vs Bladder Tumours
Although these conditions can produce overlapping urinary symptoms, their medical evaluation and treatment differ.
| Feature | Bladder Stones | Bladder Tumours |
|---|---|---|
| Nature | Mineral deposits within the bladder | Abnormal tissue growth |
| Common concern | Pain, urinary symptoms and obstruction | Blood in urine and possible malignancy |
| Assessment | Imaging and evaluation of bladder emptying | Cystoscopy, imaging and tissue examination |
| Treatment | Observation or stone removal when indicated | Depends on pathology, grade and stage |
| Follow-up | Underlying cause and recurrence risk | Disease-specific surveillance and treatment |
What Are the Possible Risks of Bladder Procedures?
Bladder stone removal and bladder tumour procedures have possible complications.
Depending on the procedure, these may include:
- Bleeding or blood in the urine.
- Urinary tract infection.
- Pain or burning during urination.
- Temporary difficulty passing urine.
- Bladder or urethral injury.
- Need for temporary catheterisation.
- Need for another procedure.
- Anaesthesia-related complications.
TURBT may also carry a risk of bladder perforation. Longer-term outcomes depend on the underlying diagnosis and treatment performed.
Why Is Follow-Up Important?
Follow-up requirements depend on the diagnosed condition.
After Bladder Stone Treatment
- Evaluation of the underlying cause of stone formation.
- Assessment of urinary flow and bladder emptying.
- Stone analysis where appropriate.
- Imaging or investigations in selected patients.
After Bladder Tumour Treatment
- Review of histopathology results.
- Risk-based follow-up cystoscopy.
- Urine cytology in selected patients.
- Imaging when clinically indicated.
- Further treatment or surveillance depending on disease characteristics.
Bladder cancer can recur after treatment, so following an individualised surveillance plan is important.

Frequently Asked Questions About Bladder Stones and Tumours
No. Bladder stones are mineral deposits, while bladder tumours are abnormal tissue growths that may be benign or malignant.
Bladder stones often form when the bladder does not empty completely. Prostate enlargement, urinary obstruction and bladder dysfunction may contribute.
Some small stones may pass naturally, particularly stones that have migrated into the bladder. Many stones formed within the bladder require active treatment.
Yes. Bladder stones may irritate the bladder lining and cause bleeding. Blood in the urine can have other causes, including tumours, and should be evaluated.
No. Some bladder tumours are benign. However, a suspicious bladder growth requires evaluation and usually tissue examination to establish its nature.
Blood in the urine, sometimes without pain, is an important symptom. Urinary urgency, frequency or discomfort may also occur. These symptoms do not always indicate cancer.
Evaluation may include urine tests, imaging and cystoscopy. Tissue examination through biopsy or TURBT helps establish the diagnosis.
TURBT stands for transurethral resection of bladder tumour. It is an endoscopic procedure used to remove visible tumour tissue and obtain samples for pathological examination.
Follow-up is generally important, particularly after bladder cancer treatment. Surveillance may include cystoscopy, imaging or other investigations according to disease risk.
