Bladder Stones

Understanding Bladder Stones
Bladder stones are solid masses formed by minerals in the bladder. They develop when concentrated urine minerals crystallize, typically due to incomplete bladder emptying.

Formation and Development
Bladder stones can range in size and may pass naturally in some cases. However, medication or surgery is sometimes required for larger stones. Untreated bladder stones can lead to infections and other complications.

  • While bladder stones may remain asymptomatic in some instances, they can cause discomfort and urinary issues when they irritate the bladder wall or obstruct urine flow. Common symptoms include:
    • Lower abdominal pain
    • Pain during urination
    • Frequent urination
    • Difficulty initiating or maintaining urine flow
    • Presence of blood in the urine
    • Urine appearing cloudy or unusually dark


  • Bladder stones form when the bladder fails to completely empty, leading to the concentration of minerals in urine and their subsequent crystallization.
  • Infections and underlying conditions affecting bladder function or urinary drainage can contribute to bladder stone development.
  • Common conditions associated with bladder stone formation include:
    • Prostate gland enlargement, which can obstruct urine flow in men (benign prostatic hyperplasia or BPH).
    • Nerve damage, resulting from factors like stroke, spinal cord injuries, Parkinson’s disease, diabetes, or herniated disks, can affect bladder emptying (neurogenic bladder).
    • Inflammation caused by conditions like urinary tract infections or radiation therapy to the pelvis can lead to bladder stones.
    • The use of medical devices, such as bladder catheters, contraceptive devices, or urinary stents, can also contribute to stone formation.

Risk Factors

  • Men, particularly those aged 50 and above, have a higher likelihood of developing bladder stones.
  • Risk factors include:
    • Urinary obstructions that prevent proper urine flow to the urethra, with an enlarged prostate being a common cause.
    • Nerve damage, often associated with conditions like stroke, spinal cord injuries, Parkinson’s disease, diabetes, or herniated disks.
    • Concurrent nerve damage and bladder outlet obstruction further increase the risk of bladder stone development.


  • Bladder stones that remain untreated, even if asymptomatic, can lead to complications, such as:
    • Chronic bladder problems, resulting in persistent urinary difficulties like pain or frequent urination.
    • Recurrent urinary tract infections due to the presence of bladder stones.


  • Preventing bladder stones primarily involves addressing underlying conditions. Here are some preventive measures:
  • Report any unusual urinary symptoms to your doctor for early diagnosis and treatment, reducing the risk of bladder stones, especially with an enlarged prostate or other urologic issues.
  • Stay well-hydrated by consuming an appropriate amount of fluids, particularly water, to dilute mineral concentrations in the bladder.
