Symptoms and Causes of Urinary Bladder Stones

When the urinary bladder is not completely emptied after urination, there can be a buildup of minerals. The minerals present within the liquid turn into crystals when the leftover urine eventually becomes concentrated. These cause the development of urinary bladder stones, also called vesical calculus or cystoliths. While the stones are small, sometimes they will pass out of the body in the course of time. The bladder stones can remain stuck to the wall of the urinary bladder or ureter in other cases. This leads to the stones gathering more mineral crystals and becoming larger over time. The urologists in Kolkata remove the bigger urinary bladder stones.

There can be only one stone or a group of stones, which can be either spherical or irregular in shape. The size of some stones can be really large and some can be so small that they are rarely visible to the naked eye.


There can be no symptoms of urinary bladder stones at first. There are symptoms if the stone irritates the urinary bladder. The symptoms include:

  • There can be discomfort or pain in the penis for males.
  • There can be frequent urination.
  • There can be much delay in starting a stream during urination.
  • There can be a pain in the lower stomach area.
  • There can be pain and discomfort when urinating.
  • There can be blood in the urine.
  • There can be cloudy or abnormally dark urine.


After urinating, if urine is left in the urinary bladder, stones start to grow. This is often the result of an underlying medical condition that stops the urinary bladder from completely emptying when using the toilet.

The following are some of the conditions that stop the bladder from fully emptying, according to the urology doctors in Kolkata.

  • Neurogenic urinary bladder: If there is any damage to the nerves that run between the urinary bladder and nervous system, the bladder may not be fully empty.

  • Prostate enlargement: There is sometimes a pressure of an enlarged prostate gland on the urethra. This can cause a disruption in flow, leaving some urine in the urinary bladder.

  • Medical devices: If catheters or other medical devices move to the urinary bladder, this can be a major factor in the development of urinary bladder stones.

  • Kidney stones: The kidney stones can grow into bladder stones if they migrate down the ureters and do not pass out of the body.

  • Urinary bladder diverticula: In the urinary bladder, pouches can develop. The pouches can hold urine if they grow to a large size and this prevents the urinary bladder from being fully emptied.

  • Cystocele: If the urinary bladder wall becomes weak and drop down to the vagina in women, this can affect the flow of urine from the urinary bladder.
