Bladder stones are hard masses of minerals in your bladder. Bladder stones develop when urine in your bladder becomes concentrated, causing minerals in your urine to crystallize. Concentrated, stagnant urine is often the result of not being able to completely empty your bladder.
Symptoms: Some people with bladder stones have no problems — even when their stones are large. But if a stone irritates the bladder wall or blocks the flow of urine, signs and symptoms can develop. These include: Lower abdominal pain; In men, pain or discomfort in the penis; Painful urination; Frequent urination; Difficulty urinating or interruption of urine flow; Blood in your urine; Cloudy or abnormally dark-colored urine.
Treatment: Bladder stones are often removed during a procedure called a cystolitholapaxy (sis-toe-lih-THOL-uh-pak-see). A small tube with a camera at the end (cystoscope) is inserted through your urethra and into your bladder to view the stone. Your doctor then uses a laser, ultrasound or mechanical device to break the stone into small pieces and flushes the pieces from your bladder.
