Bladder stones, which are also referred to as vesical calculus or cystoliths, most often occur when the bladder isn’t completely emptied, and the minerals in the remaining urine—known as concentrated urine—crystallize into hard masses.
There are a variety of factors that may cause this to happen, which we’ll soon explore, but struggling with emptying the bladder isn’t the only reason stones can occur. In some cases there may be an underlying medical condition or infection that is contributing to their formation. Read on to learn more about the most common causes and risk factors of this condition.
1. Prostate Gland Enlargement
All men have something called a prostate gland which is located between the penis and the bladder. It surrounds the urethra, a “thin tube that transports urine from your bladder during urination,” defines Healthline.com.
As they age, many men will develop an enlarged prostate, which the NHS says “can press on the urethra and block the flow of urine from their bladder.” While this is typically treatable, the source indicates that bladder stones can develop in those for whom the treatment is unsuccessful.
