Prostate Stones

Prostate stones are calcifications that form within the prostate gland.  They are common and often found incidentally on imaging studies like CT.  This condition, also known as prostatic calculi, can range from being symptomless to causing significant discomfort and impacting a man’s quality of life. We will discuss the causes, symptoms, diagnostic methods, and treatment options for prostate stones.

Causes of Prostate Stones

The exact causes of prostate stones remain somewhat unclear, but they are thought to be related to age-related changes within the prostate gland itself.  Prostate enlargement can cause secretions within the gland to become trapped, eventually hardening into calcifications or stones. Chronic inflammation or infections within the prostate, known as prostatitis, may also contribute to the development of these stones.

Symptoms and Diagnosis of Prostate Stones

Many men with prostate stones do not experience any symptoms, making this condition often detected incidentally during examinations for other prostate issues. However, when symptoms do occur, they can include urinary problems such as difficulty starting urination, weak urine flow, frequent urination, and discomfort during urination or ejaculation.

To diagnose prostate stones, healthcare providers typically rely on imaging tests. The most common diagnostic tool is a transrectal ultrasound (TRUS), which provides detailed images of the prostate gland and can reveal the presence of calcifications. Other imaging techniques, including X-rays and CT scans, may also be used to aid in the diagnosis of prostate stones.

Imaging and Detection Techniques for Prostate

Transrectal Ultrasound (TRUS)

Transrectal Ultrasound (TRUS) is important in the imaging of prostate stones. This procedure involves the insertion of an ultrasound probe into the rectum, offering a close and detailed view of the prostate gland. TRUS is particularly adept at identifying calcifications within the prostate, making it an invaluable tool in the diagnosis of prostate stones. The high-resolution images produced allow healthcare providers to assess the size and number of stones, which is helpful for determining the most appropriate treatment approach. TRUS is favored for its non-invasiveness, precision, and ability to provide immediate results.

X-ray Imaging

Although less commonly used today for the direct detection of prostate stones due to its limitations in sensitivity compared to other modalities, X-ray imaging can still play a role. Plain abdominal X-rays can sometimes reveal larger prostate stones, especially when they are dense enough to be visible. However, the use of X-rays has largely been superseded by more advanced imaging techniques that offer greater detail and specificity.

Computed Tomography (CT) Scan

CT scans provide a more comprehensive view of the prostate and the urinary tract compared to X-rays. This imaging technique uses a series of X-ray measurements from different angles to produce cross-sectional images of the body. CT scans are particularly useful in cases where more detailed information is needed about the stone’s size, location, and the potential involvement of surrounding tissues. Although not as commonly used as TRUS for prostate stones, CT scans can be important in planning treatment for complicated cases or when other conditions that mimic the symptoms of prostate stones need to be ruled out.

Magnetic Resonance Imaging (MRI)

Magnetic Resonance Imaging (MRI) of the prostate is another advanced imaging technique that can be used in the evaluation of prostate stones, though its use is less common for this specific purpose. MRI offers excellent soft tissue contrast and can provide detailed images of the prostate gland and surrounding structures without using ionizing radiation. This technique can be particularly useful in complex cases where it’s crucial to differentiate prostate stones from other potential prostate conditions, such as tumors or abscesses.

Treatment Options for Prostate Stones

Treatment for prostate stones largely depends on the severity of symptoms. In many cases, where the stones are small and not causing significant symptoms, no specific treatment may be required. However, for men experiencing discomfort or urinary problems due to the stones, several treatment options are available.

Medications to improve urine flow and reduce symptoms are often the first line of treatment. Alpha-blockers, for example, can help relax the muscles around the prostate and bladder neck, improving urine flow. Antibiotics may be prescribed if there is an underlying infection contributing to the formation of stones.

In more severe cases, surgical intervention may be necessary to remove the stones. Transurethral resection of the prostate (TURP) is a procedure where a portion of the prostate is removed to alleviate symptoms. Laser therapy is another option, where lasers are used to break up the stones, making them easier to pass during urination.


Prostate stones, while often symptomless, can cause discomfort and impact a man’s life when symptoms do present. Understanding the causes, recognizing the symptoms, and being aware of the diagnostic and treatment options are crucial steps in managing this condition.

Advances in imaging techniques have greatly improved the detection of prostate stones, allowing for more effective treatment and management. If you suspect you may be experiencing symptoms related to prostate stones, consult with a healthcare provider for an accurate diagnosis and appropriate treatment plan.
