Prostate Stones: Causes, Symptoms, Association with Prostatitis, and Treatment

Prostate stones, or prostatic calcifications, are a common phenomenon frequently detected during examinations such as computed tomography or ultrasound in men seeking medical care [1]. Despite their frequent detection, the clinical significance of these formations has long been a subject of debate. However, modern research shows that prostatic stones can play a significant role in the development and course of various prostate diseases, particularly chronic prostatitis and related symptoms.

What Are Prostate Stones (Calcifications)?

Prostate stones are hard mineral deposits that form inside the prostate gland. They can vary in size and shape, located both in the ducts of the gland and in its parenchyma. Their frequent detection during routine examinations, such as ultrasound or CT, indicates the widespread prevalence of this condition among the male population [1]. Although their presence is not always accompanied by pronounced symptoms, understanding their nature and potential impact on prostate health is extremely important for urologists and patients.

Causes of Prostatic Stone Formation

The exact mechanisms of prostatic stone formation are not fully understood, but it is believed that they form as a result of chronic inflammation, infections, stagnation of prostatic secretion, or duct obstruction. These factors can lead to the crystallization of calcium salts and other minerals, as well as the calcification of cellular detritus or secretion clots. Prostatic stones are often found in patients with pre-existing prostate diseases, indicating their possible connection with pathological processes in the organ.

Symptoms and Association with Chronic Prostatitis

Prostatic stones can significantly affect the course of chronic prostatitis and men's quality of life. Studies show that the presence of prostate stones not only prolongs the duration of unpleasant symptoms but also reduces the effectiveness of antibacterial therapy in patients with chronic prostatitis [1]. This means that even with adequate infection treatment, stones can serve as a reservoir for bacteria or sustain the inflammatory process, preventing complete recovery.

• Exacerbation of Lower Urinary Tract Symptoms (LUTS): Patients with prostatic stones often experience more pronounced LUTS, such as frequent urination, nighttime urges, difficulty initiating urination, a weak urine stream, and a sensation of incomplete bladder emptying. Some studies report that a moderate number of stones is associated with more severe LUTS [1].
• Chronic Pelvic Pain: Chronic pelvic pain in men is often misdiagnosed as prostatitis [2]. It is important to understand that prostatic stones can exacerbate this pain. Chronic pelvic pain can manifest in very diverse ways and affect not only the pelvic area but also other parts of the body [8]. This condition requires a comprehensive diagnostic approach that rules out serious urological, neurological, or colorectal diseases [2].
• Reduced Treatment Effectiveness: As mentioned earlier, stones can reduce the effectiveness of antibacterial therapy, leading to relapses and a prolonged course of the disease [1].

Diagnosis of Prostate Stones and Related Conditions

The diagnosis of prostatic stones is usually uncomplicated and is performed using imaging methods. The most common and effective ones are:

• Ultrasound Examination (US): Transabdominal and transrectal ultrasound are the primary methods for detecting prostate stones [1]. They allow determining the size, number, and localization of calcifications.
• Computed Tomography (CT): CT also frequently detects prostatic stones, especially if the examination is performed for other indications [1].

In addition to detecting the stones themselves, additional methods can be used to assess the general condition of the prostate gland and urinary system:

• Urodynamic Analysis: Assessment of bladder and urethral function [1].
• International Prostate Symptom Score (IPSS): Subjective assessment of LUTS severity [1].
• Prostate-Specific Antigen (PSA) Test: To rule out prostate cancer [1].
• Prostatic Secretion Analysis: To detect inflammation and infection [1].
• Pathological Examination of Prostate Tissue: In some cases, may be required to clarify the diagnosis [1].

In the presence of chronic pelvic pain or other nonspecific symptoms, the diagnostic approach should be comprehensive and include the assessment of pelvic floor muscle dysfunction, myofascial pain syndromes, and psychosocial distress, as these conditions frequently overlap [2, 8].

Treatment and Management Approaches

Treatment of prostatic stones is most often aimed at relieving associated symptoms and managing underlying conditions such as chronic prostatitis and LUTS. Direct removal of stones is not always required and is considered on an individual basis if they cause significant obstruction or are a source of recurrent infections.

• Drug Therapy: Since stones can reduce the effectiveness of antibacterial therapy in prostatitis [1], the doctor may adjust the treatment regimen, possibly increasing the course duration or changing drugs. Anti-inflammatory agents, alpha-blockers to improve urination, and other medications to alleviate LUTS are also prescribed.
• Chronic Pelvic Pain Management: In the presence of chronic pelvic pain, especially if it is associated with pelvic floor muscle dysfunction or myofascial syndromes, a multidisciplinary approach is necessary [2, 8]. This may include physical therapy, psychological counseling, lifestyle modifications, and other methods. Acknowledging and validating both the physical and psychological distress of the patient are paramount to building trust and confidence, which is the cornerstone for self-care and effective management of chronic pelvic pain [2].
• Observation: In cases where stones do not cause symptoms or their impact is minimal, active surveillance may be recommended.

It is important to remember that successful treatment requires an individual approach and close cooperation between the patient and the physician. A comprehensive assessment of the condition allows for the development of the most effective strategy for managing prostatic stones and related diseases.
