Prostate stones are classified as primary (true) and secondary (false). i.e. migrated to the prostatic section of the urethra and kidneys and bladder. At present, this classification of prostate stones is practically not used. However, there is undoubtedly a rational grain in this classification: if the first condition is chronic, then false stones are urgent, leading to acute urinary retention.
If fifty years ago true prostate stones were rare, now the situation is the opposite, which is the “merit” of modern medicine.
What causes prostate stones?
Normally, the secretory sections of the prostate gland are lined with a single-layer smooth or cylindrical epithelium (depending on the stage of secretion). The excretory ducts are lined with multi-row plasmatic epithelium, which becomes transitional in the distal sections. In case of obstruction in men (mainly elderly), concretions (spherical, up to 2.5 mm in diameter) consisting of proteins and calcium salts can be found in the secretory sections of the prostate gland.
The reason for the violation of the passage of prostate secretion can be caused by both the development of prostate adenoma nodes and inflammation. In the presence of an infectious agent, stones can become an ideal defense for the microorganism, sometimes completely inaccessible to antibacterial drugs.
When examining the composition of prostate stones, their identity with bladder stones is noted. Such prostate stones are formed in the distal parts of the gland (lined with transitional cell epithelium) due to urine reflux into the prostate gland (often after previous interventions - TUR or incision of the prostate gland, trauma). Such stones are also often colonized by microorganisms, covered with a biological film and become a source of chronic infection.

Prostate Stone Diagnosis
Prostate stones are well visualized by ultrasound, CT, and sometimes by survey urography. In combination with anamnestic data, the results of microscopic and bacteriological examination of prostate gland secretion and ejaculate, Doppler mapping of the pelvic organs, and histological examination of biopsies, it is possible to diagnose the presence of a bacterial inflammatory process.
It is important to note that prostate volume and serum PSA levels are indistinguishable between patients with and without asymptomatic prostate stones.

Treatment of prostate stones
TUR of the prostate gland to eliminate all stones is anatomically impossible. If prostate stones are present in combination with IVO, it is advisable to conduct adjuvant antibacterial treatment before TUR.
