Endogenous stones: These are small stones formed within the acini of the prostate. They have a higher correlation with age. [3] Extrinsic stones: These stones are usually larger and formed due to the reflux of urine into the prostate. [3] The exact mechanism of the development of prostatic calculi is still unclear. [3]
The prostate is covered in a surface called the prostatic capsule or prostatic fascia. [4] The internal structure of the prostate has been described using both lobes and zones. [5] [2] Because of the variation in descriptions and definitions of lobes, the zone classification is used more predominantly. [2]
A calculus (pl.: calculi), often called a stone, is a concretion of material, usually mineral salts, that forms in an organ or duct of the body. Formation of calculi is known as lithiasis ( / ˌ l ɪ ˈ θ aɪ ə s ɪ s / ).
Ejaculation occurs in two stages, the emission stage and the expulsion stage. [4] The emission stage involves the workings of several structures of the ejaculatory duct; contractions of the prostate gland, the seminal vesicles, the bulbourethral gland and the vas deferens push fluids into the prostatic urethra.

Calcification can manifest itself in many ways in the body depending on the location. In the pulpal structure of a tooth, calcification often presents asymptomatically, and is diagnosed as an incidental finding during radiographic interpretation. Individual teeth with calcified pulp will typically respond negatively to vitality testing; te
Bladder stones are small mineral deposits that can form in the bladder. In most cases bladder stones develop when the urine becomes very concentrated or when one is dehydrated. This allows for minerals, such as calcium or magnesium salts, to crystallize and form stones. Bladder stones vary in number, size and consistency.
Corpora amylacea (CA) (from the Latin meaning "starch-like bodies") is a general term for small hyaline masses found in the prostate gland, [1] nervous system, [2] lung, [1] and sometimes in other organs of the body. [3] Corpora amylacea increase in number and size with advancing age, [3] [4] although this increase varies from person to person. [3]
In some prostate cancers, PSMA is the second-most upregulated gene product, with an 8- to 12-fold increase over levels in noncancerous prostate cells. [19] Because of this high expression, PSMA is being developed as potential biomarker for therapy and imaging of some cancers. [ 20 ]
