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]
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 / ).
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]
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]
The general strategy is started with organic scaffolds with ion-binding sites that promote heterogeneous nucleation. Then localized mineralization can be achieved by controlled ion supersaturation on these ion-binding sites. In such a composite material, mineral function as a highly strong and highly wear- and erosion-resistant surface layer ...
The human body consists of biological systems, that consist of organs, that consist of tissues, that consist of cells and connective tissue. The history of anatomy has been characterized, over a long period of time, by a continually developing understanding of the functions of organs and structures of the body.

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 ]
