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 / ).

This can occur with or without a mineral imbalance. A common misconception is that calcification is caused by excess amount of calcium in diet. Dietary ...
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.

Uroflowmetry is done to measure the rate of urine flow and total volume of urine voided when the subject is urinating. [51] Abdominal ultrasound examination of the prostate and kidneys is often performed to rule out hydronephrosis and hydroureter. Incidentally, cysts, tumours, and stones may be found on ultrasound.
Calcium is the most abundant mineral in the human body. [3] The average adult body contains in total approximately 1 kg, 99% in the skeleton in the form of calcium phosphate salts. [ 3 ] The extracellular fluid (ECF) contains approximately 22 mmol, of which about 9 mmol is in the plasma . [ 4 ]
