The foreskin stone is not a kind of stone with kidney stone, gallstone, urethral stone, etc. The foreskin stone is a dirt polymer formed by the long-term accumulation of foreskin scale.
If a person with a long foreskin does not open the foreskin and wash the glans for two or three days, he will find a layer of white things attached to the surface of the glans and the coronal groove. If the foreskin lasts a little longer, it may appear like bean curd residue with a fishy smell. This is foreskin scale. The foreskin scale is formed by mixing the secretion of the foreskin with urine and other dirt. The foreskin mouth of phimosis patients is too small to open, and the foreskin scale will accumulate more and more. The foreskin scale is easy to breed bacteria, making the foreskin often infected and inflamed. Over time, the foreskin stone gradually forms.
Those with foreskin stones are generally phimosis patients, or those with long foreskin who do not open the foreskin for thorough cleaning.
The greatest risk of prepuce calculus is that it may cause canceration of penis hair. The onset age of penis cancer is earlier than that of most cancers, even before the age of 20. More than 90% of penile cancer occurs in people with long foreskin or phimosis, indicating that the occurrence of penile cancer is directly related to foreskin scaling. In China, there are quite a few men with too long foreskin or phimosis, and many people lack the knowledge of physical health. They do not often open the foreskin for cleaning, and do not seek a doctor to perform circumcision, which increases the incidence rate of penis cancer.
