The protection provided by the foreskin for the glans penis and meatus has been recognized since 1915. In the absence of the foreskin the meatus is exposed to mechanical and chemical irritation from ammoniacal diaper (nappy) that produces blister formation and ulceration of the urethral opening, which eventually gives rise to meatal stenosis (a narrowing of the opening). [1]
A congenital misshaping can result in its narrowing (meatal stenosis), causing a partial or total urinary blockage or the bifurcation of the urinary stream. A urethral blockage can also be caused by foreign material, kidney stones , or bladder stones ( lithiasis ).
The meatus (opening) of the urethra located at the tip of the glans might become subject to meatal stenosis, a condition mostly seen as a late complication of circumcision. It occurs in about 2–20% of circumcised boys [49] [50] and it is rarely seen in uncircumcised men. [51]
Stenosis (from Ancient Greek στενός (stenós) 'narrow') is the abnormal narrowing of a blood vessel or other tubular organ or structure such as foramina and canals. It is also sometimes called a stricture (as in urethral stricture ).

A meatotomy (/ m iː ə ˈ t ɒ t əm ɪ / [1] [2]) is a form of penile modification in which the underside of the glans is split, extending the urinary meatus.The procedure may be performed by a doctor to alleviate meatal stenosis or urethral stricture.
Meatal stenosis, making it more difficult or even impossible to urinate, may also occur. [citation needed] On the non-genital skin, the disease may manifest as porcelain-white spots with small visible plugs inside the orifices of hair follicles or sweat glands on the surface. Thinning of the skin may also occur. [7]
Van Howe realised a study which found that meatal stenosis is much more common in circumcised boys than in intact ones. In the abstract of this study, Van Howe even states that "Meatal stenosis may be the most common complication following neonatal circumcision." [8]
