Phimosis refers to a tight foreskin which makes it difficult or impossible to completely and easily open the glans. The foreskin is the skin covering the glans. Phimosis may only manifest when the penis is erect (milder cases) or may also be present when it is flaccid.
- Congenital: the foreskin, which is long and narrow in children, fails to undergo the usual widening during pubertal development, remaining narrow;
- Acquired: these causes occur after normal pubertal development. They are generally associated with infective factors: infection of the glans and foreskin (balanoposthitis), which, while healing, result in scar tissue retraction processes affecting the foreskin and leading to phimosis.
The complete or partial impossibility of retracting the foreskin varies in line with the severity of the pathology:
- Mild phimosis: the glans is only difficult to uncover when the penis is erect. It may cause discomfort during sexual relations when the foreskin is retracted downwards, but does not entail hygiene problems;
- Moderate phimosis: even with a flaccid penis, the glans can only be uncovered partially. In such cases, in addition to perturbation of sexual relations, there may be hygiene problems since it is difficult to wash the gland, which may lead to infective complications which worsen the phimosis;
- Severe phimosis: the glans cannot be uncovered, hygiene is compromised and there are frequent infective complications. In the most advanced cases, it may even be difficult to urinate.
Phimosis is a benign pathology which can have severe impact, sometimes significantly limiting the patient’s ability to live a normal life.
The diagnosis of phimosis is very simple and is often made by the patient himself. On examination, the foreskin is found to be narrow and thus the diagnosis is made. In the milder forms in which the phimosis is only manifest with an erect penis, the outcome of the consultation may be ambiguous. In such cases, talking to the patient should clarify the situation.
Circumcision is the most commonly performed procedure. It is carried out using local anesthetic at the base of the penis in a circumferential manner. It involves complete removal of the foreskin.
After the procedure, the glans remains completely uncovered. The procedure has the advantage of being curative in virtually all cases, but has the disadvantage of leaving the glans completely uncovered. After the procedure, sutures that will be absorbed within a few days are usually used. The wound heals within around 2 weeks. It is necessary to wait around 3-4 weeks before resuming sexual activity. Initially, the fresh scar may cause some discomfort, but the use of anti-inflammatory pomades may be helpful in speeding up the resumption of sexual activity. The glans, which remains fully or partially uncovered, will have increased sensitivity due to being in direct contact with the external environment. However, this sensitivity is entirely transitory and disappears as soon as a keratinized (corneal) covering is formed like that on the lips, which reduces the sensitivity. After circumcision, anesthetic or keloid scars may form, which cause psychological issues for the patient, who is not able to engage in normal sexual relations.
