Phimosis

Definition of Phimosis
Phimosis is tightness of the prepuce (foreskin) of the penis that prevents the retraction of the foreskin over the glans. The condition is usually congenital but it may be the result of an infection.


Description of Phimosis
True phimosis - that is, not just non-retractability - may rarely be a primary and congenital anomaly, but is much more commonly secondary to repeated attacks of infection that cause scarring and narrowing of the preputial ring.

Difficulty with voiding and ballooning of the prepuce are the commonest reasons for patients seeking treatment, though recurrent bacterial infections (balano-posthitis) may also occur.
