Phimosis of the prepuce can be treated without performing a circumcision. The most common and most effective treatment option is the local application ofcorticosteroid ointment. Should this be insufficiently effective, then the constricted ring can be interrupted with two Z-plasties, which is sufficient to expose the glans penis painlessly. No skin is removed. The intervention may be performed under regional anaesthesia on an outpatient basis. In cases where reconstruction of the prepuce is indicated, this can be accomplished with a distally inverted flap of penile shaft skin combined with the application of free skin grafts.
