OBJECTIVELiteratures on the development and function of prepuce was reviewed. To compare the merit and demerit of treatment for redundant prepuce by conventional circumcision or by removing the root skin of the penis. To investigate the ideal method and time of treatment for redundant prepuce.

METHODSThe extended length of the penis and the extended skin of penis were carefully measured and the excess skin at the root of the penis was removed from the surface of Colle's fascia. Then the remaining distal skin was drew back to suture to the root of the penis. As for the cases complicated with stenosis of prepuce, longitudinal incision was performed along the constricted area to release stenosis, followed by transverse closure of the wound.

RESULTS110 adult cases of simple redundant prepuce and 40 cases complicated with stenosis were treated by this way. Functional and cosmetic results were achieved without any complications in all cases. All patients were satisfied with the result.

CONCLUSIONSRemoval of the excess skin at the root of the penis should be preferred to the conventional circumcision for treatment of redundant prepuce. The ideal time for intervention is at or after adolescence, when the prepuce has developed maturely. Non-operative methods should be taken to treat phimosis and adherent prepuce before adolescence.
