3 Cases of Megameatus Intact Prepuce(MIP): Pyramid Procedure / 대한비뇨기과학회지

Megameatus intact prepuce (MIP) is an unusual variant of hypospadias and comprised 3 percent of all hypospadias. Embryologically, maldevelopment of glandular epithelial infolding would appear to be the abnormal process responsible for MIP formation. We have performed the pyramid procedures in 3 patients seen with the MIP variant during 14 months and achieved good results. The pyramid procedure optimizes a safe and simple dissection of the megameatus-urethra, and allows for subsequent reduction and caliber of both with excellent functional and cosmetic results.
