目的：为临床应用阴茎皮肤和包皮皮瓣修复尿道下裂提供解剖学依据。方法：对8例新鲜阴茎标本，经明茎背钱动脉灌注有色明胶和组织切片观察血管走行和配布。结果：阴茎皮肤和包皮由明茎背浅动脉供应，并且包皮外板和内板的血管是连续的。左、右阴茎背钱动脉之间存在吻合；在真皮网状层和乳头层之间有乳头下层血管网，并由该血管网发分支供应表皮。包皮血管主要配布在包皮内板区和外板区，中间区血管配布最少。结论：用阴茎远侧皮肤和分离展开包皮作带蒂岛状皮瓣具有可行性。
Objective: To provide an anatomical basis for the clinical application of penile skin and preputial flap in the repair of hypospadias. Methods: 8 cases of fresh penile specimens were injected with colored gelatin and histological sections through the artery of penicillium to observe the vascular movement and distribution. Results: The penile skin and foreskin were supplied by the clear stem, superficial arteries, and the vessels of the prepuce and the inner plate were continuous. There is anastomosis between the left and right penile dorsal arteries; there is a sub-nipple vascular network between the dermis reticular layer and the papillary layer, and the epidermis is supplied by the vascular network. The main distribution of preputial blood vessels in the foreskin and outer plate area, the middle area with the least vascular. Conclusion: It is feasible to use the distal skin of the penis and the unclarified foreskin to make the pedicle island flap.
