Abstract: Objective To analyze the impact of different inner wound dressings on local wound recovery after surgery for concealed penis, and to explore more appropriate wound dressings and bandaging methods after surgery for concealed penis. 
Methods A total of 158 children with concealed penis treated in our hospital  were retrospectively analyzed including the clinical data, postoperative recovery, the first time of changing dressings, and patients′ satisfaction with changing dressings. The patients were divided into three groups according to the application of the inner wound dressings (A. Sterile gauze group; B. Iodophor gauze group; C. Vaseline gauze group). The bleeding, infection, and adhesion in each group were calculated. The effects of different dressings on postoperative complications were analyzed. 
Results The numbers of bleeding and adhesion in group C were lower than those in groups A and B (P＜0.05). There was no difference in the number of infected individuals among the three groups. The mean time of dressing changes was shorter in group C than in groups A and B (P＜0.05). In the three groups, more serious adhesion led to longer time of dressing changes; conversely, less serious adhesion led to short time of dressing change. The patients′ satisfaction with changing dressings was higher in group C （90.2%） than in groups A and B (P＜0.05). 
Conclusion The vaseline gauze-gauze and double-layer compression dressing has the advantages of low cost and significant effect. It effectively reduces children′s pain during dressing changes and is worthy of clinical promotion.
