Abstract: Objective: To compare the clinical effects of sleeve circumcision at the base of penis and conventional circumcision in the treatment of redundant prepuce in children.Methods: One hundred and twelve children with redundant prepuce were treated with sleeve circumcision at the base of penis(group A)52 cases,and conventional circumcision(group B)60 cases.The operation time,intraoperative blood loss,postoperative pain time,postoperative complication and postoperative 6-month satisfaction of penile appearance between two groups were compared.Results: The difference of the operation time between two groups had no statistically significant(P< 0.01).The intraoperative blood loss and postoperative pain in group A were better than those in group B(P< 0.01).Conclusions: The effects of sleeve circumcision at the base of penis in the treatment of redundant prepuce in children are good,which is a safe and effective circumcision technology,and has a good application prospect.
