BACKGROUND Phimosis is one of the most common diseases in children.Early selection of appropriate treatment for phimosis in children is beneficial to the development of their reproductive organs and significantly improves the prognosis of phimosis in children.Although traditional circumcision is the most widely used,it has many disadvantages,including postoperative bleeding and incision infection,pain,obvious scars on the surgical incision,and unsatisfactory appearance.In addition,there is much contro-versy regarding treatment options and timing at home and abroad.Surgical procedures such as circumcision and cerclage for children with excessively long foreskin will greatly affect the normal life of children after the operation.Young children need general anesthesia,but this anesthesia carries a great risk.AIM To design a new children phimosis dilatation retractor for children phimosis.METHODS The children phimosis was dilated with an elastic dilation frame,in order to expand the foreskin mouth and expose the penis head,and after that,the phimosis was cured.RESULTS A new type of phimosis dilatation retractor was designed,which can gently dilate the prepuce at multiple angles and in multiple directions at the same time.It has obtained the national patent for clinical application.CONCLUSION The phimosis dilatation retractor based on the principle of elastically expanding the prepuce can achieve the purpose of expanding the phimosis.The clinical application shows that the effect of the children phimosis retractor is significant,which is worth promoting.
