ARTICLE HIGHLIGHTS
Research 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 controversy 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.

In the clinical field, although improvements in medical equipment and technology are in progress, the mechanism of this complication has not been fully discovered and it still cannot be eliminated

In this study, an innovative retractor for phimosis expansion was introduced, which can continuously and gently expand the foreskin in multiple directions and at multiple angles, and relieve the patient's pain.

Research motivation

To design a retractor that can effectively expand the foreskin and reduce patient complications.

Research objectives

To design and manufacture a new type of retractor to verify its effectiveness.

Research methods

A total of 87 children with phimosis were selected. A new type of retractor was designed and manufactured. 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.

Research results

Complications occurred in a small number of children 2 wk after surgery. These difficulties were overcome by performing the foreskin dilation and relaxation treatment with lidocaine cream used for superficial anesthesia. None of the cases had red and swollen foreskins or had difficulty urinating after the treatment. One month after the operation, all patients can fully reveal the glans.

Research conclusions

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.

Research perspectives

The characteristics mentioned above make this innovative retractor suitable for clinical promotion.
