Design and development of a new type of phimosis dilatation retractor for children

Abstract

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. 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.

Novoglan device for treatment of adult phimosis: Novoglan-01 open-label clinical trial on safety, efficacy and tolerability

“…This form of phimosis treatment has been extensively studied and applied over the past three decades and has been effective in 71.1–91.1% of cases with a recurrence rate of up to 29.5% ( 10 , 14 - 17 ). Other methods of conservative treatment include recently developed devices for phimosis treatment, however, data on their application is very limited with some devices being suitable only for patients with low-grade phimosis, who can at least partially retract the foreskin and expose the glans ( 11 , 12 ). Due to higher prevalence of phimosis in children, some methods of phimosis treatment were validated in paediatric populations only and require careful interpretation and further assessment in adults.…”

“…Patients with phimosis, therefore, often wish to trial other methods of treatment before proceeding with circumcision. These methods include preputioplasty, or surgical treatment of phimosis with preservation of the foreskin ( 9 ) or conservative treatments, such as use of corticosteroid creams ( 2 , 10 ) with progressive stretching of the prepuce and application of stretching devices ( 11 , 12 ).…”
