Circumcision is a clinical maneuver that utilizes instruments to expand the foreskin outlet, primarily to improve conditions such as foreskin adhesions. In some patients, circumcision may be performed at the same time. The foreskin is the skin tissue at the periphery of the penis, which is ductile and can be retracted with penile erection, thus revealing the glans and coronal sulcus. If the patient due to abnormal development of the foreskin, local inflammation and other conditions, resulting in adhesion of the foreskin occurs, can not reveal the glans, the coronal groove. At the same time, after the foreskin adhesion, the urine can not be smoothly discharged, may accumulate in the coronal region, inducing local inflammation. In this case, the doctor will perform a circumcision expansion operation. First, use povidone-iodine to disinfect the foreskin, and then use a curved pliers along the opening of the foreskin to deepen the foreskin for dilation, gradually separating the foreskin adhesion. Some patients with obvious foreskin adhesion, or the presence of obvious circumcision, phimosis and other conditions, can be performed at the same time circumcision, remove the excessive length of the foreskin. Patients are advised to go to the hospital and follow the doctor’s instructions for treatment.
