The formation of concealed penis The concealed penis is a common congenital developmental abnormality of the penis. The formation of concealed penis is due to the abnormal attachment of the muscle fiber fascial layer of the lower abdominal wall to the penis body, which binds the penis to extend, resulting in the penis skin not developing well and abnormal attachment to the penis body, and the inability to relieve the prepuce, making the penis short in appearance and cone shaped. Clinical symptoms of occult penis The penis is short and cone-shaped in appearance, and pressing the root of the penis in front of the pubic bone can make the penis obviously exposed and enlarged, and the prepuce opening is narrow. The skin of the penis is poorly developed and the total amount is small. Hazards of occult penis Children with occult penis often have narrow foreskin opening, and the glans often cannot be exposed, and those who cannot be relieved after entering puberty will hinder the development of penis. These children are often prone to infection because of the difficulty in cleaning the area. These children also often have short penis appearance, resulting in doubts, depression, low self-esteem and other negative emotions, thus affecting the psychological health of the child. Treatment of occult penis Children with a clear diagnosis of occult penis should have surgery to correct it. Regarding the timing of surgical treatment for occult penis, given the high risk of surgery in infancy and the difficulty of postoperative care; the relatively static penile growth in early childhood, but the difficulty of cleaning, prepuce and glansitis caused by occult penis may affect the normal development of the child’s penis and cause psychological burden to the child and his family; most boys may be concerned about the condition of their genitalia before puberty and try to compare themselves with others, because the penis cannot stick out Most boys may be concerned about their genital condition before puberty and try to compare themselves with others, and because the penis cannot extend, they often mistakenly believe that the penis is too small or poorly developed, resulting in negative emotions such as doubts, depression and self, which cause abnormal sexual psychology. Complications after anaphylactic penis surgery 1. The appearance may be different from the normal form, and the possibility of unsatisfactory appearance after surgery cannot be ruled out; 2. The possibility of penile recession and recurrence of anaphylactic penis after surgery; 3. Postoperative penile swelling and deformation, pain, scarring, bleeding and infection. According to the basic medical view, in principle, all children with a clear diagnosis of occult penis should be treated with phalloplasty. The time of treatment is preferable after preschool age. In case of obesity, it is recommended to lose weight before considering surgery. The main points of post-operative care for occult penis 1. Position: After surgery, the patient should lie flat on the pillow for 6 hours. Because of the increase of respiratory secretions and muscle relaxation under anesthesia, it is easy to cause vomiting and misaspiration. If there is vomiting, please remove the vomit in time, change clean clothes and pants, and need to observe the color of the child’s mouth and lips, if there is cyanosis, phlegm in the throat and breathing difficulty, you need to inform the doctor or nurse immediately. After the operation, the nurse will routinely place your child on cardiac monitoring and oxygen for 6 hours, please be careful not to let your child grab the tube. 2. Diet: No water or food should be taken before waking up from anesthesia, and a little water can be taken 2 hours after surgery. Because of the long-term bed rest, intestinal peristalsis slows down, easily causing constipation, please keep the stool of the child smooth, 3 days after surgery can not force defecation, to avoid excessive force, but the intra-abdominal pressure increases, resulting in wound cracking or bleeding, encourage the child to eat bananas, honey water, fruits, vegetables and other coarse fiber food. 3, wound care: a little urine or light bloody fluid leaking after surgery is normal, if there is a large amount of B blood or B fluid should promptly notify the doctor. Urine discharge is one of the observation points indirectly reflecting the metabolism of anesthetics. If the child has urinated or has not been solved for a long time (8 hours), please inform the nurse in time. Encourage the child to drink plenty of water, urinate regularly, and pay attention to the child’s personal hygiene. From 3 days after surgery, give 2.5% warm salt water (the concentration of 4 kg of warm boiled water plus 1 tael of salt is 2.5%) to sit in the bath 3 times a day for 20-30 minutes each time, insist on about 1 month, and stop the warm salt water bath after the local swelling of the penis has subsided. 4. Pain: usually the most obvious 1-2 days after surgery, please keep the child quiet, strengthen psychological support therapy, divert the child’s attention, avoid the pain caused by the child’s tension and agitation, and reduce the wound bleeding caused by crying. Please inform the physician if the penis is erect in older children, and take oral painkillers and estrogen if necessary.
