1.What is penile curvature? As the name implies, when the penis is bent in any direction such as upward, downward or sideways in the erect state, it is called penile curvature. Li Wenji, Department of Urology, Ninth People’s Hospital, Shanghai Jiaotong University School of Medicine 2, what are the causes of penile curvature? (1) congenital hypospadias or supraurethral cleft, abnormal development of the urethral corpus cavernosum or lack of urethral corpus cavernosum, as well as abnormal fibrous bands lead to downward or upward bending of the penis during erection; (2) foreskin ties are too short, pulling the head of the penis to cause downward bending of the penis during erection; (3) penile corpus cavernosum sclerosis, which not only causes penile bending, but also causes erection pain and sexual dysfunction; (4) penile white membrane development (4) abnormal development of the white membrane of the penis, due to uneven development of the white membrane of the penis, one side is too tight, one side is too loose, resulting in upward, downward or lateral bending of the penis. (5) penile trauma, masturbation or excessive force during sex, improper sexual position, resulting in penile injury and rupture of the white membrane, later forming crazy marks, resulting in penile curvature. In addition, bad habits, such as wearing tight underwear so that the penis long-term to the side of the skew. 3.What are the hazards of penis curvature? How to deal with it? (1) penis curvature deformity although in male external genital deformity is relatively rare, but easy to cause erection pain; In addition, when the bending angle is greater than 20 degrees, resulting in difficulties in sexual intercourse, or even can not be inserted, even if inserted will continue to stimulate a local part of the vagina and very easy to cause female dissatisfaction, resulting in the patient and the spouse’s quality of life is reduced. (2) there is no effective drug treatment for penile curvature, so when the penis is bent and stable for more than 6 to 9 months and any of the following conditions need to be surgically corrected: pain is obvious, the angle of curvature is greater than 30 degrees, sexual intercourse difficulties, the woman is not satisfied with the situation. 4.What are the surgical methods of penile curvature? At present, the most effective international surgical treatment of penile curvature are two. The first is, when the penis is long enough to use the “16-point method” to fold and sew the white membrane of the penis from the curved projection to correct the bend; the second is, when the penis is small in length to use the patch to repair the curved part, without affecting the length of the penis under the premise of correction of the bend. Both surgical methods have their strict indications and advantages and disadvantages, and the specific procedure should be chosen according to the patient’s specific situation. The Department of Urology of the Ninth People’s Hospital of Shanghai Jiaotong University School of Medicine is the first department to effectively treat penile curvature in China. 10 years we have treated more than 100 cases of penile curvature with different surgical procedures according to the patient’s condition, filling the gap in China, especially on the basis of the “16-point method” made some improvements, called In particular, we have made some improvements based on the “16-point method”, which is called the “modified 16-point method”, and has obvious effects on various forms of penile curvature and distortion with very large curvature angle, and cases of recurrence after surgery. The surgical method not only leaves only the same surgical traces as circumcision, more beautiful appearance, post-operative correction of bending success rate, patient and spouse satisfaction rate is also very high. 5, penile curvature after surgery patients need to pay attention to what? (1) oral antibiotics for 3-4 days after surgery to prevent infection; (2) 2-4 days after surgery to remove the penile incision dressing, a change of medication; after that, according to the local situation every 2-3 days a change of medication; (3) 2 weeks after surgery, the penis moderate pressure bandage to avoid penile swelling; (4) 1 week to avoid showers, 2 months to avoid sexual life (including sexual intercourse and masturbation); (5) after surgery, if more than bleeding or swelling (6) Do not carry out red light, microwave and ultrashort wave treatment after surgery to avoid penile necrosis.
