anterior penis
Introduction
Introduction to the scrotum of the penis The scrotum of the penis is also called the transposition of the penis and scrotum. It refers to the scrotum located above the penis. It is a rare congenital malformation. It is divided into complete and partial 2 types. The scrotum of the penis often merges with the perineal and scrotal urethra. There are also reports of abnormalities in the development of concurrent sex chromosomes and appendix. basic knowledge The proportion of illness: 0.001% - 0.002% Susceptible people: male Mode of infection: non-infectious Complications: Infertility
Cause
Cause of scrotal anterior penis
(1) Causes of the disease
The cause of the scrotal scrotum is unknown, which may be caused by some delays in the development of the penis of the reproductive nodules, and the growth of the labia scrotum bulge in front of it, or in the development of the reproductive nodules and the scrotum scrotum. In this case, the migration of the labia scrotum bulge to the underside of the penis creates an obstacle, causing the penis and scrotum to shift from each other.
(two) pathogenesis
In the scrotum of the penis, the scrotum is divided into scrotum, located in front of the penis. According to the degree of displacement of the scrotum and penis, it is divided into the complete scrotum of the penis and the scrotum of the penis. The former refers to the scrotum completely moved over the penis, the latter scrotum Only partially located above the penis (Fig. 1, 2), without the combined hypospadias, the penis developed normally, without penile curvature and urethral opening.
Prevention
Pre-penis scrotum prevention
The disease belongs to chromosomal diseases, and the cause of chromosomal abnormalities is unclear. It may have certain correlation with environmental factors, genetic factors, dietary factors, and mood and nutrition during pregnancy, so this disease cannot be directly prevented. Regular examination should be done during pregnancy. If the child has a tendency to develop abnormalities, chromosome screening should be done in time, and abortion should be performed in time to avoid the birth of the diseased child.
Complication
Penile anterior scrotal complications Complications, infertility
The disease belongs to congenital chromosomal abnormal disease, and the clinical incidence is very rare. The complications are mainly due to infertility caused by dysplasia, accompanied by abnormal development of other tissues and organs, such as testicular loss, and no Testicular, abnormal vaginal morphology, urethral malformation, etc., for patients with urethral malformations, urinary tract infections may occur due to abnormal urination.
Symptom
Penile anterior scrotal symptoms common symptoms penis abnormal penile short hypospadias
Complete penis anterior scrotum of the penis completely moved behind the scrotum or between the scrotum anus, and the penis itself is normal development, part of the penis anterior scrotum is in the scrotum in the posterior part of the urethra often combined with hypospadias, penis bending, penis short, Anal atresia and other deformities.
Examine
Examination of the anterior scrotum of the penis
Routine line karyotype identification and sex chromatin examination to exclude sex chromosome abnormalities.
Diagnosis
Diagnosis and differentiation of scrotum before penis
According to the typical clinical manifestations of the scrotum above the penis, the diagnosis can be confirmed. It should be checked whether the malformation such as hypospadias is combined. At the same time, attention should be paid to the identification of the scrotal rupture type of hypospadias, routine karyotype identification and sex chromatin examination. Exclude sexual chromosomal abnormalities.
