Penile entrapment is a birth defect that can be seen at birth. However, the reality shows that many cases are detected very late, due to confusion with the manifestation of foreskin stenosis and lack of parental attention. Penile burying should be treated early to avoid effects as the child gets older.1. What is penile depression?
Penile retraction, also known as "penis entrapment", is a birth defect. If left untreated, penile inclusions can cause urinary effects such as recurrent UTIs, fibrous balanitis, and obstruction. Treatment of penile depression is always combined with treatment of foreskin stenosis in children.2. Recognizing penis inclusions in children
The sign of "burying the penis" is that the penis is small, short due to deep sinking into the pubic area, the body of the penis is dropped behind only the skin tube covering the penis.
In penile inclusions, the shaft of the penis and glans are buried in the foreskin, which is continuous with the scrotum and/or abdominal wall, and thus does not protrude from the prepubic skin. When touching, only the skin tube is seen (the skin of the penis is sunken like a screw) but the penis is not visible inside. Only when the penis is erect or pressed by hand, does the shaft of the penis come out and retract while releasing the hand. When the penis is buried, the child will find it very difficult to urinate.

Attach a thread to the distal part of the glans, pulling the penis forward for easier manipulation. Penile peeling
Peeling off the penis to the pubic base with scissors or electric knife. Insert a feeding tube during the removal of the penis to avoid damage to the urethra. Control the bleeding carefully. Deep fixation
Stitch the Buck fascia layer to Dartos at the base of the penis with 02 buttons that do not dissolve or dissolve slowly at the 3 o'clock and 9 o'clock positions, suture carefully, avoiding the urethra.
