Hypospadias is a congenital birth defect found in male babies, where there are malformations of the male external genitalia. It is a common urological birth defect that is usually treated with surgery. It generally does not cause any pain or difficulty in urination in a newborn. Typically, it is detected by the pediatrician present at the time of birth. Some severe cases are also detected during the fetal ultrasound during the third trimester.
What is Hypospadias?
Hypospadias, a birth defect in male babies, is a condition where the urethra is on the underside of the penis. Urethra, which is the duct for semen and urine, is typically located in the tip of the penis. In general, when babies have a defect in the foreskin or the opening of the penis, it is termed as hypospadias. Although it occurs as an isolated malformation, it is also associated with other congenital defects in some children. Based on the location of the urethra, hypospadias is classified as anterior, middle and posterior type. Of the three, the anterior type of hypospadias is very common and is reported in about 50% of the cases.
How Common is Hypospadias in Newborns?
Hypospadias is a very common congenital defect that occurs to one in every 150 -250 male births. In India, with over more than 80,000 cases per year, it is the second most common urological birth condition. In the United States, every 5 boys out of 1000 born have this common malformation.
Causes of Hypospadias in Babies
Hypospadias is caused due to a defective folding of the urethral lobes during week seventh and fourteenth of the pregnancy. There are many factors that cause this defect in children.
- Majority of the cases are due to a genetic predisposition.
- Having a baby at a higher age, especially after 35 years, is a risk factor for the development of this congenital disorder.
- Intake of hormones such as progesterone during pregnancy can cause hypospadias. Unfortunately, this may inhibit the production of testosterone in the foetus. Many times doctors prescribe hormones for conception and to sustain the pregnancy thus increasing the chances of hypospadias.
Signs and Symptoms of Hypospadias
Hypospadias can be easily identified with its dislocated urethra on the underside of the penis. In this condition, the hole for urinary output is not on the tip of the organ. Other symptoms of the condition include,
- A urinary stream that is directed in multiple directions, depending upon the location of the urethra. This is a typical symptom in older boys who have a more severe form of the malformation.
- A penis that is curved downwards termed as chordee. An erect penis looks slightly bent and drooping.
- The additional foreskin on the tip of the penis, leading to a hooded appearance.
- The tip of the penis looks different from normal with a drooping appearance.
Types of Hypospadias
There are primarily three types of hypospadias. The classification is based on the location of the displaced urethra as,
Also known as the sub-coronal type or the anterior type. In this condition, the opening of the urethra is located at the dial end of the male genitalia, near the head of the penis. It is the most common type of hypospadias and is the type associated with only minor defects. Coronal hypospadias belongs to this category of malformations where the meatus is in the coronal region of the penis. Other subtypes in this category are glandular and sub Coronal hypospadias.
In this subtype of hypospadias, the urethral orifice is in the middle of the penis. This type accounts for twenty to thirty percent of cases.
Proximal hypospadias, also known as the posterior hypospadias, has the urethral opening in towards the bottom end of the penile shaft. Some severe forms of this type have the urethral meatus in the perineum or the scrotum and based on the location classified as penoscrotal, scrotal or perineal. Disorders of sexual development are common with this form and require extensive reconstruction.
Complication of Hypospadias
Usually, hypospadias in a newborn does not cause any pain or difficulty in urination. But, if untreated it may cause difficulty in sexual intercourse in the later stages of life. Milder cases with a slightly curved penis can cause an abnormal spraying pattern while urination.
How can Hypospadias be Diagnosed?
It can be detected through an ultrasound of the baby during the third trimester of pregnancy. It is slightly visible during the early phase of the second trimester in the anomaly scan but does not provide a clear-cut diagnosis. Most of the cases are, however, missed during pregnancy and is only detected on the birth of the child. A paediatrician present during or immediately after the delivery, who checks for any congenital defects, usually diagnoses it based on the physiological symptoms.
Hypospadias Treatment for Babies
Usually, the aim of any hypospadias repair procedure is to straighten the penis as much as possible and reconstruct the urethral opening close to its original position. Minor cases of hypospadias are usually left untreated and are only operated upon for cosmetic reasons.
For more advanced cases, the only treatment option available is to reconstruct the penis through surgery. The best age at which your child can be operated is between three months and eighteen months. During the reconstruction surgery, the doctor uses some foreskin to extend the length of the urethral tube.
What Happens before Operating the Child?
Before the operation, your child is asked to run through a couple of blood tests to check for any blood-related disorders or clotting disorders.
What Happens During the Operation?
During the operation, there should not be any kind of infection like cold, diarrhoea, etc. Babies are given anaesthesia on an empty stomach for the operation. Many parents who are anxious about their child often ask the doctor how long does hypospadias surgery take? The time taken changes from case to case, depending on the location of the meatus and the curvature of the penis.
What Happens after the Operation?
After the successful completion of the surgery, the baby is discharged the next day after some post-operative care in the form of keeping the penis area dry and away from infection is important to avoid any complications. A catheter for urine output is usually connected for a week or two.
Are there any Risks of Surgery?
The hypospadias surgery in infants come with some minor risk factors like a,
- The formation of a fistula – an orifice through which urine leaks. This can form many days or months after the operation.
- Hematoma – clotting of blood in the penis.
- Narrowing of the urethral tube due to scarring- This can result in the build-up of pressure on the nearby organs like bladder, kidney and prostate. This also restricts the free passage of urine.
- Curvature of the penis can reoccur in some cases.
- A small fluid-filled bulge in the urethra
1. Do All Babies with Hypospadias Require Surgery?
Mild cases of hypospadias do not require reconstructive surgery. However, due to curvature issues, some parents opt for surgery for cosmetic purposes. Severe cases, with symptoms that hamper their regular life would require repair through surgery.
2. When Should the Surgery be Scheduled?
Ideally, the surgery is scheduled between the age of six months and eighteen months of age. General anaesthesia is given during the procedure, and it is safe to administer it after six months of age. hypospadias repair operation during the puberty period can cause erection issues and can be associated with complications like the formation of a fistula.
3. What Kind of Care My Baby Need after Operation?
Post-operative care for babies involves keeping the penis area dry and away from infections. The operated area is covered by a large bandage for a week or two to protect from any kind of infection. A catheter is usually attached to facilitate the urine expulsion. Care must be taken to keep all these intact. Use of diapers must be done carefully after taking guidance from the nurses.
4. Are There any Alternatives Available Other than Surgery?
No, surgery is the best and only option to reconstruct the malformation.
5. When will My Baby’s Penis Look Like Other Boys?
Usually after six months of surgery, the penis of the baby will start looking like normal. The exact result of the surgery differs from one patient to another.
Hypospadias is a developmental issue of the urethra, and one can take solace in the fact that it does not indicate any kidney related issues with the excretory system. Minor cases often do not require corrective surgery, and the severe cases can be rectified within the first two years of birth.
