hypospadias

What is Hypospadias?

Hypospadias is an abnormality of the penis that affects about one in 150 male babies [3]. It is a congenital condition, meaning it is present at birth. The condition results from abnormal development of the urethra, foreskin, and cavernosal bodies [5].

Characteristics of Hypospadias

In hypospadias, the urethral opening is ectopically located on the ventral aspect of the penis, rather than at the tip [1]. This can cause a range of symptoms, including:

• A partially-formed or hooded foreskin with deficient skin on the bottom side of the penis where the urethra is located [2]
• The urethral opening may be located on the underside of the penis, near the scrotum (penoscrotal hypospadias) [7]

Prevalence and Detection

Hypospadias is a relatively common condition, affecting about 1 in 150 male babies. It is usually detected at birth or shortly thereafter.

Common Signs and Symptoms of Hypospadias

Hypospadias, a congenital condition in males, can manifest through various physical and functional symptoms. Understanding these signs is crucial for early detection and proper treatment.

• Abnormal Urethral Opening: The most distinctive symptom of hypospadias is the abnormal placement of the urethral opening, which is not located at the tip of the penis but somewhere along its length [2][3].
• Problems with Urination: Affected individuals may experience difficulties peeing, including a urine stream that doesn't spray in a normal direction [1].
• Penile Chordee and Hooded Foreskin: Some cases are associated with penile chordee (a downward curve of the penis) and dorsally hooded foreskin, where only the top half of the penis is covered by foreskin, giving it a hooded appearance [6][9].
• Difficulty Directing Urine Stream: In some instances, individuals may find it challenging to control their urine stream, which can be hard to direct and control [8].
• Abnormal Spraying During Urination: The urine stream may not spray in the usual direction, indicating an issue with the urethral opening's location [7].

These symptoms are crucial for identifying hypospadias. Early detection is key to ensuring proper treatment and minimizing potential complications.

Diagnostic Tests for Hypospadias

Hypospadias, a congenital condition where the urethral opening is located on the underside of the penis, can be diagnosed through various tests and examinations.

• Physical Exam: A physical exam by a pediatrician or urologist is usually the first step in diagnosing hypospadias. The healthcare professional will examine the child's genital area to identify the location of the urethral opening, degree of curvature, and appearance of the penis [1][2].
• Laboratory Studies: No laboratory tests have been found to be helpful in the evaluation and management of hypospadias [3]. However, in some cases where a more complex diagnosis is suspected, additional tests such as ultrasound may be recommended.
• Ultrasound: An ultrasound may be recommended for babies who have proximal or complex hypospadias. This test can help confirm the diagnosis and provide information on the severity of the condition [4].
• Evaluation at CHOP: At Children's Hospital of Philadelphia (CHOP), the evaluation for hypospadias will include an exam to identify the location of the urethral opening, degree of curvature, and appearance of the penis. This comprehensive evaluation is essential in determining the best course of treatment [5].

In summary, the diagnostic tests for hypospadias typically involve a physical exam by a healthcare professional, which may be followed by additional tests such as ultrasound if necessary.

Preoperative Hormone Therapy

According to various studies, preoperative hormone therapy (PHT) is used in some cases to increase penile dimensions and vascularity of tissues available for surgical repair [10]. This treatment aims to improve the outcome of surgery by enhancing the blood flow to the penis. However, it's essential to note that not all patients undergo PHT, and its effectiveness can vary depending on individual circumstances.

Types of Hormone Therapy

The most commonly used hormone therapy for hypospadias is testosterone supplementation [4]. This treatment involves administering a specific dose of testosterone to stimulate the growth of the penis. The goal is to increase the size and vascularity of the penis, making it easier to perform surgical repair.

Benefits and Limitations

While PHT can be beneficial in some cases, its use is not universal, and more research is needed to fully understand its effects [2]. Some studies have shown that PHT can lead to improved surgical outcomes, but others have raised concerns about the potential risks and side effects associated with hormone therapy.

Current Recommendations

Most pediatric urologists recommend surgery (hypospadias repair) as the primary treatment for hypospadias, rather than relying solely on drug treatment [5]. However, in some cases, preoperative hormone therapy may be considered to improve surgical conditions. It's crucial to consult with a qualified healthcare professional to determine the best course of treatment for an individual patient.

Differential Diagnosis of Hypospadias

Hypospadias, a congenital anomaly of the male urethra, foreskin, and penis, can be associated with various differential diagnoses. These conditions may present similar symptoms or characteristics, making accurate diagnosis crucial.

• Micropenis: A condition where the penis is smaller than normal, which can be associated with hypospadias.
• Epispadias: A rare congenital anomaly where the urethral opening is on the upper side of the penis, rather than the underside.
• Chordee: Abnormal curvature of the penis, often seen in conjunction with hypospadias.
• Penis hypoplasia: A condition where the penis fails to develop normally, which can be associated with hypospadias.

According to Sparks (2021), when hypospadias is seen on prenatal ultrasound, the differential diagnosis includes micropenis, epispadias, and other conditions [4][8]. Additionally, Upper et al. mention that Congenital Adrenal Hyperplasia can be a diagnosis associated with unilateral or bilateral undescended testis if it's linked to hypospadias [10].

A classification of hypospadias based solely on the position of the urethral meatus is considered simplistic and may be deceptive, as noted by Halaseh (2022) [12]. It's essential to consider various factors when diagnosing hypospadias.
