Urologenzentrum Wien - Hypospadie: Mann hält ein Schild mit der Aufschrift "HELP" vor seinem Unterkörper.

Hypospadias

Hypospadias is a congenital malformation of the penis, where the urethra does not open at the tip of the glans but further down the shaft of the penis or in the area of the scrotum. This malformation can lead to problems with urination and, in later years, with sexual function. Hypospadias is one of the most common urogenital malformations in newborns.

Causes of hypospadias

The exact causes of hypospadias are not fully understood, but it is believed that genetic and hormonal factors play a role. Possible causes include:

  • Genetic predisposition: Hypospadias is more common in some families.
  • Hormonal disturbances during pregnancy that affect the development of the sexual organs.
  • Environmental factors, such as the mother's exposure to certain chemicals during pregnancy, may also play a role.

Symptoms of hypospadias

  • The urethra opens at an abnormal location on the penis, often further down the shaft
  • Abnormal curvature of the penis (chordee)
  • Difficulty aiming the urinary stream when urinating
  • Increased foreskin on the top side of the penis and missing on the underside

Diagnosis of hypospadias

Hypospadias is usually detected during a physical examination immediately after birth. In some cases, additional examinations such as an ultrasound may be performed to ensure that there are no other malformations of the urogenital tract.

Treatment options for hypospadias

  • Surgical correction: In most cases, surgery is recommended to reposition the urethra correctly and correct any existing penile curvature. This surgery is usually performed in the first or second year of life.
  • Postoperative care: After the surgery, careful follow-up care is required to avoid complications and ensure normal function.

Preventive measures for hypospadias

Since the exact causes of hypospadias are not fully known, there are no specific preventive measures. However, it is recommended to minimize risk factors such as exposure to harmful chemicals during pregnancy and to pay attention to a healthy diet and lifestyle.


Common Patient Questions About Hypospadias

There are various surgical techniques for correcting hypospadias, depending on the severity of the case. The most common procedures include the Tubularized Incised Plate (TIP) urethroplasty and the onlay flap technique. The goal of the surgery is to reconstruct the urethra and redirect the urinary stream forward.

A hypospadias is usually surgically treated at the age of 6 to 18 months, as healing is better in young children and the risk of complications is lower. In the case of later diagnosis or more severe forms, the operation can also be performed in later childhood.

Possible complications after hypospadias surgery include fistulas (small holes in the urethra), scarring, strictures (narrowing of the urethra), and rarely infections. A repeat surgery may be necessary in some cases to achieve the desired result.

As a rule, hypospadias does not have a direct impact on fertility. However, in more severe forms of hypospadias that are not treated, there could be problems during sexual intercourse that could indirectly affect fertility. A successful operation, however, corrects the anatomical function completely in most cases.
