Hypospadias

Advanced and less invasive treatments

Hypospadias is a congenital condition in which the urethral opening is located in a different position than usual on the penis. Treatment may be surgical, depending on the characteristics of the hypospadias and its functional and aesthetic impact.

What is it?

Hypospadias is an anomaly in the formation of the penis during gestation that manifests itself, fundamentally, in three ways:

  • The opening through which urine comes out (called the meatus) is often narrow and not at the tip of the penis.
  • The penis has a ventral downward curve, more evident in an erect position.
  • There is a ventral preputial skin defect and dorsal skin excess.

Hypospadias are classified as follows :

  • DistalThese are the most frequent. They occur when the meatus is close to the glans and both the curvature and the skin defect are milder.
  • Media: those in which the malformation is more severe.
  • Proximal: those in which the meatus is located at the base of the penis or even in the scrotum.

In a significant percentage of cases, especially in more severe cases of hypospadias, it can be associated with other abnormalities , the most frequent being:

  • Penoscrotal transpositionIt is an anomaly of the external genitalia in which the scrotal skin originates above the penis.
  • Unilateral cryptorchidism: is the absence of one or both testicles in the scrotal sac.
  • The prostatic utricleThis is an anomaly in the formation of the internal genitalia that frequently occurs in children with severe hypospadias. It consists of the persistence of an embryonic remnant resulting from the formation of the internal genitalia during pregnancy, creating a blind pouch in the posterior urethra. It may become apparent during episodes of urinary tract infection, kidney stones, or when catheterization is difficult in these patients.

Regarding symptoms , the presence of hypospadias is suspected when a pressurized urine stream is directed downwards, ventral curvature is present during erection, and excess skin is present in the dorsal area.

The glans of the child is usually covered by the balanopreputial adhesions, so it is common that the real position of the urinary meatus cannot be accurately determined.

Hypospadias is considered to have multifactorial causes, meaning that genetic factors and multiple environmental factors are involved.

Evaluation by a pediatric urologist is important to identify mild cases, reassure parents, rule out other abnormalities if necessary, and schedule intervention at an appropriate age.

The diagnosis is made through a thorough examination in consultation , in which the following are assessed:

  • The position and size of the meatus
  • The presence or absence of penile curvature
  • The quality and arrangement of the foreskin
  • The numerous abnormalities that are frequently associated with this pathology: webbed penis, penoscrotal transposition, bifid scrotum, cryptorchidism…

In severe hypospadias, a urological ultrasound may be necessary to rule out other associated pathologies.

Hypospadias can be treated with surgery and should be performed by a pediatric urologist specializing in the management of this condition.

Hypospadias treatment is usually done from the age of one year , but the optimal age for this intervention can be individualized according to the severity of the malformation and personal circumstances.

The goal of this treatment is to correct the curvature, bring the opening to the glans, and achieve a good cosmetic result. Different techniques can be used , depending on the characteristics of the condition and the patient. The final assessment, the selection of the best technique for each case, and the planning of one or two procedures are often completed on the day of the surgery.

The surgery usually lasts between one and two hours, depending on the technique used. During the immediate postoperative period, the patient has a urinary catheter to prevent complications and a dressing around the penis that will not be removed until the seventh postoperative day. After the catheter is removed, the patient regains normal continence , and stitches do not need to be removed, as they dissolve on their own within a few days.

After the procedure and removal of the catheter, the patient will need to attend follow-up appointments to assess the aesthetic result, the presence and characteristics of erections, and the urinary stream.

The most frequently described complication in the literature is the appearance of a urethral fistula, which is a small hole in the path of the operated area, through which urine leaks out.

To avoid this complication, all necessary measures are taken to ensure meticulous care of the tissues and protection of the sutures using vascularized flaps, thus reducing the possibility of this complication occurring.

Follow-up care for these patients continues after the procedure, although visits become less frequent, until the child's growth is complete. This allows the pediatric urologist to assess the long-term outcome and ensure that the patient's questions and concerns are addressed.
