Hypospadias Repair

About This Department

 
Pediatric Urology

In hypospadias, the opening of the urethra sits on the underside of the penis. Repair moves it to the tip, straightens the penis and restores a normal appearance.

Hypospadias repair is surgery for boys born with the urinary opening below its normal position at the tip of the penis, often with a downward bend and an incomplete foreskin. The operation builds a new urethral channel to the tip, corrects the bend and reshapes the glans and skin, usually between six and eighteen months of age. Distal hypospadias, near the tip, is repaired in one operation. In a review of 3,368 distal repairs, a fistula, a small leak along the new channel, followed 3.8 percent of tubularized incised plate repairs (Wilkinson and colleagues, Journal of Pediatric Urology, 2012). Proximal hypospadias, near the scrotum, is more complex. In 2,664 boys, complications occurred in 21 percent after two-stage repair and 42 percent after single-stage repair, and results improved in high-volume centers (Babu and Chandrasekharam, Journal of Pediatric Urology, 2021). This page explains types, timing, techniques, hormones before surgery, curvature, risks, catheter care, long-term follow-up, and how families from abroad arrange hypospadias repair at Biruni Hospital in Istanbul.

What hypospadias is


1
Three features
The urinary opening, the meatus, lies on the underside of the penis, anywhere from just below the tip to the scrotum. The penis may bend downward on erection, called chordee. The foreskin is incomplete underneath, forming a hood on top.
Hypospadias develops in the first months of pregnancy, when the tissues that form the urethra do not close fully. It affects about one in 250 to 300 boys and runs in some families.
The foreskin is often used in the repair. Boys with hypospadias should not be circumcised before seeing a pediatric urologist.

Do not circumcise first

Keep the foreskin.

In hypospadias the foreskin provides extra skin that the surgeon may need to build the new urethra, cover it with a protective layer or close the skin underneath, and once it has been removed at a religious or newborn circumcision, the repair becomes harder and may need grafts from elsewhere. Families who plan circumcision for religious or cultural reasons can have it done during the hypospadias repair, when the surgeon decides how much foreskin to keep or remove.

Check with us first. Circumcise later.

Types of hypospadias

Classification by position of the opening
Type Position of the opening Share of cases
Distal, anterior Near the tip, on the glans or just below Most boys, about two thirds
Midshaft Along the shaft About one in six
Proximal, posterior Base of the penis, scrotum or perineum About one in six, most complex
The position of the opening after the skin is released, the degree of bend and the size of the glans and urethral plate together decide the technique.
Did something during pregnancy cause it?
In most boys no single cause is found. Genes, hormones during early pregnancy and, in some studies, low birth weight and assisted conception are linked with higher rates. Parents have done nothing wrong.

Assessment and timing

Checks before hypospadias repair
Check Why When
Examination of both testes Undescended testes with hypospadias need further tests First visit
Chromosome and hormone tests Proximal hypospadias with undescended testes may signal a difference of sex development When indicated
Penile size and glans width Plan the technique and hormone treatment First visit
Kidney ultrasound Only if other anomalies present Selected boys
Repair between six and eighteen months of age is standard. The child does not remember the operation, and the tissues heal well.
Older boys and adolescents can also be repaired successfully, and we also treat adults with previously unrepaired or failed repairs.

Photographs
A side photograph of the erect penis, which parents can take during a diaper change, shows the degree of bend and helps planning.
We discuss the findings and the plan with the family before any decision.

Repair of distal hypospadias

Distal hypospadias techniques, review of 3,368 repairs
Outcome Tubularized incised plate Mathieu flap
Urethral fistula 3.8 percent 5.3 percent
Narrowing of the new opening 3.1 percent 0.7 percent
Appearance of the opening Vertical slit, natural Rounder
The tubularized incised plate repair, also called Snodgrass repair, makes a lengthwise cut in the urethral plate, rolls it into a tube to the tip and covers it with a protective layer of tissue. The Mathieu repair uses a skin flap from below the opening. Both have low complication rates (Wilkinson and colleagues, 2012).
A one-stage repair takes one to two hours and is the standard for most boys with distal hypospadias.
  • Bring the opening to the tip of the glans.
  • Straighten the penis.
  • Reshape the glans and skin for a normal appearance.
Some families choose no surgery for very mild distal forms where the stream and appearance are acceptable.

Very mild forms
When the opening sits on the glans and the boy urinates normally, surgery serves appearance only, and we discuss the option of waiting.

Repair of proximal hypospadias

Proximal repair, 2,664 boys in 26 studies
Approach Complication rate Note
Single stage, foreskin tube 42 percent Remained high despite experience
Two stage, free foreskin graft 23 percent Fewer fistulas and narrowing
Two stage, foreskin flap 20 percent Improved with higher case load
In the first stage, the surgeon straightens the penis and places foreskin as a graft or flap on its underside. Six months later, once it has healed and softened, the second stage rolls this tissue into a new urethra (Babu and Chandrasekharam, 2021).
Why two operations instead of one?
Severe curvature and a short urethral plate leave too little healthy tissue to build a long new urethra in one step. Staging gives the transferred tissue time to establish its blood supply, which halved the complication rate in the meta-analysis. Each stage needs one anesthetic and a short hospital stay.

Testes and sex development
Proximal hypospadias with an undescended testis needs hormone and genetic tests before surgery, to exclude a difference of sex development.

Experience matters

Hypospadias surgery rewards practice.

The meta-analysis found that complications after two-stage repair fell as the number of operations a center performed each year rose, supporting the idea of dedicated hypospadias teams, while single-stage repair of severe forms stayed difficult even in busy centers. Our pediatric urologists perform these operations every week, use magnifying loupes and fine absorbable stitches, and follow each boy through puberty.

Families can fairly put the same question to any team, how many repairs it performs each year and how it follows boys afterward, and a confident team will answer with real numbers and a clear plan for the years until puberty.

Hormones before surgery

Preoperative hormone stimulation, meta-analysis
Study type Effect on complications Quality
Three randomized trials Fewer complications, relative risk 0.36 Moderate
Observational studies No clear difference Low, risk of bias
Side effects Mild and temporary Darker skin, hair, irritability

When we use it

Testosterone given as injections or cream for one to three months before surgery enlarges the glans and penis temporarily and improves blood supply. Randomized trials showed fewer complications, while observational studies did not (Chua and colleagues, Journal of Pediatric Urology, 2017).
1
Our practice
We offer hormone treatment to boys with a small glans or proximal hypospadias, and surgery follows about one month after the last dose.

Straightening the penis

A bend that remains after repair causes problems in adult life. Straightening is checked during surgery with an artificial erection test.

How it is done

  • Releasing the skin often corrects mild bends.
  • Tightening the upper side corrects moderate bends.
  • Lengthening the underside corrects severe bends, sometimes in the first of two stages.

Techniques

Curvature correction
Degree of bend Technique Note
Under 30 degrees Skin release, dorsal plication Most distal cases
30 to 45 degrees Plication or plate mobilization Midshaft cases
Over 45 degrees Ventral lengthening, staged repair Proximal cases

Risks and fistula

Most complications appear in the first year and are fixed with a smaller second operation.
A fistula shows as urine coming out of a second small hole along the shaft. It does not close by itself and is repaired six months after the original operation.
1
Other complications
Narrowing of the new opening or urethra, a pouch along the urethra, separation of the glans, remaining bend and skin irregularities. Each has its own repair.
How will we know if something is wrong after surgery?
Watch the urine stream once the catheter is out. A thin, slow or spraying stream, straining, a second stream from the shaft or swelling during urination need review. We ask families to send a short video of urination at three months and at each follow-up.

The day of surgery

Fasting follows standard rules for children, solids six hours, breast milk four hours and clear fluids one hour before anesthesia.
A typical day
Step Timing Note
Arrival and checks Morning Numbing cream
Anesthesia Parent present at induction General with caudal block
Surgery One to three hours Longer for proximal repair
Recovery Two hours Catheter and dressing
Discharge Same day or after one to two nights Depends on repair

Pain relief

1
Caudal block
A local anesthetic injected near the base of the spine while the child sleeps numbs the area for six to twelve hours after surgery.

Dressing and catheter at home

Caring for the repair at home
Item What to do Duration
Dressing Keep dry, double diaper Until removal at day 3 to 7
Catheter or stent Drains into the diaper Five to ten days
Bathing Short baths after dressing removal From day 5 to 7
Medicines Pain relief, antibiotic, bladder spasm medicine As prescribed
A thin tube, the catheter or stent, drains urine while the new urethra heals and is removed at the clinic. Bladder spasms can cause brief discomfort or leakage around it, and medicine eases them.
Call us if you see
Sign Possible cause Action
No urine for several hours Blocked catheter Call at once
Fever Infection Call the same day
Bleeding soaking the dressing Wound bleeding Gentle pressure, call
Catheter falls out Displacement Call for advice
Mild swelling and bruising of the penis are normal and settle over two to three weeks.
1
Toys and activity
Avoid straddle toys, walkers and bicycles for three weeks.

Long-term follow-up

1
Through puberty
Problems can appear years later as the penis grows, so we review boys at one year, before school, and around puberty, with urine flow tests when they are toilet trained.
Men who had hypospadias repair in childhood urinate standing, have erections and father children in the great majority, particularly after distal repair. Proximal forms need closer follow-up.

Talking with your son

Children ask questions when they notice differences.

Simple, honest answers at each age, that he had a small operation as a baby to make it work well, help a boy feel confident, and older boys can join the follow-up discussions.

Shame has no place here.

For families from abroad


1
Length of stay
Plan for seven to ten days in Istanbul for a one-stage repair, so that the catheter can be removed and the stream checked before the flight home. Fitness to fly follows that check.
Two-stage repairs need two visits about six months apart. Send photographs of the penis from the side and below, any photographs of erections, information on the testes and earlier surgery.
2
After you return home
Follow-up continues by video and urination videos at one, three and twelve months.
One coordinator from the international patients office handles arrangements from the first message through discharge and answers the same WhatsApp number after you return. The office works in English, Arabic, French, Russian, Serbian, Romanian and Spanish and books interpreters for other languages, and it arranges the visa invitation letter, airport transfers, daily transport and accommodation near the hospital. Halal, vegetarian and diabetic meals, a prayer room on site, and a female physician on request wherever the rota allows.
Families planning circumcision at the same time tell us in advance, so that it is built into the plan.
