Pediatric Urology (incl. Hypospadias): A Comprehensive Patient Guide

1. Definition and Medical Identity

Pediatric urology is a specialized medical field focused on diagnosing and treating urinary tract and genital disorders in children, with hypospadias repair (urethral reconstruction) being a primary surgical procedure. It corrects a congenital birth defect where the urinary opening develops on the underside of the penis rather than at the tip.

The term hypospadias derives from the Greek words hypo (under) and spadon (rent or fissure). It represents a structural deficiency in the development of the male anterior urethra, ventral prepuce, and erectile tissues. Surgical interventions fall under the domain of pediatric urological surgery and reconstructive surgery. The ultimate clinical goal is to establish a straight penis during erection, create a functional urinary channel extending to the tip of the glans penis, and achieve a natural appearance, ensuring optimal voiding and future reproductive health.

2. The Underlying Condition or Need

Hypospadias is a developmental anomaly occurring during early fetal development where the urethral fold fails to fuse completely, leaving the urethral opening positioned along the underside of the penile shaft. Left untreated, severe forms can impair normal standing urination, cause penile curvature during erection, and potentially affect future sexual and reproductive function.

During normal fetal development between the 8th and 14th weeks of gestation, male hormone signals drive the fusion of the urethral folds from the base of the penis forward to the glans. In hypospadias, this fusion process arrests prematurely. As a consequence, three classic anatomical features emerge: an abnormally located urethral meatus (urinary opening), a ventral penile curvature known as chordee, and a deficient ventral foreskin creating a bonnet-like preputial hood dorsal to the glans.

According to epidemiological data summarized in the EAU/ESPU Guidelines on Paediatric Urology (2023), hypospadias affects approximately 1 in every 200 to 300 live male births. If left untreated, severe proximal defects force individuals to sit while voiding to avoid spraying urine, while severe chordee can prevent penetrative intercourse in adulthood due to marked ventral tethering. Furthermore, a narrow urinary opening can cause chronic urinary outflow obstruction, raising bladder pressures and increasing the long-term risk of urinary tract infections.

3. How the Treatment Works — Mechanism

Hypospadias repair works through surgical reconstruction designed to straighten the penis and construct a new urinary channel extending to the tip of the glans. Surgeons mobilize local tissue or skin grafts to rebuild the missing urethral length, realign curvature, and reposition the skin to achieve normal anatomy and function.

The physiological and anatomical mechanism of repair relies on four sequential operative steps: orthoplasty, urethroplasty, glansplasty, and skin closure. First, orthoplasty eliminates ventral tethering. The surgeon releases abnormal fibrous tissue along the ventral shaft or performs a dorsal plication of the tunica albuginea (the fibrous envelope of the erectile bodies) to achieve complete penile straightening.

Second, urethroplasty constructs the neourethra (new urinary channel). The primary modern technique, the Tubularized Incised Plate (TIP) or Snodgrass procedure, involves incising the longitudinal midline of the urethral plate to widen it, followed by tubularization over a soft stent using fine absorbable sutures (6-0 or 7-0 polyglactin). To safeguard against postoperative urine leakage, a well-vascularized interposition layer—such as a dartos vascular flap or tunica vaginalis graft—is tucked directly over the new suture line. Finally, glansplasty wraps the glans tissue around the neourethra to reconstruct a natural conical tip, while preputial skin is reconfigured or reconstructed via scrotoplasty and circumcision-like skin closure.

4. Types and Variations

Surgical techniques for hypospadias vary according to the position of the urethral opening and the presence of penile curvature. Procedures range from single-stage tubularized incised plate repair for distal cases to multi-stage graft procedures for severe posterior defects, with surgical choice dictated by anatomical severity and tissue availability.

Hypospadias classification is determined by the anatomical location of the meatus after correcting penile curvature (orthoplasty):

• Distal (Anterior) Hypospadias: Glanular, coronal, or subcoronal openings. Accounts for approximately 60% to 70% of all cases.
• Middle (Midshaft) Hypospadias: Distal penile, midshaft, or proximal penile openings. Represents roughly 20% of cases.
• Proximal (Posterior) Hypospadias: Penoscrotal, scrotal, or perineal openings. Accounts for 10% to 15% of cases and is frequently accompanied by severe chordee and small penile size.

Procedure Type	Target Defect Severity	Surgical Approach / Technique	Primary Advantages	Clinical Limitations
TIP (Snodgrass) Repair	Distal to select proximal defects	Incision of urethral plate with tubularization over stent	High cosmetic success; natural vertical meatus; versatile	Requires adequate urethral plate quality
Mathieu (Flap) Repair	Distal cases without chordee	Perimeatal vascularized skin flap folded glanularly	Low stricture risk; avoids urethral incision	Horizontal slit meatus; cosmetic limitations
MAGPI Repair	Glanular or subcoronal without chordee	Meatal advancement and glanuloplasty without flap	Outpatient; rapid recovery; no urinary catheter needed	Limited applicability; risk of meatal regression
Onlay Island Flap	Middle to proximal defects	Preputial vascular flap bridged to existing plate	Avoids circumferential graft; single stage	Technical complexity; risk of flap necrosis
Two-Stage Repair (Bracka)	Severe proximal with severe chordee	Stage 1: Chordee release & buccal graft; Stage 2: Tubularization	Low stricture rates in severe anatomy; excellent skin supply	Requires two separate operations 6 months apart

5. Who the Treatment Is For — Indications

Hypospadias repair is indicated for male infants born with an abnormally placed urethral meatus, ventral penile curvature, or incomplete foreskin development. Clinical guidelines recommend performing the repair between 6 and 18 months of age to maximize tissue healing and minimize psychological impact prior to toilet training.

Specific clinical indications established by the American Academy of Pediatrics (AAP) and the European Association of Urology (EAU) include:

• A misplaced urethral opening preventing a forward-directed, standing urinary stream.
• Penile curvature (chordee) exceeding 15 to 20 degrees, which poses a future risk of painful or difficult intercourse.
• Meatal stenosis or narrowing that creates high voiding resistance.
• Parental concern regarding significant anatomical divergence or incomplete preputial skin cover.

The optimal age window of 6 to 18 months leverages rapid infantile tissue recovery, reduced wound disruption from early mobilization, and lack of genital memory. Diagnostic workup involves a meticulous physical exam. In proximal hypospadias accompanied by unilateral or bilateral cryptorchidism (undescended testes), genetic and endocrine evaluations (chromosomal karyotyping and hormone profiling) are mandatory to rule out Disorders of Sex Development (DSD).

6. Who the Treatment Is NOT For — Contraindications

Hypospadias repair is contraindicated in infants with severe active infections, uncorrected bleeding disorders, or high surgical risks associated with general anaesthesia. Newborn circumcision is strictly contraindicated in affected infants, as foreskin tissue is frequently required for urethral and skin reconstruction during the definitive surgical repair.

Detailed clinical contraindications include:

Absolute Contraindications

• Neonatal Circumcision: Performing routine circumcision at birth destroys the preputial hood skin necessary for vascularized flap creation or skin closure during repair.
• Unmanaged Disorders of Sex Development (DSD): Reconstructive surgery must be deferred until comprehensive genetic, endocrine, and multidisciplinary evaluations determine the definitive gender assignment and anatomical plan.
• Severe Uncorrected Coagulopathies: Active bleeding disorders that preclude safe surgical hemostasis.

Relative Contraindications

• Severe Microphallus: An extremely small glans or shaft tissue volume increases complication rates; procedure should be delayed until hormonal pre-treatment increases tissue size.
• Active Cutaneous or Systemic Infection: Local severe diaper dermatitis or systemic viral illnesses require resolution prior to elective surgery under anaesthesia.

7. Alternatives and Clinical Comparison

Non-surgical observation serves as the main alternative for mild distal hypospadias without penile curvature, where urinary function remains entirely normal. When surgical correction is required, single-stage repairs are preferred for distal cases, whereas multi-stage reconstructions are used for severe posterior anomalies to optimize anatomical and long-term outcome parameters.

For mild distal defects (glanular or subcoronal) where the urinary opening is wide and the penis is straight, non-operative management is clinically viable. The child experiences normal urinary voiding while sitting or standing and faces no future sexual dysfunction. The decision to proceed with surgery in mild cases is elective and relies on detailed discussions between pediatric urologists and parents.

Management Option	Invasiveness	Indications	Primary Advantages	Trade-offs and Limitations
Non-Surgical Observation	Non-invasive	Mild distal defects; no chordee; normal urinary stream	Zero surgical risk; no hospitalization or catheterization	Cosmetic divergence remains; potential minor stream deviation
Single-Stage Repair (TIP)	Invasive (1 operation)	Distal to middle hypospadias; mild to moderate chordee	Single operative exposure; high success rate (85-95%)	Risk of fistula (5-10%); requires catheterization for 7-10 days
Two-Stage Graft Repair	Invasive (2 operations)	Severe proximal defects; severe chordee; poor tissue plate	Optimal curvature correction; reduced stricture risk	Requires two surgeries under anaesthesia 6 months apart

8. Pre-Treatment Phase

The pre-treatment phase includes a comprehensive pediatric urological evaluation, physical assessment of tissue elasticity, and hormonal priming in selected cases. Parents receive detailed preoperative guidelines regarding dietary fasting, infection prevention, medication adjustments, and psychological preparation for home postoperative recovery care.

During the initial surgical consultation, the pediatric urologist measures glans diameter, assesses the urethral plate width, evaluates the degree of ventral chordee, and checks for testicular descent. If the glans width is less than 14 millimeters or if the penis is abnormally small (microphallus), the clinician may prescribe a course of preoperative parenteral testosterone injections or topical dihydrotestosterone gel for 4 to 8 weeks prior to surgery. Research by Hadidi et al. (2022) demonstrates that hormonal priming increases glans size and local tissue vascularity, reducing technical difficulty and lowering postoperative complication rates in severe repairs.

Preoperative fasting follows strictly enforced guidelines: no solid food or non-clear fluids for 6 hours prior to general anaesthesia, and no breast milk for 4 hours. Clear fluids (water or electrolyte solutions) are permitted up to 2 hours before the procedure to maintain hydration. Parents receive instructions regarding bathing the child with antiseptic soap the night before surgery to minimize cutaneous bacterial colonization.

9. The Procedure — Step-by-Step Clinical Detail

Hypospadias surgery involves general anaesthesia coupled with regional caudal block for pain relief, followed by surgical straightening, urethral reconstruction, and skin realignment. Surgeons construct a functional urinary tube over a temporary soft catheter, reshape the glans, and reconstruct the skin layer, typically completing the procedure in two to four hours.

Step 1: Anaesthesia and Patient Positioning

The infant is positioned supine under full general endotracheal anaesthesia. A caudal epidural block or local penile nerve block is administered by the pediatric anaesthesiologist. This regional block provides complete intraoperative and early postoperative pain relief, significantly reducing the requirement for systemic opioids.

Step 2: Assessment and Artificial Erection

A traction suture (usually 5-0 silk) is placed through the glans penis to enable delicate tissue handling. The surgeon performs an artificial erection test (Gittes test) by injecting sterile normal saline into one of the corpora cavernosa (erectile chambers) while compressing the penile base with a tourniquet. This confirms the precise angle and location of ventral chordee.

Step 3: Orthoplasty (Penile Straightening)

The penile shaft skin is degloved down to the base. Fibrous ventral bands (dartos tethering) are meticulously excised. If residual curvature persists, the surgeon performs a dorsal midline plication of the tunica albuginea (Baskin technique) to achieve complete straightening without injuring the underlying neurovascular bundle.

Step 4: Urethroplasty (Neourethra Construction)

Using microscopic magnification loupes, the surgeon constructs the neourethra. In the standard Tubularized Incised Plate (TIP) method, a vertical midline incision is made along the urethral plate. The plate is gently tubularized over a soft 6 French or 8 French silicone fenestrated catheter using continuous running 6-0 or 7-0 absorbable synthetic sutures (PDS or Vicryl). To prevent fistula formation, a well-vascularized Dartos fascia flap harvested from the dorsal skin is mobilized and sutured directly over the entire neourethral suture line.

Step 5: Glansplasty and Reconstruction

The glans wings are mobilized laterally and approximated over the neourethra using deep interrupted stitches to construct a normal conical glans tip and a slit-like meatus. Excess dorsal preputial skin is reconfigured to cover the ventral penile shaft (Byars flaps) or excised if a circumcised cosmetic appearance is desired.

Step 6: Dressing and Catheter Securing

A compressive, non-adherent silicone dressing or silastic foam wrap is applied around the penile shaft to minimize postoperative edema and hematoma formation. The urethral stent or catheter is secured to the glans suture and routed into a double-diaper system to ensure uninterrupted urinary drainage.

10. Immediate Post-Procedure Period

During the immediate 24 to 48 hours following surgery, care focuses on monitoring pain, protecting the surgical dressing, and maintaining urinary catheter drainage. Children are observed in the post-anaesthesia care unit before discharge or overnight stay, utilizing double-diapering techniques to protect catheter tubes from contamination.

Following emergence from anaesthesia, the child is transferred to the Post-Anaesthesiology Care Unit (PACU). Monitoring prioritizes vital sign stability, dressing position, and continuous capillary blood flow to the glans penis. Urine must drain freely through the catheter into the diaper or drainage bag; absence of urine output requires immediate evaluation for stent kinking or obstruction.

Pain management integrates round-the-clock non-opioid analgesics, such as oral paracetamol (acetaminophen) and ibuprofen, along with anticholinergic agents like oxybutynin to prevent painful bladder spasms triggered by catheter irritation. Most distal hypospadias repairs are managed as outpatient day surgeries, allowing discharge 2 to 4 hours post-procedure. Proximal repairs or complex reconstructions may require a 24- to 48-hour inpatient stay for intravenous fluid management and monitoring.

11. Recovery — Short and Long Term

Recovery spans six to eight weeks for primary wound healing, with catheter removal occurring between seven and fourteen days postoperatively. Long-term monitoring continues through childhood and puberty to ensure normal urinary stream, evaluate anatomical growth, and monitor for late-onset complications such as strictures or fistula formation.

Recovery Phase Timeline

• Days 1 to 3: Peak surgical swelling and mild bruising. The child should remain relatively quiet. Continuous administration of prescribed anticholinergics prevents bladder spasms. Urethral stent drains urine into the inner diaper.
• Days 7 to 14: Outpatient clinic visit for dressing removal and delicate removal of the urethral catheter or stent. The primary surgeon inspects the healing suture line and observes the initial spontaneous voiding stream.
• Weeks 2 to 4: Dissolvable skin sutures begin to break down and drop off. Mild tissue redness is normal. The child can resume light play, but must refrain from using straddle toys, tricycles, or riding equipment.
• Weeks 6 to 8: Primary surgical healing is complete. Tissues regain mechanical strength. Full participation in daycare, school, and active sports is typically restored.
• Pubertal Evaluation: Long-term follow-up at toilet training (ages 3–4) and during early puberty assesses urinary flow rates (uroflowmetry) and checks for any recurrent curvature during growth spurts.

12. Risks, Side Effects, and Complications

Surgical complications after hypospadias repair include early wound infection, bleeding, and long-term issues such as urethrocutaneous fistula (abnormal leakage tract) or urethral stricture (narrowing). While minor swelling is common, structural complications occur in approximately five to fifteen percent of cases depending on defect severity.

According to meta-analyses published in the Journal of Pediatric Urology (Snodgrass et al., 2021), complication rates strongly correlate with defect classification, ranging from 5% in distal repairs to 25% or higher in complex proximal reconstructions.

Severity Category	Complication Name	Incidence Rate	Clinical Presentation	Standard Clinical Management
Common / Mild	Penile Edema & Ecchymosis	30% – 50%	Swelling and minor bruising of shaft skin	Self-limiting; soft supportive dressing and cold compresses
Common / Mild	Bladder Spasms	15% – 25%	Intermittent pelvic pain, crying, diaper wetness around stent	Oral anticholinergic therapy (oxybutynin)
Uncommon / Moderate	Urethrocutaneous Fistula	5% – 12% (Distal) 15% – 25% (Proximal)	Urine leaking from an abnormal side hole on shaft during voiding	Surgical revision delayed at least 6 months post-initial repair
Uncommon / Moderate	Urethral Stricture / Stenosis	3% – 8%	Weak, straining, thin, or spraying urinary stream	Urethral dilation under sedation or internal urethrotomy
Uncommon / Moderate	Wound Dehiscence / Glans Breakdown	2% – 5%	Separation of glans wings or skin flap suture lines	Conservative healing followed by secondary revision if needed
Rare / Serious	Urethral Diverticulum	1% – 3%	Ballooning of ventral shaft during voiding; post-void dribbling	Surgical excision of dilated urethral segment and reconstruction

Warning signs requiring immediate medical evaluation include active bright red bleeding from the dressing, inability to pass urine for over 4 hours, fever exceeding 38.5°C (101.3°F), cloudy foul-smelling urine, or complete displacement of the urethral catheter.

13. Lifestyle and Behavioural Considerations

Postoperative management requires restricting vigorous physical activities, avoiding straddle toys or bicycles, and protecting the operative site for four to six weeks. Parents must follow strict hygiene protocols, maintain continuous hydration to support urinary flushing, and use protective diapering strategies during the early recovery phase.

Preoperative Optimisation

In infants with severe diaper rash, skin treatment with barrier creams and targeted antifungal or antibacterial ointments must take place prior to surgery to minimize local skin flora counts. Parents are encouraged to practice double-diapering techniques prior to surgery to familiarize themselves with post-surgical management.

Postoperative Protections

• Double-Diapering Technique: The child wears two diapers simultaneously. The inner diaper captures stool, while the urethral stent passes through a small hole cut in the inner diaper to drain urine directly into the outer diaper. This separates stool from the surgical site, dramatically reducing wound infection risks.
• Activity Restrictions: Rough play, jumping, straddle toys (rocking horses, tricycles, walkers), and sandbox play are strictly prohibited for 4 to 6 weeks to avoid mechanical shear forces on the healing shaft.
• Hygiene and Bathing: Sponge baths are mandated while the catheter and dressing remain in place. After catheter removal, gentle warm water soaking in a tub without harsh soaps is encouraged to aid suture dissolution.

14. How Outcomes Are Measured

Clinical success is evaluated using functional and aesthetic scoring systems, assessing urinary stream force, straightness during erection, and proper urethral opening placement. Outcomes are monitored via objective tools like the Hypospadias Objective Scoring Evaluation score and uroflowmetry studies during toilet-trained childhood follow-up visits.

Validated outcome tools widely recognized in clinical research include the Hypospadias Objective Scoring Evaluation (HOSE) and the Pediatric Penile Perception Score (PPPS). These objective systems evaluate five specific anatomical endpoints:

• Meatal location and shape (slit-like vertical meatus at glans tip).
• Urinary stream direction and force (single forward-directed stream without spraying).
• Penile straightness during erection (complete absence of residual chordee).
• Glans symmetry and conical appearance.
• Penile shaft skin distribution and scar appearance.

When the child achieves toilet training, objective functional testing utilizing uroflowmetry measures maximum urinary flow rate ($Q_{max}$) and flow curve morphology to confirm the absence of subclinical urethral strictures. Long-term registries indicate that over 85% to 90% of children undergoing primary distal repair achieve excellent functional and cosmetic results throughout childhood and adult life (EAU/ESPU Guidelines 2023).

15. Recent Advances and Current Standard of Care

Recent advances in pediatric urology include refined micro-surgical techniques, improved suture materials, synthetic tissue matrices, and enhanced regional pain management protocols. Modern surgical standard guidelines emphasize early single-stage reconstruction, delicate tissue handling under optical magnification, and standardized outcome tracking to optimize long-term clinical results.

Over the past decade, standard surgical care has shifted significantly toward routine optical magnification (using 2.5x to 4.0x surgical loupes), delicate micro-instruments, and ultra-fine absorbable monofilament sutures (PDS 6-0/7-0) that incite minimal tissue inflammation. Furthermore, widespread adoption of the dartos fascia interposition flap has cut postoperative fistula formation rates in distal repairs by more than half.

In complex secondary revisions or severe proximal repairs lacking sufficient native genital skin, pediatric urologists increasingly utilize acellular dermal matrices or tissue-engineered bio-scaffolds to promote mucosal regeneration without harvesting large oral mucosal grafts. Furthermore, modern regional anaesthesia approaches—such as ultrasound-guided pudendal nerve blocks and continuous caudal catheters—have greatly reduced postoperative pain and shortened recovery times.

16. Common Myths and Misconceptions

Myth: Hypospadias is caused by something the mother ate or did during pregnancy.
Reality: Hypospadias is a complex congenital condition caused by multifactorial genetic susceptibility and subtle endocrine variations during fetal urethral development; it is not caused by maternal behavior, minor dietary choices, or accidental physical trauma during pregnancy.

Myth: Routine circumcision should be performed at birth even if hypospadias is present.
Reality: Circumcision is strictly contraindicated in neonates with hypospadias because the preputial foreskin hood is vital tissue needed by the surgeon to reconstruct the urethral channel and close skin defects during repair.

Myth: Hypospadias repair should be delayed until the boy reaches adolescence so he can make his own decision.
Reality: Major clinical guidelines (AAP, ESPU) recommend repair between 6 and 18 months of age. Performing repair in infancy takes advantage of optimal tissue healing, avoids genital awareness, and prevents psychological trauma associated with genital surgery in older children.

Myth: Every child with hypospadias requires multiple operations.
Reality: The majority of hypospadias cases (over 70-80%) are distal or midshaft and are successfully corrected in a single surgical procedure. Multi-stage procedures are reserved specifically for severe proximal defects with deep penile curvature.

Myth: Having hypospadias repair guaranteed future infertility or erectile dysfunction.
Reality: Successful reconstructive surgery restores normal penile straightness and urethral length, allowing normal erection, ejaculation, and fertility in adulthood equivalent to unoperated peer populations.

Myth: Removing the urethral catheter postoperatively is extremely painful and requires general anaesthesia.
Reality: Stent or catheter removal is a quick, low-discomfort bedside or clinic procedure lasting only a few seconds, performed gently without requiring general anaesthesia or heavy sedation.

17. Frequently Asked Questions

What causes hypospadias to develop in an infant?

Hypospadias results from an arrest in normal fetal urethral development between the 8th and 14th weeks of pregnancy. It is driven by subtle variations in genetic signaling and androgen response. While most cases occur sporadically, familial patterns are observed in roughly 7% of families, indicating a underlying genetic component.

At what age should a child undergo hypospadias surgery?

Clinical practice guidelines recommended by the European Society for Paediatric Urology and American Academy of Pediatrics advise performing surgery between 6 and 18 months of age. Repairing the defect within this period optimizes tissue healing, reduces wound breakdown risks, and completes recovery well before toilet training and memory retention develop.

Can a child with mild hypospadias skip surgery entirely?

Yes. If the urinary opening is located near the tip (glanular), is wide, and is not accompanied by penile curvature (chordee) or urinary stream deviation, non-surgical observation is a safe clinical choice. The pediatric urologist evaluates the child to confirm normal voiding mechanics before recommending conservative management.

How long does a hypospadias repair surgery take?

A standard single-stage repair for distal hypospadias typically takes between 1.5 and 2.5 hours. More complex reconstructions for proximal defects involving curvature correction and tissue grafting may require 3 to 4 hours under general anaesthesia.

How is pain managed in infants after hypospadias surgery?

Pain management relies on a combination of long-acting regional blocks (such as a caudal epidural block given during anaesthesia) and regular oral doses of paracetamol and ibuprofen. Oral anticholinergic medications like oxybutynin are routinely prescribed to prevent pain caused by bladder spasms while the urethral stent remains in place.

Why is a double-diapering system used after surgery?

Double-diapering isolates the healing penile wound and catheter stent from fecal contamination. The inner diaper catches stool, while the urethral catheter drains urine directly through a small hole into the outer diaper. This setup keeps the surgical site clean, dry, and significantly reduces wound infection risks.

What should parents do if the catheter or stent stops draining urine?

If urine output stops completely for more than 2 to 3 hours, or if urine leaks constantly around the catheter while the bag stays empty, parents must contact the pediatric urology team immediately. This can indicate a kink or blockage in the stent that requires prompt evaluation to prevent bladder distension.

How long must a child stay off bicycles and straddle toys?

Children must avoid straddle toys, tricycles, bicycles, rocking horses, and rough physical play for 4 to 6 weeks postoperatively. This prevents direct pressure, blunt trauma, or shear stress on the newly reconstructed urethral channel and fragile tissue flaps during healing.

What is a urethrocutaneous fistula and how is it treated?

A urethrocutaneous fistula is an abnormal side tract or hole that forms between the reconstructed urethra and the penile skin, causing urine to leak from the underside of the shaft during voiding. If a fistula persists past 6 months, it is surgically closed using a delicate local repair procedure.

Will hypospadias repair affect my son’s future adult sexual function?

No. Corrective surgery straightens the penile shaft and places the urethral opening at the tip of the glans, establishing normal anatomical function. Long-term studies confirm that boys undergoing successful repair achieve normal erectile function, ejaculation, and fertility equivalent to the general population in adulthood.

Is preoperative hormone treatment necessary for all children?

No. Hormonal pre-treatment with topical or injectable testosterone is reserved for cases involving severe tissue deficiency, an unusually small glans penis (under 14 mm width), or severe proximal hypospadias. It enlarges local tissue structures and enhances blood vessel supply, improving technical conditions for surgery.

What is chordee and how is it corrected during surgery?

Chordee is a ventral curvature of the penis caused by restrictive fibrous tissue bands, tethering shaft skin, or unequal growth of the erectile bodies. During surgery, the surgeon degloves the shaft skin and releases fibrous bands. If curvature persists, dorsal plication of the erectile tissue is performed to achieve a straight penis.

When can my child return to daycare or school after surgery?

Most children can safely return to daycare or school 7 to 14 days after surgery, provided the urethral catheter has been removed, pain is controlled with oral medication, and staff can follow restrictions regarding rough play and physical activities.

### Can hypospadias return or worsen as a child grows?

The original birth defect does not recur; however, secondary complications like urethral stricture (narrowing) or tissue scarring can develop during pubertal growth spurts. Periodic clinical follow-up during key growth phases ensures that urinary flow dynamics and penile straightness remain optimal through adulthood.
