The primary goal of hypospadias repair is to achieve normal urinary function and anatomical alignment for future sexual health. Hypospadias affects approximately 1 in 200 to 1 in 300 live male births according to European Association of Urology (EAU) epidemiology data. The condition involves three main anatomical components: an abnormally located urethral meatus, ventral penile curvature (chordee), and an incomplete hooded foreskin. Reconstructive techniques mobilize local tissue, release tethering chordee tissue, and form a new urethral channel (neourethra). Early intervention during infancy leverages high tissue elasticity, minimizes psychological trauma, and ensures complete healing prior to toilet training.

Hypospadias repair is performed under general anesthesia combined with a caudal epidural or penile nerve block for perioperative pain control. The surgical team marks anatomical landmarks and places a traction suture in the glans penis. If chordee is present, the penile skin is mobilized and fibrous tissue is dissected off the ventral corporal bodies (orthoplasty) until artificial erection testing confirms a straight penis. For neourethral construction, the urethral plate is mobilized; in Tubularized Incised Plate (TIP) repair, a vertical midline incision is made along the plate, which is then tubularized over a small urethral stent using fine absorbable sutures. A vascularized subcutaneous flap (such as a dartos flap) is harvested from the dorsal foreskin and tunneled ventrally to cover the neourethra as a protective intermediate layer. Glanuloplasty is performed to close the glans wings over the newly formed meatus, and the penile skin is reconstructed or circumcised. A soft silicone urethral stent or Foley catheter is secured to drain urine during initial healing.

Evidence-based clinical benefits of hypospadias repair include restoring a forward-directed, single urinary stream from the tip of the penis, enabling standing micturition in early childhood. Reconstruction eliminates ventral penile curvature, ensuring normal erectile anatomy and function for adult sexual health. Repair corrects the aesthetic appearance of the glans and foreskin, mitigating body image concerns and anxiety during adolescent development. Studies by Snodgrass et al. (2015) demonstrate long-term functional success rates exceeding 90% in primary distal repairs when performed by experienced pediatric urologists.

Immediate recovery involves maintaining a specialized double-diapering technique or catheter drainage bag for 7 to 14 days post-surgery to protect the healing neourethra. Pain is managed using oral paracetamol, ibuprofen, and occasional bladder spasm medication such as oxybutynin. Light activity is permitted, but straddle toys, rough play, and swimming are restricted for 4 to 6 weeks. Complete epidermal healing occurs within 2 to 3 weeks, while deep tissue maturation and scar softening continue over 6 to 12 months. Long-term developmental assessments follow the child through toilet training and puberty.

Hypospadias repair treats congenital urethral anomalies classified by meatal position: distal hypospadias (glanular, coronal, or subcoronal), intermediate hypospadias (midshaft), and proximal hypospadias (penoscrotal, scrotal, or perineal). It concurrently corrects associated conditions including ventral penile curvature (chordee), meatal stenosis, foreskin dorsal hood deformity, and bifid scrotum. In complex proximal presentations, surgical protocols address severe urethral plate hypoplasia and associated penoscrotal transposition.

Preoperative evaluation includes a physical examination by a pediatric urologist to confirm meatal location, urethral plate quality, and presence of undescended testes. Blood tests are rarely required unless there is a personal or family history of bleeding disorders. If the penis or glans is exceptionally small (microphallus), a short course of preoperative parenteral testosterone or topical androgen cream may be prescribed 4 to 8 weeks prior to surgery to enlarge tissues and improve vascularity. Preoperative fasting guidelines must be strictly followed (typically clear fluids stopped 2 hours prior and solid food 6 hours prior to anesthesia). Diaper dermatitis or skin irritation in the groin area must be treated and resolved prior to the procedure date.

Surgical risks of hypospadias repair are stratified by defect severity. Common and minor risks include localized postoperative edema, minor blood staining on dressings, penile bruising, and mild bladder spasms related to urethral stent irritation. Less common complications include localized wound infection, superficial skin dehiscence, and meatal stenosis (narrowing of the new urethral opening). Serious long-term complications include urethrocutaneous fistula (an abnormal passage leaking urine from the ventral shaft), urethral stricture (narrowing of the reconstructed urethral tube), recurrent penile curvature, urethral diverticulum (ballooning of the neourethra during voiding), and complete breakdown of the repair (dehiscence). Revision surgery may be required in 5% to 10% of primary distal cases and up to 20% to 30% of complex proximal repairs.

The clinical journey for hypospadias repair begins with a comprehensive outpatient evaluation by a pediatric urologist between 3 and 6 months of age to classify the anatomical severity and plan surgical timing. Surgery is scheduled between 6 and 18 months under general anesthesia with local nerve blocks. On procedure day, repair is completed in 1.5 to 3 hours, and the patient is discharged home after recovery. A urethral stent or catheter remains in place for 7 to 14 days to drain urine and support tissue healing. Clinical follow-up occurs at 1 week, 1 month, 6 months, and annually through toilet training to evaluate urinary stream, tissue healing, and long-term penile growth.
