Hypospadias — When the Urethral Opening Is Not at the Tip of the Penis
Hypospadias is a congenital condition in which the external urethral meatus (the opening of the urethra) is located on the ventral (underside) surface of the penis, rather than at its normal position at the tip of the glans. It is one of the most common congenital genitourinary anomalies in males — occurring in approximately 1 in 200 to 1 in 300 male births. In hypospadias, the urethra develops incompletely during the first trimester of foetal development, failing to fuse completely along the ventral penile surface. The spectrum of severity ranges from mild (the opening is just below the normal tip position — glanular or coronal hypospadias) to severe (the opening is at the midshaft, penoscrotal junction, or perineum — proximal hypospadias).
The goal of hypospadias repair (urethroplasty) is to reconstruct a straight penis with a normally positioned urethra at the tip of the glans, allowing the boy to stand to void with a normal urinary stream and — in adult life — normal sexual function. Hypospadias surgery at KIMS is performed by Dr. Neil Narendra Trivedi in the optimal surgical window of 6 to 18 months of age, when the operative tissue is largest relative to the surgeon's instruments and testosterone stimulation (given pre-operatively in selected cases) has maximised penile size.
Classification by meatal position
| Type | Meatal position | Frequency · Surgical complexity |
|---|---|---|
| Glanular / subcoronal | Opening just below the tip or at the coronal sulcus | Most common (50–60% of cases) · Often minimal or no chordee · Single-stage MAGPI or TIP repair · Best outcomes · Often treated as day surgery |
| Midshaft (penile) | Opening on the penile shaft | 25–30% · May have chordee (ventral penile curvature) · Single-stage TIP or Snodgrass repair if adequate urethral plate · Two-stage repair if severe chordee |
| Proximal — penoscrotal, scrotal, or perineal | Opening at the penoscrotal junction, scrotum, or perineum | 15–20% · Most complex · Always has chordee · Usually requires two-stage repair · May require buccal mucosa graft for urethral reconstruction · Staged procedure — Stage 1 corrects curvature, Stage 2 reconstructs urethra 6 months later |
Associated anomalies
Conditions commonly associated with hypospadias
Chordee — ventral penile curvature from the fibrous remnant of the incompletely developed urethra (the urethral plate). Present in severe hypospadias. Must be corrected at the time of repair to allow normal sexual function. Corrected by incising and excising the chordee tissue.
Undescended testicle — present in approximately 9% of hypospadias patients. Bilateral undescended testicles with hypospadias requires karyotype and hormonal evaluation to exclude disorders of sexual development (DSD).
Inguinal hernia — from the patent processus vaginalis that frequently accompanies hypospadias in more severe cases.
Surgical correction at KIMS — urethroplasty
Optimal timing — 6 to 18 months
Surgery performed in this window benefits from the best tissue-to-instrument size ratio, the flexibility of neonatal/infant tissue, and avoids psychological impact of genital surgery on a child who is developing gender and body awareness (above age 2 to 3 years). The foreskin — which is incomplete in hypospadias (a 'dorsal hood' of foreskin is present posteriorly, but the ventral foreskin is absent) — is preserved for use as graft material in repair. Circumcision before hypospadias repair destroys valuable reconstructive tissue and should never be performed in a boy with hypospadias.
TIP (tubularised incised plate) urethroplasty — Snodgrass technique
The most common and most successful repair for distal and mid-shaft hypospadias. The urethral plate (the strip of tissue between the meatus and the glans) is incised along its midline (widening it), rolled into a tube, and covered with a dartos fascial flap and the dorsal foreskin. Produces a slit-like neo-meatus at the glans tip. Single-stage procedure with success rates above 90% for distal hypospadias.
Two-stage repair — for proximal or severe hypospadias
Stage 1: straightening of the penis (division of chordee, application of preputial skin to the ventral shaft to create a bed for urethral reconstruction). Stage 2 (6 months later): tubularisation of the laid-down tissue into a neo-urethra, with meatal advancement to the glans tip. Buccal mucosa graft (harvested from the inner cheek — similar moisture and tissue quality to urethral mucosa) may be used in place of penile skin for urethral reconstruction in complex proximal cases.
Specialist hypospadias surgeon
Hypospadias surgery should not be attempted by general paediatric surgeons without specific training in hypospadias repair techniques. Poorly performed primary repair results in complications (fistula, stricture, meatal regression) that are far more complex and difficult to correct on redo surgery than the original anomaly. At KIMS, hypospadias repair is performed by Dr. Neil Narendra Trivedi with specific training in paediatric urological reconstruction.

Frequently Asked Questions — Hypospadias
Mild distal hypospadias (glanular — the opening is only slightly below the tip) with no chordee and a normal urinary stream may cause minimal functional problems and some men elect not to have surgery. However, untreated hypospadias — particularly moderate and severe forms — causes a downward-directed urinary stream (preventing normal standing urination), penile curvature that affects sexual function, and psychological impact from the altered penile appearance. The consensus recommendation is surgical correction in infancy — not because it is an emergency, but because early repair avoids the psychological impact of surgery at an older age when body awareness and anxiety are greater.
The foreskin in hypospadias is abnormal — a 'dorsal hood' exists (the posterior part of the foreskin is present) but the ventral foreskin is absent (because the foreskin fails to close ventrally in parallel with the failure of urethral fusion). This dorsal hood of foreskin is the most valuable local tissue for urethral reconstruction — it is used as a pedicled flap or free graft to cover the reconstructed urethra in many hypospadias repair techniques. Circumcision before hypospadias repair permanently destroys this tissue. Any boy with an incomplete foreskin (dorsal hood only, no ventral foreskin) should be assessed by a paediatric urologist before any circumcision is performed, regardless of cultural or religious reasons.
The most common complications of hypospadias repair: urethrocutaneous fistula (a small hole developing between the reconstructed urethra and the skin — presenting as a secondary urinary stream or urine leaking from the shaft rather than the meatus, occurring in 5 to 15% of repairs, more common in proximal repairs and redo surgery), meatal stenosis (the neo-meatus becomes narrow, causing a thin or obstructed stream — treated by calibration or meatotomy), and urethral stricture (narrowing of the reconstructed urethra causing voiding difficulty). All complications are manageable — but prevention through careful primary repair at a specialist centre is the most important strategy.
Severe proximal hypospadias — with the urethral meatus at the penoscrotal junction or perineum — may impair fertility if semen is deposited at the perineum rather than intravaginally during intercourse. Surgical correction places the meatus at the glans tip, allowing normal intravaginal ejaculation. Fertility is also affected if the concurrent undescended testicle (present in 9% of hypospadias patients) is not treated with timely orchidopexy — bilateral undescended testicles with hypospadias carry a particularly high infertility risk. Distal and corrected mid-shaft hypospadias does not affect fertility.
