Grafting in hypospadias is often discussed as a choice between tissues: preputial skin, buccal mucosa, local skin, extragenital tissue, free graft, or vascularized flap.

This episode argues that the real question is not which graft is available.

The real question is whether the graft can be trusted in the recipient bed where it is placed.

We discuss preputial skin, buccal mucosa, graft take, graft contraction, inlay grafts, staged grafting, graft beds, corporotomy fields, tubularization timing, and why graft choice should be documented as a response to a defined tissue problem.

The tubularized incised plate repair changed hypospadias surgery.

It respected native tissue, avoided flaps in many distal repairs, produced a more vertical meatus, and became the most familiar operation in modern hypospadiology.

But familiarity can be dangerous.

This episode asks a more precise question: when does TIP stop being plate preservation and become a forced tube?

We discuss urethral plate quality, glans configuration, distal calibration, proximal TIP, flow resistance, barrier layers, and why the operative note should document not only that TIP was performed, but why the plate deserved to be preserved.

Hypospadias timing is often reduced to a simple age window: six months, twelve months, eighteen months.

This episode argues that timing is not only a calendar decision. It is a readiness decision.

We discuss the four clocks that should guide surgical timing: anesthesia readiness, tissue readiness, phenotype readiness, and family readiness.

The episode focuses on how timing changes in distal versus proximal hypospadias, why staged repairs must be planned as a sequence, when endocrine evaluation should come before reconstruction, and why the “standard age window” should not replace expert surgical judgment.

STAG and STAC are not simply two-stage versus three-stage repairs.

They represent two different ways of sequencing wound healing in severe proximal hypospadias.

In STAG, curvature correction, urethral plate transection, ventral corporal lengthening, and graft placement occur in the first stage.

In STAC, straightening and shaft closure occur first. Grafting is delayed. Tubularization is delayed again.

This episode reframes STAG versus STAC as a question of biological timing: which wound should heal first, and which wound should not be overloaded?

We discuss ventral corporotomies, graft take, graft contracture, glans configuration, repeat artificial erection, tubularization readiness, and why operative documentation should describe the healing problem rather than only the named technique.

This episode is part of Season 4 of Pediatric Urology Academy: Hypospadias — Anatomy, Judgment, and Reconstruction.

Evidence basis: Campbell Chapter 56 describes STAG as a Bracka modification involving plate division, glans bed creation, graft quilting, compression, later tubularization, and warns that grafts placed over corporotomies may contract; it also describes STAC as delaying graft placement until after straightening and closure. Recent STAG-versus-STAC reports and reviews describe lower graft and urethroplasty complications with STAC in expert-center experience, but the evidence remains non-randomized and center-dependent. A 2026 JPU paper also evaluates three corporotomies during STAC for severe curvature, reinforcing the technical importance of repeated artificial erection and curvature verification.

Proximal hypospadias creates one of the oldest disagreements in pediatric urology: should repair be performed in one stage, or should it be staged?

This episode reframes the debate away from surgical ideology and toward biological risk.

The central question is not how many operations the child should have. The central question is how much curvature correction, urethral reconstruction, glans closure, tissue coverage, and wound healing can safely be placed into one operative event.

In this episode, we discuss a practical three-gate framework for decision-making:

Straightness.

Tissue quality.

Healing predictability.

We also examine why urethral plate transection becomes a major pivot point in proximal hypospadias surgery, why comparative studies are difficult to interpret, and why staging should be understood as risk control rather than failure.

Preoperative testosterone is widely used before hypospadias repair, but the evidence remains controversial.

This episode reframes androgen stimulation as measured medicine, not cosmetic enlargement. We discuss glans-width thresholds, penile length, urethral plate width, proximal hypospadias, androgen responsiveness, wound-healing concerns, fistula risk, and why response to testosterone may itself be clinically meaningful.

The central idea: testosterone should not be used to make the operation feel easier. It should be used only when it changes anatomy that truly matters.

Keywords: hypospadias, testosterone, androgen stimulation, glans width, proximal hypospadias, fistula, pediatric urology.

In proximal hypospadias, the defining decision often happens before urethroplasty begins: is the penis truly straight?

This episode reframes ventral curvature as the axis of reconstruction. We discuss artificial erection testing, the 30-degree threshold, skin tethering, urethral plate hinging, corporal disproportion, dorsal plication, ventral lengthening, urethral plate transection, and why preserving the plate may sometimes preserve the deformity.

The central idea: curvature correction is not preparation for hypospadias repair. It is the foundation of the repair.

Keywords: hypospadias, ventral curvature, chordee, urethral plate transection, dorsal plication, ventral lengthening, proximal hypospadias.

Distal hypospadias is often treated as the easy end of the spectrum. That assumption is unsafe.

This episode reframes distal hypospadias as a small-margin operation where failure may come from caliber, glans closure, tissue coverage, or meatal instability. We compare TIP, Mathieu, MAGPI, MEMO, and grafted TIP as different solutions to different anatomical problems.

The central idea: distal hypospadias is not simple because the meatus is distal. It becomes simple only when anatomy permits a stable, low-tension reconstruction.

Keywords: distal hypospadias, TIP repair, Snodgrass, Mathieu, MAGPI, MEMO, grafted TIP, pediatric urology.

Glans size is often treated as a cosmetic detail in hypospadias surgery. It is not.

This episode reframes the glans as the distal roof, pressure seal, and tension test of the reconstruction. We discuss glans width, closure tension, distal caliber, tissue reserve, androgen stimulation, glans dehiscence, and why a forced glansplasty can turn a technically good urethroplasty into a failure.

The central idea: the glans is not where the operation ends. It is where the repair proves whether it can heal.

Keywords: hypospadias, glans size, glansplasty, glans dehiscence, testosterone, urethral plate, pediatric urology.

The urethral plate is one of the most important structures in hypospadias surgery, but it is often described with vague words: good, narrow, flat, or scarred.

This episode reframes the urethral plate as a healing surface, not merely tissue to be preserved. We discuss width, depth, elasticity, vascular support, spongiosal deficiency, curvature relationship, grafted TIP, and when plate preservation becomes a liability.

The central idea: the urethral plate is not sacred, and it is not disposable. It is a decision surface.

Keywords: hypospadias, urethral plate, TIP repair, grafted TIP, glans size, ventral curvature, pediatric urology.
