Gender-affirming masculinising urogenital reconstruction

Multistage creation of a phallus, lengthened urethra and scrotum using metoidioplasty or flap phalloplasty, with prosthetic stages and urethral revision linked but distinct.

Typical place in practice

Individualised gender-affirming goals after multidisciplinary assessment, fertility discussion and informed consent about staged surgery and revision burden.

Alternatives and neighbouring procedures

No genital surgery, limited external-genital procedures without standing urination, metoidioplasty versus phalloplasty, or staged decisions over time.

Same procedure family, explicit technique branches

These are variations of this canonical operation. Complication modules below identify whether they apply to all branches or only to named approaches.

01 · Clitoral release and local-tissue reconstruction

Metoidioplasty with or without urethral lengthening

Creates a sensate small phallus using native erectile tissue.

02 · Microvascular tube-within-a-tube flap

Radial-forearm free-flap phalloplasty

Constructs shaft and urethra from forearm tissue with microsurgical transfer.

03 · Pedicled or free thigh/torso flap

Anterolateral-thigh or other flap phalloplasty

Uses alternative donor tissue with technique-specific bulk and urethral options.

04 · Labial flap reconstruction with implants

Scrotoplasty and testicular prostheses

Creates a scrotum in a staged or combined pathway.

05 · Delayed erectile-device implantation

Penile prosthesis and revision

Adds penetrative rigidity after sensation and tissue healing.

06 · Endoscopic or open staged urethral reconstruction

Urethral fistula or stricture revision

Treats a common junctional or neourethral complication.

High-level sequence

Coverage outline only; not a step-by-step technical guide.

  1. Define individual urinary, sexual, sensory, appearance and reproductive goals
  2. Plan donor tissue, urethral lengthening and staging
  3. Create a well-perfused phallus and tension-aware urethral continuity
  4. Complete scrotal and later prosthetic components only after appropriate healing
  5. Provide lifelong urinary, sexual, donor-site and implant follow-up

Every failure mode is its own module.

Timing and variation coverage are recorded for each module.

Open in complication index
C01
early injury

Partial or total flap loss

Arterial thrombosis, venous congestion or tissue compromise can threaten the phallus and requires time-critical recognition.

Applies to: Radial-forearm free-flap phalloplasty · Anterolateral-thigh or other flap phalloplasty
C02
multiple leak obstruction

Urethral fistula, leak or stricture

Long multi-segment urethral construction has several vulnerable joins and blood-supply transitions.

Applies to: All variants
C03
late functional

Urinary retention, spraying or inability to void standing

Patency, geometry and continence can limit the intended urinary outcome.

Applies to: All variants
C04
early infection

Wound infection, dehiscence or pelvic collection

Large composite wounds and urinary contamination can compromise healing.

Applies to: All variants
C05
multiple wound recovery

Donor-site functional, sensory or cosmetic morbidity

Flap harvest can affect limb strength, sensation, scarring and graft healing.

Applies to: Radial-forearm free-flap phalloplasty · Anterolateral-thigh or other flap phalloplasty
C06
late functional

Altered or absent erotic/tactile sensation and pain

Nerve coaptation and native-tissue preservation do not guarantee sensory outcomes.

Applies to: All variants
C07
multiple device

Testicular or penile prosthesis infection, erosion or failure

Implants in reconstructed tissue have device-specific revision risks.

Applies to: Scrotoplasty and testicular prostheses · Penile prosthesis and revision
C08
late systemic

Dissatisfaction or psychological distress

Staging, complications and outcome variability require sustained, person-centred support.

Applies to: All variants
