Principles of Genital Reconstruction
This section covers reconstruction of penile, scrotal, vulvar and perineal defects after disease, injury or tissue loss. Plan around the tissue actually missing and the patient's priorities for urinary function, sexual activity, sensation, appearance and daily care. Coverage alone is not a complete functional outcome.[1][2]
The dedicated Gender-Affirming Surgery section covers those pathways. Peyronie's surgery addresses tunical deformity; the present skin and soft-tissue principles should not be used as a substitute for that assessment.
Define the defect before choosing a technique
| Domain | Questions that change the operation |
|---|---|
| Skin and soft tissue | What viable skin remains? Is the problem limited to surface coverage, or is there fibrosis, lymphedema or substantial dead space? |
| Urethra and voiding | Is there a meatal/urethral lesion, fistula or obstruction requiring separate evaluation or reconstruction? |
| Glans, corpora and neurovascular structures | Which structures are intact, exposed or injured? What can be preserved safely? |
| Scrotum and testes | Are the testes and their coverings viable? Can residual scrotal tissue provide tension-free coverage? |
| Vulva, vagina and perineum | Will closure narrow or displace the introitus, urethral opening or anus? Is deeper vaginal or pelvic reconstruction required? |
| Recipient and donor tissues | Consider previous surgery, radiation, scars, vascular supply, tissue quality and donor morbidity |
Deep pelvic defects require a plan for filling dead space and protecting organs, in addition to replacing skin. Coordinate with the relevant urologic, gynecologic, colorectal and plastic-surgery teams before an extensive resection.[1][3][2]
Choose the reconstruction that meets the need
The reconstructive ladder organizes available options; it does not require failure of every simpler operation before selecting a suitable flap.
| Option | Typical role | Main limitation |
|---|---|---|
| Primary closure or local advancement | Adequate viable tissue that closes without tension or distortion | Excessive tension can compromise healing or narrow adjacent openings |
| STSG or FTSG | Surface coverage on a vascularized bed | Requires revascularization; cannot fill substantial dead space; contracture and sensory changes remain possible |
| Local or regional flap | Provides vascularized coverage, sometimes with useful bulk | Pedicle reach, prior treatment and donor morbidity constrain choice |
| Free tissue transfer | Selected extensive, composite or otherwise unsuitable defects | Requires recipient vessels, microsurgical expertise and a postoperative monitoring plan |
Vascularity, depth and functional requirements matter alongside defect size. A large superficial genital wound may accept a graft, while a smaller but deep defect may need vascularized tissue. Exposed testes alone do not automatically require a flap if a suitable vascularized covering remains.[4][1][3]
Establish readiness and preserve viable tissue
Control infection and remove nonviable tissue before definitive reconstruction. Following destructive infection, proceed when the wound is stable and further debridement is not needed; no fixed waiting interval suits every patient. Tailor excision to the disease while preserving unaffected skin, dartos and important neurovascular structures when appropriate.[4]
For grafts, establish hemostasis and close contact with a viable recipient bed, then protect against shear, fluid collection and constriction. Dermal matrices and NPWT are selective adjuncts, not substitutes for wound preparation. Integra must not be placed on a clinically infected wound; use the exact product's instructions.[4][5]
Radiated, scarred or repeatedly operated tissues may require recruitment of healthier vascularized tissue. Coordinate donor and pedicle choices with abdominal incisions, previous flap harvest and stoma requirements. Immediate versus staged reconstruction depends on source control, margin assessment, the exposed structures and the consequences of leaving the wound open.[3]
Match the plan to the anatomy
Penile skin: preserve adequate mobility for erection and avoid a constricting closure. Assess shaft skin, glans, urethra and corpora separately. Graft thickness and donor selection involve tradeoffs; small retrospective comparisons do not prove STSG and FTSG equivalent. See Penile Skin Grafting.[4]
Scrotum: preserve viable residual tissue when possible. Grafts and regional flaps are both established options. A 2026 review of 107 reports encompassing 619 patients and 625 flaps reported low flap loss, but heterogeneous populations, limited comparative data and inconsistent functional reporting prevent a universal graft-versus-flap rule.[6] See Scrotal Reconstruction.
Vulva and perineum: preserve or restore the position and caliber of urinary, vaginal and anal openings; minimize painful scar tension and consider the patient's sexual goals. Choose among local, thigh-based, abdominal or other flaps according to the three-dimensional defect and donor tissues. No single standardized flap sequence fits every vulvovaginal resection.[2][1] See Vulvar Reconstruction.
Reconstruction after penile tumor excision
The oncologic plan comes first: establish histology, achieve appropriate negative margins and choose organ preservation when suitable. Current EAU guidance supports organ-sparing treatment for selected disease confined to the glans or prepuce with appropriate follow-up. Mohs surgery has limited penile-cancer evidence and is not routinely recommended. Glans resurfacing differs from glansectomy with neoglans reconstruction. There is no universal two-centimeter stump rule guaranteeing urinary or sexual function, and total penectomy does not obligate later phalloplasty.[7]
Discuss reconstruction within the oncologic team and preserve options for surveillance or further treatment. This section addresses defect reconstruction, not the complete cancer-management pathway.
Counseling and follow-up
Document baseline function and the outcomes the patient values. Discuss donor wounds, staged surgery, loss of sensation, painful erection or intercourse, contracture, wound problems, recurrent disease and possible revision. A favorable early appearance or graft-take percentage does not guarantee normal long-term sensation or function.[4][2]
Follow-up should assess wound and donor-site healing, urinary function, sensation, sexual comfort, contracture and recurrence, with disease-specific surveillance when indicated. Record patient-reported outcomes and clearly distinguish people, operations, graft area and time to recurrence when describing results.
