Penile Skin Grafting
Penile skin grafting is the cross-cutting reconstructive technique used to resurface the penile shaft when skin loss is too extensive for primary closure. It is the workhorse of adult-acquired buried penis (AABP) repair, Fournier's-gangrene reconstruction, penile lymphedema debulking, glans resurfacing after partial penectomy / glansectomy, hidradenitis-suppurativa resection, foreign-body / filler-granuloma excision, and circumcision / traumatic skin loss. Both STSG and FTSG are used, and graft take exceeds 90% in most modern series.[1][2]
For indication-specific workflows see Buried Penis Repair, Penile Reconstruction, Scrotal Reconstruction, and Glans Reconstruction. This page focuses on the graft technique itself — donor-site selection, harvest, application, bolster fixation, and outcomes.
Indications
| Indication | Notes |
|---|---|
| Adult-acquired buried penis (AABP) | Most frequent urologic indication; LS-driven in ~55% of grafted cases[2] |
| Fournier's gangrene | After radical debridement; FTSG specifically recommended on the penis to avoid contracture[3] |
| Penile / scrotal lymphedema | After radical excision of lymphedematous tissue[4] |
| Penile cancer (organ-sparing) | Glans resurfacing or distal-shaft WLE; local recurrence 0–10%[5] |
| Hidradenitis suppurativa | After wide local excision[6] |
| Foreign-body / filler granuloma | After complete granuloma excision; dermal substitute + NPWT + STSG[7] |
| Circumcision injury / trauma | Including post-circumcision buried penis[8] |
STSG vs FTSG
| Feature | STSG | FTSG |
|---|---|---|
| Thickness | 12–18 / 1000 inch (0.30–0.46 mm) | Full dermis |
| Take rate | 80–100% (mean ~92%) | ~100% in selected series |
| Contracture risk | Higher (~13–19%) | Lower |
| Hair bearing | No | Donor-dependent |
| Donor morbidity | Lower (re-epithelialization) | Higher (primary closure required) |
| Preferred when | Large defect, contaminated / compromised bed, AABP default | Smaller defect, well-vascularized bed, potency priority, Fournier's |
A comparative analysis (Gül 2026, n = 22) found no significant difference between STSG and FTSG in complications (p = 0.397), recurrence (p = 0.375), or functional outcomes (IIEF and IPSS both improved, p < 0.001).[9]
Donor Sites
- Anterolateral / medial thigh — traditional dermatome STSG donor[1][10]
- Excised escutcheon — "same-field" donor that eliminates a separate wound; specimen is laid skin-up on a back table and dermatomed (STSG) or sharp-dissected + defatted (FTSG). The Jeng 2026 series of 32 patients using escutcheon-derived FTSG for AABP + LS achieved 87% complete graft success[11][12][13]
- Pannus (Figler trapezoid technique) — pannus mobilized with superior attachments intact; STSG harvested at 18 / 1000 inch in 2-inch sections before the pannus is excised[14]
- Posterior auricular / suprapubic / abdominal — for FTSG in glans resurfacing
- Buccal mucosa — not for shaft coverage; reserved for combined urethral or meatal reconstruction
Surgical Technique
1. Penile degloving and skin excision
- Circumferential incision at the corona; deglove to Buck's fascia
- Aggressive circumferential excision of all diseased shaft skin (LS, lymphedematous, scarred, granulomatous) to bleeding healthy edges
- Limited debridement → high reburying and disease progression; Santucci staging captures this (Stage 2 = penile-skin excision + STSG; Stage 3 adds scrotal excision; Stage 4 adds escutcheonectomy; Stage 5 adds panniculectomy)[15]
- Send all excised tissue to pathology (penile cancer found in ~5% of AABP specimens)
2. Wound bed preparation
- Recipient bed must be well-vascularized Buck's fascia or dartos
- Contaminated wounds (Fournier's, HS): 1–2 weeks of wound care or NPWT for granulation before grafting[6]
- Two-stage dermal-substitute protocol: Integra® or Matriderm® + NPWT × 3 weeks → STSG; complete take and 6-month elasticity in penile lymphedema and complex defects[16][7]
3. Graft harvest
- STSG depth 12–18 / 1000 inch (0.30–0.46 mm) with electric / air-powered dermatome in 2-inch sections
- For escutcheon / pannus donor, specimen on flat back table, skin-side up, stretched taut; keep moist with saline gauze until applied
- FTSG: sharp-dissect skin off subcutaneous fat; meticulous defatting of the deep dermal surface — residual fat is the dominant cause of FTSG failure
4. Mesh vs sheet
- Unmeshed sheet preferred for penile cosmesis[6][17]
- Meshed unexpanded (1:1) acceptable; slits oriented transversely; seam placed ventrally in a zigzag fashion to prevent circumferential contracture (Black series — 100% take, satisfactory cosmesis)[17]
- Expanded mesh (≥ 1:1.5) avoided on penis — poor cosmesis
5. Graft application — on stretch
- Penis must be on stretch (simulating erection) during graft fixation; otherwise tethering and acquired curvature on tumescence[6]
- Iblher pharmacologic-stretch technique: intraoperative prostaglandin E1 to induce erection during graft tailoring → non-erect / erect ratio 50–72%; preserved IIEF-5[18]
- Graft wrapped circumferentially with ventral zigzag seam
- Secure with absorbable suture or staple
6. Bolster fixation
| Technique | Detail | Evidence |
|---|---|---|
| Traditional bolster | Petrolatum gauze → mineral-oil cotton gauze → dry gauze; sutured / stapled to penis; left undisturbed 5–7 days | Figler, Strother, Tang series[14][12] |
| Rook eggcrate-foam bolster | Spikes toward wound over silver dressing; staple-secured cylindrically; removed median 4 days | 21 pts — median 100% take through POD 14, 95% at days 15–30[19] |
| NPWT bolster | −80 to −125 mmHg circumferentially | Lee 2025 SR (16 RCTs): + 8.3% take, OR 0.44 for loss, OR 0.31 for reoperation; Cao 2022 RCT: 97.6% vs 81.7% take in irregular high-mobility areas[20][21] |
| TODGA (glans resurfacing) | Proflavine-soaked gauze + tie-over sutures × 10 days | 1 / 29 needed re-graft[22] |
| Fibrin sealant | Thin layer between graft and bed; reduces hematoma | Adjunct to any bolster |
Postoperative Management
- Foley catheter for the duration of the bolster to keep urine off the graft
- Bolster removal at 5–7 days (traditional) or 4–5 days (Rook / NPWT)[14][19]
- Ambulate early; avoid sexual activity 6–8 weeks to allow maturation
- Postoperative tadalafil 5 mg daily to pharmacologically expand the graft and prevent contracture (Iblher protocol; Post / Pre ratios 81–87%)[18]
- Pelvic-floor rehabilitation can improve deviation, sensation, and sexual-function satisfaction in patients with graft-related contracture (Tremblay 2026 protocol)[23]
Outcomes
- Graft take — STSG 80–100% (mean ~92%); FTSG ~100% in selected series; ≥ 95% in outpatient pannus-donor STSG[10][11][14]
- Length / function — Plamadeala 2026 multicenter (n = 204): mean stretched length + 3.0 cm; significant urinary + sexual function improvement; recurrence-free survival 91.5% at 12 mo, 83.7% at 24 mo[24]
- Voiding — 63.6% of voiding-dysfunction patients improve[9]
- Sexual function — IIEF 22.8 vs 14.1 preoperatively (p = 0.03)[8]
- Higher complexity → lower recurrence (p = 0.018) — supports aggressive initial repair[24]
Complications
| Complication | Rate | Notes |
|---|---|---|
| Wound infection | 26–41% | Antibiotics, local care[14][13] |
| Wound dehiscence | 16–31% | Suprapubic closure; expected in high-BMI |
| Graft contracture | Long-term concern (esp. STSG) | Curvature / tethering on erection; tadalafil + PFPT |
| Partial graft loss | 6–13% | Diabetes / CVD predict; usually conservative care |
| Complete graft loss | ~3% (FTSG series) | All in diabetic patients (Jeng 2026)[13] |
| Decreased sensation | ~15% in long-term post-circumcision-AABP follow-up[8] | |
| Reburying | 12.7% overall; hematoma is the strongest predictor[24] |
Special Considerations
Lichen sclerosus
AUA Urethral Stricture Disease Guideline (2023): genital skin grafts / flaps should be avoided for urethral lining in LS due to high failure — use oral mucosa (buccal / lingual) for urethroplasty.[25] Genital skin grafts remain appropriate for shaft skin coverage in LS (graft replaces external skin, not urethral lining).[9][13]
Staged dermal-substitute protocol
For complex defects (Fournier's, extensive lymphedema, foreign-body granuloma), Integra® / Matriderm® + NPWT × 3 wk → STSG provides excellent take and elasticity without free tissue transfer.[16][7]
When to choose a flap over a graft
- Exposed corpora cavernosa / testes / urethra → pedicled scrotal flap (bipedicled, butterfly, EPAP hemi-scrotal) or thigh-based flap
- Massive defect or radiation field → pedicled ALT / VRAM or free tissue transfer
- Bothersome STSG contracture → revision with bipedicled scrotal flap or dermal-substitute regrafting[26][5]
Glans-specific grafting
Glans resurfacing after PeIN or partial glansectomy uses STSG or FTSG over cavernosal bed; TODGA tie-over bolster is well-suited to the spherical glans surface.[22][5]
Key Technical Pearls
- All diseased skin must be excised before grafting — limited debridement → reburying / disease progression
- Penis on stretch during graft application — prevents acquired curvature on tumescence
- Ventral zigzag seam — avoids circumferential contracture rings
- Same-field donor (escutcheon / pannus) — eliminates thigh donor-site morbidity in AABP
- NPWT bolster outperforms tie-over on the high-mobility irregular penile surface
- Diabetes is the dominant FTSG-loss predictor — optimize glycemic control before grafting
- Postoperative tadalafil + PFPT are adjuncts for contracture prevention / management
