Full-Thickness Skin Graft (FTSG)
A full-thickness skin graft (FTSG) contains epidermis and the full dermis. It is useful when durable, pliable coverage and limited secondary contraction are priorities, provided the recipient bed can support revascularization. In GU reconstruction it complements STSG for selected penile defects and vaginal reconstruction. Available healthy donor skin, hair distribution, wound-bed quality and donor-site closure matter more than a blanket preference for one graft thickness.[1][2]
A de-epithelialized dermal graft used for Peyronie’s reconstruction is different from an epidermis-containing FTSG; the two should not be treated as interchangeable materials.
See Grafts in GU Reconstruction for selection principles and penile skin grafting for the operative workflow.
Graft Biology — FTSG vs STSG
- Primary contraction is immediate recoil after harvest and is generally greater in FTSG because it contains more dermis. Secondary contraction occurs during healing and is generally greater with thinner STSG. These are different processes; there is no universal percentage of contraction for every graft and recipient site.[1][2]
- Human contraction data are site-specific. Stekelenburg followed 38 FTSGs in 26 patients undergoing burn reconstruction. Mean retained area was 79.1% at six weeks and 91.5% at one year. The non-randomized trunk-versus-extremity comparison does not establish a universal donor ranking for penile reconstruction.[1]
- Mechanistic studies are preclinical. Rudolph’s myofibroblast study used rats; Yamaguchi’s keratinocyte study used pigs. They help explain graft healing but do not prove human functional superiority or a fixed healing timetable.[3][4]
- Full dermis imposes greater revascularization demands. Secure contact with a vascular bed and prevention of hematoma, seroma, infection and shear are essential. The donor site is usually closed primarily, limiting practical graft dimensions; larger donor defects may themselves require reconstruction.[2]
Clinical Applications in Urology
1. Adult acquired buried penis (AABP)
Healthy skin from an excised escutcheon can provide an FTSG without a separate harvest wound. Diseased, scarred or hair-bearing donor tissue still requires careful assessment; availability alone does not establish suitability.[5][6]
| Evidence | Finding | Interpretation |
|---|---|---|
| Monn 2019, 13 patients | Complete take reported in this small escutcheon-FTSG series; two wound infections and two minor outpatient revisions | Feasibility evidence, not an expected 100% success rate for every patient |
| Jeng 2026, 32 patients with concurrent LS | Complications in 56%; three graft-loss events (two partial, one complete) and four surgical failures | All three patients with graft loss had diabetes, but the small series did not establish diabetes as the dominant independent predictor; the reported association did not reach conventional statistical significance |
| Gül, first published online in 2024, assigned to a 2026 issue | Of 39 patients, 22 received grafts: nine FTSG and 13 STSG. No statistically significant difference in the reported surgical or functional outcomes | Small retrospective comparison; absence of a significant difference does not demonstrate equivalence |
| Plamadeala 2026, 204 patients across three centres | 91 received skin grafts: 35 FTSG and 56 STSG. Across the entire reconstruction cohort, 55/204 had complications and 26/204 had recurrence; median follow-up 18 months | These are overall AABP reconstruction outcomes, not FTSG-specific rates. Satisfaction was 59/68 respondents, with questionnaires completed by only one-third of the cohort |
Sources: Monn,[5] Jeng,[6] Gül,[7] and Plamadeala.[8] Treatment selection and follow-up differ substantially between series, preventing a reliable pooled graft-choice rule.
2. Pediatric buried penis and penile skin deficiency
Wu 2026 retrospectively compared 132 inner-preputial FTSG repairs with 141 modified Sugita traditional fixation repairs, not STSG repairs, in children aged 4–7 years. Skin contracture occurred in 1/132 versus 9/141, and retraction in 2/132 versus 11/141. The graft technique was adopted later and selected partly by anatomical severity; surgeon distribution also differed. Follow-up through 12 months does not establish graft behavior during puberty, and the study excluded previous penile surgery and obesity-related burial.[9]
An earlier 11-child inguinal-FTSG series reported complete take after complex penile reconstruction, with mean follow-up of 23 months. This supports feasibility in selected cases, not a universal success estimate.[10]
3. Fournier's gangrene reconstruction
After infection control and adequate debridement, both STSG and FTSG can be used for selected penile defects. A small single-centre practice report favored FTSG to limit contracture, but that preference does not establish comparative superiority. Defect size, viable coverage over the corpora, available donor tissue and the need to accommodate erection determine the choice. Larger perineal defects or exposed structures may require flaps.[11][12][32]
4. Urethral stricture disease — historical and ongoing role
Oral mucosa is the preferred graft when available. Avoid hair-bearing urethral grafts and genital skin in LS-related strictures. Do not perform single-stage tubularized free-graft urethroplasty. These current principles take precedence over older series describing skin tubes.[33]
The Brannan and Webster series document the historical development of skin-graft urethroplasty; they should not be used to recommend a single-stage free skin tube or to derive a universal donor hierarchy from small subgroups.[13][14]
Selected extragenital skin alternatives remain relevant when oral mucosa is unavailable:
- Abdominal skin: Meeks reported 21 patients with long strictures, including recurrence and intraurethral hair growth. A larger comparative cohort included only 26 abdominal-wall skin recipients among 238 patients. The absence of a significant adjusted graft-type association does not establish equivalent durability.[15][16]
- Combined grafts: Chen compared 15 combined BMG/FTSG repairs with 115 BMG repairs. The much-quoted 0% versus 24% failure finding applied to a selected subgroup with strictures ≥6 cm, not the entire cohort, and is not randomized proof that adding skin prevents recurrence.[17]
Discuss donor morbidity, hair risk and the possibility of late recurrent stricture when selecting a non-oral substitute.
5. Peyronie's disease — plaque incision and grafting
Historical dermal grafting requires removal of the epidermis. Intact epidermis-containing FTSG is not the same material and should not be described as the standard tunical patch. Grafting decisions depend on deformity, erectile function and the risk of postoperative ED; see Peyronie’s disease.[18]
Studies of buccal mucosa, tunica vaginalis, vein and collagen fleece have differing populations, definitions and follow-up. High pooled success percentages or small non-significant comparisons do not establish equivalence across materials. The Badr review included both full reports and abstracts; it does not provide high-certainty head-to-head evidence establishing a best graft.[19][20][21][22]
6. Exstrophy–epispadias complex
In a 50-patient reconstruction series, 19 received skin grafting alone and another four received grafting with tissue expansion. The reported 96% final success included subsequent reconstruction; it is not a 96% first-operation FTSG success rate. Tissue expansion and grafting are complementary options.[23]
Applications in Gynecology / Urogynecology
1. Gender-affirming vaginoplasty (transgender women)
FTSG can supplement penile-inversion vaginoplasty when local skin is insufficient. Donor hair management and the postoperative dilation plan are central to selection.
- In the 384-patient Ghent series, 85.7% received additional FTSG. This reflects that centre’s technique and population, not the proportion universally requiring a graft. Diabetes was associated with later revision surgery; that finding is distinct from early graft loss.[24]
- In Buncamper’s prospective observational study, 32 of 100 patients received additional FTSG. No significant differences were detected in the reported patient outcomes or depth loss, but treatment was not randomized and equivalence was not demonstrated.[25]
2. Revision vaginoplasty
Van der Sluis compared 32 FTSG and 21 intestinal revisions retrospectively. Successful reconstruction was reported in 26/32 and 19/21, respectively. FTSG operations were shorter, but lower overall morbidity was not established; rectal perforation was reported in 19% of FTSG and 10% of intestinal cases. Choice requires consideration of prior surgery, tissue quality, abdominal access, dilation and bowel-related tradeoffs.[26]
3. Vaginal agenesis (MRKH syndrome)
Supported vaginal dilation is first-line for most patients who are ready for treatment. Surgery is considered after informed discussion when dilation is unsuccessful or the patient prefers surgery, ideally at an experienced centre. Surgery still requires postoperative dilation.[34]
A seven-patient FTSG series reported favorable short-term depth and intercourse outcomes, but this cannot establish superiority over dilation or other operations.[27]
4. Vaginal stenosis / foreshortening
Morley and DeLancey described flank FTSG reconstruction in ten patients with postoperative or post-radiation shortening. Eight reported excellent functional results and two improved function. This is a small historical series; radiation-related tissue quality and graft support remain individual considerations.[28]
5. Vulvovaginal reconstruction after cancer
Skin grafts may cover selected superficial defects. Deeper defects, dead space and compromised recipient beds often require vascularized flap reconstruction. See the reconstructive options reviewed by Höckel and Dornhöfer.[29]
FTSG vs STSG — Comparative Summary
| Parameter | FTSG | STSG |
|---|---|---|
| Immediate recoil after harvest | Generally greater | Generally less |
| Later contraction during healing | Generally less | Generally greater; depends on thickness, bed and scarring |
| Revascularization | More demanding because of full dermis | Thinner graft can be more forgiving; neither survives an unsuitable bed reliably |
| Donor healing | Usually primary closure | Re-epithelialization from retained dermal structures |
| Hair | Depends on donor and preparation | Thin harvest does not guarantee absence of transferred follicles |
| Penile shaft coverage | Established option in selected defects | Established option in selected defects |
| Comparative genital evidence | Limited, mostly observational | Limited, mostly observational |
Donor Sites for FTSG in GU / Urogynecologic Surgery
| Donor site | Potential use | Main considerations |
|---|---|---|
| Excised escutcheon / pannus | AABP repair | Avoid an additional donor wound when suitable; assess disease and hair carefully |
| Inner prepuce | Selected pediatric repair or urethroplasty | Limited supply; avoid genital skin for LS-related urethral reconstruction |
| Inguinal region | Selected penile resurfacing | Concealed scar, but possible hair and limited closure width |
| Scrotum | Supplemental vaginoplasty graft | Hair management is necessary before incorporation into a neovagina |
| Abdomen / flank | Selected skin or vaginal reconstruction | Closure tension, donor scar and hair distribution |
| Postauricular skin | Selected substitute when usual donors are unavailable | Small available area and a separate operative field |
Sources and limitations are described in the corresponding clinical sections above; no donor is universally best.
Key Technical Considerations
Prepare the bed and graft. Remove devitalized tissue, establish hemostasis, and confirm an adequately vascularized surface. Defat the graft carefully without damaging dermis. Plan donor closure before harvesting and avoid excessive closure tension.
Prevent shear and fluid collections. Fixation, appropriate immobilization and a bolster or selected negative-pressure dressing support graft contact. Pressure and dressing duration depend on the anatomical site and device. Ludolph’s dermal-template/NPWT series used a subsequent STSG, not FTSG; it cannot be cited as direct evidence for delayed FTSG.[30]
Assess overall healing risk. Diabetes, vascular disease, smoking, nutrition, infection, prior radiation and wound mechanics all matter. Small series cannot establish a single dominant risk factor across all genital graft procedures.[6][24]
Limitations
FTSG availability is limited by healthy donor tissue and the donor-closure plan. A poorly vascularized, infected or heavily irradiated bed may require vascularized tissue rather than a thicker free graft. Hair-bearing skin is unsuitable for urethral substitution. Comparative evidence for FTSG versus STSG in genital reconstruction remains limited.[7][15][31][33]
Key Takeaways
Use FTSG when its tissue properties and available donor suit the defect. Distinguish immediate recoil from later contraction, skin coverage from de-epithelialized dermal grafting, and observational outcomes from proven comparative benefit. For urethral substitution, apply current donor and technique restrictions; for vaginal agenesis, discuss supported dilation before surgery.
