Anatomical Context
Peyronie's disease produces penile curvature through asymmetric restriction of the tunica albuginea. The fibrous plaque — an inelastic scar within the tunica — fails to expand during erection on the affected side, while the contralateral tunica expands normally. The resulting differential creates a mechanical lever effect: the non-expanding (plaque) side becomes the concave surface, and the freely expanding contralateral tunica becomes the convex surface. The curvature axis points toward the plaque. In dorsal plaques — the most common location — this produces the characteristic dorsal curvature of Peyronie's disease; lateral plaques produce lateral deviation; ventral plaques cause ventral curvature.
Plication surgery corrects the curvature by shortening the convex (longer) side of the tunica albuginea to match the restricted concave (plaque) side, eliminating the differential expansion that produces the deformity. Sutures are placed into the outer longitudinal layer of the tunica albuginea on the convex surface, gathering and securing a fold of tunica that permanently shortens that surface. The technique does not address the plaque directly — it works around it by equalising the mechanical imbalance.
The neurovascular bundle on the dorsal penile surface must be carefully identified and protected during placement of dorsal plication sutures. The bundle runs in a defined fascial plane immediately superficial to the tunica albuginea at the dorsal midline; dissection for dorsal plication requires lateral displacement of the bundle to access the tunica surface safely. On the lateral and ventral surfaces, the neurovascular structures are less at risk, and plication sutures in these locations carry a lower neurovascular complication profile.
What the Procedure Involves
The procedure begins with circumferential penile degloving: the penile skin is retracted proximally via a circumcoronal or penoscrotal incision, exposing the full length of the tunica albuginea beneath Buck's fascia. An artificial erection is then induced by injecting normal saline directly into one corpus cavernosum via a butterfly needle, producing a functional erection that fully demonstrates the curvature angle, axis, and any secondary deformities. The surgeon identifies the convex surface — the side to be shortened — and the precise location and arc of curvature to be corrected.
Plication sutures of permanent (Ethibond, Prolene) or slowly absorbable (polydioxanone) material are placed at the point of maximum convexity on the tunica albuginea. Multiple sutures are typically placed in a transverse mattress or figure-of-eight configuration, each gathering a small fold of tunica. As sutures are tied sequentially, the convex surface shortens progressively. A repeat artificial erection is performed after each set of sutures to assess the correction achieved and guide placement of additional sutures as needed. The target endpoint is a straight or near-straight erection; slight residual curvature of less than 10 to 15 degrees is acceptable. The degloving skin is re-advanced and secured at the circumcoronal position with absorbable sutures.
Candidacy Criteria
Plication is indicated for stable Peyronie's disease — defined as no progression in curvature or symptom severity for at least 3 to 6 consecutive months — with curvature between approximately 30 and 90 degrees, preserved or pharmacologically assisted erectile function, and adequate penile length to accommodate the shortening inherent to the technique. Candidates should have failed or declined conservative management (collagenase injections, oral pentoxifylline, vacuum erection device therapy) or have curvature severity that makes non-surgical management unlikely to be sufficient. Adequate erectile function — either spontaneous or reliably assisted with PDE5 inhibitors — is essential, as plication provides a structural correction only and does not address haemodynamic erectile insufficiency.
Contraindications include severe curvature exceeding 90 degrees (where plication would produce unacceptable further shortening without achieving adequate straightening), significant hourglass or hinge deformity requiring tunica reconstruction rather than shortening, inadequate penile length precluding further shortening, and concurrent severe erectile dysfunction that is not adequately managed with PDE5 inhibitors (these men should be evaluated for concurrent IPP implantation). Active disease progression within the prior 3 to 6 months is a contraindication to elective surgical correction.
Recovery Timeline
Penile bruising and ecchymosis from the degloving procedure peak at 24 to 48 hours and resolve substantially within 2 weeks. Penile oedema affecting the distal shaft and glans may persist for 3 to 4 weeks. Return to sedentary work is generally possible at 7 to 10 days. Strenuous physical activity is restricted for 4 weeks. Spontaneous or induced erections during the healing period apply tension to the plication suture lines; low-dose daily PDE5 inhibitor therapy (penile rehabilitation protocol) initiated at 4 to 6 weeks is used to support erectile tissue oxygenation rather than to produce erections during the early healing window.
Sexual activity — including intercourse — is cleared at the 6 to 8-week post-operative visit following surgeon assessment of healing and erectile quality. Partners should be advised that the post-operative penile length will be 0.5 to 2 cm shorter than the pre-operative erect length; this is not a complication but an expected and permanent consequence of the plication technique. Final assessment of curvature correction and penile length is performed at 3 months when all oedema has resolved and suture remodelling is complete.
Risks and Complication Profile
Residual or recurrent curvature is the most common functional outcome concern, reported in 10 to 20% of cases. Some residual curvature of less than 20 degrees is generally well tolerated and does not impair intercourse in most patients. Penile shortening — of 0.5 to 2 cm on the convex (shortened) side — is an inherent and unavoidable consequence of the procedure and should be discussed explicitly before surgery. Suture knot palpability at the plication site is reported by some patients, particularly with permanent suture materials, and is usually a sensory rather than functional concern. Discomfort at the suture site during erection is uncommon but reported.
Post-operative erectile dysfunction — defined as a deterioration in erectile function relative to pre-operative baseline — occurs in fewer than 5% of appropriately selected plication patients. This low rate reflects the avoidance of neurovascular bundle manipulation that is required in grafting procedures for dorsal plaque access. Altered glans sensation following penile degloving is generally transient, resolving within 3 to 6 months in most cases. Wound complications including dehiscence and infection are uncommon.
Cost Considerations
At $8,000 to $15,000, plication is the least expensive of the Peyronie's surgical correction options. The cost advantage over grafting procedures reflects the simpler and shorter operative technique and the absence of graft material cost. No implant, dermal matrix, or pericardial patch is required. Surgeon and facility fees are the primary cost components, with variation driven by geographic market pricing and operative complexity.
Insurance coverage for Peyronie's disease surgical correction is possible when functional impairment is adequately documented — specifically, that curvature prevents comfortable intercourse and has not responded to conservative management. ICD-10 coding for Peyronie's disease and pre-authorisation through the surgeon's billing team are the appropriate pathway for coverage determination. Patients should not assume the procedure is non-covered without a specific determination from their insurer.
Selecting a Qualified Surgeon
Plication for Peyronie's disease requires fluency with penile degloving technique, artificial erection assessment, and intraoperative curvature correction judgement. The critical skill is the calibration of suture placement — selecting the correct location, pattern, and tension to achieve the desired correction without overcorrecting into contralateral curvature or under-correcting with residual deformity. This calibration improves substantially with operative volume.
Surgeons should hold ABU board certification and active SMSNA membership. An andrology fellowship with specific exposure to Peyronie's surgical correction — including both plication and grafting techniques — is the relevant training indicator. Patients should ask whether the surgeon performs both plication and grafting and can objectively recommend the appropriate technique for their specific anatomy, rather than defaulting to a single approach for all patients.
