Author & Medical Reviewer: Dr. Dang Phuoc Dat (Specialist Level I) – Urology, Andrology & Reconstructive Surgery, Family Hospital Da Nang | Updated: October 22, 2026
Significant downward, upward, or lateral curvature of the erect penis can cause painful penetration, partner discomfort, severe psychological self-consciousness, and an increased risk of penile fracture during intercourse. Modern penile curvature Peyronie surgery Da Nang restores a straight, functional axis in over 95% of patients through a 45-to-60-minute microsurgical procedure that preserves erectile rigidity and glans sensation.
Quick Clinical Summary: Penile curvature arises from two distinct etiologies: Congenital Penile Curvature (CPC) caused by asymmetrical development of the tunica albuginea in young men, and Peyronie’s Disease caused by acquired fibrous plaques in men over 40. Surgical straightening is indicated when curvature is $\ge 30^\circ$ and impairs intercourse. At Family Hospital Da Nang, Dr. Dang Phuoc Dat performs nerve-sparing 16-Dot Lue Tunical Plication and Yachia Corporoplasty with intraoperative artificial erection testing.
1. Congenital>1. Congenital Curvature vs. Peyronie’s Disease: When Is Surgery Indicated?
wp-block-paragraph">A minor deviation of $5^\circ–15^\circ$ during erection is physiologically normal and requires no intervention. When curvature exceeds functional limits, clinical evaluation differentiates between:- Congenital Penile Curvature (CPC): Becomes apparent during puberty due to disproportionate elasticity of one aspect of the tunica albuginea (most commonly ventral downward or left lateral curvature). Erectile tissue and vascular flow are 100% healthy, with no calcified plaques.
- Peyronie’s Disease (Acquired Curvature): Typically affects men aged 40–70 following repetitive microvascular trauma to the tunica albuginea, forming a fibrotic, inelastic plaque that pulls the erect shaft toward the plaque (most commonly dorsal upward curvature).
EAU Surgical Indications for Penile Straightening:
- Erect shaft curvature $\ge 30^\circ$ (especially ventral or lateral angulation).
- Difficulty with vaginal penetration, dyspareunia for either partner, or high mechanical risk of penile fracture.
- For Peyronie’s disease: Transition into the stable chronic phase (pain-free erections and stable angle for at least 3–6 months; total disease duration $> 12$ months).

p-block-table">| Surgical Technique | Operative Principle | Key Clinical Advantages | Optimal Indication |
|---|---|---|---|
| 16-Dot Lue Tunical Plication | Places calibrated non-absorbable sutures on the convex (longer) side to fold the tunica without cutting into the corpora cavernosa | Least invasive, preserves 100% erectile rigidity, 45-minute operative time, minimal risk | Congenital curvature or stable Peyronie’s disease with $30^\circ – 60^\circ$ angle and adequate shaft length |
| Modified Yachia Corporoplasty (Heineke-Mikulicz) | Makes small longitudinal incisions on the convex tunica and closes them transversely | Extremely durable straightening, buried suture knots, no tissue excision required | Moderate-to-severe congenital curvature ($45^\circ – 75^\circ$) |
| Plaque Incision/Excision & Grafting | Incises the concave Peyronie plaque and covers the defect with a biological graft | Lengthens the shortened concave side without shaft shortening | Severe Peyronie’s curvature ($> 60^\circ – 70^\circ$) or hourglass deformity with strong baseline erectile function |

awkwardness in the clinic while obtaining an exact goniometric measurement of the curvature angle, Dr. Dang Phuoc Dat instructs patients on the Kelami Standardized 3-Angle Home Photography Method prior to their consultation at Family Hospital Da Nang:- How to Take Kelami Assessment Photos at Home: During a full natural erection in privacy, take three smartphone photos: (1) Top-down view (assessing left/right lateral deviation), (2) Side profile view (assessing dorsal/ventral angulation), and (3) Frontal craniocaudal view.
- Nerve-Sparing Surgical Protocol:
- Painless Spinal or Twilight Anesthesia: Ensures complete comfort throughout the 45–60 minute procedure.
- Cosmetic Subcoronal Circumcising Incision & Degloving: Conceals the external incision within a natural circumcision line while exposing Buck’s fascia.
- Intraoperative Gittes Artificial Erection Test: Sterile saline is infused into the corpora cavernosa on the operating table to induce a 100% rigid erection, allowing millimeter-by-millimeter suture tensioning until the shaft is completely straight while safeguarding the Dorsal Neurovascular Bundle.

- Never attempt to manually bend or ‘snap’ an erect curved penis straight at home: Forcible bending ruptures the tunica albuginea (producing an audible ‘pop’, acute hematoma, and ‘eggplant deformity’)—a surgical emergency known as Penile Fracture requiring immediate operative repair within 24 hours.
