Rigi10™ Malleable Penile Prosthesis
Also Known As
Penile plication, Nesbit corporoplasty, Yachia corporoplasty, Tunica albuginea plication, Excisional corporoplasty, Incisional corporoplasty, Penile straightening surgery
Definition
Corporoplasty is a surgical procedure that involves the repair or reconstruction of the corpora cavernosa, the paired cylindrical structures within the penis that contain erectile tissue.1 This procedure is primarily performed to correct penile curvature resulting from Peyronie’s disease or congenital conditions.2 The surgery aims to restore normal penile shape and function by modifying the tunica albuginea, the fibrous envelope surrounding the corpora cavernosa.3 There are several technical approaches to corporoplasty, including excisional techniques (Nesbit procedure), incisional methods (Yachia procedure), and plication procedures, each with specific indications and outcomes.4 The primary purpose of corporoplasty is to enable satisfactory sexual intercourse by correcting penile deformities that impair penetration while preserving erectile function.5
Clinical Context
Corporoplasty is clinically indicated for patients with stable Peyronie’s disease (typically present for at least 12 months with no active inflammation or progressive worsening) or congenital penile curvature that impedes adequate sexual penetration.1 Patient selection criteria include adequate erectile function, sufficient penile length (typically >13 cm), and curvature that significantly affects sexual function.2
The surgical approach varies based on the degree and complexity of curvature. For simple curvatures less than 60 degrees, plication procedures are often preferred, while more complex deformities may require excisional or incisional techniques.3 The procedure is typically performed under local anesthesia on an outpatient basis, with an artificial erection induced during surgery to assess the degree of curvature and confirm adequate correction.4
Postoperative outcomes are generally favorable, with studies reporting 89-95% success rates for penile straightening.5 However, patients should be counseled about potential complications, including penile shortening (reported in up to 67% of patients), palpable sutures, and rarely, erectile dysfunction or recurrent curvature.6 Long-term patient satisfaction rates range from 75-85%, with most patients able to resume normal sexual activity within 6-8 weeks after surgery.7
