Surgical treatment of Peyronie’s disease by modified 16-dot placation in China

OBJECTIVE: To assess the long-term patient’s satisfaction and functional results of surgical correction for Peyronie’s disease (PD) patients with penile curvature by 16-dot minimal tension placation and its modification in Chinese population. PATIENTS AND METHODS: Between August 2004 and December 2008, 32 patients with PD underwent surgical correction of penile curvature by 16-dot minimal tension placation and its modification. Indications for operation included PD patients with penile curvature, adequate erectile capacity, difficulty or inability to vaginal penetration. Preoperative evaluation included International Index of Erectile Function 5 (IIEF-5) questionnaire score, pain on erection and physical examination. Patients were recommended daily low dose phosphodiesterase type 5 (PDE5) inhibitors two weeks after surgery and maintained for two months. At follow-up, patients and partner’s satisfaction and erectile function were assessed by IIEF-5 questionnaire score. RESULTS: There were no surgery-related complications, and 94% of patients and 88% of partners reported overall satisfaction after the surgery. Complete penile straightening was achieved in 27 (84%) patients. Slight residual curvatures were observed in 4 patients, which did not affect their sexual intercourse. All patients were satisfied with postoperative penile length while shortening of the penis was noted in 13 patients (40%) with median penile length loss of 1.5 cm. In addition, no de novo erectile dysfunction was observed, and sexual function was significantly improved evidenced by the IIEF-5 scores, especially in the patients who have received PDE5 inhibitors for two months after two weeks surgery. CONCLUSIONS: Correction of penile curvature using 16-dot placation and its modification is a simple and safe method to achieve cosmetic and functional satisfaction in carefully selected PD patients.
