Long-term results of the surgical treatment of penile curvature with 16-dot plication : a retrospective analysis of 86 patients / 中华泌尿外科杂志

ABSTRACT

Objective To assess the long-term surgical outcomes,patient's satisfaction and functional results of correction for patients with penile curvature by 16-dot minimal tension plication.Methods Between August 2004 and December 2010,92 patients with penile curvature underwent surgical correction of penile curvature by 16-dot minimal tension plication.Of them,86 patients (53 patients with congenital penile curvature and 33 patients with Peyronie's disease (PD)) were reached for long-term follow-up.Indications for operation included patients with 30 to 90 degrees of penile curvature,penile length greater than 10 cm and patients who had one or more symptoms,such as difficulty or inability to vaginal penetration and partner discomfort during sexual intercourse.Patients were excluded from study if they had severe penile curvature (greater than 90 degrees),hourglass deformities or large plaques.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 (PDE-5) inhibitors 2 weeks after surgery and maintained for 2 to 3 months.At follow-up,recurrence rate,complications,erectile function,patients and partner's satisfaction with the surgery were assessed.Results The mean time of follow-up was 79 months (range,35-107 months).Of 86 patients who had been reached for long-term follow up,82 patients (95.3％) and 77 partners (89.5％) reported overall satisfaction after the surgery.Complete penile straightening was achieved in 79 patients (91.8％).Slight residual curvatures were observed in 7 patients,but did not affect their sexual intercourse.Postoperative penile length shortening (median penile length loss 1.3 cm) was noted in 35 patients (40.7％),which did not affect their sexual intercourse.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 had received PDE-5 inhibitors for 2 to 3 months.There were no surgery-related complications,such as hematoma,urethral injury,or infection.Conclusion The longterm results demonstrate that correction of penile curvature using 16-dot plication is a simple and safe method to achieve cosmetic and functional satisfaction in patients with mild to moderate penile curvature.
