Suture-Free Sealing of Tunical Defect with Collagen Fleece after Partial Plaque Excision in 319 Consecutive Patients with Peyronie's Disease: The Sealing Technique.

ABSTRACT

PURPOSE: We describe the sealing technique with collagen fleece in patients with advanced Peyronie's disease (PD) and provide the prospective long-term outcomes. MATERIALS AND METHODS: We performed a multicenter cohort study in patients with preserved erectile function and stable PD that precluded sexual intercourse. All patients underwent partial plaque excision with collagen fleece grafting. The applied technique is explained through a high-quality video accompanied by relevant animations. After hospital discharge, all patients were assessed at 1, 4 and 24 weeks after treatment. Subsequently, they presented for an additional long-term evaluation. RESULTS: From December 2004 to June 2015, 367 patients underwent surgery. Of these, 319 (86.9%) presented for the long-term evaluation and were included in the present study. At a median operative time of 79.8 minutes (range 50-130), total straightness of the penis was achieved in 299 cases (93.7%) and mean±SD penile length increased by 1.1±0.6 cm (p=0.017). After a median followup of 47.2 months (range 12-100), 291 patients (91.2%) presented with complete penile straightness. The penile glans sensation returned to the preoperative levels in 300 cases (94%). Only 11 cases of treatment-related grade 1 Clavien-Dindo complications were reported. Erectile function improved in 78 participants (24.5%) and remained unchanged in 191 (59.8%), whereas it was worsened in 50 (15.7%). Overall, the patient satisfaction rate was 87.8% and the partner satisfaction rate was 84.3%. CONCLUSIONS: Grafting with collagen fleece in patients with advanced PD is a safe and effective procedure that reduces operative time, provides an additional hemostatic effect and represents a cost-effective technique.
