Interesting paper, published in the journal UROLOGY (Urology. 2012 Nov;80(5):1051-5).
The author concludes that plaque excision and skin grafting should only be recommended for Peyronie's disease patients with good erectile capacity, with a large deviation (which cannot be corrected by plication alone), for patients who do not accept any shortening of the penis and if the size of the tunica defect (penis) is < 3cm. A defect of 3 cm should not be exceeded, as the larger the defect, the greater the chance of erectile dysfunction.
This study is yet another in the literature that demonstrates the need to reduce the area of the graft in order to also reduce the chance of losing penile rigidity in the post-operative period.
