Hypothesis / aims of study
Surgical treatment of Peyronie's disease is resorted to in copulatory dysfunction. Shortening (plication) correction methods have a
number of disadvantages (first of all, the loss of the length of the penis). Despite the great complexity and risks, lengthening
techniques are the choice of the surgeon and the patient. The main aspects determining the choice of a graft are elasticity,
extensibility, strength, and hypoallergenic. The high risk of erectile dysfunction in corporoplasty with the use of transplants, reaches
60%. One of the promising methods is the use of multipatent mesenchymal stem cells of the stromal vascular fraction (SVF) of
autologous adipose tissue. The mechanism of action is due to the presence of pericytes and endotheliocytes in SVF that contribute
to neoangiogenesis, which can reduce the risk of erectile dysfunction.
Study design, materials and methods
Pericardial allograft (Alloplant®) was used as a graft for corporoplasty. A preliminary assessment of the physical properties of the
graft (strength, extensibility) were studied. The extensibility was approximately equal, both in the longitudinal and transverse
directions. We observed the elongation of the centimeter section without loss of strength to 2 cm, the tensile strength was 2.6
kgf/cm2. Incision and grafting with a pericardial allograft was performed on 28 patients with Peyronie's disease, without erectile
disorders. In addition, the cavernous tissue and the tunica albuginea of corpus cavernosum of seven patients were injected with
SVF. The transplant was covered with SVF. The average age of patients was 53±12.3 years. Patients were examined according to
Clinical recommendations: questionnaire on the ICEF-5 scale, PDQ, pharmacodopplerography of the penis with photofixation of the
penis in 3 prespectives, measurement of deviation using a screen protractor. The average angle of deviation of the penis was 87.5°
(55-120°). Repeated examination was carried out 3, 6 and 12 months after the operation.
