ABSTRACT
Recent advances in the treatment of urethral strictures are associated with regenerative medicine and tissue engineering. Urethral reconstruction in some cases is a difficult task for urologists due to the insufficient amount of autologous tissue and relapses, which encourages clinicians to search for alternatives. The purpose of this work is to review the latest achievements in the use of regenerative technologies, biomaterials and cell therapy in urethroplasty. The second part of the literature review presents the prospects of using the stromal vascular fraction (SVF) of autologous adipose tissue during reconstructive operations on the urethra, especially considering the availability of these cells through lipoaspiration. Tissue engineering technologies are reflected, which offer their own solutions to problems and limitations of their use. The article also provides examples of experimental studies in which cell-free and cellular biomaterials were used for urethral reconstruction. We believe that the approach of using SVF and biomatrix can become a potentially safe and effective method of therapy associated with the acceleration of regeneration processes, and can be of great benefit to patients with urethral diseases in the future.
