Non-invasive assessment of the dynamics of change in the vascular bed in the buccal autograph during treatment of extended urethral strictures

Abstract

The male urethral stricture disease treatment despite all successful achievements and treatment options still remains one of the most actual and complex problems of modern urology. The presence of prolonged urethral strictures complicated with such factors as expressed scared deformation, infection, fistulae, previous unsuccessful urethral interventions, total urethral obliteration require the use of two- or multistage operations. In the light of recent times, the improvement methods dedicated to buccal mucosa graft adaptation assessment and autotransplant microvascularity evaluation are very relevant nowadays. In this study we made an attempt to estimate the dermatoscopy role in objective assessment of buccal mucosa graft microvascular network after two staged substitutive urethroplasty.The analysis of graft microphotos made in different time periods after urethroplasty allows us to define the main thing. In our point of view, the absence of evaluation changes after 90–120 postoperative days allows us to estimate a correct time for the second stage of urethroplasty-tubularization. stages of microvasculature evolution.Considering the statement that microvasculature evolution is the evolution of its graft, we think that the correct research direction is to study microangiogenesis stimulation methods.
