Первичные результаты применения стромально-васкулярной фракции аутологичной жировой ткани при стрессовом недержании мочи у мужчин

Introduction. Male stress urinary incontinence (SUI), which affects 10 % of the population, is most commonly caused by the effects of operations on the prostate gland. Despite the presence of a large number of surgical and conservative methods to treat this disease, the problem of choosing treatment tactics is still relevant. There are limited literature data on the effectiveness of using the stromal-vascular fraction (SVF) of autologous fat in the treatment of stress urinary incontinence. The aim of this study is to analyse the usage of SVF in the treatment of SUI patients. Materials and methods. A randomised study was carried out on a group of 8 patients with stress urinary incontinence of mild and moderate severity more than one year after radical prostatectomy or transurethral resection of the prostate. The patients received stromal-vascular fractions of autologous fat into the bladder sphincter area during the period November 2017 — June 2018. Results. After 4 weeks, the Pad Test and ICIQ-SF QoL assessments showed the first positive clinical results and improving quality of life. Checkpoints of 3, 6 and 12 months were selected for measuring results. Cytological analysis of the stromalvascular fraction of autologous fat revealed the expression of mesenchymal stem cell markers CD44, CD73, CD90, which may explain the method’s high efficiency. Conclusion. This work supports the hypothesis that transplantation of SVF from autologous adipose tissue is an effective and safe method for treating patients with incontinence.
