Treatment of patients with urinary incontinence after prostatectomy using injection of autologous adipose-derived mesenchymal stem cells mixed with collagen gel

During the implementation of the project, it is planned to develop a method for the treatment of men urinary incontinence caused by prostatectomy using injection of autologous adipose-derived mesenchymal stem cells mixed with collagen. The positive outlook for the effectiveness of MSCs is due to the following:

• the ability of MSCs to stimulate tissue regeneration
• positive results of preclinical studies of the method of treatment of urinary incontinence in animals.

In study planing to include 5 patients. MSCs will be isolated from adipose tissue, cultured and then transplanted back to the periurethral area by five point injection in rhabdosphincter and submucosal space of urethra using the cystourethroscope. For injection in submucosal space MSCs (20*10^6 cells) will be mixed with collagen solution (3,5% w|w). Follow up patients monitoring will occur at 1，3，6 and 12 months after injection.

Inclusion Criteria:

• Urinary incontinence
• absence of acute inflammatory manifestations in the genitourinary system
• period after prostatectomy is at least 12 months

Exclusion Criteria:

• urethral or bladder malformations
• acute and chronic infectious diseases: HIV, viral hepatitis, tuberculosis
• mental disorders
