Abstract (original English)

Background/Objectives : Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic condition characterized by pelvic pain, urinary symptoms, and reduced quality of life, with limited effective treatment options. Regenerative approaches using adipose-derived mesenchymal stromal cells (MSCs) have shown promising preclinical results. This study aimed to evaluate the feasibility, safety, and preliminary efficacy of transurethral implantation of autologous micronized adipose tissue (MAT) in patients with refractory IC/BPS. Methods : We conducted a single-center retrospective observational pilot study including 20 patients with refractory IC/BPS treated between April and October 2024. Adipose tissue was harvested via liposuction and mechanically processed using a closed system (Matrigen device) to obtain minimally manipulated micronized adipose tissue. The product was injected transurethrally into the bladder submucosa. Patients were evaluated at baseline and at 1, 3, and 6 months using validated questionnaires (ICSI/ICPI, SF-36, MOS Sexual Function), verbal rating scale (VRS) for pain and urgency, urodynamic parameters, and cystoscopic findings. Changes over time were assessed using paired non-parametric tests. Results : At 6 months, 65% of patients met responder criteria, defined as ≥50% improvement in pain and/or urgency or a positive global response. Significant improvemen

What this study does not prove

  • • This study does not prove SVF is an approved treatment or a replacement for standard care.
  • • Without an adequate control group, treatment effects cannot be separated from other factors.
