About

This study was designed to provide confirmation of efficacy of muscle derived stem cells (MDCs) for the treatment of SUI in women.

Full description

The investigators will be assessed the 12-month potential efficacy of autologous muscle derived cells as therapy for stress urinary incontinence. A total of 20 women in whom stress urinary incontinence had not improved underwent intra-sphincter injection of low doses 50×106 of autologous muscle derived cells, which will be derived from biopsies of their deltoid muscle. Assessments will be made at 1, 3, 6 and 12 months after cell injection. Changes in stress urinary incontinence severity were evaluated by pad test, diary of incontinence episodes and quality of life surveys.

Enrollment: 20 patients
