I型胶原蛋白水凝胶微针用于小鼠压力性尿失禁的治疗与预防

Abstract

Stress urinary incontinence (SUI), a chronic disease with widespread effects and an overall prevalence of up to 46% in adult women, is associated with a heavy disease burden. The clinical treatment for mild to moderate SUI is conservative, such as electrical stimulation and Kegel exercises, but the therapeutic effect is unsatisfactory, so it is imperative to seek new treatment modalities. Hydrogel microneedles (MNs) have been widely used in transdermal drug delivery because of their minimally invasive and highly biocompatible characteristics. Therefore, for the first time, we combined collagen type I with MN technology for the treatment and prevention of mild to moderate SUI.
