Noninvasive assessment of oxidative stress in pelvic organ prolapse: a feasibility study

Dominik Habes, Martin Štěpán, Ondrej Dvorak, Jana Marie Havigerová et autres

Pelvic organ prolapse (POP) is increasingly relevant in aging populations. Oxidative stress (OS) may weaken pelvic support structures, but previous studies relied on invasive tissue sampling, limiting longitudinal use. This study evaluated whether OS markers can be detected non-invasively in vaginal fluid …
