Post-Market Study to Assess iTind Safety in Comparison to UroLift

Официальное название

A Post-Market, Prospective, Randomized, Controlled, Multicenter International Study to Assess the Safety of the Temporarily Implanted Nitinol Device (iTind) Compared to the UroLift® System in Subjects With Symptomatic Benign Prostatic Hyperplasia (BPH)

Обзор

The study objective is to evaluate the efficacy and safety of the iTind device compared to UroLift.

Подробное описание

Both iTind and UroLift are minimally invasive treatment options for relieving lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH). The iTind device is a temporary, self-expanding nitinol implant that remains in place for 5 to 7 days to reshape the prostatic urethra through localized ischemic pressure and tissue remodeling. In contrast, the UroLift system involves the permanent placement of transprostatic implants that retract the enlarged lateral lobes of the prostate to widen the urethral lumen.

This study is designed to directly compare the safety and effectiveness of the iTind device versus the UroLift system in treating LUTS due to BPH.

Вмешательства
