An Open Multicenter Study of Clinical Efficacy and Safety of Urolastic, an Injectable Implant for the Treatment of Stress Urinary Incontinence: One-Year Observation

摘要

The prevalence of stress urinary incontinence rises and affects up to 30% of women after 50 years of age. Midurethral slings are currently the mainstay of surgical anti-incontinence therapy. Some patients experience recurrent SUI (RSUI) which is defined as a failure of anti-incontinence surgery after a period of time or persistence of SUI after the procedure aimed at correcting it. The urethral bulking agent application decreases invasiveness of treatment and meets patients requirements. The objective of this study was to assess the safety and clinical efficacy of Urolastic injection. One hundred and five patients with SUI (including 91 patients with RSUI) were treated with Urolastic in three tertiary gynecological clinics. The efficacy of the procedure was assessed objectively at each follow-up visit by means of cough test and a standard 1-hour pad test. Objective success rate after 12 months after primary procedure in RSUI patients was found in 59.3% of patients. In 14 patients with primary SUI improvement after 1 year was found in 71.4% of patients. Although cure rates after MUS are up to 90% there is still place for less invasive treatment option like periurethral injection of bulking agents, especially in patients with previous SUI surgical management.
