Group Intervention Description Lyrette Lyrette The Verathon Transurethral RF System (Lyrette® System) is indicated for the treatment of female urinary stress incontinence (SUI) due to hypermobility in women who have failed conservative treatment and who are not candidates for surgical therapy. The treatment is a 9 minute non-surgical procedure completed using local anesthesia during a single office visit. Women are discharged home with no incisions, dressings, or catheters immediately following treatment.
