Long-term results and patients' satisfaction after transurethral ethylene vinyl alcohol (Tegress) injections: a two-centre study.

Tegress is ethylene vinyl alcohol which is non-allergenic and permanent. The aim of the study was to evaluate efficacy, feasibility and safety of transurethral Tegress in women with urodynamic stress incontinence in a two-centre setting. Approximately 33 female patients with urodynamic stress incontinence were prospectively included in the study. Preoperatively, the patient's history, gynaecological examination and multichannel urodynamics were performed. On follow-up, the patient was asked to use a visual analogue scale to measure her contentness and underwent uroflowmetry and a cough test. Median follow up was 51 months. About 15 women considered themselves as completely continent, and 23 (69%) were either satisfied or very satisfied. Pad test was positive in 18 (54.5%) patients, and cough test was positive in 20 (60.6%). Patients' satisfaction did not correlate with objective dryness. Ethylene vinyl alcohol is a bulking agent with a success rate of approximately 45% after 51 months.
