Impianto uretrale di gax collagene nell'incontinenza urinaria da stress: Studio ecografico a breve e lungo follow-up

Twenty-three patients who underwent urethral infiltration of gax collagen because of stress urinary incontinence were examined again at a mean follow-up of 37 months (24-50 months) in order to evaluate the correlation between the dimension, persistence of the submucous bulge and the clinical results. The data of our study showed no direct correlation between the size of the bulge at the site of the urethral implantation and the degree of continence achieved and confirmed a gradual disappearing of the bulge over a period of six months to one year (9/17 patients, 53% at six months) except for 2 patients who after two years still have a small residue. These two patients were both retreated, with overall volumes of gax collagen of 15 and 17.5 cc but regardless of this ultrasound aspect they became incontinent again after a year of temporary improvement.
