Transvaginal ultrasonography examines the bladder base, the urethral anatomy and the relationship between these structures. This procedure particularly evaluates the striated sphincter and periutrehral structures, during micturition attention is focused on elasticity of urethral walls, deviation of urethral axis, the presence of fibrotic rings, fibrosis extending to the whole urethra and on urethral diverticuli. At che present, the literature available does not provide certain diagnostical criteria for the identification of female vaiding disorders. The high number of proposed therapeutical solutions indicate that the solution to this problem is yet to be found.
