what is the diameter of a urethral sound
Aim: glans expansion. technique: urethral dilatation. I purchased a set of urethral sounds made from surgical quality stainless steel, with the following dimensions: 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38 F (1 F = 3 mm). I have been training for months approximately 1 hour once a week with sounds of successive dimensions and am now able to insert the biggest sound.
