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.
In human anatomy, the ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. In the adult, the ureters are usually 25â30 cm (10â12 in) long and ~3â4 mm in diameter. The upper part of the ureter closest to the kidney is supplied by the renal arteries. 2  The middle part of the ureter is supplied by the common iliac arteries, direct branches from the abdominal aorta, and gonadal arteries (the testicular artery in men or ovarian artery in women).
