Urethral dilation is a procedure that refers to the expansion and propping up of the narrow urethra, hence the name urethral dilation. Urethral dilation is a treatment for urethral stricture, not a disease, so there is no urethral dilation how to treat it, which according to the description should mean urethral dilation how to do. Urethral dilation is the most common method of treating urethral stricture and requires the use of a urethral dilator to dilate the urethra. The urethral dilator is a long round rod made of metal with a curved front section and is available in different thicknesses. The patient lies flat on the treatment bed, disinfects the perineum as well as the urethral orifice, lays a sterile cavity towel, lubricates the urethral dilator with paraffin oil, and then dilates the stricture section with a thinner urethral dilator, and then uses a thicker dilator to dilate again after passing the stricture section, generally stopping at 22.
