Urethral dilators are medical instruments used to widen and stretch the urethra, which is the tube that carries urine from the bladder out of the body. They consist of a long, slender shaft with a tapered or rounded tip, and are available in various sizes and shapes to accommodate different patients and procedures. Urethral dilators are typically made from medical-grade materials such as stainless steel, plastic, or silicone, and can be either reusable or disposable. They are commonly used in urological procedures to treat conditions such as urethral strictures, which are narrowings or blockages of the urethra that can cause difficulty urinating or urinary tract infections. Urethral dilators are also used in some diagnostic procedures, such as uroflowmetry, which measures the rate and volume of urine flow. The use of urethral dilators requires specialized training and should only be performed by trained medical professionals.
