Urethral strictures manifest as thin urinary lines and difficulty in urination. Common causes include congenital urethral strictures, traumatic urethral strictures, urethral strictures due to recurrent urinary tract infections, and medically induced urethral strictures. Regular urethral dilatation can relieve symptoms and even achieve a curative effect. Metal probe urethral dilatation is simple and convenient and costs about $2,000 or less. If the urethral stricture is more pronounced and the metal probe cannot pass, or even if there is urethral pseudo-tract formation, direct visual urethral dilatation must be performed, which is direct visual dilatation using a cystoscope, and the cost is usually around $1000-2000.
