How do you lubricate the urethra before sounding?

To lubricate the urethra before sounding, it's essential to use a sterile, water-based lubricant specifically designed for medical use. Apply a generous amount of lubricant to the sound and to the urethral opening to ensure smooth insertion and reduce discomfort. Always ensure that your hands and any instruments used are clean to minimize the risk of infection. It's also advisable to proceed slowly and listen to your body's signals during the process.
