Urethral sounding is a medical procedure where a doctor puts a small, thin, curved tube-shaped tool called a 'sound' into the urethra, which is the tube that carries pee out of the body. Sounding is done to help doctors look for problems, such as blockages or narrowing of the urethra. It can also help diagnose infections. The sound will go all the way through the urethra and into the bladder. The doctor can look at the inside of the urethra with an instrument called a cystoscope. This will help them figure out what kind of treatment is needed. People can feel some discomfort when the sound goes in, but it should only be uncomfortable, not painful.
