Sounding or urethral sounding is a medical activity using probes called sounds to increase the inner diameter of the urethra and to locate obstructions in it. It is also used to stretch the urethra in order to receive piercing.

Sounding in a sexual context (see Urethral Play) involves inserting sounds and sometimes catheters into the urethra (sometimes stretching or dilating the urethra), and sometimes bladder, for the purpose of sexual pleasure, an activity generally associated with BDSM. A urethral sound may be connected to a special electrical device for use in erotic electrostimulation. The use of urethral sounding in this way can potentially be damaging to the urethra, especially when an inexperienced partner is involved.
