Urethral sounding is the practice of inserting objects (typically made from metal or silicone) into theurethra for sexual gratification.[1] Medical probes calledsounds are often used, giving the name.
It resemblesurethral dilation, a urological procedure that uses urethral sounds to enlarge the inside diameter of the urethra and locate obstructions in the urethra, or as a treatment forurethral strictures, but is not carried out for medical reasons, nor typically with the same level of safety and hygienic precautions.[2][3]
Urethral sounding can be considered asedge play because of its risks.
The insertion of foreign bodies into the urethra can present serious medical problems. If not conducted carefully, sounding carries a risk of irritation, tearing of the urethra, orurinary tract infection.[4][5] Infections may become serious if they progress to the bladder or kidneys.[6]
Urethral play can involve the introduction of either soft or rigid items into themeatus of the penis (as well as farther in) or vulva.[7] Other toys and items, such ascatheters, may be introduced deeper; in some cases even into the bladder. Some items may even be allowed to curl several times or expand within the bladder. This action may be directly or indirectly associated with stimulation of the prostate gland and some types of bladder control.[citation needed] In women urethral sounding can lead to clitoral stimulation.[8]
