(UPDATED 3/30/11 – take a look at the bottom of the post)
A case report showed up in my feed recently. A woman and her partner were using a glue container in her urethra and it got lodged in her urinary bladder. They couldn’t remove it, so they went to the emergency department, where it was removed. She was discharged after a few hours of observation.
I thought this would be a good opportunity to talk about urethral sounding. Urethral sounding (usually just called “sounding” in the kink community) is when a cylindrical object is inserted into the urethra. Most of the resources I found were aimed at men, but women can do this also (Note: the urethra in men and women are different lengths and shapes! Knowing anatomy is helpful here).
Sounds should be made out of stainless steel, hardened rubber, or a similar material. They should not have ANY cracks or deformities. Glass, although traditional, is a bad idea because it can break within the urethra. Sounds need to be sterilized before and after use! Lubrication should be water-based and glycerin-free (Source). Glycerin (aka glycerol) is a sugar, and thus can serve as food for bacteria. Yickes! I’ve seen at least one guide recommend using individual lube packets to prevent contamination.
Risks include urinary tract infections (UTIs), from poor sanitation or scratching the urethra. UTIs can lead to bladder infections and kidney infections if not treated. Cranberry juice or pills can be taken to help prevent UTIs, but should NOT replace proper hygiene.
Please talk with your doctor regarding sounding and your own health history if you plan to play with it.
