Sounding

What is sounding?

Sounding is inserting a smooth rod into the urethra, for the sensation. The rod itself is called a sound: sounding is the act, the sound is the object, the same distinction as with cane and caning. Of everything in this glossary, this is one of the few practices that carries a lasting medical risk.

Why it isn’t called a dilator

Because the two things don’t do the same thing, even if they live in the same drawer.

A dilator comes in a set of increasing sizes and has one purpose: getting an opening used to more girth. A sound is a single rod that goes in to feel what there is to feel. The distinction is the same as between clamps and nipple clamps, not synonyms but a category and a subset of it, and in the shop the words get used interchangeably.

There is a third object that resembles it and belongs least of all: the catheter. It is hollow, drains urine, and stays in place thanks to a little balloon. A sound is solid, drains nothing, and comes back out.

Where the word sounding comes from

From seafaring, and that origin says exactly what the instrument once was.

Etymonline records the verb sound in this sense from the mid-fourteenth century: “fathom, probe, measure the depth of water,” with or as with a lead line. It comes from the Old French sonder, from sonde, the sounding lead itself. From the 1570s it is also used figuratively: to examine, or to try to discover what is hidden.

The whole history of the instrument sits in that. A sound was a probe for a physician, something to feel with: whether a stone was there, how far along the narrowing sat, how deep it went. Measuring, then. Not stretching and not stroking. That the scene took the word for something that precisely does not measure is a shift of the same kind you see with so many borrowed medical words.

One honest note about that source. Etymonline carries the verb but not the instrument. The name of the object is derived from the act, not the other way around.

Why people do sounding

Because it is a place nothing else ever reaches.

The urethra has no play history. Everything that happens there is by definition new, and for almost no one is that still true anywhere else. On top of that comes the feeling of being at someone’s mercy. This is the kind of act you only let happen in a doctor’s office, and moving it to the bedroom is, for many people, the actual point.

• For the person on the receiving end, the pull is the mix of an unfamiliar sensation and complete surrender; there is nothing for you to steer.
• For the person doing it, it sits in the precision. This is not an act where enthusiasm helps.
• For two people together, it is usually the topic where it first becomes clear that “being careful” is not a plan.

This weighs heavier than with any other object in this list. There is no way of doing it that makes the risk disappear, and the damage that counts is not the fright of the moment but the scar afterward.

What urology knows about it

Two numbers, and they stand apart from each other.

The first is about how something like this ends when it goes wrong. Claris Oh, Darcy Noll, Athul John, and Matthew Hong went through twenty years of admissions for Asian Journal of Andrology at the hospitals of Southern Adelaide and found 27 people who had put something into the urethra or bladder themselves. Median age 44, 23 men and 4 women. Twenty cases could be resolved through the urethra with a scope; three people needed surgery with an open incision in the bladder, and in one the urethra was opened from the outside. Four people came back after discharge. The number of admissions of this kind rose significantly over those twenty years.

The second number is about what is left afterward. Aćimović and colleagues looked in Acta Clinica Croatica at 146 patients who had a urethra repaired between 2009 and 2019. The main cause of those narrowings was, across all age groups, the insertion of a catheter: 48.6 percent. Their own conclusion is that careful manipulation of the urethra is the most important prevention.

Read the two side by side and the message is unpleasantly clear. Nearly half of the permanent narrowings came about because, in a hospital, by trained people, with sterile equipment, something was put into the urethra. The basic rule that you only use sterile equipment made for the purpose is a floor, then, not a guarantee.

What I make of it

I am Victor: gigolo, trained as a psychotherapist, more than twenty-five years in this world. Sounding is something I don’t do, and that is not prudishness but a limit that has to do with my training.

In conversations the word almost always comes up by way of a clip. Someone has seen something, found it exciting, and the question that follows is whether it “can be done safely.” That answer does not exist in the form the question is asked. There is no setting at which this becomes harmless, only a difference between careful and reckless.

And what I find most telling in the literature: people put off getting help after accidents like this because they do not want to say how it happened. That delay does more damage than the object.

What you can do yourself

• Use only a polished sound of medical stainless steel, bought as such, and never something that happens to look like one.
• Sterilize before and after, and use plenty of sterile lubricant. What goes into the urethra enters an area where normally nothing goes in.
• Never push through resistance. Pushing through is exactly the mechanism by which the urethra tears, and the scar from that is the narrowing that has to be repaired later.
• Stop at blood, and see a doctor if blood does not clear within a few trips to the toilet, if there is a fever, or if you can no longer urinate.
• At the emergency room, just say what happened. They have seen it more often than you would think, and delay makes it worse.
• Do not do this after drinking. There is no act in this list where fine motor control matters this directly.

More reading on sounding

On this site, dilator covers the difference with the stretching relative. Medical play gives the frame around it, including what the Wet BIG, the Dutch law on healthcare professions, says about it.

Beyond that, the overview by Oh and colleagues is freely readable and the most level-headed piece on how such cases are resolved in a hospital.

Where this fits on this site

Sounding is not part of what I offer, and that will not change. The atmosphere around it can be: being examined, waiting, not deciding for yourself when it is over. What we settle about that beforehand, you can read on the BDSM date.

Provides the entry sound (v.2): “fathom, probe, measure the depth of water” with or as with a lead line, recorded from the mid-fourteenth century and implied in sounding, borrowed from the Old French sonder at sonde “sounding lead,” with a possible kinship to the Old English sund “water, sea,” and the figurative use from the 1570s: “examine, discover or attempt to discover that which is concealed.” Negative finding: the dictionary carries the verb but not the surgical instrument.
