"Voiding in the toilet" is the medical term for urination, meaning the act of emptying your bladder by passing urine into a toilet, a common bodily function but also a key concept in healthcare for discussing bladder control, frequency, and issues like retention or incontinence. Doctors use "voiding" to assess how well someone empties their bladder, sometimes using techniques like double voiding (urinating, waiting, and trying again) to ensure complete emptying, or timed voiding (going to the toilet on a schedule) to manage overactive bladder.
Bladder emptying refers to when a person has the urge to urinate and completely voids their bladder. Double voiding describes spending extra time on the toilet to try to empty the bladder completely. Urinary frequency can mean that a person wakes up numerous times a night wanting to go to the restroom.
It is the urinary system's form of excretion. It is also known medically as micturition, voiding, uresis, or, rarely, emiction, and known colloquially by various names including peeing, weeing, pissing, and euphemistically number one.
We do use the term void when we mean to urinate or empty the bladder.
voider, to empty] 1. To evacuate the bowels or bladder. 2. An empty space, e.g., one seen in radiographical evaluation of arteries or veins.
Normal Voiding Frequency
Normal frequency (how many times you urinate) during waking hours for adults is 5-8 times (around every 3-4 hours).
The sensation of fullness when the bladder fills with urine triggers off a response, which alerts that it needs to be emptied. For this to happen, both sphincters need to relax and open while the bladder muscle contracts and expels the urine out of the body via the urethra.
Void: To urinate. The term void is also sometimes used to indicate the elimination of solid waste. (defecation).
Less than 100 mL PVR is considered normal. Up to 200 mL PVR may be acceptable. Over 200 mL PVR indicates inadequate emptying. Over 300 mL is suggestive of urinary retention.
Normally, bladder filling stimulates stretch receptors in the bladder wall to send impulses via spinal nerves S2 to S4 to the spinal cord, then to the sensory cortex, where the need to void is perceived. A threshold volume, which differs from person to person, triggers awareness of the need to void.
Female voiding dysfunction (FVD) is a common multifactorial condition characterized by abnormally slow or incomplete voiding of urine from the bladder. Treatment is highly individualized, with a range of options based on severity, from behavioral to medical and surgical.
The bladder never empties completely so some residue is normal. You may find it difficult to start to pass water and even when you have started, the flow is weak and slow. You might find you dribble after you have finished passing water. Perhaps you dribble urine all the time, even without noticing.
The "21-second pee rule" comes from a scientific discovery that most mammals over about 3 kg (like dogs, cows, elephants) empty their bladders in roughly 21 seconds, regardless of their size, due to physics involving urethra length and gravity. For humans, this serves as a loose benchmark: urinating significantly faster (e.g., under 10 seconds) or slower (over 30 seconds) might signal holding it too long or an overactive bladder, though it's not an exact diagnosis.
See a health care professional if you have symptoms of a bladder problem, such as trouble urinating, a loss of bladder control, waking to use the bathroom, pelvic pain, or leaking urine.
It's called post-void dribbling. And guess what? It's perfectly normal, says John Stoffel, M.D., a urologist at Michigan Medicine. “Some people have more urine dribble after voiding than others, enough so that it can soak through their pants,” he explained.
But experts say there is a certain amount of time it should take to empty your bladder. From house cats to elephants, most mammals take about 20 seconds to urinate. That goes for humans as well.
Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder. The urine is stored in the bladder until it leaves the body through the urethra.
Daytime wetting in children is commonly caused by holding urine too long, constipation, or bladder systems that don't work together smoothly. Health problems can sometimes cause daytime wetting, too, such as bladder or kidney infections (UTIs), structural problems in the urinary tract, or nerve problems.
Techniques for Complete Bladder Emptying
What is double voiding? Double voiding refers to spending extra time on the toilet to try to empty your bladder completely. Many women rush to get off the toilet and leave urine inside the bladder.
The urethra is responsible for releasing the urine stored in the bladder to the outside of the body (voiding or emptying the bladder, also called urination). In voiding dysfunction, the normal course of emptying of the bladder is compromised.
A: Most adults can safely hold their pee for about 3 to 5 hours, but it's best not to wait that long. Holding it too often can irritate your bladder and increase your risk of infection. The average bladder holds 400–600 mL of urine. “Go” when you first feel the urge, especially on long trips.
