What is urinary incontinence and how is it classified?

What is incontinence? If bladder control is lost and urine leakage occurs, it is called incontinence. Urinary incontinence can occur in people of all ages, and for a variety of reasons. Some, but not all, people with neurogenic bladder experience incontinence.

What is micturition syncope?

Answer From Phillip A. Low, M.D. Micturition (or post-micturition) syncope is fainting while urinating or immediately after urinating. This is likely due to a severe drop in blood pressure. Micturition syncope is most common in older men and usually when getting up at night from a deep sleep.

What nerve controls micturition?

Parasympathetic (pudendal nerve): Parasympathetic postganglionic nerve terminals release acetylcholine (ACh), which can excite various muscarinic receptors in bladder smooth muscles, leading to bladder contractions.

How do you control micturition?

To retrain your bladder, your doctor will advise you to follow a regular bathroom schedule. Try holding off for 10 minutes after the initial urge to go. Your doctor may encourage you to gradually increase the length of time between each bathroom visit. Try to avoid emptying your bladder between visits.

What causes neurogenic bladder?

Neurogenic bladder is the name given to a number of urinary conditions in people who lack bladder control due to a brain, spinal cord or nerve problem. This nerve damage can be the result of diseases such as multiple sclerosis (MS), Parkinson’s disease or diabetes.

What are the two phases of micturition?

Physiology. The micturition cycle involves two phases: bladder filling/urine storage and bladder emptying.

What are the 2 types of neurogenic bladder?

There are two types of neurogenic bladder dysfunction.
  • Overactive bladder causes you to have little or no control over your urination. It can also cause you to feel a sudden or frequent need to urinate. …
  • Underactive bladder occurs when your bladder muscles lose their ability to hold your urine.

What is the importance of micturition?

Urination or micturition removes metabolic products and toxic wastes filtered from the kidneys and is a vital function of the human body. The micturition reflex requires a complex network of signals between the nervous system and the urinary tract system.

What is micturition and how it is regulated?

The kidneys filter the urine and it is transported to the urinary bladder via the ureters where it is stored till its expulsion. The process of micturition is regulated by the nervous system and the muscles of the bladder and urethra. The urinary bladder can store around 350-400ml of urine before it expels it out.

What is the difference between overactive bladder and neurogenic bladder?

In people with neurogenic bladder, the nerves and muscles don’t work together very well. As a result, the bladder may not fill or empty correctly. With overactive bladder (OAB), muscles may be overactive and squeeze more often than normal and before the bladder is full with urine.

What causes atonic bladder?

Atonic bladder occurs due to a nerve signaling problem that may occur after a stroke, spinal injury, or tumor. The condition causes the bladder to be in one of three states: flaccid, spastic, or a mix of the two. Flaccid refers to the bladder not being able to contract, resulting in urinary overflow.

What causes hypotonic bladder?

Causes include hypotonic bladder resulting from age, neurologic conditions such as diabetes or spinal cord injury, prior surgery, drug effects (e.g., intravesical Botox), or fecal impaction.

What are the symptoms of neurogenic bladder?

These are the most common symptoms of neurogenic bladder:
  • Urinary tract infection (UTI)
  • Kidney stones.
  • Urinary incontinence (unable to control urine)
  • Small urine volume during voiding.
  • Urinary frequency and urgency.
  • Dribbling urine.
  • Loss of feeling that the bladder is full.

What is Atony bladder?

A.1 Terminology. Atonic (or acontractile) bladder is a medical condition where patients are unable to spontaneously urinate due to insufficient detrusor muscle contraction, usually due to neurologic disease or injury.
