Summary
Underactive bladder (UAB) may develop from chronic overactive bladder (OAB) due to factors like aging or diabetes. Early OAB treatment could potentially prevent UAB progression.
Area of Science:
- Urology
- Geriatrics
Background:
- Overactive bladder (OAB) is common, but underactive bladder (UAB) is poorly understood.
- UAB is multifactorial, sharing symptoms with other urologic conditions and potentially overlapping with OAB.
- Detrusor hyperreflexia/impaired contractility (DHIC) in the elderly combines OAB and UAB pathology.
Purpose of the Study:
- To propose a hypothesis on the progression from OAB to UAB.
- To explore the relationship between OAB, DHIC, and UAB.
- To suggest preventative strategies for UAB.
Main Methods:
- Hypothetical model based on existing urologic knowledge.
- Analysis of OAB and UAB pathophysiology.
- Consideration of contributing factors like diabetes, obstruction, aging, sarcopenia, and frailty.
Main Results:
- Chronic, refractory OAB may progress to DHIC and subsequently UAB.
- UAB and OAB might represent stages of a single disease spectrum.
- DHIC in the elderly shares features of both OAB and UAB.
Conclusions:
- A hypothesis suggests OAB can progress to UAB.
- Early intervention for OAB may prevent UAB development.
- Understanding this progression is crucial for urologic patient care.

01:26The Micturition Reflex
3.9K
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

01:23Urinary Bladder
4.6K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

01:25Urinary Tract Infection II: Pathophysiology
1.4K
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

The urinary system is responsible for eliminating waste and excess fluids from the body. However, disorders of the urinary system can arise due to various reasons like infections, stress, age, congenital abnormalities, and lifestyle.
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...

The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1.
