Urinary Bladder

Urinary Bladder

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...

The Micturition Reflex

The Micturition Reflex

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...

Ureters

Ureters

The ureters are retroperitoneal tubes located on either side of the vertebral column. They are responsible for transporting urine from each kidney to the urinary bladder. These tubes have thick walls and are approximately 25-30 cm long. Their diameter is around 10 mm at the renal pelvis, gradually narrowing to 1 mm as the ureter obliquely enters the posterior bladder wall through the ureteric orifices. The shape of these orifices is slit-like, which helps to prevent urine backflow toward the...

Disorders of the Urinary System

Disorders of the Urinary System

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...

Area of Science:

Biomedical Engineering
Urology
Wearable Technology

Background:

Urinary incontinence (UI) significantly impacts adult quality of life (QoL).
Noninvasive treatments are the primary approach for UI management.
Predicting bladder capacity can help prevent UI episodes.

Purpose of the Study:

To evaluate the efficacy of the TENA SmartCare Bladder Sensor in detecting bladder fullness in adults.
To assess the device's performance, safety, usability, and impact on QoL in real-world conditions.
To determine if the bladder detection rate exceeds 85%.

Main Methods:

30 adults with UI tested the wearable bladder sensor at home for one week.
Device performance, safety, usability, and user satisfaction were assessed.
Bladder detection and notification rates were analyzed using sensor data and participant diaries.

Main Results:

The median bladder detection rate was 89.8%, exceeding the 85% threshold (p < 0.05).
The device demonstrated a positive effect, with 67% of subjects reporting reduced leakages.
Participants reported improvements in UI symptoms and overall QoL.

Conclusions:

The Bladder Sensor effectively detects bladder fullness in adults under real-life conditions.
The device shows potential for preventing UI episodes and improving user well-being.
Further investigation into long-term benefits for continence care is warranted.
