The Micturition Reflex01:26

The Micturition Reflex

3.6K
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...

Nursing Assessment of the Genitourinary System I: Health History

570
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. Gathering Patient InformationA complete health history includes the patient’s personal,...

Urinary Bladder01:23

Urinary Bladder

4.3K
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...

Disorders of the Urinary System01:20

Disorders of the Urinary System

1.9K
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...

Nightmares and Night Terrors01:18

Nightmares and Night Terrors

812
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Microbiota of the Urogenital Tract01:28

Microbiota of the Urogenital Tract

36
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...

Summary

Five distinct patterns of childhood bedwetting were identified. Male gender, developmental delay, and maternal history of bedwetting increase the risk of persistent nighttime wetting in children.

Area of Science:

  • Pediatrics
  • Developmental Psychology
  • Epidemiology

Background:

  • Childhood bedwetting (nocturnal enuresis) affects a significant number of children.
  • Understanding the longitudinal patterns and risk factors for bedwetting is crucial for effective intervention.

Purpose of the Study:

  • To identify distinct longitudinal patterns (phenotypes) of bedwetting frequency from ages 4 to 9 years.
  • To investigate associations between these bedwetting patterns and factors like developmental delay, parental history, birth weight, and gestational length.

Main Methods:

  • Utilized data from 8,769 children in the UK Avon Longitudinal Study of Parents and Children cohort.
  • Employed longitudinal latent class analysis to define bedwetting trajectories.
  • Examined associations with sex, developmental level, parental history, birth weight, and gestational length.

Main Results:

  • Identified five latent classes: normative, infrequent delayed, frequent delayed, infrequent persistent, and frequent persistent bedwetting.
  • Male gender, developmental delay (e.g., social skills), and maternal history of bedwetting were significantly associated with increased odds of persistent bedwetting.
  • Low birth weight and shorter gestation showed minimal association with bedwetting frequency.

Conclusions:

  • Described developmental trajectories of nighttime bladder control in children.
  • Identified key predictors for the persistence of bedwetting into school age.
  • Highlighted the need for enhanced understanding of risk factors to identify and support children struggling with continence.
