Urinary Bladder01:23

Urinary Bladder

1.7K
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...

Urodynamic Studies: Uroflowmetry

862
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

Nursing Assessment of the Genitourinary System I: Health History

102
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,...

Anatomy of the Genitourinary System II: Bladder and Urethra

261
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...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Imaging Studies VI: Voiding Cystourethrography and Cystography

199
Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Summary
This summary is machine-generated.

Overactive bladder (OAB) prevalence and symptom severity significantly increase during pregnancy, particularly OAB-wet. OAB-dry prevalence decreases as pregnancy progresses, with overall symptom distress escalating.

Area of Science:

  • Urology
  • Obstetrics & Gynecology
  • Women's Health

Background:

  • Overactive bladder (OAB) is a common urinary symptom with unknown causes, impacting daily life.
  • Pregnancy presents unique physiological changes that may influence OAB development and severity.

Purpose of the Study:

  • To investigate the changes in overactive bladder (OAB) prevalence, symptom severity, and associated distress throughout pregnancy.
  • To differentiate the progression of OAB-dry and OAB-wet symptoms during gestation.

Main Methods:

  • A cohort of 659 pregnant women were assessed using the International Consultation on Incontinence Questionnaire-Overactive Bladder (ICIQ-OAB).
  • Data collection occurred across early, middle, and late trimesters of pregnancy.
  • Statistical analysis employed generalized estimating equations to track symptom evolution.

Main Results:

  • OAB occurrence odds increased significantly in the second (1.90x) and third (2.33x) trimesters compared to the first.
  • OAB-wet odds rose in the second (1.63x) and third (2.07x) trimesters, while OAB-dry odds showed a slight increase (0.80x) in the third trimester.
  • Symptom severity and patient-reported distress scores consistently increased from early to late pregnancy.

Conclusions:

  • Overactive bladder (OAB) and OAB-wet prevalence escalate as pregnancy advances.
  • Conversely, OAB-dry prevalence diminishes during pregnancy.
  • Both OAB symptom severity and the degree of distress experienced by pregnant individuals increase throughout gestation.
