Summary
Parity (number of births) is not linked to urgency or urge incontinence in women over 40. Previous studies showing a link likely included women with stress incontinence, skewing results.
Area of Science:
- Urogynecology
- Epidemiology of lower urinary tract symptoms
Background:
- The relationship between parity and urgency or urge urinary incontinence (UUI) is debated.
- Varied findings may stem from differing study definitions.
Purpose of the Study:
- To investigate if case definition differences explain varied findings on parity and urgency/UUI.
- To analyze the association between parity and urgency/UUI using a large patient dataset.
Main Methods:
- Utilized data from 1,880 patients in the General Longitudinal Overactive Bladder Evaluation.
- Simulated case criteria reflecting diverse definitions of urgency, UUI, and parity.
- Employed logistic regression models for each simulated case-control scenario.
Main Results:
- Parity showed a significant association with urgency and UUI only when stress urinary incontinence (SUI) cases were included.
- No association between parity and UUI was found when SUI cases were excluded.
- No association between parity and urgency was found when general incontinence was excluded.
Conclusions:
- Urgency and UUI symptoms are not associated with parity in women aged 40 and older.
- Prior observed associations between parity and these conditions are likely due to the inclusion of SUI in study criteria.

The nursing assessment of the genitourinary (GU) system involves a systematic inspection and palpation to identify abnormalities in the kidneys, bladder, and surrounding structures.InspectionMouth: Inspect for signs of kidney dysfunction, such as stomatitis (inflammation of the mouth) and ammonia breath, which may occur in advanced kidney disease due to the buildup of urea, breaking down into ammonia.Skin: Check for pallor, which could indicate anemia caused by kidney disease.

01:23Urinary 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...

01:21Nursing Assessment of the Genitourinary System I: Health History
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,...
01:20Physiology of the Genitourinary System III: Urine Concentration and Dilution
The kidneys concentrate or dilute urine to maintain water and electrolyte balance. Nephrons, particularly the loop of Henle, play a crucial role in this process through the countercurrent multiplication system. This system establishes a high osmolarity in the renal medulla, which is essential for water reabsorption. In the loop of Henle’s descending limb, water is reabsorbed into the surrounding medulla due to its permeability to water. In contrast, the ascending limb actively transports...
01:25Urinary Tract Infection II: Pathophysiology
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...
01:17Urinary Tract Infection IV: Nursing Management
In managing urinary tract infections (UTIs) in nursing, a comprehensive assessment is essential. Begin by gathering subjective data, such as the patient’s complaints of dysuria (painful urination), urinary frequency, urgency, suprapubic pain, and any lower abdominal discomfort. This information can be complemented by questions regarding previous UTIs, sexual activity, and personal hygiene practices, which can provide insight into risk factors. Objective assessment should focus on signs like...
