Summary
Lower urinary tract symptoms (LUTS) increase with age in both men and women. However, men aged 50 and older experience more severe voiding symptoms than women, likely due to prostate influence.
Area of Science:
- Urology
- Gerontology
- Public Health
Background:
- Lower urinary tract symptoms (LUTS) affect both sexes and are age-related.
- Prevalence and severity of LUTS may differ between men and women.
Purpose of the Study:
- To investigate sex-based differences in LUTS prevalence and severity among Japanese adults.
- To analyze the relationship between age, sex, and LUTS using the International Prostate Symptom Score (IPSS).
Main Methods:
- A cross-sectional study of 653 individuals (446 men, 207 women) aged 30-79.
- Utilized self-administered International Prostate Symptom Score (IPSS) questionnaires completed at a public urology event.
Main Results:
- IPSS and quality-of-life scores significantly increased with age in both men and women.
- Men aged 50+ reported higher total IPSS, voiding symptom scores, and quality-of-life scores compared to women.
- Symptom severity (moderate to severe) increased with age, with higher proportions in men (52-80%) than women (27-55%) across decades.
Conclusions:
- Age is a significant factor in LUTS and quality of life for both sexes.
- Men aged 50 and older exhibit more severe voiding symptoms than women.
- While age-related bladder changes affect both sexes, prostate-related bladder outlet obstruction may contribute to increased voiding symptoms in men.

01:16Urethra
The urethra is a hollowed tubular organ through which urine is expelled from the body. This structure extends from the bladder to the external opening, allowing urine to be released.
The anatomy of the urethra differs between males and females. In females, the urethra is short, measuring about 3–4 cm in length, and opens anterior to the vaginal opening. In males, the urethra is longer and passes through the penis, serving dual purposes: expelling urine and ejaculating semen. The male urethra is...

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
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...
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,...
01:30Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
01:19Urodynamic Studies: Uroflowmetry
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...
01:28Microbiota of the Urogenital Tract
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...
