Urinary Bladder01:23

Urinary Bladder

2.4K
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 Reflex01:26

The Micturition Reflex

1.9K
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...

Urodynamic Studies: Uroflowmetry

1.8K
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...

Anatomy of the Genitourinary System II: Bladder and Urethra

694
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...

Nursing Assessment of the Genitourinary System I: Health History

243
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,...

Nursing Assessment of the Genitourinary System II: Inspection and Palpation

514
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. Look for...

Summary

Overactive bladder (OAB) in men often co-occurs with benign prostatic hyperplasia. Patients need to be informed about potential OAB persistence or onset after prostate surgery, as predictors of failure are unclear.

Area of Science:

  • Urology
  • Men's Health
  • Geriatrics

Background:

  • Male lower urinary tract symptoms (LUTS), particularly overactive bladder (OAB), are common urological complaints with significant functional impact.
  • OAB prevalence increases with age, often alongside benign prostatic hyperplasia (BPH).

Purpose of the Study:

  • To synthesize current knowledge on non-neurogenic overactive bladder (OAB) in male patients.
  • To explore the relationship between OAB and BPH in men.

Main Methods:

  • Systematic literature review conducted in June 2020.
  • Databases searched include Pubmed, Embase, and Google Scholar.

Main Results:

  • OAB and BPH prevalence rise with age; their causal link is complex.
  • Post-prostate surgery, OAB can persist or develop (de novo detrusor overactivity up to 77%), with higher risks after radiotherapy.
  • Predictors for surgical failure and second-line OAB treatments post-surgery require further definition.

Conclusions:

  • Male OAB is frequently associated with prostatic bladder outlet obstruction.
  • Informing patients about potential OAB persistence or occurrence post-surgery is crucial, given undefined failure predictors.
