What is the primary role of the bladder in the urinary system?

To store urine as a low-pressure reservoir.

Which embryonic structure divides the cloaca into the urogenital sinus and anorectal canal?

Urorectal septum.

What type of muscle composes the detrusor muscle of the bladder?

Smooth muscle.

Which neurotransmitter is predominantly involved in the contraction of the detrusor muscle?

Acetylcholine.

What are the two main types of urinary incontinence identified in women?

Urodynamic stress incontinence and detrusor overactivity.

Which structure in the female lower urinary tract is primarily responsible for maintaining urine retention?

Urethra.

What is the typical maximum flow rate observed in a normal uroflowmetry test for women?

At least 15 ml/s.

What is detrusor overactivity characterized by?

Excessively high pressure from the bladder due to uncontrolled contractions.

How does the pelvic floor muscle training (PFMT) help in treating urinary incontinence?

It strengthens pelvic floor muscles to help close the urethra during increased abdominal pressure.

During which phase of urination does the detrusor muscle contract to expel urine?

Voiding phase.

Which type of incontinence is most commonly experienced by women?

Stress incontinence.

What role do stretch receptors in the bladder wall play during the storage phase?

They send signals to the brain indicating bladder fullness.

What is the typical age-related change in bladder function for older women?

Increased residual urine volumes and lower urine flow rates.

What is the pelvic floor's relationship to urinary incontinence?

Weakness or damage to pelvic floor muscles can lead to stress urinary incontinence.

What is the first sensation of needing to urinate typically felt at?

When the bladder holds around 150 to 300 ml of urine.

What is the significance of the pubourethral ligaments in urinary continence?

They support the upper urethra and maintain closure pressure.

Which hormonal changes are associated with increased urinary incontinence in postmenopausal women?

Decreased estrogen levels.

What is the average length of the adult female urethra?

3-5 cm.

What diagnostic test measures the pressure and volume relationship in the bladder?

Cystometry.

What is the pad test used for in the assessment of urinary incontinence?

To confirm incontinence by measuring pad weight gain after activities.

What is the relationship between childbirth and urinary incontinence risk?

Childbirth, especially vaginal delivery, increases the risk of urinary incontinence.

What is the main function of the rhabdosphincter urethrae?

To act as an intrinsic sphincter, helping to maintain continence.

What are common symptoms of overactive bladder (OAB) syndrome?

Urgency, frequency, and urge incontinence.

In urodynamic stress incontinence, what typically triggers involuntary urine loss?

Increases in intra-abdominal pressure without bladder contraction.

What is the most effective conservative treatment for mild stress urinary incontinence?

Pelvic floor muscle training (PFMT).

What is the role of the levator ani muscle in urinary function?

It provides support to the pelvic floor and contributes to urethral closure.

What is the typical bladder pressure limit during the filling phase to maintain continence?

Should not exceed 10 cm of water for 300 ml or 15 cm for 500 ml.

What is the threshold for considering urinary incontinence significant?

When it affects daily activities or is reported as bothersome by the patient.

Which condition is characterized by involuntary leakage during physical activities such as coughing or sneezing?

Urodynamic stress incontinence.

What physiological change occurs in the bladder during the voiding phase?

Inhibition of cortical control leads to detrusor contraction and urethral relaxation.
