Unit 4 Lower Urinary System Flashcards
What is the purpose of our Ureters?
- Carry Urine from renal pelvis to the bladder
True or false: Ureters lumens are narrow?
True
How long is a males urethra? Double check
8-10inches
How long is a female’s urethra? Double check notes
1-2inches
What is a reservoir for our urine?
- Bladder
What is our bladder capacity range?
600-1000mL
True or false: The bladder controls urination, micturition, and voiding?
True– basically all mean to pee
What is the detrusor muscle and why is it important?
- Located up in the wall of the bladder and remains laxed to allow the bladder to fill with urine. The muscle will contract during urination to aid in the release of urine.
True or false: Men typically encounter more problems with there detrusor muscle than women?
True- The problems– are typically when the muscle contracts even when the bladder is not full…
How does urine flow?
- Flows downward to prevent urine back flowing to kidneys
- Ureters connect to the bladder and have ureterovesical valves (one-way) valves that help urine not black flow into the kidneys
True or false: Urine does not create pressure on the bladder?
False- Pressure is created by urine in the bladder
Is urine sterile?
Yes
Is the PH of urine acidic or non-acidic?
Acidic
How is the prostate gland a protective mechanism to the bladder?
- Secretes antimicrobial fluid which helps kill bacteria
How is the normal flora of the vagina a protective mechanism to the bladder?
- Lactobacilli (the normal flora) keeps the vaginal wall and area surrounding acidic
What are the protective mechanisms in the bladder? (list 8) – FYI the answers to this card have also been broken into separate flashcards.
- Urine flows downward to prevent urine backflow into the kidneys
- ureters connect to bladder = ureterovesical valves (one-way valves)
- Muscles of bladder
- Pressure created by urine in the bladder
- Urine itself is sterile
- PH of urine is acidic
- Prostate gland- secretions help kill bacteria
- Normal flora of vagina- Lactobacilli

- Stress
- Urge

What is functional incontinence and what are some patient populations that are affected most by this type?
- Urinary tract system is functioning properly but due to an illness or disability the patient has urinary leakage….
- Patients with Alzheimer’s and dementia because they often forget to go so they do better when on a schedule. Patients on a large amount of diuretics may also suffer from this type of incontinences
What is stress incontinence?
- When physical movement or activity- coughing, laughing, sneezing, running, heavy lifting puts pressure (stress) on the bladder causing leakage of urine
What causes stress incontinence?
- Pelvic floor & urinary sphincter weaker
When are women at an increased risk for stress incontinence?
- after childbirth
When are men at an increased risk for stress incontinence?
- if they have prostate surgery
What are some devices that can help with stress incontinence?
- Vaginally pessary-device that fits over the urethra and puts pressure on the urethra to help urine from leaking, helps support bladder base
- Urethral insert- similar to tampon- inserted into the urethra to prevent leakage and removed after a certain time frame
What surgeries can help with stress incontinence?
- Vaginal sling - mesh like sling that is used to bring up bladder and urethra to help prevent leakage
- Injectable bulking agents
- Artificial sphincter
What are other names for urge incontinence?
- Overactive bladder
- Bladder spasms
- Irritable bladder
- Detrusor instability
What is urge incontinence?
Involuntary urination with little or no warning
What are some symptoms associated with urge incontinence?
- Frequent urination or nocturia
- Enuresis (bed-wetting)
What meds are used to treat incontinence?
Anticholinergics
What are anticholinergics used to treat?

- Can’t see, can’t pee, can’t spit, can’t shit…
- Anticholinergics dry everything up.
What should we know about oxybutynin (ditropan)
- It is an anticholinergic
- Decreases the urgency, frequency and nocturia in overactive bladder
3.
What are some DO NOT’s and NEED to know’s with anticolinergics?
- DO NOT use anticholinergics on a patient with BPH
- DO NOT give with decongestants (Claritin, benadryl, sudafed)
- CAN CAUSE hypertension
- Want these patients to be careful when they are excersing or in a hot tub. They do not sweat the same
What are some DO NOT’s and NEED to know’s with anticolinergics?
- DO NOT use anticholinergics on a patient with BPH
- DO NOT give with decongestants (Claritin, benadryl, sudafed)
- DO NOT use with patient with Glucoma
- CAN CAUSE hypertension
- Want these patients to be careful when they are exercises or when in a hot tub because they are more prone to dehydration since they do not sweat the same.
What are some common treatments for urinary incontinence?
- Kegal excercises
- Bladder retraining
- Botox injections
- Nerve stimulator
- Medications- anticholinergics
-Tolterodine (detrol)- Oxybutynin (ditropan)
What is Urinary Retention?
- Inability to empty bladder
True or false: There is acute and chronic types of urinary retention?
True
True or false: Acute urinary retention is not considered a medical emergency?
