FPMRS Exam Pro Flashcards
Complications of CIC (3)
urethral false passage,
possibility of silent deterioration of upper urinary tract, and bladder perforation from forceful
incorrect catheterization.
Bladder cancer has not been associated with CIC.
how often should you change an indwelling catheter
At least every 3 months
ways to reduce indwelling cath obstruction
- acidify urine (if patient’s urine output is not low otherwise crystal will form)
- treat infections with Proteus mirabilis and P. stuartii as these may obstruct
- use a silicon catheter

greater than 17Fr
How long to keep stent after ureteral injury?
4-6 weeks
steps for stent placement
30° scope → open-end cath → contrast → guide wire → stent → pusher.
What are the indications for indwelling cath?
H. - hematuria
O. - obstruction
U. - urologic surgery
D. - does patient have pressure ulcer or wound
I. - Input and output
N. - neurogenic bladder (patient who has long term inability to empty bladder such as spinal cord injury, etc.)
I. - immobilization (due to physical constraints or multiple fractures etc.)
bladder cancer recurence rate
50%
urothelial cancer: monoclonal theory vs field theory
monoclonal theory states that multiple tumors descend from a single genetically transformed cell that populates the urothelium.
The field theory states that exposure to a carcinogen leads to “cancerization” of the entire urothelium

Reliability of a questionnaire means?
Reliability is synonymous with reproducibility and repeatability. In other words, the level of agreement between measures either by the same individual, by different individuals, at same or different times is called reliability

how is it given?
Vyleesi- peptide and acts by activating the melanocortin receptors.
subq injection into the thigh or abdomen
side effects of vyleesi
nausea, pain at injection site, headache, and darkening of skin around gums, face, and breasts
FDA approved drug for hypoactive sexual desire disorder
vyleesi contraindication
HTN
FDA approved drug for hypoactive sexual desire disorder
Why are renal transplant patients at greater risk of Urinary frequency, nocturia, and bladder pain?
one theory is that they are anuria before the transplant and decreased bladder compliance.
then they start making urine after the transplant and the bladder is pissed.
60% of renal transplant patients develop frequency, nocturia and bladder pain
psych med that increases night time urine production?
lithium
other meds: alcohol, caffeine, diuretic, theophylline
definition of nocturnal polyuria
> 1/3 total urine is produced at night
Your patient has nocturnal polyuria and you want to diureses her before bed. What med can you prescribe and what time should she take it?
furosemide at 4-6pm
medical conditions besides DM, peripheral vascular disease, CHF that cause noturnal polyuria
low albumin, hypercalcemia
urethral bulking:
Animal source material that does not require skin testing prior to injection
Porcine dermal collagen (Permacol) does not need skin testing
bovine collagen (Contigen) does
How is skin testing done for bovine collagen urethral bulking?
skin test into the volar aspect of the forearm to be done at least 30 days prior to the urethral injection because 3% of patients will have a reaction indicating a pre-existing sensitivity to bovine dermal collagen through dietary exposure
off market since 2011
Why was Polytetrafluoroethylene (Teflon) removed from market?
bulking agent, removed due to particle migration and granuloma formation in distant organs, Particles size of < 80 micrometers
Durasphere
-What is it?
-What was the second generation modification?
Nonabsorbable carbon-coated zirconium beads suspended in a water-based polysaccaride carrier gel
-decreased particle size due to difficulty injecting large particles through 18 gauge needle. 212 to 500 micrometer–> 90 to 212 micrometers
urethral bulking material that can be injected without cystoscopy
macroplastiq - silicone microimplants
Why was Ethylene vinyl alcohol (Tegress) taken off the market in 2007?
stone formation, urethral erosion,
its a liquid that turns semi-solid when it comes into contact with water within the periurethral tissue cells.
5 indications for SNM
FI, non-obstructive urinary retention, Urgency, frequency, UUI
UDS findings
VLPP and MUCP to dx intrinsic sphincter deficiency

- Atrophic urethritis or vaginitis
- Psychologic
- Pharmaceuticals
- Endocrine / Metabolic (hyperglycemia, hypercalcemia)
- Restricted mobility
- Stool impaction
per AUA guidelines, basic eval for urinary incontinence
history

Steps for the pad test
how much to drink?
how many movements?
how many grams in one hour is postive
Test started without patient voiding first
Subject drinks 500cc (2 cups) of sodium free liquid
Must bend to pick up objects x5, cough x10, stand up x10, wash hands x30min, walks/stairs x30min
If pad saturated- weighed and another pad used
1g may be due to sweating/vag discharge
Change of >4g/ 24 hr is positive (1g/ 1 hour is a positive test)
No high correlation btw weight and UI severity
of leuks needed to dx pyuria by cytometry
By definition, “pyuria” is present when there are >10 leukocytes per MILLILITER on unspun urine by hemocytometer technique.
of leuks needed to dx pyuria by microscopic analysis
By definition pyuria is present when there are >3 leukocytes/HIGH POWER FIELD on unspun urine (by microscopy technique). Microscopy is not as sensitive as cytometry and thus just 3 leukocytes are enough to make the diagnosis of pyuria.
Which bacterial UTI results in false negative nitrite result on UA?
Staphylococcus saprophyticus, Pseudomonas species, or enterococci because they do not have he enzyme to convert nitrates into nitrites
enterobacter is the only bacteria that has the enzyme to convert nitrates into nitrites
Number of hours for bacteria to convert nitrate to nitrite at levels that are reliably detectable
4 hours for bacteria to convert nitrate to nitrite in the urine at levels that can be reliably detected, so the urine dip for nitrites is best done on the 1st void of the morning.
urine must be plated within ________ hours to to avoid exaggeration of CFU and a false positive.
If the urine specimen is not plated on the culture medium within 2 hours then the # of CFU/mL on the culture will be exaggerated and false positive results will be reported.
Number of positives on combined UA dipstick (WBC, RBC, nitrite) needed before treating a symptomatic patient
0, you can treat symptomatic patients even if UA is negative.
you send a urine culture for fungus. how amny hours of “no growth” do you wait before the test is considered negative?
48 hours for fungus
24 for bacteria
Minimum # of CFU/mL for Gram stain of unspun urine to be able to reliably detect bacteria
> 100k, gram stains are for complicated patients and you need an answer NOW
