AUA - Unit 3
What is important to obtain prior to performing PCNL? - answernon-contrast CT
What should you obtain prior to deciding if SWL or URS is appropriate for a patient? -
answernon-contrast CT
If you suspect a patient with kidney stones has had renal function loss in an affected
kidney, what should you get prior to discussing surgical options? - answerfunctional
study (DTPA or MAG3)
What is required prior to surgical intervention for kidney stones? - answerurinalysis (if
symptoms or signs of infection, obtain urine culture)
Who needs a CBC and platelet count prior to undergoing procedures for kidney stones?
- answer- significant risk of hemorrhage
- patients with symptoms concerning for anemia, thrombocytopenia, or infection
Who needs serum electrolytes drawn before undergoing procedures for kidney stones?
- answerpatients with suspicion of reduced renal function
When is contrast-enhanced imaging helpful in managing kidney stones? - answercan be
useful for patients with complex stones or complex anatomy
Who is an appropriate candidate for observation/ MET? - answeruncomplicated ureteral
stones <10mm in size.
Who benefits from alpha blockers during MET? - answer- patients with distal stones
- patients with stones >5mm
When is reimaging useful in patients trying to pass a stone? - answer- prior to
discussion of surgery if you think they passed it
- if stone movement changes management
When is the appropriate time to offer surgical management to a patient who was on
MET for a stone? - answer- failure to pass stone within 4-6 weeks
- decision of the patient or clinician to intervene sooner (shared decision making)
What is important to mention to patients when counseling them on SWL as an option vs
URS? - answer- SWL has ht lowest morbidity and lowest complication rate
- URS has a greater stone free rate from a single procedure compared to SWL
