013 Principles of Urologic Endoscopy Flashcards
Rigid cystourethroscopes are manufactured in sets consisting of an __, __, __, and __.
Rigid cystourethroscopes are manufactured in sets consisting of an OPTICAL LENS, BRIDGE, SHEATH, and OBTURATOR.
Flexible cystourethroscopes are available in __, __ and __ digital models.
Flexible cystourethroscopes are available in FIBEROPTIC, STANDARD-DEFINITION and HIGH-DEFINITION digital models.
Cystourethroscope sizes are expressed using the French gauge system, with 1 Fr equaling __ in circumference.
Cystourethroscope sizes are expressed using the French gauge system, with 1 Fr equaling A THIRD OF A MILLIMETER in circumference.
The __-diameter cystourethroscope that can be used to perform the procedure should be selected to decrease the risk of genitourinary tract trauma.
The SMALLEST-diameter cystourethroscope that can be used to perform the procedure should be selected to decrease the risk of genitourinary tract trauma.
__ is not recommended for diagnostic cystourethroscopy unless patient-related risk factors are present.
ANTIMICROBIAL PROPHYLAXIS is not recommended for diagnostic cystourethroscopy unless patient-related risk factors are present.
__ and __ have been prospectively shown to improve patient comfort during flexible cystourethroscopy.
INCREASING THE HYDROSTATIC PRESSURE DURING SCOPE PASSAGE and ALLOWING MEN TO OBSERVE THE PROCEDURE have been prospectively shown to improve patient comfort during flexible cystourethroscopy.
Semirigid ureteroscopy is used __ the iliac vessels and flexible ureteroscopy __.
Semirigid ureteroscopy is used BELOW the iliac vessels and flexible ureteroscopy ABOVE.
Semirigid ureteroscopes with two working channels permit __ and the added safety of being able to pass a lithotripsy device through one channel when needing to fragment a stone engaged in a basket in the other channel.
Semirigid ureteroscopes with two working channels permit BETTER IRRIGATION and the added safety of being able to pass a lithotripsy device through one channel when needing to fragment a stone engaged in a basket in the other channel.
Flexible ureteroscopes must be __ when passing a laser fiber or the working channel will be damaged.
Flexible ureteroscopes must be STRAIGHT when passing a laser fiber or the working channel will be damaged.
The golden rule of safe laser lithotripsy: “__.”
The golden rule of safe laser lithotripsy: “DO NOT STEP ON THE PEDAL IF YOU CANNOT SEE THE TIP OF THE FIBER IN CONTACT WITH THE STONE.”
Stone baskets made of __ maintain their shape, resist kinking, and allow disengagement of stones more reliably that stainless steel baskets.
Stone baskets made of NITINOL maintain their shape, resist kinking, and allow disengagement of stones more reliably that stainless steel baskets.
Ureteral access sheaths facilitate __ and __ during ureteroscopy.
Ureteral access sheaths facilitate REPEATED PASSAGE OF THE FLEXIBLE URETEROSCOPES and DECREASE THE INTRAPELVIC PRESSURE during ureteroscopy.
__ is preferred because of greater mobility, improved image quality, and less scatter radiation exposure to the surgeon compared with urology tables with fixed fluoroscopy units.
MOBILE C-ARM FLUOROSCOPY is preferred because of greater mobility, improved image quality, and less scatter radiation exposure to the surgeon compared with urology tables with fixed fluoroscopy units.
A routine __ should be given to all patients undergoing ureteroscopy.
A routine PREOPERATIVE ANTIBIOTIC should be given to all patients undergoing ureteroscopy.
__ should be used as irrigation during ureteroscopy to prevent absorption of a hypotonic solution.
NORMAL SALINE should be used as irrigation during ureteroscopy to prevent absorption of a hypotonic solution.
