CYSTOURETHROSCOPY
• Provides direct visualization- urethra and bladder
• Types : Rigid or flexible
• Rigid provides larger workshing channels, easier to control,
and better visualization
• Flexible provides patient comfort
Cystoscope
• Thin Telescope
• 2 types:
• Flexible - flexible, fibre-optic scope
• Rigid - solid, straight scope
Rigid Cystoscope
• Optical lenses come with tip angles ranging from 0 to 120 degrees.
• Visualization of the urethra is best performed with a 0- or 12-degree
lens.
• A 25- or 30-degree lens is commonly used for therapeutic purposes.
• A 70- or 120-degree lens may be required to completely inspect the
anterior and inferolateral walls, dome, and neck of the bladder.
Flexible Cystoscopes
• Contain fiberoptic bundles for illumination and visualization
• Has an irrigating channel and a working channel for passage of
instruments
• Can be deflected 180-220o
• Digital Flexible cystoscopes eliminate the need for fiber bundles
and the honeycomb pattern of the image
Advantages of rigid endoscope:
• Better optics
• Larger working channel allows
greater versatility in passage of
instruments
• Larger lumen for water flow, thus
improving visualization
• Ease of manipulation and
maintaining orientation during
inspection within the bladder
• Better for evacuating clots
Advantages of flexible endoscope:
• Greater comfort for the patient
• Ability to perform the procedure with the
patient in the supine position
• Ease of passing the instrument
over an elevated bladder neck
• Ability to inspect at any angle with
deflection of the tip of the instrumen
Lens
• 0O – for urethroscopy
• 30O - visualization of the base and anterolateral aspect of the
Bladder
• 70-90O - to view the bladder dome
• Retrograde lenses with an angle of view > 90O - visualize the anterior
bladder neck
Basiccomponents

• Cystoscope bridge
• Sheath & obturator

UPPER URINARY TRACT ENDOSCOPY
 Direct visualization of the upper urinary tract, facilitating
both diagnostic and therapeutic interventions
 Indication :
• Urolithiasis
• Upper urinary tract Transitional Cell Carcinoma
• Uretreropelvic junction obstruction
• Urethral stricture
Equipment
 Ureteroscopes
 Ancillary Equipment :
- Wires
- Ureteral Dilators
- Irrigation Systems
- Ureteral Access Sheaths
- Intracorporeal
Lithotriptors
- Stone Migration Devices
Instruments
• Telescope adapter
• Alligator Forceps
• Biopsy Forceps
• Scissor
• Hook Scissor
Common Supplies forUreteroscopy
PatientPreparation
• Informed consent must be obtained
• A urinalysis and urine culture, if indicated,
should be completed before cystoscopy  UTI
must be treated
• AUA : prophylaxis antibiotic is not recommended for
routine diagnostic procedure.
• For therapeutic  Chlorhexidine gluconate and
alcohol-based solutions are not recommended for use
on the genitalia
PatientPreparation
• In women, rigid cystourethroscope insertion is safest
using the sheath obturator
• In men, the penis should be angled 45 - 90° relative to
the abdominal wall while the scope is passed through
the anterior urethra.
• Visualization of the lateral walls is accomplished by
rotating the cystoscope while keeping the camera
orientation fixed.
• If a Foley catheter is to be placed after the procedure, it is
best to leave the bladder at least partially full before
removing the cystoscope.
Ureteroscopy Technique
Ureteroscopy Technique
• Upper tract imaging  IVP or helical CT scan
• UTI are treated preoperatively
• Routine preoperative antibiotic is give to all
patients fluoroquinolones or based on antibiotic
sensitivity test
• Patient in cystolithotomy position
Semirigid UreteroscopyTechnique
• Maneuvering the tip of the ureteroscope next to the
guidewire posterolaterally and elevate the wire 
propping the ureteral orifice open to allow scope
passage.
• If the intramural ureter is too tight to allow safe
passage of the ureteroscope, a dilating balloon
catheter can be used.
• Normal saline should be used for
irrigation to prevent accumulation and
absorption of hypotonic solution and
resultant TUR syndrome.
• Do not activate the laser unless the tip of
the fiber is seen to be contact with the
stone
Flexible UreteroscopyTechnique
Care andSterilization
• Scraped inner working channel  deflection of
flexible ureteroscope when the fiber is introduced
• Fired fiber within the working channel  to prevent the
tip must be seen in the central portion of the field of
view
• Should be cleased with warm water and a non
abrasive detergent after each use
