What is the procedure for cystoscopy (cystoscopic examination) in females?

Cystoscopy Procedure in Females

Cystoscopy in females involves direct visualization of the bladder and urethra using a flexible or rigid cystoscope, with flexible cystoscopy being preferred due to less pain, fewer post-procedure symptoms, simplified patient positioning, and reduced procedure time. 1

Patient Preparation and Positioning

• Female patients are typically positioned in a frog-leg supine position for optimal access to the urethra 2
• The procedure requires sterile preparation including:
  • Flexible or rigid cystoscope (flexible preferred)
  • Irrigant solution
  • Lubricating gel
  • Sterile gloves
  • Sterile drapes 2

Procedural Steps for Female Cystoscopy

1. External Preparation:

   • Cleanse the external genitalia with antiseptic solution
   • Apply liberal amounts of lubricating gel to the cystoscope 2, 3

2. Urethral Access:

   • The female urethra is shorter (approximately 3-4 cm) compared to males, making insertion technically easier 1
   • Gentle separation of the labia for clear visualization of the urethral meatus 2
   • The cystoscope is inserted directly into the urethral meatus 2

3. Bladder Examination:

   • Complete visualization of the bladder mucosa, urethra, and ureteral orifices 1
   • Systematic inspection of the entire bladder including:
     • Trigone area (triangular region between ureteral orifices and bladder neck)
     • Lateral walls
     • Posterior wall
     • Dome of the bladder
     • Bladder neck area 2, 4
   • Assessment of ureteral orifices for patency and position 4

4. Irrigation:

   • Continuous irrigation is used to distend the bladder for optimal visualization 2
   • The irrigation fluid allows for clear visualization of the bladder mucosa 3

Equipment Considerations

• Flexible Cystoscopy: Currently considered the standard tool due to:

  • Significantly decreased pain and discomfort
  • Better visualization of certain areas (e.g., anterior bladder neck)
  • Improved patient tolerance 1, 3

• Rigid Cystoscopy: May still be used in certain circumstances but generally causes more discomfort 3

• Newer Technologies: Wireless cystoscopes with 4K ultra HD imaging are emerging, offering portability and lower cost 5

Clinical Applications

• Diagnostic evaluation for hematuria 1, 4
• Surveillance for bladder cancer 3
• Evaluation of lower urinary tract symptoms 1
• Assessment of urinary dysfunction 1
• Identification of bladder or urethral abnormalities such as:
  • Bladder tumors
  • Urethral diverticula
  • Interstitial cystitis
  • Foreign bodies 4

Post-Procedure Care

• Patients may experience mild discomfort or burning with urination
• Small amount of blood in urine may be normal immediately after the procedure
• Increased fluid intake is recommended to help flush the bladder 2

Common Pitfalls and Considerations

• Inadequate Visualization: Ensure proper irrigation and systematic examination of all bladder surfaces 2
• Patient Discomfort: Use of flexible cystoscope and adequate lubrication can minimize discomfort 1, 3
• Infection Risk: Maintain strict sterile technique to prevent urinary tract infections 2
• Anatomical Variations: Be aware of potential anatomical variations such as duplicated ureteral orifices or ureteroceles 4

For patients with urinary dysfunction, fluoroscopy voiding cystourethrography may be considered as an appropriate initial imaging study when imaging is deemed necessary after clinical evaluation 1.
