27.12: Urologic Endoscopic Procedure: Cystoscopic Examination

Meaning of Cystoscopic Examination:

Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:

• Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive nature.
• Rigid cystoscopy is used for more complex procedures and can be done in outpatient and hospital settings.

Indications for Cystoscopy:

Doctors recommend cystoscopy for the following conditions:

• Recurrent urinary tract infections (UTIs)
• Hematuria (blood in the urine)
• Frequent or urgent urination
• Urinary retention or obstruction
• Bladder stones
• Bladder tumors or polyps
• Urethral strictures

Pre-Procedure Preparation:

1. Patient Assessment:
   • Review the patient’s medical history, including allergies (especially to anesthesia or antiseptics), previous surgeries, and current medications (e.g., anticoagulants).
2. Informed Consent:
   • Explain the procedure, including its purpose, risks, and possible outcomes.
   • Ensure the patient understands the procedure and obtain written consent.
3. Diagnostic Preparations:
   • Routine tests like urinalysis, urine culture, and blood tests may be required.
   • If the patient will receive general anesthesia or sedation, fasting for several hours before the procedure is necessary. Patients undergoing local anesthesia do not need to fast.
4. Bladder Preparation:
   • The patient will likely be asked to empty their bladder before the procedure.

During the Procedure:

1. Anesthesia:
   • Local anesthesia: For flexible cystoscopy, a numbing gel is applied to the urethra to minimize discomfort.
   • General or regional anesthesia: Used for rigid cystoscopy or if therapeutic interventions, such as stone removal or biopsies, are anticipated.
2. Positioning:
   • The patient is placed in the lithotomy position, lying on their back with legs supported in stirrups.
3. Cystoscope Insertion:
   • The cystoscope, which is lubricated, is gently inserted into the urethra. The healthcare provider slowly advances the scope into the bladder.
4. Visualization:
   • Sterile saline or water is introduced into the bladder to expand it, allowing for a clear view of the bladder walls and urethra.
   • A camera attached to the scope transmits real-time images to a monitor, enabling the healthcare provider to examine the bladder and urethra lining closely.
5. Diagnostic or Therapeutic Actions:
   • The provider may take a biopsy, remove small stones or tumors, or perform other minor procedures if abnormalities are found.
   • The openings of the ureters, which drain urine from the kidneys to the bladder, are also inspected for any signs of obstruction.
6. Completion:
   • The scope is carefully withdrawn once the examination or treatment is complete and the procedure concludes.

Post-Procedure Care:

1. Monitoring:
   • Vital signs will be monitored for adverse reactions to anesthesia or the procedure.
   • Assess for any signs of infection, bleeding, or urinary retention.
2. Pain Management:
   • Mild discomfort, a burning sensation during urination, or blood in the urine is common after cystoscopy. Encourage the patient to drink plenty of water to flush the bladder and reduce irritation.
   • Pain relievers or antispasmodics may be prescribed to manage discomfort.
3. Observation for Complications:
   • Instruct the patient to report any symptoms, such as foul-smelling urine, chills, fever, or severe pain, as these could indicate infection or other complications.
4. Resumption of Activities:
   • Most patients can return to normal activities within 1 to 4 hours.However, strenuous activities or heavy lifting should be avoided for a few days, mainly if a biopsy is performed.
5. Urinary Catheter (if applicable):
   • If a urinary catheter was placed during the procedure, provide the patient with care instructions and a timeline for removal.
6. Follow-Up:
   • Emphasize the importance of a follow-up visit, especially if a biopsy was taken or further diagnostic evaluation is needed.
